Preparation of Flame Retardant Functional Boards from Waste Wood, Plastic Straw and Residue

Technical field:

The invention discloses a flame-retardant functional wood-plastic board prepared from waste wood, plastic, straw, and waste residue, and belongs to the technical field of preparation and production of flame-retardant functional wood-plastic boards prepared from agricultural waste.

Background technique:

Waste wood materials refer to waste wood, wood-based panels, waste paper and their products, which are recyclable resources. Among them, waste wood materials (including wood-based panels) refer to waste wood materials produced in the first and second wood processing industries, waste, damaged and useless wood materials produced in transportation, packaging, construction, civil engineering, etc. Renewed wood products (doors, windows, furniture), etc., including waste of wood processing products, waste wood-based panels, waste furniture, waste floors, frames of doors and windows, waste formwork, wood structural timber, wooden packaging and construction Waste wood abandoned at the time, paper splints, cable wooden trays, and imported materials as dunnage wood, driftwood, sleepers, materials disassembled from vehicles and ships, processing residues from wood processing enterprises, roads, trees renewed in urban garden systems, and There are toxic waste wood materials treated with chemical agents such as preservatives and flame retardants; all kinds of waste paper and cardboard. In foreign countries, waste wood and waste paper are called the fourth forest resource in the future, that is, the forest that falls on the ground.

Waste wood materials can be used for material recycling and energy utilization. Material recycling refers to secondary processing of waste wood after recycling to make various wood-based panels for reuse. Waste wood can also be made into activated carbon and industrial carbon. Or synthetic gas is used as a chemical raw material; the energy utilization of waste wood refers to using it as industrial fuel for boilers or power generation, and it can also be used for civilian household heating.

my country is a large agricultural production country. In agricultural production, there are many kinds of solid wastes such as straws, hard shells, waste residues, and huge oils. They are the main source of agricultural waste pollution in rural areas. The full and effective use of agricultural waste not only transforms it into useful industrial products, but also reduces environmental pollution and improves the rural ecological environment. Agricultural waste, as a kind of energy, is gradually entering a new stage of technology. Rational use and promotion of these technologies will surely produce good economic, ecological and social benefits.

With the rapid development of the plastics industry in the world today, its use has penetrated into various fields of the national economy. From industry and agriculture to basic necessities of life, plastic products are everywhere, and the application of plastic products has penetrated into every corner of society. Since plastic is difficult to degrade naturally, the environmental pollution it causes is also becoming more and more serious. Plastic agricultural mulch and plastic packaging materials are the most plastic waste. Over time, it becomes a shocking white pollution, causing serious pollution to the environment, even endangering human health and the survival of animals and plants, and affecting the ecological balance. The disposal of waste plastics has also become a global problem.

Although the conventional landfill method requires less investment and is easy to handle, it has disadvantages such as occupying a large amount of land resources, affecting land permeability and water seepage, destroying soil quality, and affecting plant growth. Although the incineration method has a reduction effect and can recover some resources, it will produce harmful gases such as hydrogen chloride, hydrogen cyanide, and nitrogen oxides during the combustion process. At the same time, hydrogen chloride will corrode equipment: polystyrene will produce a large amount of Harmful gas and black smoke. The discharged waste can enter the crops and food chain through rainfall, threatening human health.

my country is a big producer of wood and wood products in the world, as well as a big consumer, but the forest coverage rate in our country is less than 17%, and a large amount of waste paper, waste wood, old furniture and discarded wood-based panels are produced every year, about 90 million tons of living Garbage, of which waste wood materials account for about 4%, that is, the national production of waste wood materials is about 3.6 million tons. my country's annual construction completion area is about 1.2 billion cubic meters, of which only waste wooden building templates have more than 3 million cubic meters. To deal with these increasing waste wood materials will cost a lot of money including land occupation costs, transportation costs, landfill costs, etc., and there are also potential safety hazards and serious environmental pollution.

Waste wood materials can be used for both material recycling and energy utilization. Material recycling refers to the secondary processing of waste wood after recycling to make various wood-based panels for reuse, and waste wood can also be made into activated carbon, industrial charcoal or synthetic gas as chemical raw materials; the energy utilization of waste wood is It refers to using it as an industrial fuel for boilers or power generation, and it can also be used for domestic heating. At the same time, my country is a large agricultural country. There are many kinds of waste in agricultural production, especially solid matter, and the quantity is huge, mainly referring to plant fiber waste, which comes from farmland and orchard residues, such as straw, cotton stalks, and tobacco stalks. , sorghum stalk, sunflower stalk, rice straw, millet stalk, castor stalk, rape stalk, sesame stalk, soybean stalk, broad bean stalk, sweet potato stalk, cassava stalk, banana stalk, palm stalk, wheat straw, reed, sisal stalk (head ), hard shells, rice husks, peanut shells, coconut shells, sunflower shells, tea shells, fruit shells, rapeseed shells, scraps, bagasse, hemp chips, beet bagasses, tannin slag, ephedra slag, bamboo chips, etc. The full and effective use of agricultural waste not only transforms it into useful industrial products, but also reduces environmental pollution, improves the rural ecological environment, turns waste into treasure, and benefits the country and the people.

The invention is composed of waste lignocellulosic materials, fibers, hemicellulose, lignin, sawdust residues, and waste film from farmland, urban domestic waste, waste packaging bags, waste plastic lunch boxes, etc., including polyvinyl chloride, polyethylene, polypropylene and polypropylene. Fiber, polyester fiber, agricultural waste, various straws, rice, peanut shells, bamboo chips, bagasse, industrial waste, steel alkali waste slag, etc. are reinforced with anti-cancer, anti-cancer and immune-enhancing selenium-germanium elements. , it can automatically and continuously dissolve and release various elements of negative ions floating in the air under natural air temperature and sunlight conditions. When people absorb these effective elements and negative ions, they can promote the balance of human elements, strengthen the body and effectively prevent electromagnetic waves and radiation damage and radiate infrared rays that are beneficial to the human body. Through the production process of solubilization, blending and extrusion of these waste materials, injection molding and pressing, the preparation and production can replace wooden products and overcome the perishability, mold and insects of the original wood. Moth, low hardness, flammable, easy to absorb water, moisture and mildew, so that it can dissolve and release trace element negative ions to remove peculiar smell, fresh air, and flame retardant. It has high mechanical properties such as hardness, strength and sound absorption. Performance, widely used in construction, sound insulation panels, ceilings, floors, daily necessities, furniture and many other fields, it solves the environmental pollution of industrial and agricultural waste, the shortage of resources and the recycling and reuse of waste waste. It is a new type of green environmental protection. Versatile wood-plastic panels.

The gist of the technical scheme of the present invention is: the recovered waste polyethylene plastics are subjected to stimulation, screening, cleaning, purification, pulverization, granulation or modification, and combined with chitin, chitosan fiber, waste wood fiber, that is, shredded wood chips or wood Powder agricultural waste, straw shell, waste slag, ore materials such as medical stone and tourmaline through a 1200-mesh sieve, so that the specific surface area is large and the wood surface is fine and smooth, and then adding reinforcing modifiers, tackifiers, antioxidants, lubrication Agent, hair-linking agent, cross-linking agent, coupling agent, flame retardant, after washing, drying, crushing, kneading, agglomeration, melting of ingredients, and calendering, it can be made into green and environmentally friendly composite flame-retardant functional wood-plastic boards. Wood-plastic panels can release a variety of trace elements, radiate far infrared, resist electromagnetic wave pollution, spontaneously and continuously produce negative ions that are beneficial to human health, antibacterial and sterilizing, biodegradable, flame-retardant and will not cause environmental pollution Wood-plastic panels, Its application mechanism is: both chitin and chitosan come from the very hard parts of animal shells such as natural shells, crab shells, shrimp shells, fish bones and insects, and the N-acetyl group in the structural formula of chitin has been removed by 55 % or more, it becomes chitosan, the most important derivative of chitin. Chitin and chitosan have good adhesion, biocompatibility, biodegradability, natural antibacterial, non-toxic and harmless, no side effects, special adsorption, filtration, drug absorption, ion exchange, and It has a certain viscosity and good flexibility, strong antibacterial and antibacterial, anti-mildew and anti-oxidation, anti-moth, anti-electromagnetic wave, anti-static, sun-resistant, flame-retardant and fire-resistant green and environmentally friendly hybrid wood-plastic panels. Its production materials are entirely made of waste wood materials, leftovers, wood powder, urban or rural domestic garbage, waste plastic bags, waste lunch boxes, agricultural waste plastic films, agricultural waste, various straw hard shell waste bagasse and permanent flame retardants. Functional wood-plastic panels made of polymers. This wood-plastic panel not only has a variety of special functions, but also spontaneously and continuously releases trace element negative ions to promote human health. We know that negative ions in the air are very harmful to human health. Beneficial, it can make active acid disappear, eliminate acidity in the body, relieve fatigue, activate cells, enhance immunity, make the body comfortable, smooth blood, delay aging, improve insomnia and dry skin, and regulate the production of five serotonin (5HT) in the brain and blood In addition to its ability, it can also regulate the excitement and resistance of the central nervous system of the human body, improve the function of the cerebral cortex, and promote the body's metabolism. It has a very important impact on the life activities of human body and other organisms, and is called "vitamin in the air" and "longevity element". For this reason, it is very important to create materials and environments rich in negative ions. In order to achieve this goal, green and environmentally friendly composite multi-functional flame-retardant wood-plastic panels are made from recycled waste wood materials, waste plastics, agricultural waste, and stalks. The production method is to add a natural anion generator that can spontaneously and continuously generate anion , namely tourmaline or strange ice stone wood fish stone and other nano-powder minerals, zeolite sea, zeolite, diatomite, strange ice stone, can negatively ionize the water molecules in the air. The wood-plastic board is inlaid with negative ion powder and various mixed ultrafine nano-powders. Under certain external energy fluctuations, such as temperature, sunlight, friction, pressure, etc., the crystallization of negative ion powder or tourmaline The permanent positive and negative polarities at both ends of the powder, when in contact with ordinary water, water molecules in the air or water molecules on the surface of human skin, can produce an instantaneous discharge ionization effect, ionizing water molecules into H+ and OH-. H+ combines with the electrons released by the negative ion powder, namely tourmaline, and is neutralized into H atoms, while OH combines with other water molecules to continuously generate hydroxyl anions (H3O2)-. This is the main reason why negative ion powder, namely tourmaline nanopowder, can generate negative ions permanently and continuously. After this process, the water will appear in a weak alkaline that is beneficial to the human body due to the reduction of H+. Chitin fiber has a hydrophilic gene, contains 14% water rate, and has strong moisture permeability and permeability. Therefore, the negative ion function developed by the negative ion nanopowder of tourmaline, chitin viscose fiber produces more negative ions than synthetic fibers, The effect is more obvious, which is why the present invention selects chitin or chitosan to add tourmaline, strange ice stone, wood fish stone or other materials such as opal, zeolite, sea zeolite, diatomite, seaweed charcoal and other permanent spontaneous electrodes to generate carapace The mechanism of negative ions produced by plain or chitosan viscose fibers, and at the same time they also have an electromagnetic field. The natural ore contains SiO ₂ ·H ₂ O, TiO ₂ , Fe ₂ O ₃ , Al ₂ O ₃ , which are anti-electromagnetic wave pollution and Far-infrared radiating substances. Experiments have proved that this kind of far-infrared rays can promote human blood circulation, enhance human metabolism and immune function, and make human health. These ores are aluminum, sodium, iron, magnesium, and lithium rings characterized by boron. Structured silicate material, there are a large number of pore-like micropores in the ore, the pore density is high, the specific surface area is particularly large, the water absorption is extremely strong, and the adsorption is particularly good. It can adsorb chloride, nitrite, hydride, lead Pb , mercury Hg, arsenic As, cadmium Cd and other toxic and harmful substances, and can absorb water, moisture, and resist mildew and insects. Flame retardant, chitin, wood fiber, straw, and waste residue in wood-plastic panels. In this way, its specific surface area is particularly large, and its ability to absorb poisonous and harmful gases from bacteria and microorganisms is particularly strong. It releases trace elements, and the amount of spontaneous and continuous generation of negative ions is particularly large and high, because these ores are easy to dissolve a variety of trace elements after soaking in water. , gallium Ga, germanium Ge, selenium Se, strontium Sr, vanadium V, zinc Zn, copper Cu, molybdenum Mo, chromium Cr, nickel Ni, niobium Nb, tantalum Ta, cobalt Co, calcium Ca, magnesium Mg, potassium K, sodium Na, manganese Mn, titanium Ti, fluorine F, iron Fe, silicon dioxide SiO ₂ , titanium dioxide TiO ₂ , aluminum oxide Al ₂ O ₃ , ferric oxide Fe ₂ O ₃ , ferric oxide Fe ₃ O ₄ , iron oxide FeO, etc., can purify, activate and mineralize water when it meets water. Medical stone, Sanxian stone, snake mosquito stone are rich in trace elements, and infrared emitters such as TiO ₂ , SiO ₂ , Al ₂ O ₃ etc. The water after this process is not only weakly alkaline that is beneficial to the human body, but also releases harmful substances. A variety of trace elements that are beneficial to human health, negative ions, and far-infrared nanoparticles floating in the air can enter the human body through the human breath to supplement, regulate, and antagonize the balance of elements in the human body, thereby promoting human health and longevity.

Adding glass fiber in the embodiment is because the long-diameter ratio of wood flour is relatively small, and its own strength is not high, and the mechanical properties of wood flour reinforced composite materials still have a large gap with reinforced composite materials such as glass fibers. Therefore, its application The range is limited. In order to further expand the application range of such materials, it is necessary to try to improve their mechanical properties. The combination of wood powder and glass fiber to strengthen the polymer can improve the mechanical properties of the wood powder reinforced polymer material to a higher level, and at the same time improve the human body's sense of fit for the glass fiber reinforced polymer and improve the coating of the material. And bonding performance, and can reduce the density and cost of materials, and expand its application range.

Negative ion additives are composed of opal, tourmaline, mineralization plant, medical stone, wood fish stone, zeolite, sea zeolite, additives and other materials that can release element negative ions. Its function is to dissolve trace elements, release negative ions, antibacterial and antibacterial, Take drugs, filter drugs, get rid of all kinds of odors, and purify the air. Mildewproof, moistureproof, waterproof, mothproof, coupling agent can be silane coupling agent, bismaleic anhydride, maleic anhydride grafted polymer, etc. to promote the compatibility of polymer and wood flour, and improve the mechanical properties. The flame retardant can be magnesium hydroxide, magnesium salt crystal permanent flame retardant JLSUN, SCJ-968, 969, etc. Foaming agent can be AC, sodium bicarbonate, etc. Auxiliaries can be lubricants, plasticizers, etc., antioxidants, crosslinking agents, internal and external lubricants, etc. Natural antibacterial agents, chitin, chitosan natural antibacterial element supplements, selenium-rich germanium, spirulina and various factory waste residues, steel alkali slag, etc.
