Abstract
The present invention relates to a light material made from waste slag, mud and waste and old glass. The light material is characterized in that the light material is made from the waste slag, the mud and the waste and old glass. The material has the components of the following weight percentage: 10 to 30 wt% of old glass and waste slag, 50 to 80 wt% of mud and 5 to 20 wt% of additive. The additives comprise a foaming agent, a fluxing agent and a stabilizer. Since the light material adopts industrial and domestic wastes and mud besides a small amount of additives, the made material has a unique structure, and has the physical properties of low density, high intensity, low heat conduction coefficient and the like. The light material can be widely used in the fields of chemical industry, buildings, communication, electric power, refrigeration, etc.
Description
(1) technical field
The present invention relates to a kind of material, the light material of particularly a kind of waste residue, mud and discarded glass preparation.
(2) background technology
The various waste residues that all trades and professions produced are serious environment pollution not only, and causes the loss and the waste of a large amount of available resources.The final outlet that solves the resource environmental pollution is exactly the regeneration and the utilization of changing rejected material to useful resource.According to incompletely statistics, China has 2,000,000 tons of cullet not to be utilized every year, and the generation of China's cast used sand is very big, approximately with annual 160 tons of speed discharging, factory in some big and medium-sized cities all exists antiquated sand, slag and dumps stacking and not only spent but also problem of environment pollution caused.Utilize discarded object to make the new material of high added value, can protect environment, can economize on resources again.
(3) summary of the invention
The objective of the invention is to propose a kind of new technical scheme of utilizing waste residue, mud and discarded glass etc. to make the light material that can be widely used in chemical industry, building, traffic, electric power and refrigeration field for primary raw material.
Technical scheme of the present invention is to implement like this, and the light material of a kind of waste residue, mud and discarded glass preparation is characterized in that being made by waste residue, mud and discarded glass its material weight percentage:
Cullet: 10～20%
Waste residue, mud: 60～80%
Additive: 10～20% additives are blowing agent, flux, stabilizing agent.
Technical scheme of the present invention can also be implemented like this, and blowing agent is: carbonate, silicates, flux is: phosphoric acid salt, borate family, stabilizing agent is: phosphoric acid salt.
Enforcement by above technical scheme has reached purpose of the present invention substantially.Main cullet, industrial residue and the mud of utilizing of the present invention is made light material for primary raw material, these materials can be cullet, waste residue, additive, or cullet, mud, additive, also can be the multinomial combination of cullet, waste residue, mud, additive etc.Material of the present invention all adopts discarded object as raw material except that additive.Blowing agent is made up of carbonate, silicate in the additive, as sodium carbonate, sodium metasilicate etc.; Flux is made up of phosphate, borate, as sodium phosphate, borax etc.; Stabilizing agent phosphate is formed, as sodium phosphate etc.Such one is the secondary utilization that has realized resource; The 2nd, made material has unique internal structure, has physical propertys such as density is little, intensity is high, thermal conductivity factor is little, makes material have functions such as insulation, heat insulation, sound absorption, fire prevention, protection against the tide.It can extensively be used in fields such as chemical industry, building, traffic, electric power, refrigeration.
Light material with waste residue, mud and discarded glass preparation is a kind of novel environmentally conscious materials.This is a kind of by the heterogeneous light material of forming.The matrix of material is aluminosilicate glass or Pyrex mutually, it is present between wild phase and the gas phase, occurs mutually as the wild phase granular boundary, and formed rack between the wild phase particle, and particle is bondd effectively, thereby give material high mechanical strength.Wild phase is silica or alundum (Al particle, and it is the main component of composite, strengthens the particle contact position and is connected by the rack of matrix phase, and what have is soaked into corrode.Gas phase is countless small bubbles.It is the most distinctive feature in this light material, and majority is present between the enhancing particle, is often surrounded by the matrix phase on every side.Isolatedly between the bubble exist or be interconnected.
This characteristics of light materials is different from simple glass.It has physical propertys such as density is little, intensity is high, thermal conductivity factor is little, makes it give functions such as insulation, heat insulation, sound absorption, protection against the tide, fire prevention.Also have many premium properties of being given by inorganic glass materials simultaneously, the nearly all chemical erosion of ability except that hydrofluoric acid can oxidation, non-efflorescing cementitious rotting, the rat eaten of not damaged by worms has good chemical stability, other article there is not corrosiveness, nontoxic, "dead" injury.Even under high-temperature fusion, can not be decomposed or emit harmful substance yet, can directly make the polychromy goods that never fade, also can not wear out by ultraviolet ray and heat radiation.The premium properties that this composite had will more and more be subject to people's attention.It is to utilize solid waste to carry out resource, and obtains one of effective way of social benefit, economic benefit, environmental benefit.
The invention will be further described below with reference to embodiment.

Accompanying drawing 1 is a process chart
Accompanying drawing 2 is sintering curve figure
(5) specific embodiment
Example one
Cast waste sand: 80%
Cullet: 10%
Additive: 10%
Wherein: sodium carbonate: sodium phosphate: borax=6: 2: 2
900 ± 10 ℃ of sintering temperatures, constant temperature 1 hour.
Waste residue, mud and discarded glass the like waste need carry out preliminary treatment, waste residue through magnetic separation again through fragmentation, grinding, reach the required granularity requirements of technology after selecting powder processing; Mud is through dehydrating, make slag, again through fragmentation, grinding, reach the required granularity requirements of technology after selecting the powder processing; Discarded glass passes through cleaning, fragmentation, selects powder to reach the required granularity requirements of technology.Take by weighing waste residue, sludge silt and discarded glass and blowing agent, flux, foam stabilizer etc. by processing compound, evenly mix the back and form batch, the batch sintering mold of packing into, put into sintering furnace, under suitable sintering atmosphere, be prepared into light material through sintering processes such as low-temperature prewarming, high-temperature fusion, foaming, steady bubble, annealing.The material of being produced can cut into the shape of different size according to different demands.Also can adopt the method for changing sintering mold to obtain.
Example two
Cast waste sand: 30%
Cullet: 20%
Sludge silt: 30%
Additive: 20%
Wherein: sodium carbonate: sodium phosphate: borax: waterglass (sodium metasilicate)=6: 2: 2: 10
Manufacture craft such as embodiment 1.
