technical field

The invention relates to the field of wood modification treatment for wood flooring, in particular to a strengthening modification treatment agent for wood flooring and a preparation method thereof.

Background technique

Wood flooring is a common home improvement material, mainly including solid wood flooring, laminate flooring, solid wood composite flooring, etc. Since wood, the core material of wood flooring, is a biomass material, it is flammable, perishable, easily deformed, and not durable Disadvantages such as humidity and heat severely limit its scope of use. It is necessary to carry out some pretreatment on wood to improve its resistance to the external environment and improve its environmental tolerance.

The existing wood modification methods mainly use some physical means to infiltrate the chemical modifier solution into the interior of the wood to improve the physical and chemical properties and finally improve its performance. However, some existing chemical modification methods after treatment In the subsequent use of wood, a large amount of volatile organic compounds may be emitted, which will cause harm to the surrounding environment. There are also disadvantages such as high cost of treatment agents, poor performance, and impact on decorative performance. It is urgent to develop a new type of wood. Environmentally friendly and efficient wood modifier, fundamentally improve the performance of wood flooring, and improve the shortcomings of traditional wood flooring.

The wood modifier of the present invention has the advantages that all raw materials are environmentally friendly ingredients, do not contain volatile organic compounds that are harmful to the environment and human body, and the preparation method is simple, and the production cost is low. Boric acid, melamine, sodium chloride, Modifiers prepared from raw materials such as mannitol can be evenly dispersed and adhered in wood after infiltrated into wood, so as to achieve the effect of improving the mechanical properties of wood. The resistance ability is stronger, the preparation method of the modified treatment agent of the invention is simple and easy to realize, the solution penetration is strong, the modification effect is long-lasting, the active ingredients are not easy to lose, the waste liquid is easy to recycle, and the wood floor made of modified wood has high strength. Durable and highly competitive in the market.

Detailed ways

Example

The modifying agent of this embodiment is made from the following raw materials in parts by weight (kg): 80% boric acid solution 18, trichloroisocyanuric acid 0.2, triethanolamine oleic acid soap 2, melamine 8, glycerin 30, coconut oil fatty acid diethanol Amide 5, sodium chloride 30, mannitol 12, water 350, auxiliary agent 8; the auxiliary agent is made of the following raw materials in parts by weight: water-based polyurethane emulsion with a solid content of 50% 12, sodium tripolyphosphate 3, sodium humate 5. Silica sol 2, secondary alcohol polyoxyethylene ether 2, eugenol 0.1, and water 30. The preparation method is: first mix sodium tripolyphosphate, sodium humate and water, stir until the mixture is completely dissolved, and then add Secondary alcohol polyoxyethylene ether, eugenol, and water-based polyurethane emulsion were stirred and dispersed for 30 minutes, then silica sol was added, and after stirring for 10 minutes, the mixed solution was ball-milled for 2 hours to make a stable solution to obtain the additive.

The modification agent preparation method of the present embodiment is:

(1) First mix melamine and glycerin, heat to 50-60°C, stir until completely dissolved, then add boric acid, continue stirring and mixing for 50 minutes, and cool the material to room temperature for later use;

(2) Add trichloroisocyanuric acid and sodium chloride into water together, stir until the materials are completely dissolved, then add the materials obtained in step (1) and other remaining materials, and stir at 1800 rpm for 2 hours to obtain the product.

In this example, Chinese fir veneer treated by impregnation with modifier is taken as an example. After drying fir veneer of the same specification at 50-60°C for 10 hours, they are divided into two groups, and the experimental group is soaked in the modifier at the same temperature. , soaked for 2 hours under the conditions of vacuum degree of -0.1MPa and pressure of 0.5MPa, took it out, washed the surface with water, dried it in the natural environment for 7 days, and finally baked it at 50-60°C to keep the moisture content at 5-6 %; the control group did not receive any treatment. The two sets of veneers enter the subsequent processing process to make laminate flooring.

Performance tests were performed on the modified fir veneer in the experimental group and the untreated control fir veneer. The results showed that the compressive strength of the fir in the experimental group was 26.4% higher than that in the control group. Trichoderma and black mold were inoculated on the wood surface. After that, the surface of the Chinese fir veneer in the experimental group was clean and free of hyphae, on the contrary, the surface of the Chinese fir veneer in the control group was severely moldy; the anti-extraction value of the Chinese fir veneer in the experimental group reached 88.7%, indicating that the wood treated with the modifier has good anti-loss resistance. , and the moisture absorption rate of Chinese fir in the experimental group is lower, which is 5.7% lower than that of the matched group; the results of the combustion experiment show that the heat release rate of the Chinese fir in the experimental group is reduced by 63.4% compared with the matched group, and the total heat release rate is reduced by 62.4%, which shows that the modified Chinese fir is improved by the present invention. The Chinese fir treated with additives has flame retardant properties and is safer.
