Auxiliary agent is made up of the raw material of following weight portion: the aqueous polyurethane emulsion 10-12 that solid content is 50%, sodium phosphate trimer 1-3, sodium humate 4-5, Ludox 2-3, secondary alcohol APEO 1-2, Eugenol 0.1-0.2, water 30, its preparation method is: first by sodium phosphate trimer, sodium humate mixes with water, being stirred to mixed material dissolves completely, add subsequently secondary alcohol APEO, Eugenol, aqueous polyurethane emulsion, dispersed with stirring 20-30min, add again Ludox, stir after 10min, mixed solution ball milling 1-2h, make stabilizing solution, obtain auxiliary agent.

Strengthening modification agent for described a kind of timber floor timber, its preparation method is:

(1) first melamine is mixed with glycerine, be heated to 50-60 DEG C, be stirred to after dissolving completely, then add boric acid, continue to be uniformly mixed 40-50min, it is for subsequent use that material is cooled to room temperature;

(2) sym-closene, sodium chloride are added to the water together, after being stirred to material and dissolving completely, then add step (1) gained material and other leftover materials, stir 1-2h with the rotating speed of 1500-1800 rev/min, to obtain final product.

Wood modifier advantage of the present invention is: all raw materials are environmental protection composition, containing the volatile organic matter that environment and human body is had to harm, and preparation method is simple, production cost is lower, with boric acid, melamine, sodium chloride, modifier prepared by the raw materials such as sweet mellow wine infiltrate after timber can be in wooden dispersed adhering to, thereby reach the effect of improving timber mechanics performance, the timber of modification is firm pliable and tough, good stability of the dimension, be difficult for imbibition dry and cracked, the defensive ability/resistance ability of environment is stronger to external world, this invention modification agent preparation method is simple and easy to realize, solution penetration is strong, modified effect is lasting, active ingredient is difficult for running off, waste liquid easily recycles, the timber floor intensity that timber after modification is made is high, durable in use, the market competitiveness is strong.

Detailed description of the invention

Embodiment

The modifier of the present embodiment by following weight portion (kilogram) raw material make: 80% BAS 18, sym-closene 0.2, trihydroxy ethylamine oleate soap 2, melamine 8, glycerine 30, cocoanut fatty acid diethanolamide 5, sodium chloride 30, sweet mellow wine 12, water 350, auxiliary agent 8; Auxiliary agent is made up of the raw material of following weight portion: aqueous polyurethane emulsion 12, sodium phosphate trimer 3, sodium humate 5, Ludox 2, secondary alcohol APEO 2, Eugenol 0.1, water 30 that solid content is 50%, its preparation method is: first sodium phosphate trimer, sodium humate are mixed with water, being stirred to mixed material dissolves completely, add subsequently secondary alcohol APEO, Eugenol, aqueous polyurethane emulsion, dispersed with stirring 30min, add again Ludox, stir after 10min, mixed solution ball milling 2h, make stabilizing solution, obtain auxiliary agent.
