Auxiliary agent is made by 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.

Described long-acting modification agent for a kind of timber floor timber, its preparation method is:

(1), first by Grape Skin and white spirit mixed, airtight immersion 5-6 days, soaks and finishes rear material filtering, filtrate for later use;

(2) methyl acrylate and mixed with propylene glycol is evenly standby;

(3) alkyl polyglucoside, zinc chloride, neopelex, urea are mixed with water, be stirred to after dissolving completely, add step (1), (2) gained material and other leftover materials, with the rotating speed of 1500-1800 rev/min, stir 1-2h, obtain.

Wood modifier advantage of the present invention is: the raw material adopting is environmental protection composition, not containing volatile toxicant, can not work the mischief to environment and human body, production process is simple, and cost is low, in preparation method, utilize soaking in Chinese liquor Grape Skin, simply extract efficiently active ingredient wherein, reach the effect of anti-oxidation and antisepsis, Grape Skin after immersion can also recycle, and avoids the wasting of resources; In addition, the raw materials such as the methyl acrylate in raw material, alkyl polyglucoside, zinc chloride, urea, infiltrate through behind timber inside, can be good at adsorbing mutually with lumber fibre, reach and improve dimensional stability, moisture retardant texts, the timber mechanics performance after modification agent modification of the present invention obtains and promotes, modifier is difficult for running off, modified effect is lasting, and the timber after modification is more durable in use with the floor of material, and the market competitiveness is strong.

The specific embodiment

Embodiment

The modifier of the present embodiment by following weight portion (kilogram) raw material make: propane diols 12, methyl acrylate 13, alkyl polyglucoside 8, gallic acid 12, zinc chloride 2, Grape Skin 2, white wine 15, neopelex 4, urea 40, water 400, auxiliary agent 8; Auxiliary agent is made by the raw material of following weight portion: the aqueous polyurethane emulsion 12 that solid content is 50%, sodium phosphate trimer 3, sodium humate 5, Ludox 2, secondary alcohol APEO 2, Eugenol 0.1, water 30, 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.
