Auxiliary agent is made up of the raw material of following weight portion: solid content is the aqueous polyurethane emulsion 10-12 of 50%, sodium tripolyphosphate 1-3, sodium humate 4-5, Ludox 2-3, secondary alcohol polyoxyethylene ether 1-2, eugenol 0.1-0.2, water 30, its preparation method is: first by sodium tripolyphosphate, sodium humate mixes with water, stirring to mixed material is completely dissolved, it is subsequently added secondary alcohol polyoxyethylene ether, eugenol, aqueous polyurethane emulsion, dispersed with stirring 20-30min, add Ludox, after stirring 10min, mixed solution ball milling 1-2h, make stable solution, obtain auxiliary agent.

Described a kind of timber floor timber anti-seepage fire-retardant modification agent, its preparation method is: be first added to the water by diammonium phosphate, after stirring is completely dissolved to it, add calcium sulfate, Nafusaku, sodium metnylene bis-naphthalene sulfonate, cellulose ether, continue stirring to material to be completely dissolved, it is eventually adding other leftover materials, stirs 2-3h with the rotating speed of 1500-1800 rev/min, to obtain final product.

The Wood modifier advantage of the present invention is in that: all of raw material is environmental protection composition, without the volatile ingredient that environment and human body are had harm, and preparation method is simple, production cost is relatively low, with calcium sulfate, Nafusaku, guaiacol, modifying agent prepared by the raw materials such as cellulose ether penetrates into after timber can dispersed attachment in wooden, timber gap can be filled in after drying, increase dense structure's property, greatly improve the impermeable ability of timber, the defensive ability/resistance ability of environment is higher to external world, and these effective ingredient not easily run off, wood dimensional stability is good, not easy to crack, this invention modification agent preparation method simply easily realizes, solution penetration is strong, modified effect is lasting, do not affect the grain of wood and Se Ze, reusable, free from environmental pollution, the timber floor that modified timber makes is durable in use, water proof fire retardant, security performance is good, the market competitiveness is strong.

Detailed description of the invention

Embodiment

The modifying agent of the present embodiment is prepared by the raw material of following weight portion (kilogram): calcium sulfate 0.1, Nafusaku 0.02, sodium metnylene bis-naphthalene sulfonate 5, guaiacol 0.1, cellulose ether 12, diammonium phosphate 38, sodium methyl silicate 0., water 400, auxiliary agent 8; Auxiliary agent is made up of the raw material of following weight portion: solid content be 50% aqueous polyurethane emulsion 12, sodium tripolyphosphate 3, sodium humate 5, Ludox 2, secondary alcohol polyoxyethylene ether 2, eugenol 0.1, water 30, its preparation method is: first sodium tripolyphosphate, sodium humate are mixed with water, stirring to mixed material is completely dissolved, it is subsequently added secondary alcohol polyoxyethylene ether, eugenol, aqueous polyurethane emulsion, dispersed with stirring 30min, add Ludox, after stirring 10min, mixed solution ball milling 2h, make stable solution, obtain auxiliary agent.

The preparation method for modifier of the present embodiment is: be first added to the water by diammonium phosphate, after stirring is completely dissolved to it, add calcium sulfate, Nafusaku, sodium metnylene bis-naphthalene sulfonate, cellulose ether, continue stirring to material to be completely dissolved, it is eventually adding other leftover materials, stir 3h with the rotating speeds of 1800 revs/min, to obtain final product.

The present embodiment is for modifying agent Immersion treatment Lignum seu Ramulus Cunninghamiae Lanceolatae veneer, after the Lignum seu Ramulus Cunninghamiae Lanceolatae veneer of same specification is dried 10h under 50-60 DEG C of condition, being divided into two groups, experimental group is soaked in synthermal modifying agent, is-0.1MPa in vacuum, pressure impregnates 2h when being 0.5MPa, take out, after the washing of surface, dry 7 days in natural environment, last baking under 50-60 DEG C of condition, keeps moisture content at 5-6%;Matched group is left intact. Two groups of veneers enter subsequent processes, make laminated flooring.

Modified experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae veneer and undressed matched group Lignum seu Ramulus Cunninghamiae Lanceolatae veneer carry out performance test respectively, result shows, experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae comprcssive strength relatively matched group timber improves 20.3%, inoculate Trichoderma spp. and black mould at wood surface after, the clean aseptic silk in experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae veneer surface, otherwise, matched group Lignum seu Ramulus Cunninghamiae Lanceolatae surface from mildewing is serious; The anti-lixiviate value of experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae veneer reaches 86.7%, it was shown that the timber after modifier treatment has the resistance leachability resisted, and the moisture absorption ratio of experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae is lower, reduces by 12.3% than matched group; Results of combustion tests shows, experimental group Lignum seu Ramulus Cunninghamiae Lanceolatae HRR relatively matched group reduces by 62.3%, and total heat liberation rate, heat release rate reduces by 61.5%, illustrates that the Lignum seu Ramulus Cunninghamiae Lanceolatae after modified by this invention dose of process has fire resistance, and safety is higher.
