Change sodium solution, the stirring and dissolving under heating water bath, heating-up temperature is 50-60 DEG C, and stirring obtains yellow solution in 30-40 minutes；
（2）Under nitrogen protection, epoxychloropropane is slowly added dropwise into there-necked flask, the reaction mol ratio with miscellaneous naphthalene Nomex is
n+2：N+1, reacts 4-6 hours under agitation, and reaction temperature is 55-65 DEG C, and obtaining product makes to be washed with deionized 3-5 times,
Acetone is reclaimed after adding acetone solution, filtering after decompression water removal, the sticky epoxy resin of refined yellow is obtained；
（3）Mass fraction by the sticky epoxy resin of the yellow prepared and excess is 30-40% acrylic acid solution in 70-
Heating response at 80 DEG C, reacts 2-3 hour, and it is dibenzoyl peroxide to react the catalyst that uses, is reacted after terminating, by except
It is miscellaneous to produce the epoxy modified aqueous acrylic acid ester.
Further described as to such scheme, described poly-vinyl alcohol solution mass concentration is 8-10%.
Further described as to such scheme, described defoamer is tributyl phosphate.
Further described as to such scheme, the preparation method of the varnish comprises the following steps：
（1）Epoxy modified aqueous acrylic acid ester, lauryl alcohol ester and sodium butylnaphthalenesulfonate, premixing are added according to the parts by weight
Afterwards, wetting agent, levelling agent, preservative and mould inhibitor are slowly added to, addition is scattered 10-15 minutes at a high speed after terminating；
（2）Ammonium persulfate regulation pH value is added into above-mentioned system, stirring is lower to add poly-vinyl alcohol solution thickening；
（3）Add defoamer de-soak；
（4）Add deionized water adjustment viscosity.
The present invention has advantages below compared with prior art：It is attached as the varnish of film forming matter in order to solve acrylic resin
Put forth effort that poor, chemical proofing is poor, cause the problem of durability of film is not good, the invention provides a kind of woodwork with resistance to
Long property varnish, by being modified to resin, the problems such as the drying property and relatively low viscosity of epoxy modified resin and aqueous acrylamide
After acid blending, performance is improved, and is learnt from other's strong points to offset one's weaknesses, and improves acrylic resin as the durability of the varnish of film forming matter, right
It is good in the adhesive force of timber, with excellent heatproof combustion resistance, water resistance, weatherability, moisture resistivity.
