Problems solved by technology

[0002] Willow is the main source of wood in the domestic market. With the increasing demand for wood in our country, there are more and more technical requirements for willow. Because willow itself is light in material, it is more and more popular in making woven handicrafts. Due to the flammability of willow itself, there is a fire hazard when using willow handicrafts, and the anti-corrosion performance of willow itself is weak. If it encounters rainy weather in the south, it is prone to decay, mildew, and is not durable.

Abstract

The invention discloses a preparation method of anti-corrosion and flame-retardant willow. The preparation method comprises the following steps that (1), log is sawed and cut into pieces and treated into strips, burrs on the side edge of the willow is ground flat, and the width of a single willow strip is 2-4cm; (2), the willow strips treated in the step (1) are placed into -25 DEG C for rapid freezing for 10-15min, the willow strips are taken out and put into flame retardant liquid of 30-40 DEG C for soaking for 12-24h, and then the willow strips are put into anti-corrosion liquid of 30-40 DEG C for soaking for 12-24h; (3), the willow strips soaked in the step (2) are dried, the drying temperature is 60 DEG C, the moisture content is 30-40%, the temperature is lowered to 50 DEG C, the heat preservation is performed for 20-30min, and the drying is completed when the moisture content is reduced to less than or equal to 10%; and (4), the willow strips treated in the step (3) are subjected to gumming, hot-press treatment and then subjected to cold dry, after cold dry, the flame retardant liquid is crisscross uniformly sprayed on the surface of the willow strips, and the willow is obtained after being naturally air-dried. The willow obtained by the preparation method has good anti-corrosion and flame retardant effect and is harmless to bodies.
