Problems solved by technology

[0006] Although the paints currently used in our country are still mainly low-end, the variety of acrylic paints in my country is relatively complete. Compared with developed countries, the gap does not lie in the variety of paints, but in the gaps in raw materials, production equipment, production technology and production scale.

Abstract

The invention relates to a preparation method of flame-retardant, antibacterial and waterproof waterborne acrylate resin. The method comprises steps as follows: walnut green husks are peeled, cleaned with water, dried to constant weight in an oven at the temperature of 40-60 DEG C, ground and screened by a sieve with 60-80 meshes, and walnut green husk powder is obtained; the walnut green husk powder and water are weighed, allyltrimethylammonium chloride, methyl 4-methoxyacetoacetate and tetrabutylammonium hydroxide are added for backflow and decoction for two times at the temperature of 80-90 DEG C, decocted liquids are combined, filtered and subjected to decompression concentration at a temperature of 60-70 DEG C until a concentrated liquid is in a thick paste shape with water content ranging from 15% to 20% and reaches the constant weight, and a walnut green husk extract concentrated liquid is obtained and applied to the acrylate resin. The obtained acrylate resin has good affinity with human bodies, good flame retardance and good waterproof property.

Description

technical field [0001] The invention relates to a preparation method of acrylic resin, in particular to a preparation method of flame-retardant, antibacterial and waterproof acrylic resin. Background technique [0002] Walnut green peel, also known as Qinglongyi, is a thick green peel on the outside of walnuts. my country's walnut cultivation area ranks first in the world, and the annual output of walnut green skin is more than 350,000 tons. After the walnut fruit is harvested, the green skin outside the nut should be removed as soon as possible. A large number of green skins become garbage and are piled up in the fields, fields or ditches to pollute the environment. If it is used, it can not only prevent environmental pollution, but also increase the income of fruit farmers. [0003] Green peel is the peel of walnut, which protects the seeds. Although it cannot be eaten, it also has certain biochemical effects: after research, its peel has obvious inhibitory effect on 5 k...
