Problems solved by technology

[0005] Although the paints currently used in my country are still mainly low-end and medium-grade, 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 provides a preparing method of flame-retardant, anti-bacterial and waterproof graphene modified acrylate resin paint .After being stripped, walnut green peels are cleaned with water, placed into an oven to be dried at the temperature of 40-70 DEG C to the constant weight, smashed and screened through 80-100 meshes to obtain walnut green peel powder, the walnut green peel powder and water are weighed, allyl trimethyl ammonium chloride and 4-methoxy methyl acetoacetate are added, the mixture is subjected to backflow decoction at the temperature of 80-100 DEG C, decoction liquid is filtered and subjected to pressure-reduction concentration at the temperature of 60-70 DEG C, and walnut green peel extract concentrate is obtained after the decoction liquid is concentrated into dense paste with the water content being 15-20%, and applied to acrylic resin .The obtained acrylic resin has good anti-bacterial, flame-retardant and waterproof properties .

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] 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 kinds of human pathogenic bacteria, and the antibacterial effect is different. The antibacterial effect on Staphylococcus epidermidis was the best, with a bacteriostatic rate of 83.3%; followed by Staphylococcus aureus, Salmonella choleraesuis, and pneumococcus, with bacteriostatic rates of 75.4%, 70.2%, and 62.6% respectively; Bacteria effect is poor, 41.1%. A total of 24 volatile components were identified through the analysis of the volatile substances in the green pecan peel. [0003] At present, the variety of acrylic resin in my country has been relatively perfect, ...
