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, ...
