Problems solved by technology

Although bamboo fiber products have certain antibacterial properties, they will still produce moldy spots after repeated use, which will affect the appearance and use
[0003] Adhesives can be widely used in many fields such as wood processing, architectural decoration, fabric bonding, etc., and the market is broad. However, most of the existing adhesives inevitably contain harmful substance formaldehyde. Free formaldehyde will be released after use, and the environmental performance remains to be seen. improve
[0004] CN102690618B (2013-12-4) discloses a preparation method of a thermosetting acrylic resin binder, but the binder is mainly used for glass wool and is not suitable for bamboo fiber products

Abstract

The invention relates to adhesives, particularly to a preparation method of an environment-friendly adhesive. The environment-friendly adhesive is composed of the following raw materials including, by weight parts, 70-95 parts of phthalic anhydride, furfuryl alcohol extracted from natural plant, triethylene glycol, pentanediol, butantriol, zinc oxide, magnesium oxide, chloroprene rubber and elastic rubber, 2-3 parts of softening oil, 20-30 parts of dimethyl carbonate, benzoyl peroxide, ethyl acetate, emulsifier and flour, 5*10-5-9*10-5 parts of nano silver, and fire retardant, wherein the elastic rubber is composed of first elastic rubber and second elastic fiber which are mixed at a weight ratio of 1-3:1. The preparation method of the second elastic rubber comprises heating polyvinyl alcohol solution and waterborne polyurethane water solution, cooling the mixture to 30-50 DEG C and then adding acrylate into the mixture; then adding potassium hydroxide into the mixture and heating the mixture; then adding cementum protein, abietin and plant phenols extracted from natural plant for reaction; then adding sodium benzoate, di-tert-butyl peroxide and the ethyl acetate and mixing the reactants to obtain the environment-friendly adhesive. The environment-friendly adhesive is good in bactericidal activity and high in stability, dispersibility and adhesiveness.

Description

technical field [0001] The invention relates to a binder, in particular to a preparation method of an environment-friendly binder. Background technique [0002] Bamboo fiber currently on the market has the following two classes: one is the regenerated fiber produced from bamboo pulp, commonly referred to as bamboo pulp fiber; the other is the fiber directly extracted from bamboo through a special process, called raw bamboo fiber. Because bamboo fiber has more superior properties in terms of hygroscopicity, air permeability, and spinnability, the study of spinnable bamboo fiber has obvious economic benefits and good social benefits. Although bamboo fiber products have certain antibacterial properties, they will still produce mildew spots after repeated use, which will affect the appearance and use. [0003] Adhesives can be widely used in many fields such as wood processing, architectural decoration, fabric bonding, etc., and the market is broad. However, most of the existin...
