Modified adhesive

Abstract

The invention discloses an adhesive and particularly relates to a modified adhesive. The modified adhesive consists of the following raw materials in parts by weight: 70-95 parts of elastic rubber, 25-35 parts of phthalic anhydride, 7-11 parts of furfuryl alcohol extracted from natural plant, 10-12 parts of triethylene glycol, 15-18 parts of glutaric acid, 8-10 parts of butantriol, 5-7 parts of zinc oxide powder, 3-5 parts of magnesium oxide, 15-25 parts of chloroprene rubber, 2-3 parts of softening oil, 15-20 parts of dimethyl carbonate, 1-3 parts of benzoyl peroxide, 4-8 parts of ethyl acetate, 1-4 parts of an emulsifier, 20-30 parts of flour, 5*10<-5>-9*10<-5> parts of nano sliver, 1-3 parts of a flame retardant, 0.8-2.5 parts of a catalyst, 3-7 parts of a bamboo vinegar aqueous liquid, 6-13 parts of bamboo carbon powder with grain size of 0.01-0.06mm, wherein the bamboo vinegar aqueous liquid is a mixed liquid of bamboo vinegar, a chelating agent and water in a weight ratio of 1 to (0.1-0.2) to (60-100); the bamboo carbon powder is prepared by the steps such as raw material pre-treatment, primary carbon preparation, activation treatment and pelletizing; the elastic rubber comprises first elastic rubber and second elastic rubber mixed in a weight ratio of (1-3) to 1. The adhesive has good antibacterial activity, stability and adhesion property.

Description

technical field [0001] The invention relates to a binder, in particular to a modified 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 existing adhesives inevitably contain harmfu...

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
