Abstract

The invention discloses an environment-friendly water-based adhesive. The water-based adhesive comprises the following raw materials in parts by weight: 30-40 parts of acrylic acid modified amino-terminated water-soluble hyperbranched polyamide, 10-15 parts of (chloromethyl)boronic acid pinacol ester ionic-modified N,N'-bis(2-hydroxyethyl)-N,N'-bis(trimethoxysilylpropyl)ethylenediamine / hydrogenated acrylic acid rosin, -3-6 parts of triethoxysilyl propyl maleic acid, 5-10 parts of polyethylene glycol diacrylate, 4-8 parts of attapulgite, 1-3 parts of fullerene-based carbon quantum dots, 0.5-1.5parts of an emulsifier, 25-35 parts of deionized water, 3-6 parts of a cosolvent, 1-3 parts of a photoinitiator and 0.5-1 part of a coupling agent. The invention also discloses a preparation method of the environment-friendly water-based adhesive. The environment-friendly water-based adhesive disclosed by the invention has the advantages of good water resistance, higher peel strength, sufficientinitial adhesion, excellent water resistance and weather resistance, good storage and transportation stability, safer use process, greenness, environmental protection and high economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly water-based adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy and social progress, people's living standards have gradually improved, and people's requirements for quality of life have become higher and higher. Higher requirements are put forward for the performance of adhesives for bonding, not only requiring high bonding strength, but also requiring good water resistance, heat resistance, weather resistance, and good performance stability. Environmental protection requirements during the preparation and use of adhesives are becoming more and more stringent. [0003] Adhesive is a natural or synthetic, organic or inorganic substance that connects two or more parts or materials together through interface adhesion and cohesion. At present, the common adhesives...
