AI Technical Summary

Problems solved by technology

However, most of the existing construction adhesives are oily. After construction, the organic solvent will volatilize into the outdoor air or indoors, and most of the organic solvents are relatively toxic, which will have a very large impact on the environment and the human body. There are also a small amount of water-based adhesives on the market, but the existing water-based adhesives have many shortcomings such as poor waterproof performance and low strength.

Abstract

The invention discloses an environment-friendly building water-based adhesive. The environment-friendly building water-based adhesive comprises, by mass, 45-55 parts of acrylic acid, 60-70 parts of styrene, 15-22 parts of butyl acrylate, 8-14 parts of methyl methacrylate, 1-5 part of hydroxypropyl methyl cellulose, 6-12 parts of polyvinyl alcohol, 2-5 parts of emulsifier, 0.9-1.5 parts of initiator, 2-6 parts of pH regulator, 40-50 parts of inorganic salt powder and 160-220 parts of deionized water. The adhesive does not contain an organic solvent, that is, the adhesive is free of toxic substances such as benzene, toluene and formaldehyde, and the adhesive is excellent in water resistance and waterproof performance, high in strength, high in binding property and excellent in comprehensiveperformance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally-friendly building water-based adhesive. Background technique [0002] The environment is the basic premise for human survival and development. The environment provides the necessary resources and conditions for our survival and development. With the development of social economy, environmental issues have been put on the agenda of governments of various countries as an unavoidable and important issue. Protecting the environment, reducing environmental pollution, and curbing the trend of ecological deterioration have become our common tasks. [0003] Now construction glue is widely used in construction engineering and is an indispensable material in construction engineering. However, most of the existing construction adhesives are oily. After construction, the organic solvent will volatilize into the outdoor air or indoors, and most of the organic solvents ...
