Abstract

The powerful adhesive includes neoprene, grafting monomer, thickener, dispersant, adhesion promoter, catalyst, antioxidant, solvent, stuffing, etc. The present invention also discloses the preparation process of the adhesive, and the preparation includes introducing grafting monomer to neoprene molecule chain to raise the adhesion strength, selecting proper adhesion promoting resin to increase the initial adhesion force, and adopting mixed solvent to form high adhering performance. The adhesive has high solid content and excellent environment protecting performance, and has also excellent antiageing performance, high resistance to heat, oil, chemical and corrosion, high weather resistance, good mildew-proof performance, antibiotic performance, etc. and may be used for adhering timber, concrete, rubber, metal, gypsum board, brick and other building material.

Description

technical field [0001] The invention relates to an adhesive used in building materials, in particular to a high-strength adhesive and a preparation method thereof. Background technique [0002] In the era of continuous improvement of home decoration, in order to achieve a beautiful and firm effect, more and more people hope that the decoration will no longer use nails and screws, but directly bond them with strong adhesives. Traditional adhesives can no longer meet the harmony and unity of safety and aesthetics of chemical materials required by people. In decoration, they either have great limitations in sticking to different materials; or because of unstable chemical properties, the residual harmful substances after bonding cannot reach the minimum standard of the national interior decoration materials. Some high-performance and high-quality adhesives and auxiliary products on the market cannot be produced or the product performance and quality can...
