Environment-friendly water-based chloroprene universal rubber and preparation method thereof

Abstract

The invention discloses environment-friendly water-based chloroprene universal rubber and a preparation method thereof. The universal rubber comprises the following main components in percentage by weight: 5% of a water-based rosin glycerol ester emulsion, 5.4% of a water-based pentalyn emulsion, 4% of a water-based petroleum resin emulsion, 8% of a water-based alkyl phenol emulsion, 11% of a water-based acrylic emulsion, 8% of a water-based EVA (Ethylene Vinyl-Acetate) emulsion, 42% of water-based anionic chloroprene latex and 6% of deionized water. The universal rubber disclosed by the invention has the comprehensive advantages of zero VOC (Volatile Organic Compounds), high solid content, no organic solvents, no heavy metals, no taste, excellent binding performance, heat-resistance and aging-resistance, shorter drying time, long open time, excellent leather grease resistance, rubber saving and the like, has the advantages of avoiding environmental pollution, improving the operation and construction environments, being low in cost, tasteless, fireproof and safe and the like, and can be widely applied to panel decorative industries such as aluminum-plastic panels, clamp boards, density boards, paint-free boards, macromolecular panels, screens and metal sheets. The environment-friendly water-based chloroprene universal rubber is especially suitable for being applied to green and environment-friendly top-grade decorative industries.

Description

technical field [0001] The present invention relates to an adhesive and a preparation method thereof, more specifically to an environmentally friendly water-based chloroprene type universal adhesive and a preparation method thereof, which can be widely used in aluminum-plastic panels, splints, density boards, paint-free boards, wood boards, Polymer boards, screens, metal sheets, EVA and other board decoration industries, especially suitable for green environmental protection high-end decoration industries. Background technique [0002] Universal glue is a kind of adhesive with suitable viscosity, which is suitable for scraping and brushing construction with toothed squeegee and brush as construction tools, and closely connects the interfaces of two different substances to play the role of transfer application; Universal adhesives are widely used in the bonding of aluminum-plastic panels, plywood, density boards, paint-free boards, polymer boards, metal sheets and other mater...

AI Technical Summary

Problems solved by technology

[0003] At present, the Chinese market is still dominated by medium and low-end solvent-based universal adhesive applications. A large number of organic solvents include toxic halogenated hydrocarbons and triphenyls (benzene, toluene, xylene ) solvent enters the air during construction, which not only consumes a large amount of increasingly tense petroleum oil resources, but also seriously affects people's living environment and health; although the country began to implement the national standard GB 18583-2008 (interior decoration) on September 1, 2009 Mandatory limits for harmful substances in adhesives for decoration materials), but the limits for triphenyl and halogenated hydrocarbons are still too loose, for example: toluene + xylene ≤ 15%, low-toxic halogenated hydrocarbons dichloromethane ≤ 5%, according to European and American standards For the high standards of environmental protection in western developed countries such as Japan, the GB 18583-2008 national standard is far from enough. Although the national environmental protection department and the National Standards Committee have issued more stringent environmental protection standards, the technical requirements for the certification of adhesive environmental labeling products HJ / T 220-2005, the focus is on stricter limits for triphenyl, halogenated hydrocarbons, acetone, etc., for example: pure benzene ≤ 0.2%, toluene + xylene ≤ 0.2%, halogenated hydrocarbons ≤ 0.2%, acetone ≤0.75‰, heavy metals (lead, cadmium, mercury, chromium) ≤0.5‰, etc., but the emission of high VOC is still uncontrollable, and Western developed countries such as Europe, America and Japan require high standards for environmental protection in many fields. The product is solvent-free, completely water-based, and has zero VOC emissions
