Nail-free all-purpose adhesive and preparation method thereof

Abstract

The invention discloses a nail-free all-purpose adhesive and a preparation method thereof, and aims to provide a nail-free all-purpose adhesive which has the advantages of high viscosity, high safety and environment friendliness and is convenient to use. The technical scheme is as follows: the nail-free all-purpose adhesive is composed of 50-100 parts of rubber SBSYH-792, 20-50 parts of rubber SBSYH-796, 20 parts of rubber LGSBS411, 5 parts of polar EVA (ethylene-vinyl acetate), 170 parts of methyl acetate, 350-445 parts of ExxsoL DSP, 30-50 parts of dichloromethane, 40-90 parts of cold-polymerized C9 petroleum resin, 20-50 parts of hot-polymerized C9 petroleum resin, 10 parts of p-tert-butyl phenol formaldehyde resin, 4 parts of active magnesium oxide, 0.125 part of water, 90 parts of terpene resin, 35 parts of modified rosin resin, 5 parts of vinyl chloride-vinyl acetate resin, 5 parts of antioxidant, 15-20 parts of vapor-phase silicon dioxide, 5 parts of titanium white, 0.5 part of coupling agent, 40-50 parts of modified bentonite and 5 parts of zinc stearate. The nail-free all-purpose adhesive belongs to the technical field of high polymers.

Description

technical field [0001] The invention relates to a universal glue, in particular to a nail-free universal glue, which belongs to the technical field of polymers. Background technique [0002] Universal glue is a commonly used adhesive, which is widely used in many fields such as home decoration, furniture manufacturing, car manufacturing, leather product production, etc. It is mainly used for bonding different materials. [0003] The first-generation neoprene special-effect glue used in traditional decoration contains toxic solvents such as toluene, which pollutes the environment and endangers human health. As people's environmental protection requirements become increasingly stringent, its market will gradually shrink. In addition, as the price of international crude oil continues to rise in recent years, the cost of chloroprene special-effect universal glue is also getting higher and higher. In order to control costs, some manufacturers use bad methods such as reducing the ...

Problems solved by technology

[0003] The first-generation chloroprene special-effect universal glue used in traditional decoration contains toxic solvents such as toluene, which pollutes the environment and endangers human health. Therefore, as people's environmental protection requirements become increasingly stringent, its market will gradually shrink.

In addition, as the price of international crude oil continues to rise in recent years, the cost of chloroprene special-effect universal glue is also getting higher and higher. In order to control costs, some manufacturers use bad methods such as reducing the solid content of glue, resulting in many unnecessary resources. Waste, also triggered vicious price competition in the neoprene market

[0004] The second generation of sbs universal adhesive, thermoplastic rubber SBS, resin, solvent oil, dimethyl carbonate as the main raw materials, poor weather resistance, not resistant to aging and easy to powder, low viscosity, inconvenient to use

Older super glues do not bond perfectly to polar surfaces and sometimes fail to bond
