Problems solved by technology

However, this adhesive has adopted high molecular weight, high viscosity nitrile rubber and chloroprene rubber, and the obtained adhesive has a high apparent viscosity, which can only be used for hand coating, and is not suitable for machine spraying; and, due to the addition of solid Malone resin leads to poor aging resistance of the adhesive, and vehicle interior materials require high aging resistance and good long-term performance, so this type of adhesive is not suitable for use in vehicles

Embodiment Construction

[0024] The vehicle interior material spray type chloroprene-nitrile adhesive of the present invention is to be with chloroprene rubber and nitrile rubber, tackifying resin, by weight ratio 100: 10~30: 20~60 blending, and add magnesium oxide, oxidation Zinc, formed by reacting at 20-60°C.

[0025] The raw materials used in the present invention have:

[0026] Neoprene: Highly crystalline non-sulfur-adjusted neoprene, fast crystallization bonding type, with strong initial adhesion; you can directly choose neoprene with a Mooney viscosity of 17-23, or choose a Mooney viscosity of 60-60. 80 chloroprene rubber (when in use, its molecular weight needs to be reduced through rubber mixing, so that its Mooney viscosity is reduced by about 10% on the original basis, generally 20-50). In the present invention, the Mooney viscosity of chloroprene rubber is reduced by mastication or high-speed dispersion; mastication is to thinly pass the rubber on the rubber mixer, and the roller distanc...

Abstract

The invention relates to chlorobutyl-butyronitrile glue-spraying adhesive for an inside decorative material for a vehicle and a preparation method thereof. The preparation method comprises the following steps: blending neoprene rubber of which Mooney Viscosity is 17 to 50, liquid butyronitrile rubber and viscosity increasing resin in a weight ratio of 100:10-30:20-60, adding magnesium oxide, zinc oxide and antioxidant into the mixture, and reacting the mixture in a mixed solvent at the temperature of between 20 and 60 DEG C to form the adhesive, wherein the neoprene rubber of which Mooney Viscosity is 17 to 50 is obtained through rubber mixing or high-speed dispersion. The adhesive can be dried and cured after 10 to 15 minutes at normal temperature, has the advantages of good adhesive film toughness, high adhesive strength, water resistance, good heat ageing resistance and strong universality, and is suitable for adhering the inside decorative materials for vehicles such as trains, automobiles, ships and the like.

Description

technical field [0001] The invention relates to a neoprene adhesive, in particular to a neoprene-butyronitrile adhesive sprayed for vehicle interior materials, which is suitable for combining floor cloth, carpet, cold-proof materials, decorative materials, etc. with vehicle main materials such as aluminum, steel etc. bonded together. Background technique [0002] In recent years, with the rapid development of high-speed trains, automobiles, and shipbuilding industries, there are gaps and deficiencies in domestic supporting materials such as interior decoration adhesives. For example, most of the interior adhesives for high-speed trains rely on imports. At present, the interior materials of imported vehicles are mainly made of nitrile rubber. , chloroprene rubber, or two-component polyurethane, etc. are made into adhesives to spray or brush different materials respectively. China's high-speed trains and EMUs currently use Japanese NOGAWA CHEMICAL CO.LTD series products. The ...
