Abstract

The invention discloses a thermoplastic elastomer for ABS jetting adhesion, which comprises the following raw materials in percentage by weight: 10 to 80 percent of thermoplastic matrix resin, 0 to 60 percent of filling oil, 0 to 30 percent of adhesives, 0 to 30 percent of mineral filler, 0 to 10 percent of polar compatibilizer, 0.1 to 2 percent of processing aid and 0.08 to 2 percent of stabilizer. The problem of bonding non-polar base material and ABS is solved by improving a blending formulation and process. The hardness of the jetting adhesion ABS thermoplastic elastomer can be freely adjusted through the formulation so as to obtain the thermoplastic elastomer with high elasticity, high bonding strength to ABS material and good surface effect.

Description

technology field. [0001] The invention relates to the field of polymer materials, in particular to a thermoplastic elastomer used for injection bonding with ABS. Background technique [0002] ABS (that is, acrylonitrile-butadiene-styrene copolymer) resin has excellent properties such as impact resistance, high rigidity, oil resistance, low temperature resistance, good dimensional stability, and small molding shrinkage. It is a thermoplastic with a wide range of uses. . However, the surface of products made of ABS resin is often hard and smooth, and lacks texture and feel in some product applications. Therefore, a layer of soft glue is often coated on the surface of ABS finished products to enhance the texture and feel of the device. Usually the industry adopts the method of sticking a layer of thermoplastic elastomer on the surface of ABS products to achieve. Injection-bonded ABS thermoplastic elastomers are widely used in various injection molding products based on ABS, m...
