Abstract

The invention relates to the technical field of thermoplastic elastomer materials, and discloses a TPV easy for ink dyeing and printing and a preparation method of the TPV. The TPV is mainly preparedfrom polyolefin rubber, polyolefin resin, white oil, maleic anhydride graft modified polyolefin resin, an ethylene-vinyl acetate copolymer, an ethylene-methyl acrylate copolymer, a peroxide, a crosslinking assistant, an antioxidnt, a light stabilizer and a surface modifier. The preparation method includes: firstly premixing the raw materials in a twin-screw extruder according to a certain ratio toobtain a premixed product, and adding a crosslinking agent and a crosslinking aid to vulcanize the premixed product, thereby obtaining the TPV material easy for ink dyeing and printing. The TPV material provided by the invention has the advantages of simple preparation process, good printing / dyeing properties, and strong adsorption effect on common printing ink, and has important significance inwidening the application field of thermoplastic elastomers.

Description

Technical field:

[0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a method for making TPV with easy ink printing and dyeing. Background technique:

[0002] TPV thermoplastic dynamic vulcanizate is a polymer elastomer material composed of highly vulcanized EPDM particles dispersed in continuous polypropylene PP phase. Its characteristic is that the rubber is vulcanized during the melt blending process of rubber and thermoplastics. Of course, when the rubber is vulcanized, it is also continuously mixed with thermoplastics. Therefore, the vulcanized rubber is distributed as a dispersed phase in the continuous phase of thermoplastics. It has excellent anti-aging, ozone resistance and ultraviolet resistance properties. It does not need vulcanization when used. It can be directly processed by injection, extrusion, calendering, blow molding, etc., which can shorten the processing process and reduce processing costs. It has a wide ran...
