Problems solved by technology

However, the effect of the UV absorber added in this simple blending method is not good. Due to the existence of phase separation, there is a big problem in compatibility, and the UV absorber will slowly polymerize after a long time precipitated in the substance, causing the instability of the system

Abstract

TPV (Thermoplastic Vulcanizate) used in an automobile antenna material is prepared by conducting dynamic vulcanization on a vulcanization mixture. The vulcanization mixture at least comprises the following raw materials in parts by weight: 0.1 to 3 parts of grafted thermoplastic polymer, 100 parts of vulcanizable elastomer, 50 to 200 parts of thermoplastic polyolefin, 0.01 to 10 parts of a cross-linking agent, and 10 to 100 parts of filling oil, wherein the grafted thermoplastic polymer is obtained by modifying a diarylethene compound. The invention relates to the field of TPV, in particular to the TPV used in the automobile antenna material and a preparation method of the TPV.

Description

technical field [0001] The invention relates to the field of thermoplastic vulcanizate (TPV), in particular to TPV for automotive antenna materials and a preparation method thereof. Background technique [0002] TPV (thermoplastic vulcanizate) is a new green chemical material, which has the elasticity of rubber and the strength of engineering plastics. Compared with rubber, it has better processing performance and longer service life; compared with engineering plastics, it also has High strength, better flexibility and dynamic mechanical properties. The processing of traditional rubber materials consumes a lot of energy and cannot be recycled. TPV materials do not require two energy-intensive processes of mixing and vulcanization, and can be directly heated and formed to manufacture rubber products. TPV material has high plasticity and elasticity, and can be processed, used and recycled repeatedly. [0003] The automobile industry and machinery industry are the pillar ind...
