Abstract

The invention relates to a high heat-resistant elastomer mixed material and a preparation method thereof. The material is prepared from the following components in percentage by weight: 30-50% of a polypropylene copolymer PP, 30-50% of an allyl elastomer, 8-15% of a metallocene LLDPE (Linear Low-Density Polyethylene), 1-5% of a flow promoter, and 1-2% of an additive. The elastomer mixed material provided by the invention has high heat-resistant performance; a prepared rubber cushion cannot fall off in a high temperature resistance (85 DEG C) long-term test, so that the problem that the rubber cushion falls off from a PP cover plate easily at a high temperature is well solved. The elastomer mixed material is simple in formula, low in cost, and easy to operate and implement, thereby having popularization and application values.

Description

technical field [0001] The invention relates to a mixed material, in particular to a high heat-resistant elastomer mixed material and a preparation method thereof. Background technique [0002] Polypropylene (pp) is a versatile and inexpensive plastic resin with a wide variety of uses. Polyolefin elastomers have excellent properties such as aging resistance, ozone resistance, and chemical medium resistance, but their properties such as heat resistance and tensile strength are relatively low, and the cost is relatively high. In real life, this type of elastomer is used for PP The rubber pad on the cover, but due to its insufficient heat resistance, when the ambient temperature is higher than 70°C, the rubber pad will be deformed or even melted, and the rubber pad will fall off, so its application range is limited. [0003] Chinese invention patent CN 103923395B discloses a halogen-free flame-retardant heat-resistant PP plastic for automotive interior parts and its preparati...
