Problems solved by technology

[0002] Existing car floor mats generally use PVC as a raw material. Its advantages are good mechanical properties, wear resistance, and chemical corrosion resistance, but its disadvantages are poor elasticity and low temperature resistance. The material begins to change when the temperature is as low as 0 degrees. It is very hard, which brings great inconvenience to daily use
Now car mats are generally made of polyvinyl chloride, so the mats will become hard and unusable at low temperature

Abstract

The invention discloses a TPE (Thermoplastic Elastomer) low-temperature resisting foot pad and a preparation method thereof. The foot pad is prepared from 12% of SEBS, 12% of SBS (Styrene Butadiene Styrene), 12% of PS (Poly Styrene), 7% of PP (Propylene), 30-32% of naphthene white oil KN4010, 0.5% of stearic acid 401, 0.6% of zinc stearate, 0.3% of antioxidant and 23.6-25.6% of nano calcium carbonate. The preparation process comprises the following steps: firstly, stirring SEBS, SBS, PS and PP in a high-speed mixing machine, further adding nano calcium carbonate, stearic acid, zinc stearate, antioxidant and naphthene white oil, stirring, pelleting the mixed materials in a pelletizer, performing injection molding, checking whether each finished product meets the quality, packaging and warehousing qualified products. The TPE is adopted as the raw material of an automobile foot pad, the original softness can be maintained at the temperature of 0 DEG C in an automobile, and the situation that the foot pad is hardened and cannot be used any longer is prevented.

Description

technical field [0001] The invention relates to an automobile floor mat and a preparation process thereof, in particular to a TPE low temperature resistant floor mat and a preparation process thereof. Background technique [0002] Existing car floor mats generally use PVC as a raw material. Its advantages are good mechanical properties, wear resistance, and chemical corrosion resistance, but its disadvantages are poor elasticity and low temperature resistance. The material begins to change when the temperature is as low as 0 degrees. It is very hard, which brings great inconvenience to daily use. Now car mats are generally made of polyvinyl chloride, so the mats will become hard and unusable under low temperature conditions. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a TPE low-temperature-resistant mat and its preparation process. TPE (Thermoplastic Elastomer) is a rubber-like high elasticity, high streng...
