Problems solved by technology

On the one hand, cold-resistant plasticizers have poor compatibility with PVC materials, which leads to their ineffective effect on improving the low-temperature willfulness of PVC materials; on the other hand, these materials are volatile, which also makes PVC gradually reduce its low-temperature willfulness during use.

Abstract

The invention discloses a low-temperature and folding-resistant automotive interior material and a preparation method thereof. The material includes the following components: PVC resin powder, a modifier, a heat stabilizer, a light stabilizer, a plasticizer, an inorganic filler, a colorant, a deodorant and a fire retardant. By optimizing the composition of the material, the compatibility between the plasticizer and PVC resin is obviously improved; and during the use, volatility of the plasticizer is also significantly reduced such that the low-temperature toughness of the material is significantly improved, which meets use requirements at minus 20 DEG C.

Description

technical field [0001] The invention generally relates to the field of automobile materials, and more specifically relates to a low-temperature folding-resistant automobile interior material. Background technique [0002] Automotive interior materials are becoming more and more high-grade. Soft hand feeling and folding resistance are the basic requirements. However, the softness of ordinary PVC materials will change greatly with the change of temperature. Materials that are normally used at room temperature will harden, reduce flexibility, and reduce service life at low temperatures. The usual practice is to add plasticizers and nitrile rubber to increase the flexibility of the product, but it is still unsatisfactory in actual use. On the one hand, cold-resistant plasticizers have poor compatibility with PVC materials, which leads to their ineffective effect on improving the low-temperature willfulness of PVC materials; on the other hand, these materials are volatile, which...
