Abstract

The invention relates to the technical field of plastics, in particular to a high-temperature-resistant plastic piece and a preparation method thereof, wherein the high-temperature-resistant plastic piece is prepared from the following components in parts by mass: 5-8 parts of mica, 4-6 parts of a silane coupling agent, 2-5 parts of an antioxidant, 1-4 parts of a plasticizer, 15-30 parts of a low-density polyethylene resin, 40-45 parts of a high-density polyethylene resin, 8-15 parts of a vinyl chloride polymer and 8-10 parts of an amino-terminated polymer A. The high-temperature-resistant plastic disclosed by the invention is reasonable in formula design, can effectively improve the stability of the plastic at high temperature, avoids the conditions of softening, bending, deformation and the like, and improves the use performance.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a high-temperature-resistant plastic part and a preparation method thereof. Background technique [0002] In the prior art, there are high requirements for the use environment of plastics. When working at high temperatures, the plastics are easy to soften, which affects the strength and toughness they should have. However, when working at low temperatures, the toughness of plastics will also drop instantly, which seriously affects the strength and toughness of plastics. normal performance. [0003] The following problems exist: [0004] 1. At higher temperatures, plastics are prone to bending and deformation; [0005] 2. When working at low temperature, the toughness of the plastic will decrease, making it brittle and easy to break. Contents of the invention [0006] Aiming at the deficiencies of the prior art, a high-temperature-resistant plastic with stable performance un...
