Abstract

The invention discloses corrosion-resistant plastic and a preparation method thereof. The corrosion-resistant plastic is prepared from the following raw materials in parts by weight: 80-100 parts of polyvinyl chloride, 5-8 parts of corrosion-resistant filler, 1-3 parts of a dispersing agent, 3-5 parts of a plasticizer and 3-5 parts of a heat stabilizer. The corrosion-resistant filler has a very good corrosion-resistant effect, and the heat stabilizer is prepared through the following steps: taking methyltrimethoxysilane and dimethyldimethoxysilane as raw materials, preparing organic silicon resin through reaction, reducing p-nitrobenzaldehyde by iron powder, reducing nitryl into amino, preparing an intermediate 1, enabling the intermediate 1 to react with phosgene, and preparing an intermediate 2; enabling the intermediate 2 and the 6-amino-1, 3-dimethyl uracil to react to prepare an intermediate 3, and enabling the isocyanate group on the intermediate 3 and the hydroxyl group on the organic silicon resin to react to prepare the thermal stabilizer, such that the thermal stability of the plastic can be improved so as to prolong the service life of the plastic;.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a corrosion-resistant plastic and a preparation method thereof. Background technique [0002] Plastic is a class of plastic synthetic polymer materials. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials that are indispensable in today's daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure, and maintains the same shape at room temperature. [0003] Existing plastics will not corrode in a short period of time after being exposed to corrosive substances during use, but after long-term contact, the performance of the plastic will decline, and at the same time, its performance will be greatly reduced when used in a high temperature environment, making ...
