Preparation process of wear-resistant antioxidant plastic

Abstract

The invention discloses a preparation process of wear-resistant antioxidant plastic. The preparation process specifically comprises the following operation steps: S1, preparing a base material A; S2,preparing a base material B; S3, preparing a base material C; S4, preparing a base material D; S5, preparing an additive; and S6: mixing. According to the antioxidant plastic prepared by the invention, the anti-ultraviolet agent is added into the base material C, so that the prepared finished product can prevent ultraviolet rays from penetrating through a polymer and can inhibit and delay photoaging of the polymer caused by the ultraviolet rays, and the defoaming agent is added into the base material C, so that the surface tension of a solution, a suspension liquid and the like is reduced, andfoam formation is prevented; or the original foam is reduced, a large amount of foam is prevented from being generated in the reaction, the antioxidant is stirred with the base material A, the base material B and the base material C, so that the prepared finished product has the function of delaying oxidation, the antioxidant can not catalyze the oxidation reaction by weakening the activity of oxidase, and the performance is prevented from being influenced by cracking of the plastic.

Description

Technical field[0001]The invention belongs to the technical field of the preparation of anti-oxidation plastics, and specifically relates to a preparation process of wear-resistant and anti-oxidation plastics.Background technique[0002]In the process of preparation, processing and application of mixed polymers and their products, structural changes will inevitably occur, which will damage the strength and appearance until they lose use value. This phenomenon becomes the oxidation of polymer materials, such as embrittlement of plastic , Rubber cracking, etc., resulting in darkening, discoloration, deformation, and even mildew on the surface of the plastic. Among the external factors, the main factors that cause plastic oxidation are light, oxygen, and heat. The auto-oxidation reaction and thermal decomposition reaction of the polymer lead to the oxidation of the polymer, which reduces the performance of the plastic and the service life of the plastic product. Therefore, it is necessar...

[0002] Mixed polymers and their products will inevitably undergo structural changes in the process of preparation, processing and application, which will damage the strength and appearance until they lose their use value. This phenomenon becomes the oxidation of polymer materials, such as the embrittlement of plastics. , rubber cracks, etc., which lead to darkening, discoloration, deformation, and even mildew on the surface of the plastic. Among the external factors, the main factors that cause the oxidation of the plastic are light, oxygen, and heat. The automatic oxidation reaction and thermal decomposition reaction of the polymer lead to the oxidation of the polymer, which reduces the performance of the plastic and greatly reduces the service life of the plastic product
