Abstract

The invention discloses a special high-glossiness modified master batch for a transparent PVC (Polyvinyl Chloride) hard product and belongs to the technical field of high molecular materials. The special high-glossiness modified master batch for the transparent PVC hard product, provided by the invention, is prepared from pre-treated PVC matrix resin, a stabilizing agent, a plasticizer, a lubricant, a de-foaming agent, a filler and modified graphene oxide, wherein the pre-treated PVC matrix resin is obtained by mixing and swelling PVC resin and a solvent, carrying out heat treatment and ageingand then freezing and crushing; the modified graphene oxide is prepared by heating graphene oxide, octadecylamine and trichloromethane and stirring and reacting; in a preparation process, the pre-treated PVC matrix resin, the stabilizing agent, the plasticizer, the lubricant, the de-foaming agent and the filler are mixed and then the modified graphene oxide is added; after the components are continually and uniformly mixed, extrusion and granulation, cooling and packaging are carried out to obtain the special high-glossiness modified master batch for the transparent PVC hard product. The special high-glossiness modified master batch for the transparent PVC hard product, disclosed by the invention, has excellent transparency, mechanical properties and light stability.

Description

technical field

[0001] The invention discloses a high-gloss modified masterbatch for transparent PVC hard products, which belongs to the technical field of polymer materials. Background technique

[0002] In the field of plastics industry, PVC has been widely used, but due to its low impact toughness, impact modifiers need to be added; in addition, the addition of inorganic nanoparticles can also play a role in toughening. Adding an impact modifier will increase the cost, and adding inorganic nanoparticles can reduce the cost, but it is not easy to disperse in the PVC matrix, so its content is limited.

[0003] As an important part of polymer mechanochemistry, polymer solid-phase mechanochemistry is mainly concerned with the process of crushing (including crushing, grinding, crushing), mechanical processing (cutting, cutting, grinding, milling), fatigue wear, and abrasion of polymer materials. The study of chemical phenomena and chemical processes in such processes. Gu...
