High-gloss PP material and preparation method thereof

Abstract

The invention discloses a high-gloss PP material which comprises the following components in percentage by mass: 45 to 50 percent of PP, 30 to 35 percent of PPB, 18 to 18.5 percent of barium sulfate, 0.3 to 0.4 percent of an aluminate coupling agent, 0.05 to 0.1 percent of an antioxidant, 0.15 to 0.2 percent of an auxiliary antioxidant, 0.05 to 0.1 percent of an anti-ultraviolet agent, 0.2 to 0.5 percent of a lubricant and 0.1 to 0.2 percent of a nucleating agent. According to the invention, the surface gloss and hardness of PP are effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of chemical material preparation, and in particular relates to a high-gloss PP material and a preparation method thereof. Background technique

[0002] Patent No. CN102816378A is a barium sulfate reinforced polypropylene sound insulation composite material. Usually, barium sulfate is added to polypropylene (PP) as a filler to change the effect of sound insulation and noise reduction on the composite material. Its surface gloss and hardness are limited and cannot Comparing with PS, ABS and other high-gloss plastics, it cannot meet the parts with higher requirements for appearance decoration.
