Abstract

The invention discloses a high-transparency PC product and a preparation method thereof. The high-transparency PC product is characterized by comprising the following raw materials in parts by weight:40-60 parts of a resin base material, 6-12 parts of polymethyl methacrylate, 4-8 parts of polycarbonate diol, 5-8 parts of an antioxidant, 8-15 parts of nano silicon dioxide, 5-8 parts of a transparent toughening agent and 0.5-2 part of a compatilizer. The high-transparency PC product provided by the invention overcomes the defects of no scratch resistance, low transparency and non-uniform thickness, solves the two problems at the same time, has excellent properties of high hardness and high toughness, and also has good surface gloss and good UV aging resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a highly transparent PC product and a preparation method thereof. Background technique [0002] Engineering material products occupy a very important position in people's daily life and industrial and agricultural production. With the wide popularization and application of engineering material products in the field of daily use, people come into contact with and use more frequently such as plastic products, so the requirements for the products are getting higher and higher. In particular, polycarbonate resin has excellent transparency, heat resistance, and mechanical properties, and has various excellent characteristics such as high dimensional accuracy. As a glass-like product, it has high transparency, unbreakability, and high toughness comparable to glass. It is used as the main material to replace glass, and is used for water cups, storage tanks and oth...
