Problems solved by technology

However, in conventional glass fiber-reinforced PC materials, glass fiber can impart strong rigidity to the material, but the toughness of the material is greatly damaged; due to the high surface tension of the PC material, dirt is easy to adhere to the surface of the material
[0004] At present, fibrous fillers are mainly used for reinforcement in the system. The addition of fibrous fillers will greatly reduce the toughness of the material, and the balance of rigidity and toughness cannot be achieved; at the same time, the addition of general fibrous fillers usually increases the surface energy of the material. Reduced stain resistance of the material

Abstract

The invention provides a polycarbonate composition and a preparation method thereof, wherein the polycarbonate composition comprises the following components in parts by weight: 50-90 parts of polycarbonate, 5-90 parts of fibrous filler treated with acetone 50 parts, 0.1-3 parts of silicone oil dispersant, 0.05-0.2 part of lubricant, 0.01-10 parts of other additives; the bisphenol A content contained in the polycarbonate is between 0-50ppm, and the hydroxyl content is 20 ‑300ppm; the lubricant is one of oxidized polyethylene wax lubricants, ethylene acrylic acid copolymer lubricants, polyethylene wax lubricants, and high acid value polyethylene wax lubricants. In the polycarbonate composition of the present invention, the fibrous filler treated with acetone, the silicone oil dispersant and the lubricant are synergistic and practical, which can reduce the surface energy of the material and improve the toughness of the material.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, in particular to a polycarbonate composition and a preparation method thereof. Background technique [0002] Polycarbonate PC is one of the five major engineering plastics. It has high impact resistance and heat resistance, and is widely used in all aspects of people's production and life. However, due to some defects of polycarbonate, such as poor processing performance, easy stress cracking, sensitive notch resistance, and poor wear resistance, it cannot meet the needs of actual use in some occasions, so people began to use glass fiber for polycarbonate. Esters are enhanced. [0003] Glass-reinforced PC materials are widely used in the fields of automobiles, electronic appliances, and home appliance materials due to their good strength, toughness, and thermal properties. However, in conventional glass fiber-reinforced PC materials, glass fiber can give the material strong rigidit...
