Abstract

The invention discloses a high-flow super-tough cold-resistant material specially used for shells of PC electronic products. The material comprises the following raw materials: a PC resin, a flexibilizer, a functional aid, a compatilizer, an anti-oxidant and a processing aid. The invention further discloses a preparation method for the material specially used for the shells. According to the invention, physical and mechanical properties of the material can be substantially improved; the flexibilizer has excellent low temperature impact performance, improves low temperature impact strength of the material and enables the material to have good toughness at a low temperature of -40 DEG C; the functional aid has good fluidity and chemical resistance and can improve fluidity and chemical resistance of the material; the preparation method provided by the invention can rapidly prepare the special material with good fluidity, ultrahigh toughness, cold resistance and chemical solvent resistance, the material can be extensively used in the field of electric products like thin-wall shells of mobile phones and shells of earphones, and the preparation method has simple procedures and is easy to realize.

Description

technical field [0001] The invention relates to the technical field of housing materials for electronic products, in particular to a special high-flow super-tough and cold-resistant PC electronic product housing material and a preparation method thereof. Background technique [0002] A mobile phone, commonly referred to as a mobile phone, and commonly known as "Big Brother" in the early days, is a portable phone terminal that can be used in a wide range. [0003] As an important communication tool, mobile phone has become more and more popular in people's daily life, and the mobile phone market also has great potential. [0004] With the development of the mobile phone market, there are many kinds of mobile phones sold on the market, each of which has different design concepts, and strives to meet the requirements of different users. Although these mobile phones can roughly meet the requirements of use, their mobile phone casings are made of ordinary PC materials, and the ...
