Material for producing mobile phone shells, and preparation method of material

Abstract

The invention discloses a material for producing mobile phone shells, and a preparation method of the material. The material is mainly prepared from the following components in parts by weight: 22-42parts of an acrylonitrile-ethylene propylene diene monomer (EPDM) rubber-styrene resin copolymer, 14-23 parts of polycarbonate, 13-26 parts of epoxy resin, 21-34 parts of nitrile rubber, 1.3-6.5 partsof glass fibers, 0.3-2.2 parts of silicon carbide whiskers, 0.5-3.8 parts of nano-titanium dioxide, 2-10 parts of a compatilizer, 0.05-2 parts of an antibacterial agent and 0.4-2 parts of a lubricating agent. The material is prepared by the steps of mixing at a high speed, extruding and granulating, and the like. The material for manufacturing the mobile phone shells is high in hardness, good inwear resistance and heat resistance, has a better antibacterial effect, and is simple in preparation technology and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of mobile phone shell materials, in particular to a material for manufacturing mobile phone shells and a preparation method thereof. Background technique [0002] As a commonly used communication tool, mobile phones have become an indispensable part of people's lives. With the popularity of smart phones, mobile phones are more and more widely used in daily life, and smart phones are highly integrated as a technology. This poses a huge challenge to the protection of mobile phones. When the mobile phone is impacted, the damage to the circuit board is particularly large. It is possible that the mobile phone may be irreparable during an inadvertent collision. Due to the advantages of low cost and other advantages, it has been widely developed in the field of mobile phone protective cases, but the existing plastic structure of mobile phone cases is low in strength, and it is prone to bending when the mobile phone...

This poses a huge challenge to the protection of mobile phones. When the mobile phone is impacted, the damage to the circuit board is particularly large. It is possible that the mobile phone may be irreparable during an inadvertent collision. Due to the advantages of low cost and other advantages, it has been widely developed in the field of mobile phone protective cases, but the existing plastic structure of mobile phone cases is low in strength, and it is prone to bending when the mobile phone is dropped or impacted, and cannot provide good protection for the internal components of the mobile phone. , and its own poor heat resistance, aging resistance, poor antibacterial properties, pressure reduction at higher temperatures, low pressure bearing capacity, and the protection of mobile phones cannot meet the needs
