Problems solved by technology

[0003] Nowadays, when preparing mobile phone cover plates, continuous glass fiber cloth is generally used as a reinforcement layer, and epoxy resin glue is coated on both sides of it. After curing, multi-layer hot pressing is obtained to obtain glass fiber laminated boards. In practical applications, We have high requirements on the light transmittance, waterproof and moisture-proof performance of the cover plate, and we need to ensure the strength of the cover plate, but the performance of the existing glass fiber laminates is poor and cannot meet our needs

Abstract

The invention discloses a transparent glass fiber mobile phone cover plate and a preparation method thereof. During preparation, continuous glass fiber cloth is used as a reinforcing layer, two sides of the glass fiber cloth are coated with resin glue liquid, prepreg is prepared after curing, multiple layers of prepreg are compounded through hot pressing, cutting and shaping are performed, and the cover plate is obtained. The cover plate has excellent mechanical properties and water resistance, has excellent overall light transmission, and can be used as a mobile phone cover plate. The process design is reasonable, the component proportion is proper, and the prepared mobile phone cover plate not only has high-strength mechanical properties, but also has excellent surface water resistance, low water absorption and good light transmission, can be widely applied to the fields of mobile phone cover plates, electronic product cover plates, shells and the like, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of glass fiber cover plates, in particular to a transparent glass fiber mobile phone cover plate and a preparation method thereof. Background technique [0002] Glass fiber (formerly known as: glass fiber) is an inorganic non-metallic material with excellent performance. Wear resistance is poor. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy. [0003] Nowadays, in the preparation of mobile phone cover plates, continuous glass fiber cloth is generally used as a reinforcement layer, and epoxy resin glue is coated on both sides of it. After curing, multi-layer hot pressing is performed to obtain a glass fiber laminate. We have high requirements for the light transmittance, waterproof and moisture-proof performance of the cover plate, and we need to ensur...
