High-strength antistatic 3D sheet and preparation method thereof

Abstract

The invention discloses a high-strength antistatic 3D sheet and a preparation method thereof. The preparation method of the 3D sheet comprises the following steps; (1) preparing a glue solution, and coating the surface of glass fiber cloth with the glue solution through an electrophoresis method to form a prepreg; (2) attaching a release film to the surface of the prepreg, slitting the prepreg into different shapes, stripping and removing the release film, and stacking the prepreg layer by layer to form a to-be-pressed prepreg; and (3) putting the prepreg to be pressed into a mold, and carrying out compression molding to obtain the high-strength antistatic 3D sheet. The glue solution comprises the following raw materials in parts by weight: 90-120 parts of resin, 24-48 parts of a curing agent, 15-17 parts of pretreated nano diamond powder, 2-5 parts of a cross-linking agent and 0.3-0.7 part of an antioxidant. The 3D sheet prepared by the invention has good mechanical strength, excellent antistatic property, heat dissipation property and heat resistance, and can be widely applied to cover plates and protective jackets of mobile phones, communication equipment and other electronic products.

Description

technical field

[0001] The invention relates to the technical field of sheet processing, in particular to a high-strength antistatic 3D sheet and a preparation method thereof. Background technique

[0002] With the advent of the Internet age, electronic products such as mobile phones and communication equipment have become indispensable tools in people's lives; especially mobile phones are communication tools that people carry with them; Pay attention to.

[0003] As the main components of the mobile phone, the mobile phone cover and protective case are also particularly important for their safety, stability and experience. The safety and stability of mobile phones, especially the requirements for electrostatic protection, are relatively high. In the relatively dry environment in autumn and winter, the human body will generate static electricity due to friction. Harmful, loss of mobile phone life, and even combustion and explosion. In terms of mobile phone use experience,...
