Embodiment

[0019] The concrete preparation process of the anti-electromagnetic radiation APET film that the present invention mentions is as follows:

[0020] a) Material selection and preparation, the main components of the surface layer and their percentage ratios are: film-forming resin 45%, tourmaline powder 35%, solvent 12%, and the rest are related additives; among them, the film-forming resin is acrylic resin, electrical The average particle size of the stone powder is about 6-8um, the solvent is butyl ester, the additives include dispersant sodium pyrophosphate, coagulant hexyl silicate, antioxidant 1010, etc.; the substrate layer is made of APET sheet, and its thickness is about 0.2-0.22mm;

[0021] b) Prepare the surface coating, the preparation process is as follows: First, add the film-forming resin, solvent and antioxidant in the additive to the mixing tank, and stir thoroughly for 10-12 minutes; then, add tourmaline powder and the dispersion in the additive agent, fully st...

Abstract

The invention discloses an electromagnetic radiation resistant APET rubber piece. The APET rubber piece comprises a surface layer and a base material layer, wherein the surface layer is mainly composed of film forming resin, a tourmaline powder material, solvents and relevant auxiliaries, the base material layer is made of an APET sheet material, and the surface layer is formed on the base material layer through a spraying process. The APET rubber piece is reasonable in structural design and high in interlayer bonding strength and has unique efficacy. As the surface of the APET rubber piece contains electromagnetic radiation resistant micro-powder, the APET rubber piece has an electromagnetic radiation resistant function when used as an external package of an electronic product, and the usability of the APET rubber piece is effectively improved.

Description

technical field [0001] The invention relates to an APET film, in particular to an APET film with anti-electromagnetic radiation effect, and belongs to the technical field of APET products. Background technique [0002] APET film is a polyester sheet of plastic-absorbing material, also known as polyester hard tape. It belongs to thermoplastic environmental protection plastic products. Its side materials and waste products can be recycled. Degradable plastic. When packaged products made of this material are discarded, they end up as water and carbon dioxide. APET environmental protection film is widely used in the packaging of cosmetics, food, electronics, toys, printing and other industries, such as various high-end blister packaging, folding boxes, rubber tubes, windows, etc. At this stage, China already has relatively mature APET production technology, and its price is far lower than that of PETG sheet. [0003] APET film has excellent and stable physical properties, goo...
