Problems solved by technology

[0003] These fall-proof protective covers are mainly made of metal, silicone and plastic. Among them, the metal material has a good protective effect, but the texture is poor and the production cost is also high.
The degree of plastic material is low and the protection is good, but it is easy to age
Silicone material has good elasticity, the best anti-drop performance, good skin-friendliness, and comfortable touch. However, the heat conduction effect of silicone material is poor. It is difficult to dissipate the heat during the use of electronic products, which may easily lead to overheating of the equipment, especially in summer. The disadvantages may even affect the normal use of electronic products

Embodiment 1

[0021] A silica gel protective cover with good thermal conductivity. According to the mass parts, the silica gel used for the protective cover is prepared from the following raw materials: 100 parts of silicone rubber, 10 parts of vinyl silicone oil, 5 parts of hydroxyl silicone oil, 0.4 parts of catalyst, polydimethyl 2 parts of siloxane, 3 parts of zinc stearate, 16 parts of aluminum oxide powder, 4 parts of copper powder, and 1 part of coupling agent.

[0022] The silicone rubber is dimethyl silicone rubber; the catalyst is a platinum complex catalyst; the mesh number of the copper powder is 200 mesh.

[0023] The alumina powder has been modified. The modification process is as follows: dissolve the silane coupling agent in the ethanol solvent, then add the alumina powder into the solution and mix evenly. Stir at a rotating speed for 15 minutes, and then dry to obtain the desired modified alumina powder, the mesh number of which is 250 mesh.

Abstract

The invention belongs to the technical field of electronic product accessories, and particularly relates to a silicone protective cover with good thermal conductivity. The silicone protective cover isprepared from silicone rubber, vinyl silicone oil, hydroxyl silicone oil, catalyst, polydimethylsiloxane, zinc stearate, alumina powder, copper powder and coupling agent. The silicone rubber is selected from one of dimethyl silicone rubber, fluorosilicone rubber and methyl phenyl vinyl silicone rubber; the catalyst is a platinum complex catalyst; alumina is modified by an ethanol solution of a silane coupling agent. The silicone protective cover has better impact resistance, excellent protection performance, comfortable touch feeling and improved thermal conductivity.

Description

technical field [0001] The invention belongs to the technical field of electronic product accessories, and in particular relates to a silica gel protective cover with good thermal conductivity. Background technique [0002] Today's electronic products such as mobile phones, tablet computers, and notebook computers are getting better and better in performance and have more and more functions. We can handle various problems such as office, entertainment, and shopping on these products. However, with the improvement of product performance, the precision of equipment parts is also increasing geometrically, so the protection requirements of these electronic products are also getting higher and higher. In order to improve the anti-drop and impact resistance, most users will equip these electronic products with protective cases or cases. [0003] These fall-proof protective covers are mainly made of metal, silicone and plastic. Among them, the metal material has a good protective ...
