Abstract

The invention discloses a heat dissipation protective sleeve and a method for preparing the same. The method includes steps of uniformly mixing and smashing heat conduction materials, infrared radiation materials and auxiliaries with one another to obtain powder; adding the powder into shell molding materials and uniformly mixing the powder and the shell molding materials with one another to obtain homogenous materials; carrying out injection molding on the homogenous materials to obtain the heat dissipation protective sleeve. The heat dissipation protective sleeve and the method have the advantages that the problem of poor heat dissipation functions of protective sleeves for mobile phones in the prior art can be solved by the aid of the heat dissipation protective sleeve and the method, and the heat dissipation protective sleeve further can have a negative ion release function.

Description

technical field [0001] The invention relates to the technical field of protective covers, in particular to a heat dissipation protective cover and a preparation method thereof. The heat dissipation protective cover is suitable for mobile terminals such as mobile phones and tablet computers. Background technique [0002] With the increasing frequency of use of mobile phones in modern life, the heat dissipation of mobile phones has become a prominent problem. However, the mobile phone protective cases or protective shells seen on the market do not have the heat dissipation function, and even block the effective dissipation of heat from the mobile phone, resulting in poor experience for mobile phone users, program exits or even shutdown. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the object of the present invention is to provide a heat dissipation protectiv...
