Abstract

The invention discloses a heat dissipation plastic for a mobile phone shell. The heat dissipation plastic comprises the following raw materials in parts by weight: 60 to 100 parts of thermoplastic polyurethane elastomer, 10 to 20 parts of pyrolusite, 4 to 8 parts of nanometer boron fiber, 4 to 6 parts of copper powder, 3 to 6 parts of aluminum powder, 3 to 6 parts of mullite, 2 to 5 parts of monopotassium phosphate, 2 to 4 parts of zinc carbonate, 4 to 8 parts of rice husk carbon dust, 3 to 6 parts of pantothenic acid, 2 to 5 parts of borax, 1 to 3 parts of diatomite, and 1 to 2 parts of methyl dihydrojasmonate. The heat dissipation plastic has excellent comprehensive properties, is beneficial to the protection for mobile phones, good in heat dissipation effect, and beneficial to heat dissipation of mobile phones; the preparation material is available, the preparation method is simple, the plastic is beneficial to industrial production, and has good economic value and market value.

Description

technical field [0001] The invention relates to a plastic, in particular to a heat-dissipating plastic for a mobile phone case and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the industry of technology beauty has emerged as a new industry. Fashion IT brands develop with the diversification of the market. According to the increase of mobile phone brands and functions, the mobile phone protective case is divided into PC case, leather, silicone, cloth, hard plastic, leather case, metal tempered glass case, soft plastic, velvet, silk and other categories. . Silicone case is the most well-known type of mobile phone protective case. It has a soft texture and a slightly slippery feel and has been popular in the market for many years. The phone case is not only an ornament to make your phone a landscape, but also protects your phone from being dropped, scratched, waterproof and shockproof. At present, some mob...
