Abstract

The invention discloses a plastic with good thermal conductivity. The plastic is prepared from the following raw materials in parts by weight: 80 to 120 parts of polycarbonate, 30 to 50 parts of polyhexamethylene succinate, 10 to 20 parts of polyolefin elastomer, 5 to 10 parts of calcium carbonate, 8 to 16 parts of silicon carbide, 6 to 12 parts of aluminum oxide, 5 to 10 parts of graphene, 4 to 8parts of diamond micropowder, 3 to 6 parts of glass fiber, 5 to 10 parts of silane coupling agent, 30 to 50 parts of polyethylene glycol, 4 to 7 parts of 2-hydroxyl-4-methoxydiphenylketone, 2 to 5 parts of calcium stearate, and 3 to 5 parts of 2,4-dichlorobenzoyl peroxide. The invention also discloses a preparation method of the plastic with good thermal conductivity. The prepared plastic has good thermal conductivity under the cooperation function of the raw materials.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a plastic with good thermal conductivity and a preparation method thereof. Background technique [0002] Plastic is an important organic synthetic polymer material, which is widely used. In electronic products, plastic is used to make circuit boards or product casings. Compared with other materials, plastic has obvious advantages. Plastic has good toughness and strength. The quality of the product prepared from the raw material is relatively light. [0003] In electronic products, the integration of electronic circuits is getting higher and higher, and the heat generated during the operation of the chip is difficult to release. The accumulation of heat will affect the working stability of the device and shorten its life. Therefore, how to effectively and quickly dissipate heat from electronic devices becomes the key The problem. Plastic is often used to make the casing of elec...
