Host shell material for computer and preparation method thereof

Abstract

The invention discloses a host shell material for a computer, which is prepared from the following components in percentage by mass: 40 to 50 percent of diatomite, 15 to 20 percent of butyronitrile styrene copolymer, 5 to 10 percent of graphene, 2 to 5 percent of glass fiber, 2 to 5 percent of coupling agent, 10 to 20 percent of calcium fluoride, 3 to 8 percent of rose powder and 2 to 5 percent ofcross-linking agent, totaling 100 percent. The host material is prepared by the following steps: uniformly mixing and stirring diatomite, calcium fluoride, a butyronitrile-styrene copolymer, a cross-linking agent, a coupling agent and graphene, and drying in a drying oven, sieving the rose powder with a 5-10-mesh sieve, uniformly mixing the sieved rose powder with glass fibers, and mixing the obtained mixture in an internal mixer, and granulating and drying the obtained mixture, adding into an injection molding machine, and molding to obtain the finished product. The mainboard provided by theinvention has good thermal conductivity, is not easy to be stained with dust, has good mechanical resistance, is simple in preparation method, and can be produced on a large scale.

Description

technical field [0001] The invention belongs to the field of computer materials, and in particular relates to a host shell material used for computers, and also relates to a preparation method of the host material. Background technique [0002] With the popularity of computers, computers have become a regular daily necessities for every household. Whether it is study, work or life, the host computer is indispensable as an auxiliary tool for the computer. The host computer is used as a shell to protect the computer hardware. Power supply and other components, at present, most of the existing host materials are resin materials, and the resin material is relatively light, which is conducive to reducing the weight of the host and internal components, but sometimes it is necessary to move and move the dosage form of the host, and the resin material appears at this time. It is a bit brittle, and the host computer is particularly serious in dust stains when it is placed away from p...

[0002] With the popularity of computers, computers have become a regular daily necessities for every household. Whether it is study, work or life, the host computer is indispensable as an auxiliary tool for the computer. The host computer is used as a shell to protect the computer hardware. Power supply and other components, at present, most of the existing host materials are resin materials, and the resin material is relatively light, which is conducive to reducing the weight of the host and internal components, but sometimes it is necessary to move and move the dosage form of the host, and the resin material appears at this time. It is a bit brittle, and the host computer is placed far away from people, and it is particularly serious to be stained with dust, and once the computer is used for a long time, its heat will be serious. At this time, a host material with good thermal conductivity, good toughness, and strong rigidity is needed.
