High-performance degradable computer shell and preparation method thereof

Abstract

The invention discloses a high-performance degradable computer shell which comprises the following raw materials in parts by weight: 34-40 parts of PBAT (Poly (Butyleneadipate-Co-Terephthalate)), 26-28 parts of plant powder, 28-32 parts of a modified epoxy resin, 18-22 parts of nano cellulose, 12-16 parts of rice hull ash, 8-14 parts of a polylactic acid fiber, 2-5 parts of tributyl acetate, 2-4 parts of styrene ethyl ester, 4-8 parts of an asbestos fiber and 1-3 parts of sodium potassium silicate. The invention aims to provide the high-performance degradable computer shell. The degradable computer shell is degradable, in addition is good in tension and bending strength, and has high use values and good application prospects.

Description

technical field [0001] The invention relates to the technical field of computer casings, in particular to a high-performance degradable computer casing and a preparation method thereof. Background technique [0002] A computer, commonly known as a computer, is an electronic computing machine used for high-speed calculations. It can perform numerical calculations, logic calculations, and storage and memory functions. It is a modern intelligent electronic device that can run according to programs and process massive amounts of data automatically and at high speed. , is composed of hardware system and software system. Computers without any software installed are called bare metal, which can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. More advanced computers include biological computers, Photonic computers, quantum computers, etc. With the rapid development of the electronics indust...

[0003] Although the existing computer casing has degradability, the performance such as tensile strength is not good, and it still needs to be further improved. The Chinese patent document (publication number: CN103525098B) discloses a degradable natural resin composite material suitable for the insulating casing of the metering box , is characterized in that it is composed of the following components by weight: hydrogenated rosin 32-48, polycaprolactone 28-36, plasticizer 1-4, curing agent 0.01-0.7, antistatic agent 0.5-1.6, combustion enhancer 1.0-2.7, glass microspheres 8-30, the resin composite uses more conventional raw material components, and the performance can be further improved

[0004] Chinese patent literature (publication number: CN107936564A) discloses an environmentally friendly and easily degradable plastic and its preparation method, including the following raw materials in parts by weight: 80-90 parts of epoxy modified silicone resin, 60-70 parts of polyacrylonitrile fiber , 28-32 parts of polystyrene, 26-28 parts of polyhydroxybutyrate, 24-25 parts of polylactic acid, 20-24 parts of dibutyl phthalate, 16-18 parts of activated aluminum hydroxide, stearic acid 8-10 parts of zinc, 5-8 parts of coupling agent, 4-6 parts of compatibilizer, 1-3 parts of plasticizer, and 1-2 parts of filler. For raw material mixing, and then to achieve the corresponding poor performance
