Preparation method of environment-friendly flame-retardant case for computer

Abstract

The invention discloses an environment-friendly flame-retardant case for a computer and a preparation method thereof. The case is prepared from the following raw materials in parts by weight: 10 to 15parts of carbon fiber, 20 to 40 parts of EVA resin, 6 to 10 parts of aluminum hydroxide, 6 to 10 parts of magnesium hydrate, 3 to 5 parts of nylon particles, 1 to 3 parts of zinc hydroxystannate, 3 to 5 parts of ammonium phosphate, 6 to 10 parts of montmorillonoid and 1 to 2 parts of plasticizers. The environment-friendly flame-retardant case for the computer is strictly controlled; the production process parameters and the proportion of all ingredients of the computer case are strictly controlled; the nylon particles and ammonium phosphate particles are added into the raw materials; the heatrelease rate is reduced, so that the original ignition time is prolonged; the zinc hydroxystannate is added into the machine materials, so that the flame retardant and smoke suppression performance of the material can be obviously improved; the montmorillonoid material is added, so that the tensile strength and the flame retardant performance of the material are improved; the environment-friendlyflame-retardant case is suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to a method for preparing an environment-friendly flame-retardant casing of a computer. Background technique [0002] Computer hardware refers to the general term for various physical devices composed of electronic, mechanical and optoelectronic components in a computer system. These physical devices form an organic whole according to the requirements of the system structure to provide a material basis for the operation of computer software. In short, the function of computer hardware is to input and store programs and data, and to execute programs to process data into a usable form. When the user needs it, the data is output in the manner required by the user. From the appearance point of view, the microcomputer is composed of the main chassis and external equipment. The main box mainly includes CPU, memory, main board, hard disk drive, optical drive, various expansion...

AI Technical Summary

Problems solved by technology

[0003] As a commonly used hardware installation and protection structure for computers, computer casings have poor flame retardant effects, and are prone to smoke and dust during combustion, and have low tensile strength, so they are not suitable for popularization and use.
