Abstract
The invention provides a method for producing an antistatic age-proof plastic housing. The method comprises the following steps: uniformly mixing methylsilicone oil, zinc stearate, a coupling agent, mineral fiber, nano silica, N-N-phenyl p-phenylenediamine, titanium tetrachloride, and diiso-octyl phosphate magnesium stearate to obtain a mixture A; uniformly mixing the other raw materials, and adding the mixture A to obtain a mixture B; placing the mixture B in a double screw extruder for melt blending, extrusion, cooling, granulation, and drying to obtain a master batch; performing fusion, injection moulding, and cooling moulding on the above master batch to obtain the antistatic age-proof plastic housing. The usage of the plastic housing is safe, the antistatic age-proof plastic housing has strong antistatic effect, reduces the harm of static on electronic products, and is suitable for producing the housing of various electronic products, aging resistance is good, problems of easy aging and easy cracking of the plastic housing materials can be solved, service life is prolonged, and insulating properties are good.
Description
technical field [0001] The invention relates to a manufacturing method of a plastic casing, in particular to a manufacturing method of an antistatic and antiaging plastic casing. Background technique [0002] With the development of science and technology, people's lives are becoming more and more convenient. With the emergence of various consumer electronic products, industrial control equipment electronic products and automotive electronic products, people have been in contact with these electronic products for a longer and longer time. More and more attention is paid to the safety and performance of use. Plastic materials are widely used in many parts of electronic products due to their light weight, corrosion resistance, easy processing, easy painting and coloring, and good insulation properties. At present, there are more and more products that use plastic materials instead of metal materials as shell materials. However, in actual use, the plastic shell materials of t...
