Problems solved by technology

[0002] Nowadays, the technology of electronic products on the market is changing with each passing day, and manufacturers continue to introduce new products, which has caused the continuous elimination of old and bad electronic products. In addition, my country is a big consumer country, so there will be a large amount of industrial waste every day, and It will also cause certain environmental pollution, which is not in line with the current social concept of green environmental protection, but these industrial wastes are either difficult to recycle, or the cost of reusing is too high

Abstract

The invention discloses a preparation method for an electronic product plastic shell material. The preparation method comprises the following steps: after 128 parts of PP (propene polymer), 20 parts of oil-filled TPE (thermoplastic elastomer), 12 parts of white oil, 36 parts of polystyrene and 40 parts of triethanolamine are added into a reaction kettle according to parts by weight, heating to 230-235DEG C under the protection of nitrogen, and stirring for 3h; adding 17 parts of dicumyl peroxide and 24 parts of methyl isopropyl ketone, and stirring for 4h under the condition of constant temperature; then, adding reaction resultant into a parallel double-screw granulator; at the temperature of 140-220 DEG C, plasticizing, extruding and smashing to obtain particles; extruding and shaping the particles; putting the particles into a water tank to be cooled; and drying at the temperature of 80 DEG C. The material disclosed by the invention has excellent thermoplastic body mechanical property and machining performance, and the production cost is lowered; the material is nontoxic and pollution-free, and is suitable for mass production; and the material can be recovered after being used, and can be used as a production raw material for injection molding after being cleaned and smashed.

Description

technical field [0001] The invention relates to a preparation method of a plastic casing material of an electronic product. technical background [0002] Nowadays, the technology of electronic products on the market is changing with each passing day, and manufacturers continue to introduce new products, which has caused the continuous elimination of old and bad electronic products. In addition, my country is a big consumer country, so there will be a large amount of industrial waste every day, and It will also cause certain environmental pollution, which is not in line with the current social concept of green and environmental protection, but these industrial wastes are either difficult to recycle, or the cost of reusing is too high. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a method for preparing plastic casing materials of electronic products that can be recycled again. [0004] T...
