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
The present invention relates to a kind of electronic product plastic casing preparation methods.
Technical background
The technology of electronic product is maked rapid progress on the market now, and manufacturer constantly releases new product, has so just caused old constantly superseded with bad electronic product; Add that China is a consumption big country; So all can have large quantities of industrial wastes every day, and can cause certain environmental pollution, this does not meet the social theory of present environmental protection; But these industrial wastes or be difficult to recycle, or the cost that utilizes again is too high.
Summary of the invention
The present invention seeks in order to overcome the deficiency of prior art, a kind of electronic product plastic casing preparation methods that can recycle once more is provided.
The objective of the invention is to realize through following technical scheme:
A kind of electronic product plastic casing preparation methods, this method comprise the steps: by weight with 128 parts of PP; After 20 parts of oil-filled TPE, 12 parts of white oils, 36 parts of PS and 40 parts of trolamines add reaction kettle; Under protection of nitrogen gas, be heated to 230-235 ℃ and stir 3h, add 17 parts of Di Cumyl Peroxide 99s then and 24 parts of Methyl isobutyl ketones stir 4h under temperature-resistant condition; Then resultant of reaction is joined the parallel double-screw tablets press, 140～220 ℃ of plasticizings extrude pulverize particle, the particle extrusion moulding is put into tank cooling with particle, and is dry down at 80 ℃ then.
Beneficial effect of the present invention:
Material of the present invention is good in hot plastomer's mechanical property and processing characteristics, reduces production costs; Nontoxic pollution-free is applicable to scale operation, and this material can need only through cleaning, pulverize and just can carry out injection moulding as raw materials for production again in use recovery more later.
