Abstract
The invention discloses a kind of moulding process of plastic material, step is as follows: 1) prepare burden: be 100 parts by polystyrene resin, thermo-stabilizer 4-5 part, properties-correcting agent 5-10 part, polyphosphoric acid triphenylmethyl methacrylate 0.5 part, titanium dioxide 7-9 part, moisten smart agent O.5-1 part, inorganic fillings 10-30 part; 2) mix and blend: dropped in stirrer by above-mentioned each raw material, temperature controls at 100-120 DEG C; 3) granulation: by above-mentioned stirring material in the following temperature of thermolysis point, then melt back; 4) shaping: shaping in a mold, temperature controls at about 180-200 DEG C.The hard density of plastic material applying manufacture technics of the present invention is high, and strong shock resistance, good toughness, surface-brightening are as mirror, and lines is not naturally graceful, colour-fast, not delustering, aging.
Description
Technical field
The present invention relates to a kind of polymeric material field, specifically a kind of moulding process of plastic material.
Background technology
Plastic extruding forming process allocation material of the prior art, stirring, granulation, shaping.Formula in proportioning process wherein selects resin, softening agent, thermo-stabilizer, lubricant, stopping composition and other auxiliary agents.Softening agent, due to more soft, easily makes product in fusion process, affect its banburying, after shaping, because the continuous volatilization of softening agent can impel product accelerated deterioration.Even if plastic prod takes secondary processing to improve surface smoothness, also can only be japanning glazing, because the major ingredient of pool paint is resin, again containing rare Chinese catalpa agent of volatility extra-heavy, be easy to fade, delustering.Product color is dull, matt, secondary processing cost is higher, effect is also poor.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of moulding process of novel plastic material.
Technical scheme of the present invention is achieved in that a kind of moulding process of plastic material, and step is as follows:
1) prepare burden: be 100 parts by polystyrene resin, thermo-stabilizer 4-5 part, properties-correcting agent 5-10 part, polyphosphoric acid triphenylmethyl methacrylate 0.5 part, titanium dioxide 7-9 part, moistens smart agent O.5-1 part, inorganic fillings 10-30 part;
2) mix and blend: dropped in stirrer by above-mentioned each raw material, temperature controls at 100-120 DEG C;
3) granulation: by above-mentioned stirring material in the following temperature of thermolysis point, then melt back;
4) shaping: shaping in a mold, temperature controls at about 180-200 DEG C.
The polystyrene resin that consists of of described step 1) raw material is 100 parts, thermo-stabilizer 4 parts, properties-correcting agent 5 parts, polyphosphoric acid triphenylmethyl methacrylate 0.5 part, and titanium dioxide 8 parts, moistens smart agent O.5 part, inorganic fillings 15 parts.
In described step 3) granulation process, the time of each granulation material when ultimate temperature is in 2-4 second.
The invention has the beneficial effects as follows: the hard density of plastic material applying manufacture technics of the present invention is high, strong shock resistance, good toughness, surface-brightening are as mirror, and lines is not naturally graceful, colour-fast, not delustering, aging.
