Abstract
The invention discloses a molding process of a plastic sectional material. The process comprises the following steps: 1) preparing materials: 100 parts of polystyrene resin, 4-5 parts of thermal stabilizing agent, 5-10 parts of modifier, 0.5 part of triphenyl polyphosphate, 7-9 parts of titanium white, 0.5-1 part of fine lubricating agent and 10-30 parts of inorganic filling material; 2) mixing and stirring: putting all the raw materials in a blender and stirring at the temperature of 100-120 DEG C; 3) pelleting: repeatedly smelting the mixed material at the temperature below a thermal decomposition point; and 4) molding: molding in a mould at the temperature of about 180-200 DEG C. The plastic sectional material manufactured by applying the process provided by the invention has high hard density, strong impact resistance, good toughness, bright surface like a mirror, natural and elegant lines, fastness, no deading and no ageing.
Description
Technical field
The present invention relates to a kind of polymeric material field, specifically is a kind of moulding process of plastic material.
Background technology
Plastic extruding forming process allocation material of the prior art, stirring, granulation, moulding.Prescription in the proportioning process is wherein selected resin, softening agent, thermo-stabilizer, lubricant, stopping composition and other auxiliary agents for use.Softening agent is prone to make product in fusion process, to influence its banburying because soft, after the moulding, because of the continuous volatilization of softening agent can impel the product accelerated deterioration.Even if plastic prod takes secondary processing to improve surface smoothness, also can only be the japanning glazing, because the major ingredient of pool lacquer is a resin, contain rare Chinese catalpa agent of volatility extra-heavy again, 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 defective, the present 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 following:
1) batching: with polystyrene resin is 100 parts, thermo-stabilizer 4-5 part, and properties-correcting agent 5-10 part, 0.5 part of polyphosphoric acid triphenylmethyl methacrylate, white titanium pigment 7-9 part is moistened O.5-1 part of smart agent, inorganic fillings 10-30 part;
2) mix stirring: above-mentioned each raw material is dropped in stirrer, and temperature is controlled at 100-120 ℃;
3) granulation: above-mentioned stirring material is put following temperature, melt back then in thermolysis;
4) moulding: in die for molding, temperature is controlled at about 180-200 ℃.
The polystyrene resin that consists of of said step 1) raw material is 100 parts, 4 parts of thermo-stabilizers, and 5 parts of properties-correcting agent, 0.5 part of polyphosphoric acid triphenylmethyl methacrylate, 8 parts of white titanium pigments moisten O.5 part of smart agent, 15 parts of inorganic fillings.
In the said step 3) granulation process, the each time of granulation material when ultimate temperature is in 2-4 second.
The invention has the beneficial effects as follows: use the hard density height of plastic material that technology of the present invention is made, strong shock resistance, good toughness, surface-brightening such as mirror, lines are graceful, colour-fast naturally, not delustering, aging.
