Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of PP composite material and preparation method thereof.
Background technology
Polypropylene (PP) is one of kind the most rapid developed in Plastics Industry, has good mechanical property, light specific gravity, nothing
Poison, easy processing, it is corrosion-resistant the advantages that；It is cheap and raw material is easy to get, thus obtained in household electrical appliances, automobile and packaging field
It is widely applied.High glaze, high rigidity polypropylene material because its surface gloss it is good, progressively substitute price it is relatively expensive
ABS plastic, and it is widely used in the application field that had certain requirements to glossiness, heat resistance and hardness, as electric cooker, electricity are pressed
The small household appliances such as bucket, hair dryer, insulating pot, micro-wave oven, electric heater.China as current maximum small household appliances production, consumption and
Exporting country, exploitation and production high glaze, high rigidity polypropylene material tool are of great significance.
Domestic traditional high glaze, the production of high rigidity polypropylene material, the method for a large amount of content inorganic fillings of generally use, product ratio
Weight height, poor fluidity, mechanical property are low, and glossiness is also not ideal enough.
A kind of high glaze, high rigidity polypropylene material are provided, for promoting domestic relevant industries to develop, increasing economic efficiency has
Significance.
The content of the invention
It is an object of the invention to provide a kind of PP composite material, high glaze, high rigidity, low-gravity；Present invention simultaneously provides
The preparation method of PP composite material, it is scientific and reasonable, simple and easy.
PP composite material of the present invention, it is made up of the raw material of following parts by weight：
Described polypropylene is homopolymerization powdered resin.
Described polystyrene is the powder of polystyrene pellets grinding.
Described filler be barium sulfate, superfine talcum powder or kaolin in one or more, barium sulfate preferably 1250 mesh sulfuric acid
Barium.
Described nucleator is alpha-crystal form nucleant agent N A-11.
Described lubricant is PP waxes.
Described coupling agent is titanate coupling agent or silane coupler.
Described antioxidant is the compound of one or both of Hinered phenols antioxidant 1010 or phosphite antioxidant 168,
Compound is both Hinered phenols antioxidant 1010 and phosphite antioxidant 168 by compound of 2/1 weight than formation.
The preparation method of PP composite material of the present invention, step are as follows：
(1) polypropylene, polystyrene, filler, nucleator, lubricant, coupling agent, antioxidant are placed in high-speed mixer
Middle stirring 3-5 minutes, obtain uniform mixed material；
(2) cooling and dicing after mixed material is extruded by parallel double-screw extruder melting, after homogenizing is dried, produce.
The present invention compared with prior art, has the advantages that：
High glaze of the present invention, high rigidity polypropylene material resin based on cheap polypropylene, add appropriate polyphenyl second
Alkene powder, filler, coupling agent, lubricant, antioxidant, by alpha-crystal form nucleant agent N A-11, promote blend polypropylene
Crystallization, improves crystallization rate, and makes crystal grain refinement, and the addition of Polystyrene powder, then serve heterogeneous nucleation in blend
Effect, further increase the crystallinity of blend, so as to effectively increase the surface gloss of material, polystyrene is with filling out
The addition for filling agent then ensure that material has suitable rigidity, and lubricant then improves the easy mold release of material, further increased
The surface gloss of end article.Compared with existing conventional art, the present invention greatly reduces the dosage of inorganic filler, effectively protects
The mechanical property of product is hindered.
