Description

High-gloss nano barium sulfate reinforced polypropylene resin composition
Technical field
The present invention relates to a kind of high-gloss nano barium sulfate reinforced polypropylene resin composition, this material high gloss, high workability, mechanical property excellence can be widely used in the shell of household electrical appliance, belong to the polypropylene modification technical field.
Technical background
Inexpensive, the light weight of polypropylene (PP), corrosion-resistant, have good processibility, good, the applied range of mechanics harmony, best thermotolerance is arranged in resins for universal use.Polypropylene is widely used on household electrical appliance and automotive industry, and the through engineering approaches tendency is fairly obvious.But the glossiness of common mineral-filled Reinforced Polypropylene is lower, has limited its application on the household appliances shell that surface aesthetic is had relatively high expectations.
The traditional method that improves the polypropylene glossiness is to add crystallization nucleating agent in polyacrylic polymerization process, but the final luster effect of material of this approach gained can not reach the requirement of use fully, and similarly the polypropylene trade mark is also few on the market.
Summary of the invention
The object of the present invention is to provide a kind of high-gloss nano barium sulfate reinforced polypropylene resin composition with high gloss, high workability, mechanical property excellence.
For realizing above purpose, technical scheme of the present invention provides a kind of high-gloss nano barium sulfate reinforced polypropylene resin composition, it is characterized in that, form by following raw materials by weight percent: polypropylene 60-80%, nano barium sulfate 5-20%, talcum powder 5-20%, compatilizer 2-10%, oxidation inhibitor 0.1-1%, lubricant 0.1-0.5%.
Described polypropylene is Co-polypropylene or homo-polypropylene, can be single also can be blended; Described nano barium sulfate is a white powder, and particle diameter is 100-300nm; Described talcum powder is a white powder, and particle diameter is the 800-2000 order; Described compatilizer is the oligopolymer of the graft polymerization of polypropylene grafted unsaturated acid or acid anhydrides, is PP-G-MAH, and its melting index is 40-150g/10min, and percentage of grafting is 0.5-1%; Described oxidation inhibitor is the compound system of a kind of Hinered phenols antioxidant and phosphite ester kind antioxidant, be 1: 1 1010/168; Described lubricant is a fatty acid metal soap class, is calcium stearate, Zinic stearas, barium stearate or Magnesium Stearate.
A kind of preparation method of high-gloss nano barium sulfate reinforced polypropylene resin composition is characterized in that, its method is as follows;
(1) weighs raw material by weight percentage;
(2) all raw materials are put into high-speed mixer and mixing 2-5 minute;
(3) discharging;
(4) raw materials mixed is placed the screw extrusion press extruding pelletization, processing temperature is at 150-220 ℃, and the screw rod revolution is at 180-600 rev/min.
Inexpensive, the light weight of polypropylene (PP), corrosion-resistant, have good processibility, good, the applied range of mechanics harmony, best thermotolerance is arranged in resins for universal use.
Nano barium sulfate can improve the intensity of acrylic resin, and it can give polypropylene good glossiness again simultaneously.
Talcum powder is a kind of silicates mineral powder, can improve polyacrylic intensity, reduce polyacrylic shrinking percentage, reduces the cost of material simultaneously.
The oligopolymer of the graft polymerization of polypropylene grafted unsaturated acid or acid anhydrides has the flowability of superelevation, as compatilizer, can improve the dispersiveness of metallocene-polyolefin in acrylic resin, improves the viscosifying power of the two.
Oxidation inhibitor can improve composition in the antioxidant property of the course of processing and the ageing resistance in the use.
Fatty acid metal soap class can improve the materials processing flowability as lubricant, reduces frictional coefficient, improves smooth property, improves surface luster.
Advantage of the present invention be have high-luster, high workability, mechanical property excellence, processing characteristics is good, cost is low, has adapted to the high-performance of household electrical appliance and automotive industry, development trend cheaply, can be widely used in fabricator electrical appliance and auto parts machinery.
