Abstract
The invention disclose a formula of weather-resistant polypropylene, which comprises polypropylene, a filler, an antiaging agent, a photostabilizer, an antistatic agent and a plasticizer, wherein the filler is calcium sulfate, the antiaging agent is dilauryl thiodipropionate, the photostabilizer is titanium dioxide, the antistatic agent is calcium phosphate, and the plasticizer is dibutyl phthalate. According to the formula, the weather-resistant polypropylene has the advantages of favorable ultraviolet resistance, favorable oxidation resistance, high plasticity, strong mechanical properties and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of weather-proof polypropylene.
Background technology
In recent years, along with the raising of Vestolen PP 7052 production technique, the improvement of polymerization technique, high-flowability polypropylene Products Development and application obtain remarkable progress; Weather-proof polypropylene has advantages such as good processing characteristics, mechanical property, weather resistance and resistance toheat.The Vestolen PP 7052 injection-molded item is used widely in fields such as packing, transportation, household electrical appliances, automobile, offices.
Polypropylene product is divided into homopolymerization type and copoly type, and copoly type is divided into block copolymerization type and random copolymerization again.When the high workability HOPP receives low-temperature impact, poor toughness, big, the easy buckling deformation of product of molding shrinkage, but its good fluidity, tensile strength, flexural strength height; The high workability COPP has improved low-temperature impact property, has snappiness preferably, has higher flow rate and the physicals of applauding, and makes the design of baroque large thin-wall injection-molded item become feasible; And can shorten the process-cycle in process of production, reduce processing temperature, injection pressure and energy consumption; Having processing can be good, punch die reaches advantages such as the product buckling deformation is few easily; Comparatively speaking, the flowability of COPP is slightly poorer than HOPP, and tensile strength, flexural strength are not as high workability HOPP height.
A lot of polypropylene products all have various situation to occur in use, as fade, situation such as oxidation, deliquescing occur, greatly reduce the attractive in appearance of household electronic products, and shortened work-ing life.Therefore, a kind of weather-proof polypropylene product is our urgent problem.
Summary of the invention
The object of the present invention is to provide the prescription of a kind of antiultraviolet, anti-oxidant, plasticity good, mechanical property is strong weather-proof polypropylene.
Technical scheme of the present invention is; A kind of prescription of weather-proof polypropylene comprises Vestolen PP 7052, weighting agent, inhibitor, photostabilizer, static inhibitor, softening agent, and described weighting agent is a calcium sulfate; The thio-2 acid silicone grease in February that inhibitor is; Photostabilizer is a titanium oxide, and static inhibitor is a calcium phosphate, and softening agent is a Witcizer 300.
In preferred embodiment of the present invention; Each composition weight percent of the prescription of described weather-proof polypropylene is that Vestolen PP 7052 accounts for 75%-85%; Calcium sulfate accounts for 10%-15%, and thio-2 acid silicone grease in February accounts for 0.5%-1%, and titanium oxide accounts for 1%-1.5%; Calcium phosphate accounts for 1.5%-2.5%, and Witcizer 300 accounts for 2%-5%.
In preferred embodiment of the present invention, each composition proportion of the prescription of described weather-proof polypropylene is that Vestolen PP 7052 accounts for 78%, and calcium sulfate accounts for 14%, and thio-2 acid silicone grease in February accounts for 0.7%, and titanium oxide accounts for 1.2%, and calcium phosphate accounts for 2.1%, and Witcizer 300 accounts for 4%.
According to the invention is a kind of prescription of weather-proof polypropylene, makes the weather-proof polypropylene that makes have antiultraviolet, anti-oxidant, effect such as plasticity good, mechanical property is strong.
