Abstract
The present invention relates to a polypropylene composition capable of transparentizing, which is an improvement of the transparency of transparent polypropylene. The polypropylene composition is formed by combining polypropylene and additive. The polypropylene composition is characterized in that the polypropylene composition has the following weight proportion: 99.0 to 99.97% of polypropylene, 0.01 to 0.6% of nucleating agents, 0.01 to 0.2% of primary antioxidant and 0.1 to 0.2% of auxiliary antioxidant. The polypropylene is in a homopolymerization structure or can be in an atactic copolymerization structure. The primary antioxidant is antioxidant in a phenolic antioxidant. The auxiliary antioxidant is a subsidiary magnetic acid ester class antioxidant or is a thioether class antioxidant. The nucleating agents are formed by combining two kinds of nucleating agents.
Description
One, technical field:
The present invention is a kind of improvement to the transparent polypropylene performance, especially to the raising of its transparency.
Two, background technology:
Polypropylene (PP) have good mechanical property, nontoxic, relative density is low, heat-resisting, chemical-resistant resistance, advantage such as machine-shaping easily, and transparent polypropylene is except that having above advantage, also have the transparency, glossiness and higher heat-drawn wire, can be widely used in injector for medical purpose, food product containers, transparent hot drink cup, microwave oven cooker, baby bottles etc. has certain requirement and resistant to elevated temperatures occasion to transparency.And present employed various transparent polypropylenes, general transparency does not all reach the ideal effect, and the transparency that has the transparent polypropylene production cost is higher preferably, therefore cause the cost of final product higher.
Three, summary of the invention:
(1) goal of the invention
The purpose of this invention is to provide a kind of transparent polypropene composition that a kind of production cost is low, transparency is high.
(2) technical scheme
The present invention is a kind of transparent polypropene composition, form by polypropylene and additive combination, the weight proportion of its composition is: polypropylene 99.0～99.97%, nucleator 0.01～0.6%, primary antioxidant 0.01～0.2%, auxiliary anti-oxidant 0.1～0.2%, polypropylene is the polypropylene of equal poly structure, also can be the polypropylene of random copolymerization structure, primary antioxidant is a phenolic antioxidant, and auxiliary anti-oxidant is phosphorous acid esters or thioether kind antioxidant, and nucleator is combined by two kinds of nucleators.
(3) technique effect
The present invention has transparency height, mist degree≤10%, good rigidly, resistant to elevated temperatures advantage, with the homo-polypropylene is the transparent polypropylene of base-material, its thermotolerance, rigidity, transparency are good, can be used for extruding, complete processing such as injection moulding, blown film, be widely used at aspects such as microwave articles for use, disposable foodstuff apparatus, medical apparatus.With the atactic copolymerized polypropene is the transparent polypropylene of base-material, having good performance aspect rigidity, the transparency, can be used for extrusion sheet, injection moulding, annotate, draw, the field of blowing is widely used.In addition, it is low that the present invention has a cost, the simple advantage of manufacturing process.
