Abstract
The invention relates to polypropylene combination whose components are as follows: 20-90wt% homopolymerization polypropylene, 10-65wt% copolymerization polypropylene, 0-15wt% inorganic filling, 0.1-1.5% the above three total weight heat oxygen stabilizer, 0.05-3.0% the above three total weight nucleating agent, 0.-10% the above three total weight lubricant. All of them are mixed with high speed, extruded granulation by twin screw extruder to gain the polypropylene combination. Compared with the existing, it has good mechanical properties, tensile strength (over 38Mpa), thermal endurance (95 degree centigrade), and shock resistance (over 350J/m), and be used to make building using pipe and fitting, large caliber industry using pipe, valve etc.
Description
One, technical field
The invention belongs to the applied chemistry field, particularly a kind of polypropene composition.
Two, background technology
Pure acrylic resin has characteristics such as density is little, corrosion-resistant, easy to process, range of application is more and more wider, but because the restriction of the physical and chemical performance of polypropylene own, it exist shock resistance poor, easily aging, shrinking percentage is big, use temperature should not surpass shortcomings such as 75 ℃.Therefore a lot of experts and scholars improve improving one's methods of acrylic resin performance in research, disclose as CN 94107609.3 and a kind ofly to prepare the high impact resistance polypropylene composition, but the highest of the tensile strength of goods reaches 28.3MPa with components such as solution styrene butadiene rubber, mineral fillers; CN01120444.3 discloses a kind of modified poly propylene composition of alternative ABS resin, though its tensile strength can reach 35Mpa, but notched Izod impact strength can only reach 180J/m, CN 00129469.5 discloses a kind of a kind of polypropylene composition for hot water pipe with the preparation of components such as atactic copolymerized polypropene and Masterbatch, and its yield strength is the highest has only 28.8Mpa.CN 97111916.3 discloses a kind of high-toughness polypropylene composition, has only 23.0Mpa though notched Izod impact strength can reach the 572J/m tensile strength.
Three, summary of the invention
In order to overcome deficiency of the prior art, improve the performance of polypropene composition, the invention provides a kind of polypropene composition, said composition not only has outstanding tensile strength, and has improved shock resistance and resistance toheat simultaneously.
Technical solution of the present invention is: a kind of polypropene composition is characterized in that the composition of said composition is:
