Abstract

Belonging to the field of materials, the invention discloses a modified PP material. The formula involves PP, nano-calcium carbonate, zinc stearate, titanate, EVA, and polyethylene wax. Nano-calcium carbonate and talc powder have toughening and reinforcing effects on PP, and can significantly improve the mechanical properties of PP, so that PP can be applied more widely. Nanoscale calcium carbonate has small average particle size and large specific surface area, and filling of PP with the nanoscale calcium carbonate can significantly improve the mechanical strength. Fillers with different particle shapes can have different effects on the mechanical properties of PP, and the use of flake talc powder can improve the impact resistance of PP.

Description

A kind of PP material of modification
Technical field
The invention belongs to Material Field, particularly relate to a kind of PP material of modification.
Background technology
PP molecular polarity is less, and degree of crystallization is high, good stability of the dimension, and hardness is high, good heat resistance, and chemical stability is excellent.But the tensile strength of PP and shock strength lower, toughness is poor, and molding shrinkage is comparatively large, limits its application in engineering to a great extent.
Summary of the invention
Object of the present invention, for providing a kind of PP material of modification, makes the simple and effective realization of the modification of PP.
The present invention is achieved in the following ways: comprise PP, nano-calcium carbonate, Zinic stearas, titanic acid ester, EVA, polyethylene wax.
In formula, the number of each component is: PP 100 parts, weighting agent 3-7 part, Zinic stearas 1-3 part, coupling agent 0.5-1.5 part, EVA 2 parts, lubricant 1 part.
Described weighting agent uses nano-calcium carbonate.
Described coupling agent is titanic acid ester, and lubricant is polyethylene wax, and EVA is ethene-vinyl acetate copolymer.
Beneficial effect of the present invention is: nano-calcium carbonate and talcum powder have the effect of toughen and intensify to PP, can significantly improve the mechanical property of PP, thus makes it more can widespread use.The median size of nano level calcium carbonate is little, and specific surface area is large, is filled in PP and can significantly improves its mechanical strength.The weighting agent of different particle shapes can produce different impacts to the mechanical property of PP, uses platy talc can improve the shock resistance of PP.
Embodiment
(1) filler pre-treatment: adopt Zinic stearas to do coating, play the effect of coated inorganic particle, the particle aggregation of dispersion can be prevented together, reduce the melt viscosity of material, improve the mobility of material.Together with being coupled at very well with organism with titanic acid ester inorganics, adopting common high-speed mixer batching to be mixed, ensure that inorganic particulate is dispersed in PP as far as possible.
(2) extruding pelletization: adopt typical twin screw extruder and common head, select suitable machine-shaping temperature, screw speed etc. achieve the extruding pelletization of PP modifying material.

Claims (4)

1. a PP material for modification, is characterized in that: comprise PP, weighting agent, Zinic stearas, coupling agent, EVA, lubricant.
