Abstract
The invention discloses high-strength talcum powder modified polypropylene plastics, which is formed by the following components in parts by weight: 100 parts of polypropylene, 20-40 parts of talcum powder, 2-4 parts of titanium dioxide, 10-15 parts of PP-g-MAH compatilizer, 0.1-0.2 part of isopropyl tri(dioctyl phosphoric acid acyloxy) titanate, 0.1-0.2 part of dimerization diisooctylacidphosphate magnesium stearate, 10-20 parts of cyanuric acid melamine, and 0.1-0.3 part of antioxygen 168. The high-strength talcum powder modified polypropylene plastics has higher mechanical property.
Description
Technical field
The present invention relates to a kind of composite plastic, relate in particular to a kind of high strength talcum powder modified polypropylene plastic.
Background technology
Polypropylene has many good performances as a kind of general-purpose plastics, but, poor heat resistance low because of physical strength, the defective such as contraction deformation is large, creep resistance is poor, on using, particularly as structured material, be very limited, can not be as high performance engineering plastics.Therefore, polypropylene is carried out modification, making it through engineering approaches just becomes an important research topic.
Talcum powder is a kind of mineral by the layered silicate crystal composition, adopts the PP of talc, good heat resistance, and shrinking percentage is low, good stability of the dimension, hardness is high.Talc PP matrix material has been widely used in the production of trolley part and articles for daily use, its product with do not fill talcous PP compare have good apparent mass, low shrinking percentage and higher heat-drawn wire, yet because the affinity of two-phase interface is not strong, talcous direct filling often causes the decline of some mechanical properties, thereby the application of matrix material is restricted.It is carried out the interface affinity that surface modification treatment can be improved talcum powder and polymkeric substance effectively, improve polymkeric substance to talcous wetting ability, improve the dispersion state of talcum powder in the superpolymer base-material, thereby improve the physical and mechanical property of matrix material.
Summary of the invention
The deficiency that exists for solving prior art, technical problem to be solved by this invention is to provide a kind of high strength talcum powder modified polypropylene plastic.
Technical scheme of the present invention is:
A kind of high strength talcum powder modified polypropylene plastic, formed by weight by following component: 100 parts of polypropylene, talcum powder 20-40 part, titanium dioxide 2-4 part, PP-g-MAH compatilizer 10-15 part, sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester 0.1-0.2 part, dimerization di (isooctyl) phosphate Magnesium Stearate 0.1-0.2 part, melamine cyanurate 10-20 part, irgasfos 168 0.1-0.3 part.
Above-mentioned each component is mixed, adopt the ordinary method granulation, can make high strength talcum powder modified polypropylene plastic of the present invention.
The high strength talcum powder modified polypropylene plastic of the present invention's preparation has higher mechanical property.
