Description
Technical field
The present invention relates generally to Material Field, particularly relates to a kind of fiber reinforced polypropylene compound material.
Background technology
Polypropylene also comprises the multipolymer of propylene and a small amount of ethene.Be generally translucent colorless solid, odorless is nontoxic.The highly crystallized due to compound with regular structure, therefore fusing point can up to 167 DEG C.Containing cobalt, zirconium, corrosion-resistant, goods used vapour sterilization be its outstanding advantages.Density is little, is the lightest general-purpose plastics.Shortcoming is that low-temperature impact resistance is poor, more aging, but can be overcome respectively by modification;
Polypropylene is the polymkeric substance of nontoxic, odorless, tasteless oyster white height crystallization, is one of kind the lightest in current all plastics.It is stable especially to water, and the water-intake rate in water is only 0. 01%, molecular weight about 80,000 one 15 ten thousand.Good moldability, but because of shrinking percentage large, thick article easily caves in, and to the higher part of some dimensional precisioies, is difficult to reach requirement, product surface good luster, is easy to painted.
Along with polypropylene is more and more applied in the various field such as daily life, suitability for industrialized production, improving its performance, play that it plays better, more excellent performance, is object of the present invention.
Summary of the invention
The object of the invention provides a kind of fiber reinforced polypropylene compound material.
