Description
Technical field
The present invention relates to high polymer alloy field, be specifically related to flame-proof abrasion-resistant PA66, PC, PVDF alloy material and preparation method thereof.
Background technology
PA66 claims again nylon 66; Be a kind of translucent or opaque oyster white crystallization shape polymkeric substance, be widely used in the part of manufacturing machine, automobile, chemistry and electrical means, in order to improve the mechanical characteristics of PA66, often add various properties-correcting agent.Glass is exactly modal additive, sometimes in order to improve shock resistance, also adds synthetic rubber, and PA66 has non-fusibility to many solvents, but to acid and the resistibility of some other chlorizating agent a little less than.
Polycarbonate (being called for short PC) is the high molecular polymer that contains carbonate group in molecular chain, can be divided into the broad varietys such as aliphatics, aromatic series, aliphatic-aromatic according to the structure of ester group.Wherein because the mechanical property of aliphatics and aliphatic-aromatic polycarbonate is lower, thereby limited its application aspect engineering plastics.
PVDF, english abbreviation poly (vinylidene fluoride), mainly refer to the multipolymer of vinylidene fluoride homopolymer or vinylidene and other a small amount of fluorine-containing vinyl monomers, it has the characteristic of fluoro-resin and resins for universal use concurrently, except thering is good chemical resistance, high thermal resistance, scale resistance, weathering resistance, outside resistance to x radiation x performance, also there is piezoelectricity, dielectricity, the properties such as pyroelectricity, in chemical structure, with fluorine one carbonization, closing bond closes, this structure with short key matter forms the most stable the most firmly combination with hydrogen ion. thereby fluorocarbon coating has special physical and chemical performance, not only there are very strong wear resistance and shock resistance, and there are very high fade resistance and anti-ultraviolet property in extremely harsh and rugged environment.
Summary of the invention
