Abstract
The invention discloses a polyformaldehyde wear-resistant modified plastic comprising, by weight, 100 parts of polyformaldehyde, 10-20 parts of polytetrafluoroethylene, 10-15 parts of thermoplastic polyurethane elastomer (TPU), 0.2-0.6 parts of styrenated phenol, 0.1-0.3 parts of antioxidant 2246, and 1-3 parts of zinc stearate. The polyformaldehyde wear-resistant modified plastic provided by the invention has advantages of low friction coefficient, small hygroscopicity, good dimensional stability, high strength, good self-lubricating property, and the like. The polyformaldehyde wear-resistant modified plastic is mainly used for wear-resistant machine components and other components with high wear resistance.
Description
Technical field
The present invention relates to a kind of plastics, relate in particular to the wear-resisting modified plastics of a kind of polyoxymethylene.
Background technology
Polyoxymethylene (English: polyformaldehyde), be a kind of thermoplasticity crystalline polymer.Be described as " supersteel " or " match steel ", claim polyoxymethylene again, english abbreviation is POM.The polymkeric substance of common oxymethylene polymerization gained, the polymerization degree is not high, and is subject to thermal depolymerization.
Polyoxymethylene is a kind of smooth surface, and glossiness hard and fine and close material is yellowish or white, can be at life-time service in the-40-100 ℃ temperature range.Its wear resistance and self lubricity are also superior than most engineering plastics, and good oil resistant is arranged again, anti-superoxide performance.Very not acidproof, not anti-highly basic and the not radiation of anti-solar ultraviolet.
The tensile strength of polyoxymethylene reaches 70MPa, and water-absorbent is little, and dimensional stabilizing is glossy, and these performances are all good than nylon, and polyoxymethylene is the resin of highly crystalline, is the most tough and tensile in thermoplastic resin.Tool heat resistanceheat resistant intensity, flexural strength, resistance to fatigue intensity is all high, and wear resistance and electrical property are good.
But there is the shortcoming of wear resisting property difference in polyoxymethylene at present.
Summary of the invention
For solving the deficiency that prior art exists, technical problem to be solved by this invention provides the wear-resisting modified plastics of a kind of polyoxymethylene, has higher wear resisting property.
Technical scheme of the present invention is:
The wear-resisting modified plastics of a kind of polyoxymethylene is made of by weight following component: 100 parts of polyoxymethylene, tetrafluoroethylene 10-20 part, polyurethane termoplastic elastomer TPU 10-15 part, styrenated phenol 0.2-0.6 part, antioxidant 2246 0.1-0.3 part, Zinic stearas 1-3 part.
Above-mentioned each component is mixed, adopt the ordinary method granulation, can make the wear-resisting modified plastics of polyoxymethylene of the present invention.
Tetrafluoroethylene (Polytetrafluoroethene, english abbreviation is PTFE, (being commonly called as " plastics king "), trade name Teflon, then various places are different for this trade mark Chinese translation: the China's Mainland is translated into Hong Kong, Teflon and is translated into Teflon, Taiwan is translated into Teflon), the product of this material generally is referred to as work " non-sticky metallic coating "/" easy clean pot material "; It is a kind of synthetic macromolecular material that has used fluorine to replace all hydrogen atoms in the polyethylene.This material has the characteristics of antiacid alkali resistant, anti-various organic solvents, is dissolved in all solvents hardly.Simultaneously, tetrafluoroethylene has resistant to elevated temperatures characteristics, and its frictional coefficient is extremely low, so can do after the lubrication, also becomes the desirable coating of non-stick cooker and water pipe internal layer.Tetrafluoroethylene has outstanding excellent comprehensive performance, and is high temperature resistant, corrosion-resistant, sticking, self-lubricating, superior dielectric properties, very low frictional coefficient.As engineering plastics, can be made into polyfluortetraethylene pipe, rod, band, plate, film etc., generally be applied to the higher corrosion resistant pipeline of performance requriements, container, pump, valve and radar processed, high frequency Communication Equipment, radio component parts etc.
The wear-resisting modified plastics of polyoxymethylene of the present invention's preparation has characteristics such as low frictional coefficient, the water-absorbent small size is stable, intensity is high, self lubricity is good, is mainly used in abrasion resisting mechanical component and other high-wearing feature component.
Embodiment:
The wear-resisting modified plastics of a kind of polyoxymethylene, formed by weight by subordinate's component:
100 kilograms of polyoxymethylene, 15 kilograms of tetrafluoroethylene, polyurethane termoplastic elastomer TPU12 kilogram, 0.4 kilogram of styrenated phenol, 0.2 kilogram of antioxidant 2246,2 kilograms of Zinic stearass.
Above-mentioned each component is mixed, and melting mixing, extruding pelletization can make the wear-resisting modified plastics of polyoxymethylene of the present invention.Mixed processes can carry out in general mixing machine, and the control rotating speed is at 300-400 rev/min, and melting mixing, extruding pelletization operation can be carried out in general screw extrusion press.
After tested:
Tensile strength=45MPa;
Tension set is greater than 12%;
Flexural strength=65 MPa;
Modulus in flexure=2400 MPa;
IZOD notch shock (3.2mm)=60J/m;
Heat-drawn wire (1.82MPa)=120 ℃;
Molding shrinkage=1.4%.
The wear-resisting modified plastics of polyoxymethylene of the present invention's preparation has characteristics such as low frictional coefficient, the water-absorbent small size is stable, intensity is high, self lubricity is good, is mainly used in abrasion resisting mechanical component and other high-wearing feature component.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
