Abstract
The soft preparation method who is with compound " metal; plastic composite " of a kind of filled polytetrafluoroethylene, it is characterized in that the filled polytetrafluoroethylene raw material band is covered on the composite plate of bronze powder through sintering, steel plate, one reinstates mill milling, then in the method for the composite board of making through the sintering plasticizing.This method technology is simple, low cost of manufacture, composite bed is even, precision is high.The composite board that this method is manufactured can be used to make sliding bearing, axle sleeve etc., and it is little, wear-resisting to have a coefficient of friction, and long service life can replace copper sheathing, reduces production costs greatly, replaces a large amount of copper materials.
Description
A kind of with the soft preparation method of filled polytetrafluoroethylene with compound " metal-plastic composite material ", belong to machine driving friction material manufacturing technique method.
Produce polytetrafluoroethylene (PTFE), metallic composite at present both at home and abroad, following two kinds of technologies are adopted on the composite plastic surface basically:
1. the polytetrafluoroethylene (PTFE) dispersion emulsion is condensed into pasty state, coated is at the copper powder surface of steel plate, and drying is removed moisture content, and is compound with mill milling.
2. the copper powder steel plate is cut into fritter, after the leveling, places on the support and PolytetrafluoroethylDry Dry-powder is layered on the surface with scraper plate, for preventing that dry powder is wiped off, spacing with 8 eye mesh screens.
Above-mentioned two kinds of method complex technical process be the more important thing is the coated inequality, and composite bed thickness is inconsistent, particularly spread the low composite bed thickness of powder precision and do not wait.
The invention provides a kind of polytetrafluoroethylene (PTFE)-metallic composite, mainly be to guarantee product quality by strictness control thickness of slab precision, and the precision of polytetrafluoroethylene (PTFE) shop powder is very crucial, the invention reside in to improve shop powder precision, simplifies technology simultaneously, reduces cost.
Technology of the present invention realizes by following content, is coated with one deck bronze powder 2 that the looses rolling composite of heating on sheet metal 1, has composition metal, the plastic composite of the compound one deck soft PTFE ribbon 3 of one side of bronze material at it.
The soft method of filled polytetrafluoroethylene with compound " metal, plastic composite ", be raw material band 1 that filled polytetrafluoroethylene is made and the steel plate 1 one of sintered, spherical bronze powder is reinstated mill milling, raw material band is softer, has good flowability, under the effect of milling train, raw material band is penetrated in the hole of copper ball 2 combines securely, and reach certain dimensional requirement with the copper powder steel plate, then through sintering. the polytetrafluoroethylene (PTFE) plasticizing meets the requirements of intensity.
The present invention has the advantages that technology is simple, cost is low, the product precision is high, the dry powder shop powder craft that adopts with the unit that has at present compares, yield rate is brought up to more than 90% by 50%, compare with the pasty state coating process, simplify technologies such as concentrated emulsion, pasty state coated drying and dehydrating, simplified technology, frock greatly.
Accompanying drawing 1 is soft compound " metal, the plastic composite " schematic diagram of being with of filled polytetrafluoroethylene of the present invention.
Accompanying drawing 2 is process flow diagrams of the present invention.
1. metallic plate, 2. copper powder, 3. polytetrafluoroethylene (PTFE).
Specific embodiments of the invention are described below:
Filled polytetrafluoroethylene raw material band prescription:
Filled polytetrafluoroethylene: lead powder=75: 25
Specification is 0.25mm * 200mm(thickness * width) that the raw material band and the steel plate one of sintered, spherical bronze powder are reinstated double-roll rolling mill is rolling, under the effect of milling train, the raw material band of good fluidity is penetrated in the hole of copper ball and combines with steel plate, and reach the size that requires. then through high temperature sintering, plasticizing polytetrafluoroethylene (PTFE), 360 °～370 ° of sintering temperatures, device therefor 151 sinter boxes.
This material can be manufactured antifriction materials such as sliding bearing, bearing holder (housing, cover), pad slide plate, guide rail.
Claims (2)
1, the soft preparation method of filled polytetrafluoroethylene with compound " metal--plastic composite ", comprise the composite board of the uniform spherical bronze powder of one side of required filled polytetrafluoroethylene raw material band, steel plate through sintering, it is characterized in that having the surface of bronze in above-mentioned composite plate, cover the above-mentioned filled polytetrafluoroethylene raw material band of one deck, one reinstates mill milling, through the sintering plasticizing, finish the soft manufacturing of filled polytetrafluoroethylene then with compound " metal, plastic composite ".
2, according to the method for claim 1, the composite plate of manufacturing, it is characterized in that burning clean temperature is 360 °～370 °.
