Study On CuZnSnPbAg Alloy System And Phenolic Resin Composite Material

In this paper, we study metal and resin composite material. Using metal and resincomposite in order to solve problem of metal poor self-sharpening ability and poorthermal stability of resin base,so as to realize metal resin composite base superhardabrasive with resin base of high efficiency and high life, with metal matrix tooptimize combination of efficient and durable.This experiment selects the copper, zinc, tin, lead, silver for metal alloy system,high temperature resistant phenolic resin for resin system.To study the effect ofpreparation of metal powders by mechanical alloying，low volume ratio of lowtemperature sintered metal alloy， metal system and phenolic resin compositetechnology，the metal resin composite material properties and the microstructure.By means of different particle size of metal ball mill time system, metallographicanalysis of XRD and sintered body. Mechanical alloying can refine the metal powderparticles, and promote the metals alloying metal powder at the same time morehomogenization and centralization. Longer duration of ball mill, metal powdersintering activation energy increases for low temperature sintering densification ofsintered body and the improvement of mechanical properties.By studying the different ball milling time of particle size of metal alloy system,XRD and sinter metallurgical suggests that: Low temperature sintering，appropriate toincrease the content of zinc can improve the strength and hardness of the sinteredbody; Copper content is too high or too low, the performance of the sintered body isnot good, The strength and hardness of the sintered body is best when the coppercontent50%,460℃sintering heat preservation2min strength is206MPa, hardnessis161HV. Through melting point of three kinds of phenolic resin, liquid, gel time, thermalanalysis, infrared spectrum analysis and the analysis of the mechanical properties of the curedresearch shows that:0309phenolic resin heat resistance at500℃, the liquidity is moderate,good mechanical properties, is suitable for the metal resin composite material.Research metal resin composite resin content before and after sintering, theeffect of sintering temperature on the mechanical properties and SEM analysissuggests that: the resin content10%,460℃sintering,heat preservation2min, The strength of the metal composite resin up to167.39MPa, B hardness92.5HRB.BySEM, Before the sintering, metal and resin respectively to form two systems and resinfor flake, metal and resin bond does not close. With the increase of sinteringtemperature, resin flake structure gradually disappear, metal particles have a largerparticles to become uniform granules, metal and resin combination of more closely.When the sintering temperature of460℃,instead of clear resin structure in thesintered body combined closely with the metal resin coexistence state, At this timemost closely the complex. When the sintering temperature over460℃，Sntered bodystructure is loose and appearflocculent，maomao shape-the product of carbonationdecomposition of resin.
