The piston is made of phenolic molding plastic: publishing the patent
National resin network (www.360gsz.com) April 13, 2012: a piston made of phenolic molding plastic is published. The invention discloses a phenolic molding compound used to make cars and motorcycle pistons, according to experts from China's national phenolic resin network (www.pf-e.cn). The phenolic molding compounds, phenolic resin for 10 ~ 40%, the dosage of inorganic filler for 15 ~ 50%, reinforced material consumption is 20 ~ 55%, the amount of 2 ~ 10% curing agent, plasticizer dosage is 1 ~ 8%, curing catalyst dosage is 1 ~ 10%, colorant dosage of 0 ~ 10%. The present invention are used in the manufacture of automobile, motorcycle piston of phenolic molding compound, its molding products with high dimensional stability, high hardness, high mechanical strength, heat distortion temperature, high temperature thermal weightlessness rate is low, after molding shrinkage rate and low shrinkage rate, bibulous rate is low.
