A friction control agent for train wheel treads was prepared by using unsaturated polyester,zircon sand,fluorite, graphite,molybdenum disulfide as raw materials,and the effects of temperature,pressure and time on the performance of friction control agent were explored. It is found that with the increase of temperature from 110 ℃ to 160 ℃,the curing time of the friction control agent is decreased,and the hardness is increased first and then decreased. With the increase of pressure from 20 MPa to 70 MPa,the curing time is decreased,and the hardness is increased first and then decreased. Orthogonal experiments were performed at a selected temperature from 140 ℃ to 160 ℃,a selected pressure from 40 to 60 MPa,and a selected time form 2 h to 3 h,and the optimal process conditions were as follows:pressure of 60 MPa,time of 2 h and temperature of 150 ℃. Based on the range analysis,it is found that the influence of the three factors is in order of pressure,time and temperature. The bending strength of the friction control agent prepared under optimized conditions is 17. 13 MPa,the compression strength is 25. 73 MPa,the hardness is 65,the density is 2. 12 g/ cm3,the friction coefficient is stable between 0. 3 and 0. 4,and it has good anti-wear properties. The results of SEM analysis show that the inorganic fillers in friction control agent are evenly wrapped by the resin,and the structure of friction control agent is stable. The thermogravimetric test result shows that the friction control agent begin to loss weight loss at 200 ℃ and lass weight completely at 800 ℃,which meet the performance requirements.
