Resistance to Wear of Polymer Solutions and Polymer Concretes Based on Thermoreactive Resins,
Abstract
The wear resistance was determined of several compounds based on epoxy resins ED-5, ED-6, E-37, and E-40, polyester resin PN-1, and furfural acetone monomer. The epoxy compounds were more resistant to abrasion by sand blasting than the other compounds. The maximum wear angle (alpha) of concretes in sand blasting is 90 degrees for the unfilled epoxy compounds. Alpha is similar to 30 degrees. The addition of 10-30 percent Thiokol NVT-1 to ED-5 decreases its wear resistance and shifts alpha to 60-75 degrees. The plastification ED-5 with 10 percent dibutylphthalate decreases its wear resistance, leaving alpha unchanged. Fillers increase alpha and decrease the wear resistance. The best fillers are metal powders and corundum.
