The article describes the problem arising in lining of metal surfaces by ultrahigh molecular weight polyethylene, which consists in loosening of joints due to ingress of high dispersed dust into gaps between metal and polymer sheet. The method for solving this problem using the rubber–polymer two-layer material representing strongly interconnected sheets of rubber and ultrahigh molecular weight polyethylene is proposed. The use of the two-layer rubber–polymer composite as a lining material makes it possible to use adhesive joint and allows it to be tightly fastened to the metal surface when using a bolted joint. High elasticity of the rubber layer allows sealing gaps between lining material and metal surface. Also, a significant advantage of the rubber layer is damping of impacts of cargo (ore) on the lined surface during loading, unloading and transportation. The rubber layer can be made of various rubbers with the necessary properties for the given operating conditions (oil-resistant, wear-resistant, cold-resistant, etc.) depending on the task and application field of the lining. The method for increasing adhesion interaction between an elastomer based on butadiene-styrene rubber and ultrahigh molecular weight polyethylene is presented. The influence of the activity of carbon black and diphenylguanidine in the rubber mixture on the adhesion between the elastomer and ultrahigh molecular weight polyethylene is considered. The change in the supramolecular structure of the interface of ultrahigh molecular weight polyethylene under filling of diphenylguanidine into the rubber mixture is shown by scanning electron microscopy.
