Abstract
Sealants are widely used in construction. They are used to seal detachable and permanent connections, structures, various joints and seams. The main volume of non-hardening sealants are sealants based on butyl rubber. These sealants, having a number of advantages, have a significant drawback - low weather resistance.
Weather-resistant sealants are of the greatest interest in construction. Such sealants can be obtained on the basis of ethylene-propylene rubber. It has high weather resistance, is resistant to ozone oxidation, but has low adhesion to various substrates.
The purpose of the research is to increase the adhesive strength of a non-hardening sealant based on ethylene-propylene rubber. To improve the adhesive strength, process additives are used. Bitumen was used as process additives. The article considers the effect of process additives on adhesive strength. It is shown that the use of process additives increased the adhesive strength by 1.5 - 2 times.
