Abstract

Properties of not modified fenolformaldegidny adhesives, their structure and assignment are shown. Examples of adhesives on the basis of fenolformaldegidny resins, modified by polyvinylacetals are given. Improvement of properties of adhesives after their updating in such a way is shown. Strength characteristics of the adhesives joints executed with use of phenolopolyvinylacetal adhesives of brands VS-10T-U and VS-350 in initial condition and after artificial factors, simulating the operational are provided. It is shown that adhesives VS-10T-U and VS-350 provide operability of high-temperature tenzorezistors.
