| description | The paper reveals the relevance of the use of adhesive polymer materials for the restoration of cars and machinery. Prerequisites for creation of universal polyurethane adhesive compositions of new generation for restoration of cars with the improved adhesive, physical-technical and operational properties which possess high resistance to aggressive environments and made of materials of domestic production are created. The advantage of bonding is that this method of restoring the elements of the car is applicable to materials of different nature.
Expediency of work is caused by presence in the market of expensive analogs of foreign production for restoration of details of cars in this connection there is a task in development of import substituting structures. Purpose: to study the degree of mass absorption of the adhesive composition in aggressive media. Methods: experimental studies to determine the effect of aggressive media on the adhesive composition are carried out in accordance with GOST No. 12020. Results: as a result of experimental studies, it was found that of the considered media, the most aggressive is water. It is the most polar of all considered aggressive media, has a number of features, for example, the small size of molecules. Scientific novelty: it was revealed that in most cases of exposure to aggressive media on samples of adhesive materials, there was a sharp increase in the degree of mass absorption for 20 days, and in the future the process is balanced. The Penza state University of architecture and construction has developed a fast-curing adhesive composition based on cold-curing polyurethanes in order to reduce the cost of restoring parts of various transport and technological machines. It can find application for restoration and repair of plastic elements of the car, and also in mechanical engineering. Practical significance: the main provisions and conclusions of the article can be used in the development of technologies for repair of automotive equipment with the use of polyurethane adhesive compositions. Experimental testing showed that the developed polyurethane modified adhesive compositions of a new generation with improved adhesive properties, reduced curing time, have high chemical resistance in almost all aggressive environments. |
