| Title of the article | Investigation of gradient materials based on PVC and of diglycidyl ether 1,4-butanediol |
| Abstract. | Problem statement. The possibility of using epoxy monomer diglycidyl ether 1,4-butanediol for surface diffusion modification of PVC was investigated and its effect on the properties of the resulting composite materials was determined. Results. It is shown that as a result of impregnation of PVC in epoxy monomer to a small degree of swelling (up to 2 %) followed by curing in the hardener and heat treatment, the formation of interpenetrating structures in the surface layers of composites results in the formation of interfacial structures between them, and causes an increase in the surface microhardness with a maximum at swelling degree of 0,1 % (by 36 %). Conclusions. The significance of the results obtained for the construction industry lies in the fact that modifying the surface of finished PVC products without changing the internal part allows to strengthen all the material as a whole and increase its resistance to the influence of various external factors. At the same time, the consumption of the modifying additive is significantly reduced in comparison with the control in the volume of the material, and its efficiency is increased because of the high local concentration on the surface. |
