- Abstract
- Paint coatings with optimal performance properties are an important element in the safety and efficiency of marine and river vessels, as well as other objects exploited in the aquatic environment. In this work for modification of paint and varnish coatings we used a material based on calcium hydrosilicate, obtained by hydrothermal method from technogenic waste in the form of borogypsum. The synthesis product with specific surface 155.2 m2/g and density 3.1 g/cm3 is characterized by the presence of phases of calcium sulfate, tobermorite and xonotlite and consists of mainly from needle particles. The influence of calcium hydrosilicate, partially replacing calcium carbonate, on the properties of paint coatings based on acrylic copolymer has been studied. Physical and mechanical properties, antifouling effect, water absorption and erosion rate of paint coatings were studied.The results of the study showed the efficiency of calcium silicate use to improve the physical and mechanical properties of coatings: an increase in strength by 1.5 times was found. At the same time, the addition of calcium hydrosilicate at partial replacement of calcium carbonate does not decrease the antifouling effect.
