Investigation of the physico-mechanical properties of a low-density polymer insulation coating
Incoming article date: 17.04.2020The results of a study of the development of a polymer heat-insulating coating for the insulation of heated metal surfaces of industrial and engineering equipment, industrial plants, building structures, working surfaces of pipelines operated at low (up to 1000C) temperatures are presented. The coating was developed on the basis of a polymer binder, which is a mixture of styrene-butadiene rubber and acrylic polymer, hollow carbon microspheres, pigment and water. The use of hollow carbon microspheres in this coating as a filler in an amount of 20.0 to 30.0 parts by weight reduces the thermal conductivity of the coating, compared with the known containing hollow glass or ceramic microspheres.
