Abstract

The invention relates to the technical field of coating, in particular to temperature-resistance thermal-insulation heavy-duty anticorrosion coating, which comprises the following raw material components in percentage by mass: 10 to 40 percent of epoxy modified organosilicon resin, 5 to 20 percent of novolac epoxy resin, 8 to 20 percent of modified amine curing agent, 2 to 10 percent of flexibilizer, 0.1 to 1 percent of modified polysiloxane flatting agent, 0.01 to 0.1 percent of polysiloxane defoaming agent, 0.1 to 1 percent of polyacrylate dispersant, 4 to 11 percent of zinc phosphate, 4 to 10 percent of barite powder, 3 to 8 percent of titanium white, 0.01 to 0.1 percent of carbon black, 15 to 40 percent of potassium titanate whiskers and 2 to 20 percent of nano porous material. The organosilicon-modified epoxy resin adopted by the invention combines the high performance of epoxy resin and organosilicon resin, and the organosilicon-modified epoxy resin and the novolac epoxy resin compensate for respective defects. The coating has high anticorrosion performance, high high-temperature-resistance performance and high insulating performance, and the adhesion force, medium-resistance performance and thermal-insulation and heat-preservation performance of the coating are improved considerably.

Description

technical field [0001] The invention relates to the technical field of coatings in chemical technology, in particular to a heat-resistant, heat-insulating and heavy-duty anti-corrosion coating. Background technique [0002] Heat insulation coating is an effective means of heat insulation, and its research originated from the need for aircraft temperature control. Now, the application of thermal insulation coatings in the petroleum industry (used for oil storage equipment and the casing of transportation pipelines) has achieved good results. It reduces the volatilization of oil products and ensures the safety of storage tanks. However, high temperature resistant and heat insulating paint is a special kind of paint, which not only has the characteristics of general paint, but also has the functions of high temperature resistance and heat insulation. Due to the development of new technologies and the increase in demand, people have put forward higher and higher requirements fo...
