Problems solved by technology

The former has poor rust resistance, salt spray resistance, and poor gloss and color retention. Although the latter has made great progress, its pulverization and other factors cannot be compared with the excellent salt spray and heat insulation effect of the siloxane paint film, which is full and does not change color.

Abstract

The invention provides a polysiloxane heat-reflective topcoat and a preparation method thereof. The polysiloxane heat-reflective topcoat comprises a component A and a component B, and the weight ratio of the component A to the component B is 8:(1-1.5); the component A comprises the following ingredients by weight: 30-40 parts of polysiloxane resin, 3-8 parts of a thermal insulation material, 0.6-0.9 part of a stabilizer, 25-48 parts of a mixed solvent, 0.2-0.5 part of a dispersant, 17-33 parts of an anti-aging pigment and an anti-aging filler, and 0.2-0.5 part of an anti-settling agent; the component B comprises the following ingredients by weight: 60-70 parts of a curing agent and 18-35 parts of a curing agent solvent. The polysiloxane heat-reflective topcoat is high in ageing-resistant performance, weather resistance and chemical resistance, has a heat reflection function, can be suitable for various construction methods, and is good in recoatability and excellent in cost performance; besides, external corrosion protection of the surface of coated steel is achieved, a lot of coating expenditures can be reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a polysiloxane heat-reflecting topcoat and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] In steel structure anti-corrosion engineering, coating has always been the most important, most economical and effective anti-corrosion method. At present, the corrosion of ships and general steel structures is mainly manifested in the damage of internal structures and parts exposed to atmospheric environments such as sunlight and salt spray. [0003] The coatings used in domestic maintenance of steel structures and cabins are mainly alkyd and epoxy ester antirust primers, while alkyd coatings are mostly used for ship shells. The antirust primers and topcoats of these varieties have a protection period of only 1-2 years due to their poor water resistance, weather resistance, and chemical resistance, and even less than half a year in harsh environments. [0004] In large-scale ant...
