Heat insulation waterproof anti-corrosive paint

Abstract

The invention discloses a heat insulation waterproof anti-corrosive paint, which comprises 15-18 parts of polystyrene foam, 15-20 parts of petroleum resin, 6-10 parts of epoxy resin, 20-40 parts of xylene, 6-9 parts of butyl acetate, 8-20 parts of anti-corrosive pigments, 10-20 parts of heat insulation filler, 15-25 parts of heat insulation reinforcing materials, 7-10 parts of plasticizer and 0.5-2 parts of carbon black. The paint of the invention has good heat insulation, waterproof and anti-corrosive effects and is widely applicable to various buried pipelines, chemical pipelines and devices, steel frame structures, towers, iron products, cement buildings, mining machineries, ships, petrochemical processing storage tanks and environment protection engineering and can be used as the matched primer of various heat insulation paint; and moreover, the paint has loose requirements on the construction surface and can be directly brushed on the surface of a rusty member to realize a good protection effect, and the construction difficulty is low.

Description

technical field [0001] The invention relates to a protective coating, in particular to a heat-insulating, waterproof and anti-corrosion coating. Background technique [0002] Polystyrene (PS) is a polymer compound that is not easy to degrade and has a wide range of uses. However, polystyrene is generally used for one-time use, and it is discarded in nature after use. Because it is difficult to degrade, it cannot be used by microorganisms. It will exist for a long time in nature and form white pollution. If this waste polystyrene can be effectively utilized, it will not only reduce environmental pollution, but also turn waste into treasure and realize the reuse of resources. [0003] Polystyrene has good water resistance, thermal insulation and insulation properties. These properties of PS make it possible to be manufactured as thermal insulation, waterproof, and anti-corrosion coatings. However, the coating adhesion and film-forming properties of PS are very poor, making it...
