Abstract

The invention provides a high-gloss high-adhesion heat insulation coating for an outdoor steel structure. The high-gloss high-adhesion heat insulation coating for the outdoor steel structure is prepared from the following raw material components in parts by weight: 40 to 60 parts of waterborne acrylic emulsion, 5 to 8 parts of hollow glass bead, 8 to 12 parts of nanometer titania, 1 to 3 parts ofa silane coupling agent, 0.1 to 0.3 part of an antiseptic antimildew agent, 0.1 to 0.3 part of a wetting agent, 0.3 to 0.8 part of a dispersing agent, 0.1 to 0.3 part of an anti-flash rust agent, 0.1to 0.3 part of a defoaming agent, 3.0 to 5.5 parts of a coalescing agent, 0.1 to 0.3 part of a thickening agent, 1 to 3 parts of a flatting agent, and 20 to 30 parts of deionized water.

Description

technical field [0001] The invention relates to a heat-insulating coating, in particular to a high-gloss and high-adhesion heat-insulating coating for outdoor steel structures and a preparation method thereof. Background technique [0002] "Heat insulation coating": refers to a functional water-based coating developed in recent years that blocks, reflects, and radiates near-infrared heat from the sun to insulate and cool the roof, save energy and reduce consumption. It has heat insulation, waterproof, antirust, anticorrosion , short construction period and quick effect, fully replace the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main types of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiant heat insulation coatings. In addition to the above three types of heat insulation coatings, a heat ins...
