Abstract

The invention discloses an environment-friendly heat insulation coating and belongs to the field of coatings. The environment-friendly heat insulation coating comprises the following components in parts by weight: 25-40 parts of fluorinated acrylic emulsion, 3-15 parts of titanium dioxide, 5-15 parts of a colorized hollow ceramic micro-bead, 0.3-1.0 part of a defoaming agent, 0.6-1.5 parts of a thickening agent, 0.08-0.25 part of propylene glycol, 0.5-2.0 parts of a dispersant and 25-45 parts of deionized water. The environment-friendly heat insulation coating disclosed by the invention has the beneficial effects of good in base material bonding strength, no empty drums, no falling, good toughness, high elongation rate, good waterproofness and long service life; the adopted colorized hollow ceramic micro-bead has various colors, and no pigments are added for regulating the color, so the toxicity and organism volatility of the coating are reduced.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly thermal insulation coating. Background technique [0002] Solar energy is a necessary condition for human survival and life, but strong radiation also brings inconvenience to human production and life. The energy of sunlight radiated to the surface of the earth is about 750w / m per second 2 , my country's annual sunshine time of more than 2200 hours of the region accounts for more than two-thirds of my country's land area. Under the irradiation of sunlight, it gathers on the surface of the irradiated object, and the heat on the outer surface of the object continues to accumulate, and the temperature continues to rise. For example, when sunlight shines on a metal plate in summer, its surface temperature can reach 70-80°C. In actual production and life, if it is necessary to reduce the temperature rise caused by solar radiation, it needs to consume a l...
