Abstract

The invention discloses an aqueous sunscreen thermal insulation coating and a preparation method thereof. The aqueous sunscreen thermal insulation coating comprises, by weight, 150-200 parts of waterborne polyurethane, 40-60 parts of an ultraviolet absorber, 25-30 parts of an infrared absorber, 10-20 parts of copper powder, 15-20 parts of molybdenum powder, 20-30 parts of ceramic beads, 20-30 parts of hollow beads, 3-5 parts of a defoamer, 3-5 parts of a leveling agent, 4-8 parts of a dispersant, 10-15 parts of an organosilicone hydrophobic agent, 3-5 parts of a curing agent, an appropriate amount of a solvent and an appropriate amount of a filler. The aqueous sunscreen thermal insulation coating has the advantages of good sunscreen and heat insulation effects, excellent water resistance, good heat radiation and reflection effects, energy saving, environmental friendliness, economy, safety and hygiene. The coating produced by the method can achieve accurate feeding and blending and has the best stirring effects. The preparation method can directly cool the stirred coating, greatly improves production efficiency and has low operation complexity.

Description

technical field [0001] The invention relates to a water-based sun-proof and heat-insulating paint and a preparation method thereof. Background technique [0002] Sunscreen and heat insulation materials are mainly used for heat insulation, energy-saving heat preservation and anti-ultraviolet radiation of buildings such as glass doors and windows, glass curtain walls, office buildings, private houses, etc. Ultraviolet radiation, used for glass heat insulation and sun protection of taxis, buses, excavators and other vehicles, used for glass heat insulation and electromagnetic wave shielding of aircraft, trains, ships and other vehicles, in the hot summer, the above facilities need to be protected from sun protection And heat insulation protection, which can effectively solve the damage caused by excessive outdoor temperature to the above-mentioned various facilities. Therefore, in order to ensure the long-term use of the above-mentioned various facilities, it is necessary to co...
