Abstract

The invention discloses a sound absorbing, sunscreen and heat insulation coating for a building and a preparation method thereof. The sound absorbing, sunscreen and heat 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 to 5 parts of a curing agent, 30 to 40 parts of vermiculite micro-powder, 30 to 40 parts of perlite micro-powder, and appropriate amounts of a solvent and a filler. The coating has good sunscreen and heat insulation effects, excellent water resistance, good heat radiation and reflection effects, saves energy, is environmentally friendly, safe and health, realizes precision feeding and blending, and has optima stirring effects. The stirred coating can be directly cooled so that preparation efficiency is greatly improved and operation complexity is reduced.

Description

technical field [0001] The invention relates to a sound-absorbing, sun-proof and heat-insulating coating for buildings and a manufacturing 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...
