Abstract

The invention discloses a novel water-based waterproof and heat-insulating decorative coating and its preparation technology thereof and belongs to the field of building coatings. The coating comprises, by weight, 30% to 60% of water-based acrylic resin, 2% to 10% of a water-based waterproofing agent, 15% to 35% of a water-based colorant, 3% to 12% of a heat insulating functional material, 2% to 9% of an aid and the balance of deionized water. The preparation technology comprises preparing a water-based colorized colorant and adding the water-based colorized colorant into a coating preparation system to obtain the novel water-based waterproof and heat-insulating decorative coating. Through combination of the water-based colorant containing an infrared reflection nano-pigment, the waterproof and heat-insulating decorative coating which has multiple color systems and high gloss and is used for a decorative tile, the wall of the building and the surface of the metal sheet is obtained. The water-based waterproof and heat-insulating decorative coating has solar reflectivity of 87%. A heat insulation temperature difference test result shows that a sample plate coated with the water-based waterproof and heat-insulating decorative coating has a temperature of 15 DEG C lower than that of a reference sample plate, sample aging resistance time is 1500h and fading and pulverization are avoided.

Description

technical field [0001] The invention belongs to the field of architectural coatings, and in particular relates to a waterproof and heat-insulating decorative coating applicable to decorative tiles, building walls and metal plate surfaces and a preparation process thereof. Background technique [0002] According to statistics, building energy consumption accounts for 30% of the total energy consumption of the whole society, and my country's building energy consumption is 2-4 times that of developed countries. Improving the thermal insulation performance of buildings, improving the use function of buildings, and saving energy and reducing consumption are another important considerations in the design of building material selection. The thermal insulation coating can reflect the solar infrared and ultraviolet rays with a wavelength in the range of 400nm-2500nm, so as to avoid the accumulation of heat from the sun on the surface of the object and play a role in heat insulation. ...
