Abstract

The invention relates to a heat reflection paint with hollow glass microballoons, which comprises a surface paint and a prime paint, wherein the surface paint at least comprises silicone-acrylate emulsion, rutile type titanium dioxide and nano functional composite materials, and the prime paint at least comprises silicone-acrylate emulsion, hollow glass microballoon, hollow inorganic fiber and engineering cellulose. In the invention, the silicone-acrylate emulsion synthesized by the interpenetrating network technology has high diaphaneity and low absorbency, thereby ensuring the excellent weather fastness, the durability and the anti-stain performance of the paint film and maintaining the heat reflectivity and the heat-shielding performance of the coating for long. The synthesized nano functional composite materials have strong sunlight reflection effects, and the reflectivity can be more than 0.9, thereby ensuring the excellent reflective insulation function of the paint film. The selected special high molecular materials and the vacuum glass microballoons can effectively prevent the permeation of heat.

Description

technical field [0001] The invention relates to the field of solar heat-reflecting and heat-insulating coatings, in particular to a hollow glass bead heat-reflecting coating. The coating has the advantages of high reflectivity for visible sunlight and near-infrared sunlight, low thermal conductivity, and good heat preservation effect. Background technique [0002] As my country puts 1 billion square meters of civil buildings into use every year, the proportion of building energy consumption to the total energy consumption of the whole society has risen from 10% in 1978 to 27.5% at present, making buildings become my country's current major energy consumers. Continuous consumption of a large amount of energy poses a serious threat to industrial energy consumption. For this reason, the country began to enforce the 50% building energy-saving standard in 1997, and vigorously developing energy-saving houses has become a top priority. [0003] In buildings, the heat loss of the e...
