Reflective heat insulation waterproof paint and preparation method thereof

Abstract

The invention discloses reflective heat insulation waterproof paint. The reflective heat insulation waterproof paint comprises the following components in parts by weight: 250 to 350 parts of silicone-acrylic emulsion, 300 to 350 parts of calcium powder, 300 to 350 parts of tap water, 8 to 12 parts of a blocking agent, 25 to 35 parts of a film forming aid, 2 to 5 parts of a dispersing agent, 1 to3 parts of a preservative, 2 to 4 parts of a defoaming agent and 2 to 4 parts of a thickening agent. The reflective heat insulation waterproof paint has heat insulation, antirust, anticorrosion and waterproof effect. The preparation method of the reflective heat insulation waterproof paint has the characteristics of simplicity and environment protection.

Description

technical field [0001] The invention relates to the field of waterproof coatings, in particular to a reflective heat-insulating waterproof paint, and also to a preparation method of the reflective heat-insulating waterproof paint. Background technique [0002] At present, among the waterproof coatings used in construction projects in my country, traditional asphalt waterproof coatings have faded out of the market due to poor performance, and PU waterproof coatings, rubber-modified bitumen waterproof coatings, and water-based acrylic waterproof coatings have been widely used. However, the first two waterproof coatings are not easy to be used for outdoor waterproofing alone, because the PU waterproof coating composed of TDI, MDI and polyether has poor weather resistance and is easily oxidized and turned yellow and powdered under ultraviolet radiation. , and the toxicity of the free monomers in the coating is high, which will cause harm to the human body and pollute the environ...

Problems solved by technology

However, the first two waterproof coatings are not easy to be used for outdoor waterproofing alone, because the PU waterproof coating composed of TDI, MDI and polyether has poor weather resistance and is easily oxidized and turned yellow and powdered under ultraviolet radiation. , and the toxicity of the free monomers in the coating is high, which will cause harm to the human body and pollute the environment; among the rubber-modified asphalt waterproof coatings, solvent-based waterproof coatings are gradually eliminated due to pollution to the environment, water-emulsion waterproof coatings In terms of mechanical properties, waterproof performance, and weather resistance and durability, they are not good enough and cannot be used in high-grade building waterproof projects; and the above two kinds of coating films are dark in color, absorb heat from solar radiation, and the coating temperature is high. Conduction, convection, and radiation cause the heat island effect in the surrounding environment and the temperature rise inside the building
