Abstract
The invention discloses a reflective heat-insulation waterproof coating and a preparation method and application thereof. The reflective heat-insulation waterproof coating comprises a material A and amaterial B. The material A is a liquid material and is mainly prepared from, by weight, 98.5-99 parts of silicone acrylic emulsion, 0.1-0.15 parts of multifunctional auxiliaries, 0.1-0.4 parts of a defoaming agent and 0.1-1 part of an anti-freezing agent. The material B is a powder material and is mainly prepared from the following raw materials in parts by weight: 25-45 parts of Portland cement,10-15 parts of titanium dioxide, 5-20 parts of ground calcium carbonate, 5-10 parts of a thermal insulation material and 20-40 parts of quartz sand. The polymer waterproof coating with reflection andheat insulation performances has ultraviolet light resistance, reflection and heat insulation performances and a waterproof function in an exposed environment. The waterproof coating has the characteristics of excellent weather resistance, strong ultraviolet resistance, strong stain resistance, high stability and high mechanical property strength. The waterproof coating is simple to prepare, convenient to construct, green, environment-friendly and pollution-free, and reduces the labor cost.
Description
technical field [0001] The invention relates to a waterproof material for building, in particular to a waterproof coating with reflection and heat insulation performance and a preparation method thereof. Background technique [0002] With the development of society and the passage of time, people's residences and other functional buildings will more or less leak due to the aging of concrete, structural damage, and settlement displacement. The solution we usually adopt is to use waterproof materials to repair. Existing water-based waterproof coatings mainly contain two kinds of polymer emulsion waterproof coatings and polymer cement waterproof coatings. Polymer emulsion waterproof coating is mainly made of acrylate homopolymer emulsion, styrene-acrylate copolymer emulsion, ethylene-vinyl acetate copolymer emulsion and vinyl chloride-butadiene copolymer emulsion, etc., and is made by adding fillers such as calcium carbonate and titanium dioxide The single-component waterproo...
