Waterproof thermal insulation building coating and preparation method thereof

Abstract

The invention discloses a waterproof thermal insulation building coating and a preparation method thereof. The waterproof thermal insulation building coating is prepared from the following componentsby mass ratio: 20-25 parts water-based silicone acrylic emulsion, 16-20 parts water-based fluorocarbon emulsion, 10-12 parts of silica aerogel, 5-8 parts expanded perlite, 6-8 parts of nano ceramic particles, 10-14 parts of floating beads, 5-7 parts of polyvinylpyrrolidone, 15-20 parts of auxiliary filler and 25-28 parts of deionized water. The waterproof thermal insulation building coating can improve the high temperature resistance, thermal insulation performance and waterproof performance of the prepared building coating by using the compositions of the water-based silicone acrylic emulsion, the water-based fluorocarbon emulsion, the nano ceramic particles, the silica aerogel and the like in the components, the flexibility, weatherability, wear resistance and adhesion of the building coating can be further improved, polyvinylpyrrolidone in the compositions can improve the ductility and fluidity of the building coating, and waterproof and thermal insulation effects can be achieved without thick coating.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a waterproof thermal insulation architectural coating and a preparation method thereof. Background technique [0002] The earth is being irradiated by the sun all the time. The huge energy provides the necessary conditions for human survival and life. However, the strong radiation of the sun also brings inconvenience to people's life. The heating of construction plants and houses leads to Extensive use of air-conditioning consumes already scarce electric energy. my country's per capita resources are in short supply, and energy shortage is the main contradiction restricting my country's economic development. With the improvement of living standards, people pay more and more attention to the comfort of the living environment, and the requirements for buildings continue to increase. Energy-saving buildings are an effective way to improve the efficiency of building energy use. ...

Problems solved by technology

[0003] Architectural coatings are coated on the surface of the building to be protected and can form a continuous film firmly attached to the object to be coated. The existing architectural coatings have a relatively single function, and there are certain defects in the functions of waterproofing, heat preservation and heat insulation. At the same time, they are easy to Problems of pulverization and poor fluidity occur, therefore, the present invention proposes a waterproof thermal insulation architectural coating and a preparation method thereof to solve the deficiencies in the prior art
