Energy-saving and environment-friendly real stone type composite coating and preparation method and construction method thereof

Abstract

The invention discloses an energy-saving and environment-friendly real stone type composite coating which is prepared from a cover surface layer coating, a real stone paint middle layer coating and a prime coating. The prime coating is prepared from styrene-acrylic emulsion, water, titanium dioxide, special filler and auxiliary C. The real stone paint middle layer coating is prepared from synthesized resin emulsion, deionized water, functional material A, self-made functional color sand and auxiliary A. The cover surface layer coating is prepared from deionized water, synthesized resin emulsion, functional material B and auxiliary B. According to the composite coating layer, the nanometer functional materials are applied to the real stone paint middle layer coating and the cover surface layer coating, the reflection and thermal insulation effect of the nanometer functional materials and the decoration effect of natural stone of the real stone paint middle layer coating are organically and innovatively combined, the energy-saving and environment-friendly real stone type composite coating layer is ingeniously formed through a heat preservation layer formed according to the natural coating thickness of the real stone paint middle layer coating, energy can be saved by 40-50%, the indoor temperature can be decreased by 6-8 DEG C, and the remarkable thermal insulation and heat preservation effects are achieved. The invention further discloses a preparation method and construction method of the energy-saving and environment-friendly real stone type composite coating.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to an energy-saving and environment-friendly real stone-type combined paint, and also relates to its preparation method and construction method. Background technique [0002] As known in the industry, directly sticking or dry hanging such as marble, granite stone or other similar materials on the outer wall of the building can significantly play a decorative effect and a certain heat insulation effect. And on the exterior wall of the building, the energy-saving effect of the building is superior to that of the dry-hanging marble by dry-hanging the thermal insulation board in a dry-hanging manner. This can be achieved by not limited to Chinese patent CN101725311A (perlite fiber composite fireproof insulation board), CN2352333Y (composite thermal insulation board), CN2825784Y (external wall thermal insulation board), CN20138361Y (exterior wall thermal...

Problems solved by technology

[0004] Further, in order to improve the decorative performance, water-based colorful imitation stone paints and real stone paints or texture paints with natural stone decorative textures have begun or are widely used in the market, and there is a trend of intensification, and corresponding patents have also appeared at the same time. To enumerate such as: Invention Patent Application Publication No. CN102277045A recommends "a kind of water-based imitation stone colorful coating and preparation method thereof", and this patent application scheme has the said coating appearance layer rich in the 0034th column of the description, strong three-dimensional effect and has The advantages of natural stone patterns, however, because the film-forming aid uses an aqueous solution of alcohol ester and butyl glycol ether in a weight ratio of 1:1, it loses safety and environmental protection, because butyl glycol is harmful to the human body. It is a health hazard and can be fatal if inhaled. In addition, it has been shown in animal experiments that it will damage the reproductive system, so be cautious about the production and use of paints containing this ingredient; Although ZL201010533680.5 (a combined coating used in a textured coating layer) overcomes the above-mentioned shortcomings, it is still a shortcoming that it does not have the effect of heat preservation and energy saving
