Sunlight heat-reflection, heat-insulation and heat-preservation sand-in-water colored environment-friendly coating and preparation method thereof

Abstract

The invention discloses sunlight heat-reflection, heat-insulation and heat-preservation sand-in-water colored environment-friendly coating and a preparation method thereof. The sand-in-water colored environment-friendly coating is formed through four stages including a colloidal solution, a gel solution, granulated basic paint and finished-product paint; a water-based acrylic copolymer dispersionbody is used as a main body; after the main body is naturally dried to form a paint film, the paint film has good weather resistance, anti-staining performance, waterproof performance, chemical resisting performance, self-cleaning performance, is safe and environmentally friendly and has a wide applicable range; a gel agent is added, so that the constructability, stirring performance, transportability, anti-settling performance, particle shredding resisting performance and whole storage stability of the coating are effectively improved; ceramic hollow microspheres are added into the coating sothat residual sunlight radiation energy which permeates into a wall body can be further separated; each ceramic hollow microsphere is a thin-wall single hollow sphere body, is similar with a double-layer glass effect and has heat-reflection, heat-insulation and heat-preservation effects, so that the heat-insulation and heat-preservation performance of the coating is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat-insulating and heat-insulating coatings for buildings, and particularly discloses a multi-color environmental protection coating with sand in water for solar heat reflection, heat-insulating and heat-insulating, and a preparation method thereof. Background technique [0002] Building energy conservation is one of the key points of my country's energy conservation work, and external wall insulation has become the main product of building energy conservation. For areas where thermal insulation is the main focus of thermal design, such as severe cold areas and cold areas, external wall insulation is not only reasonable, but also applicable, and has developed rapidly. [0003] The coating that can play the role of thermal insulation on the surface to be constructed is called thermal insulation coating, which can be divided into transparent thermal insulation coating and non-transparent thermal insulation...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned patented technology has the following problems: First, its production method is to prepare a protective colloid solution with a concentration of 5-10%, then prepare a white sand-containing base paint, then add color paste to the color according to the design requirements, and finally color The process of paint granulation is complicated, and the stirring and dispersing equipment used in the granulation leads to the uneven particle size during granulation, which affects the appearance of the coating film and the construction performance

Secondly, the paint only uses a small amount of reflective pigments to reflect its reflective and heat-insulating function, and cannot achieve a variety of colors. The sand used in the paint is ordinary white sand, which makes it effective in blocking residual solar radiation energy. Poor, unable to further block the residual solar radiant energy penetrating into the wall, greatly reducing the effect of coating reflection and heat insulation, and does not have the function of heat preservation
