Description
Technical Field
The invention relates to the field of building coatings, in particular to a reflective heat-insulation stone-like coating base material.
Background
The stone-like coating is a new product type which is very popular in the building coating industry in recent years, and the product takes a physical and chemical colloid technology and a surface treatment technology as theoretical bases; various colloidal stone-like particles with different sizes and colors are uniformly and stably suspended and dispersed in the water-based emulsion coating, and the pattern effect of the finished granite-like stone can reach the extent of being fake and unreal through one-step construction and forming.
For example, Chinese patent publication No. CN103849280A discloses 'a preparation method of an ultra-stable high weather-resistant water-in-water granite imitation multicolor paint'; chinese patent publication No. CN103319969A discloses an environment-friendly water-in-water multicolor paint and a preparation method thereof. The technical development and application of the stone-like coating are mature day by day, but the stone-like coating is still like common latex in the aspect of energy saving and has no reflective heat insulation function.
At present, porous low-barrier heat insulation materials such as asbestos cloth, glass wool, foam plastics and the like are adopted for partial heat insulation, and the materials can only slow down but cannot block the transfer of heat energy. In daytime, solar energy continuously enters the space and the structure in a room or a container through a roof, a wall or a container wall, and once heat energy is transmitted, the heat energy is trapped in the space and the structure even if the outdoor temperature is reduced.
The heat insulation coating is typically used on the outer wall surface of a building and an outdoor large storage tank, and the common wall surface heat insulation technologies at home and abroad are as follows: the external-hanging external heat-insulation polystyrene board and the wall body are formed by one-step pouring and the polystyrene particle heat-insulation mortar external wall is heat-insulation, and the heat resistance is used as a heat-insulation means, so that the effect is good, the influence on the load bearing, the external decoration and the like of the building is large, and the construction cost is greatly increased.
The existing popular heat insulation coating is different from a porous low-barrier heat insulation material, and usually adopts a reflective heat insulation material, namely absorbed heat can be radiated in a heat radiation mode to cool the indoor space, and meanwhile, the reflective heat insulation material can reduce the influence of heat radiation on the outer wall of a building or the outer wall of a container, so that the method is a method for fundamentally solving the heat insulation and heat preservation of the wall or the container. However, the existing reflective heat-insulating material has poor stability, insufficient construction performance and heat-insulating effect and no elasticity, cannot adapt to the change of thermal expansion and cold contraction of a wall body or a container wall, and is easy to crack.

The potassium hexatitanate whisker powder and the potassium hexatitanate whisker sand are dispersed in the coating, have extremely high infrared reflection and diffuse reflection, and meanwhile, the modified ultra-white silica powder serving as the filler also has high reflection, small expansion coefficient, high hardness, good acid-base resistance and weather resistance, and can improve the tensile strength of the coating, so that the prepared coating has good heat insulation effect, high strength and good elasticity, and is not easy to generate cracks due to thermal expansion and cold contraction.
