Ceramic crystal powdery coating and preparation method and construction process thereof

Abstract

The invention discloses a ceramic crystal powdery coating, a preparation method and a construction process, and belongs to the technical field of coatings. The powdery coating is prepared from, by weight, 22-28 parts of ceramic crystal micro-powder, 15-20 parts of mica powder, 6-9 parts of tourmaline powder, 50-70 parts of film-forming substances and 6-12 parts of auxiliary agent; the particle size of the ceramic crystal micro-powder is 25-60 microns, the firing temperature is greater than or equal to 1,600 DEG C, the particle size of the mica powder is 150-180 mesh, and the particle size of the tourmaline powder is 200-250 mesh. According to the powdery coating, ceramic crystals serve as a main material in cooperation with other powdery filler, good air lamination systems are formed amongparticles in the coating and in the ceramic crystals, an air layer has a good heat insulation and preservation effect, the reflectivity to sunlight radiation heat is high, the thermal conductivity islow, the film coating thickness of the powdery coating is only 0.35 mm, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a ceramic crystal powder coating, a preparation method and a construction process thereof. Background technique [0002] In recent years, my country's coating technology has continued to develop, and energy-saving and environmentally friendly heat-insulating coating products continue to emerge. With the development of the national economy and modern science and technology, people have increasingly higher requirements for the comfort of the housing environment. The hot summer and the cold winter have greatly increased the utilization rate of air conditioners, heating and other electrical equipment, bringing energy-saving and environmentally friendly coating products. There are new opportunities and challenges. However, most of the existing house decoration coatings have poor heat insulation effect and high thermal conductivity. The temperature difference between the room and the...

Problems solved by technology

However, most of the existing house decoration coatings have poor heat insulation effect and high thermal conductivity. The temperature difference between the room and the roof is high, and the external cold air is easy to invade, and the indoor heat escapes outwards, resulting in poor indoor heat preservation and heat insulation. It is often necessary to apply a thicker coating layer to achieve the ideal heat insulation effect, and the reflectivity of the heat insulation coating is not high

On the other hand, the existing heat-insulating coatings are prone to shedding and water leakage, which can only play a simple covering role, but do not have the effect of protecting the wall surface. short

For example, the Chinese patent announced a heat-reflective and heat-insulating baking varnish coating, in which heat-insulating powder and infrared reflective pigments are added to the raw materials, which has a good heat-insulating effect and solves the temperature difference between indoor and outdoor to a certain extent. However, the effect of heat insulation and heat preservation is not significant, the temperature difference of heat insulation is only 7°C, the thermal conductivity of the material is high, the reflectivity of the paint is not high, and the economic benefit is low; on the other hand, the The durability of the paint is poor and it is prone to peeling off

How to provide a powder coating with high reflectivity, low thermal conductivity and remarkable heat insulation effect has become a new problem faced by the coatings industry
