Novel aqueous insulation paint

Abstract

The invention relates to a water thermal-insulation paint used in constructions, comprising the following raw materials: ceramic hollow micro bead, emulsion, latent solvent, filler, pigment, wetting agent, dispersing agent, thickening agent, antifoam agent, germicide and water. The ceramic hollow micro bead, which is added in the paint, can form a paper-thin enclosed hollow cavity layer when coated on the surface of a building, thereby effectively preventing thermal conduction and thermal radiation.

Description

technical field [0001] The present invention designs the field of building materials, especially the field of water-based thermal insulation coatings for houses Background technique [0002] In recent years, under the advocacy and guidance of the country to establish a conservation-oriented society, various industries are researching new methods and new processes for energy conservation. Due to the simple coating construction process, seamless construction can be achieved and the existence of thermal bridges can be reduced. The research on thermal insulation coatings has become a hotspot. [0003] Thermal insulation coatings are generally divided into two categories: 1. Barrier type thermal insulation coating is a coating that achieves heat insulation through the high thermal resistance of the coating itself. It is a thick film coating. The coating is applied to a certain thickness during construction, generally 5-20mm. After being fully dried and cured, the thermal conduc...

However, the production time of this kind of coating is long, and the metal coating is greatly affected by the environment. Dust and acid rain will have a huge impact on the performance of this coating.

The invention patent with the publication number CN1986664A discloses a kind of insulating coating with hollow glass microspheres as additives, which can reduce the surface of various objects, reduce their surface temperature and internal temperature, thereby improving the working environment and achieving the purpose of saving energy and reducing consumption. However, the existing hollow glass microspheres have poor wettability with water, are difficult to disperse in the paint and are easy to segregate during storage. After coating, they are not firmly adhered to the base layer and have poor durability.
