Abstract

The invention discloses a graphene insulating light coating which is prepared from the following components in parts by weight: 7-10 parts of calcium carbonate, 3-5 parts of talcum powder, 3-5 parts of gypsum powder, 15-25 parts of titanium dioxide, 0.5-2 parts of fumed silica, 2-4 parts of graphene powder, 0.1-1 part of a surfactant, 0.01-0.1 part of a defoamer, 3-8 parts of a film forming agent,0.02-0.1 part of an antibacterial and mildew resistant agent and 30-90 parts of water. The novel graphene insulating light coating is prepared by taking the calcium carbonate, the talcum powder, thegypsum powder, the titanium dioxide, the fumed silica and graphene as raw materials, matched with other auxiliary materials. For the graphene insulating light coating provided by the invention, the graphene can form a nanometer reticular framework in the coating, so that the coating has the firmness and firm skeleton, and the insulating coating is firmer in adhesion, more has the super-durabilityand is better in heat insulation performance; and the coating is light in quality of own selected materials and convenient in conveying and coating.

Description

technical field [0001] The present invention relates to a kind of coating, more specifically, relate to a kind of graphene heat-insulating lightweight coating and its preparation method and application. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] At present, known coatings are widely used in construction, vehicles, military, decoration, and shipbuilding industries, and are closely related to people's lives. However, most coatings themselves have no heat insulation function and need to be coated with thicker coatings, which is inconvenient for coating and transportation. . Contents of the inventi...
