Combined paint

Abstract

The invention discloses combined paint. The combined paint comprises priming paint and finishing paint, and is characterized in that the priming paint is prepared from a priming paint component A anda priming paint component B, the priming paint component A is prepared from the following components by weight percent: 30 to 40 percent of epoxy resin, 30 to 40 percent of hollow glass microbeads, 1percent of an aerogel aid, and the balance of solvent; the priming paint component B is a polyamide curing agent; the finishing paint is prepared from a finishing paint component A and a finishing paint component B which are independently packaged and jointly used, the finishing paint component A is a paint main agent, the finishing paint component B is a film forming accelerant, and the finishingpaint component A is prepared from the following components by weight percent: 20 to 36 percent of modified silicone resin, 0.2 to 0.5 percent of an organic silicon flatting agent, and the balance ofnano silicon oxide; and the finishing paint component B is prepared from the following components by weight percent: 1 to 2 percent of a titanate coupling agent, 2 to 5 percent of polyethylene glycol, and the balance of alcohol solvent.

Description

technical field [0001] The present invention relates to a combined paint. Background technique [0002] At present, the surface of external walls and steel pipes is usually painted with epoxy primer + polyurethane topcoat, or with water-based one-component and two-component acrylic paint for environmental protection. These coating methods can only meet the general requirements. protection and decoration requirements, but these methods cannot meet the requirements of heat preservation and heat insulation for special occasions with heat preservation and heat insulation requirements. Contents of the invention [0003] The technical problem to be solved by this invention is to overcome the deficiencies in the prior art and provide a combination coating. The technical scheme provided by the invention is as follows: [0004] The invention provides a kind of combination coating, comprises primer and topcoat, and primer comprises primer A component and primer B component, and pri...
