Abstract

The invention discloses a high solid epoxy paint formula and a preparation process as well as application thereof. The formula comprises main agents and a curing agent, wherein the main agents comprise an epoxy resin matrix, a diluting agent, pigment and filler and auxiliary agents. The invention also discloses the preparation process of the paint. The preparation process comprises the steps of preparing, grinding, mixing and the like. The high solid epoxy paint is widely applied of petroleum drilling equipment and ship industry. The high solid epoxy paint is of high solid, low viscosity and thick coating, meanwhile has excellent surface adaptability and is extremely suitable for the current environmental protection requirement; in addition, the high solid epoxy paint can be widely applied to the petroleum drilling equipment and the ship industry, and has the characteristics of high energy saving efficiency, high construction performance, high filming quality, no strict requirements on processing of a metal surface, greatly reduced construction cost and the like.

Description

technical field [0001] The invention belongs to the technical field of coating production, and in particular relates to a high-solid epoxy coating formula and its preparation process and application. Background technique [0002] With the increasing awareness of human environmental protection, the requirements for the content of volatile solvents in coatings will become more and more stringent. Although there are still developments in water-based coatings, powder coatings, and radiation-cured coatings, high-solid coatings containing certain solvents and Its unique characteristics determine its irreplaceable status. [0003] At present, although the proportion of environmentally friendly products in my country's coating industry continues to rise, ordinary coatings with high VOC (volatile organic substances) still account for nearly half of the share, and most of the manufacturers of high-solid coatings are wholly foreign-owned or Sino-foreign joint ventures . After the deve...
