Problems solved by technology

In my country, although there are paints on the surface of large-scale various structural projects, such as bridges and buildings, due to the low solid content of fluorocarbon coatings with good weather resistance, they will pollute the environment and aggravate the formation of smog. Low content, unsatisfactory weather resistance, resulting in shortened maintenance time of coatings, aggravated environmental pollution, and increased economic costs

Abstract

The invention relates to a coating with high solid content and high fluorine content and a preparation process thereof. The coating comprises a component I finished product and a component II finished product, wherein the component I finished product and the component II finished product comprise the following components shown in the description in percentages by mass. The coating provided by the invention has double components, can be self-dried at normal temperature, and is high in solid content and low in VOC emission, so that the environmental pollution is reduced and generation of haze is reduced; the coating is high in fluorine content and better in weather resistance, the service life of the coating can be effectively prolonged, large-area maintenance within a short time is reduced, the maintenance cost is lowered, and the economical benefit is improved. The coating provided by the invention can be used for decoration of structures such as a concrete structure, a steel structure and aluminum plastic, an outer surface coating of a protecting coating, and can be matched with an acrylic polyurethane coating, epoxy coating and etc.

Description

technical field [0001] The invention belongs to the technical field of two-component fluorocarbon coatings, in particular to a coating with high solid content and high fluorine content that can be dried at room temperature and its preparation process. Background technique [0002] With the rapid development of my country's economic construction and national economy, various steel structures, concrete structures, aluminum-plastic structures, etc. are more and more applied to bridges, buildings, ports, transportation and other industrial and civil projects; Corrosion problems and decorative problems on these structures. In my country, although there are paints on the surface of large-scale various structural projects, such as bridges and buildings, due to the low solid content of fluorocarbon coatings with good weather resistance, they will pollute the environment and aggravate the formation of smog. Low content, unsatisfactory weather resistance, shorten the maintenance time o...
