Polyaspartic industrial coating and its preparation method and application

Abstract

The invention discloses a polyaspartate industrial coating material and a preparation method and application thereof. The polyaspartate industrial coating material consists of a main agent and a curing agent, wherein the weight part ratio of the main agent to the curing agent is (100: 25) to (100: 50). The main agent and the curing agent are matched with materials, such as pigments of various colors, a dispersing agent, filler, a defoamer, a rust prevention material, a leveling agent, a sagging prevention assistant and the like, through polyaspartate resin and then are matched with isocyanate, a catalyst, a diluent and the like, so as to prepare a series of aspartate industrial coating materials. The series of coating materials can be coated on the surfaces of various steel materials under the condition of natural drying or low-temperature baking, and the thickness of a once-coated film is 20-50 microns. The coating material is used for overcoming the defects of poor corrosion preventing and weather resisting effects and short protection time of the general industrial protective coating materials, and particularly, the corrosion preventing and weather resisting effects and protection time of the coating material are improved obviously on liquid media of salt mist resisting, acid resisting, alkali resisting and the like. The coating material can be widely applied to the coating of products, such as steel structures, parts made from steel materials, pipelines, oil tanks and the like.

Description

technical field [0001] The invention belongs to the technical field of coating protection for steel substrate products, and relates to a polyaspartic resin coating, more specifically to a polyaspartic industrial coating and its preparation method and application. Background technique [0002] From 2007 to 2012, China's industrial paint demand and output increased from 1.82 million tons in 2007 to 4.28 million tons in 2012, while our industrial paint supply increased from 968,000 tons in 2007 to 2,345,000 tons in 2012, Although our supply has greatly increased, there is still a certain distance from the demand. A large part of the reason why the supply is far less than the demand is that customers have to use imported products because they cannot meet their requirements on paint environmental protection and paint film performance. The use of imported products puts a lot of pressure on profit margins, and at the same time greatly reduces the company's international competitiv...
