Problems solved by technology

Due to the lack of one-component chlorinated rubber aluminum powder thick coating primer and asphalt anti-corrosion aluminum powder primer due to poor anti-corrosion effect and the suspicion of carcinogenicity of asphalt, the anti-corrosion coating now requires low surface treatment adaptability, environmental protection, long-term anti-corrosion, and curing time. to be short

Abstract

The invention relates to a preparation method of a marine coating emulsion, which comprise the following steps of: (1) respectively dissolving a 1631 surfactant and an OP (Polyoxyethylene Pctylphenol Ether) emulsifier with 50-55 DEG C of hot water according to the ratio of 3:7, and cooling; (2) pouring neoprene latex in an agitating tank, and agitating for 5-10 min while gradually adding the 1631 surfactant and the water solution according to the ratio of 5:5; (3) pouring the OP emulsification solution and the water solution into a chlorine partial emulsion according to the ratio of 3:7, and stirring for 3-5 min; and (4) pouring the chlorine partial emulsion into the neoprene mixture emulsion according to the ratio of 4:6, and stirring for 10 min while gradually pouring a defoamer. Because the hot water is used as an additive and no solvent is used, the preparation method has the advantages of environmental protection and no environmental pollution, and the construction harm of the traditional coating is eliminated.

Description

1. Technical Field [0001] The invention relates to a method for preparing a marine paint emulsion. 2. Background technology [0002] Anti-corrosion coating is to coat corrosion-resistant coating on the metal surface, after curing into a film, it has the functions of shielding, corrosion resistance and electrochemistry. Coating anti-corrosion coatings on metal surfaces is the most economical, effective, and most commonly used method of metal anti-corrosion. The anti-corrosion coating used on the metal of marine environment ships must have good adhesion and a certain mechanical strength. The cured coating can firmly adhere to the metal substrate and have a certain mechanical strength to ensure that it can withstand work The role of various forces under the conditions should also have the following special properties. (1) Salt spray resistance. Due to the strong electrolyte environment formed by sea water or salt spray in the ocean, the metal in this environment is easily ionized...
