Abstract

The invention relates to a modified acrylic resin varnish for anti-corrosion paint, belonging to the field of applied chemistry. The invention overcomes the shortages that the traditional varnish commonly has short preserving time, cannot effectively control the seepage speed of copper ions, cannot control the self-polishing speed and cannot prevent pollution for a long time. In the invention, the preparation process of the modified acrylic resin varnish is divided into two steps of: firstly, adding bimetal salt used as a catalyst to a certain amount of xylene and n-butyl alcohol solvent, and then adding ethylene oxide at certain temperature to finish polymerization reaction; secondly, adding a certain amount of xylene and n-butyl alcohol solvent to the reaction liquid again, and then dropwise adding methyl methacrylate, butyl acrylate, acrylic acid and initiator azodiisobutyronitrile at certain temperature, adding cupric oxide and oleic acid after finishing the polymerization reaction, and then refluxing and shunting so as to obtain the modified acrylic resin varnish. The invention is applied to pollution prevention of an underwater structure and has the characteristics of long varnish endurance, no cracks and self-polishing performance.

Description

Technical field: [0001] The invention belongs to the field of applied chemistry and relates to a modified acrylic resin varnish used for antifouling paint. Background technique: [0002] Ships and other underwater structures are prone to adhere to marine fouling organisms, which will slow down the ship's speed, waste fuel, and shorten the life of underwater structures. In order to prevent ships and underwater structures from attaching to fouling organisms, the common method is to paint Antifouling paint. At present, the varnishes used at home and abroad generally have the disadvantages of short storage time, inability to effectively control the seeping speed of copper ions, inability to control the self-polishing speed, and failure to achieve durable antifouling. Invention content: [0003] The purpose of the present invention is to provide a modified acrylic resin varnish for antifouling paint, which is used to solve the problem that marine fouling organisms are easily a...
