Acrylic resin containing amphipathic lateral chain, and preparation and use thereof

Abstract

The invention relates to acrylic resin containing amphiphilic lateral chains, a preparation method thereof and application of the acrylic resin containing the amphiphilic lateral chains. The general structural formula of the acrylic resin containing the amphiphilic lateral chains is as shown in a figure 1. The preparation method comprises the following steps: (1) dichloromethane, tetraethylene glycol and triethylamine are added, acryloyl chloride is slowly dripped into the mixture under the protection of nitrogen, and the mixture is subjected to temperature rise and stirring; (2) ester obtained in the step (1) is dissolved in anhydrous dichloromethane, dipped with acyl fluoride containing perfluor polyether chains, and stirred at a temperature of 80 DEG C below zero and 25 DEG C; and (3) 100 to 150 millimeters of tetrahydrofuran and 800 to 900 milligrams of initiator are added, and the mixture is subjected to temperature rise to between 60 and 80 DEG C, added with 15 to 20 grams of methacrylic ester, 12 to 15 grams of glycidyl methacrylate and 15 to 25 grams of acrylic acid derivatives under the protection of the nitrogen, stirred, subjected to temperature rise to between 65 and 80 DEG C, maintained at a constant temperature for 48 to 72 hours to obtain the acrylic resin containing the amphiphilic lateral chains. The resin not only can be taken as a film former of marine antifouling coating but also has nontoxic and eco-friendly performance.

Description

technical field [0001] The invention belongs to the field of functional resins used in marine antifouling coatings, and in particular relates to an acrylic resin containing amphiphilic side chains and a preparation method and application thereof. Background technique [0002] As we all know, marine organisms attach to the bottom of the ship, increasing navigation resistance, reducing speed, and increasing fuel consumption during transportation; attaching to the inner wall of seawater cooling pipes will cause pipeline blockage, which will lead to major accidents; attaching to other submarine engineering structures will also cause Many adverse effects. All of these will bring huge economic losses to human beings. The traditional marine antifouling method is to use a large amount of toxic copper oxide and organotin compounds. These toxic paints or varnishes are highly antifouling and have been proven to be effective in preventing the hazards of marine fouling organisms. Howe...

Problems solved by technology

my country is a big shipping country, but the development of antifouling coatings or paints is relatively late. Compared with foreign countries, there is a big gap, especially at present, most of the antifouling agents on the market are monopolized by foreign coating companies.
