Abstract

The invention provides a preparation method of acrylic resin containing organic zinc or copper. The method comprises the following steps: (1) making acrylic acid, zinc hydroxide / copper hydroxide, and sodium benzoate carry out reactions for 1 to 2 hours at a temperature of 78 to 82 DEG C, then heating the reaction product, dehydrating the reaction product until no water is distilled out to obtain an organic zinc / copper acrylate solution (A); (2) evenly mixing methyl methacrylate, butyl acrylate, azodiisobutyronitrile, and tert-dodecyl mercaptan, dropwise adding the solution (A) within 2 to 2.5 hours at a temperature of 74 to 76 DEG C under a rotation speed of 98 to 102 r / min, and maintaining the temperature to carry out polymerization reactions for 1 to 1.5 hours to obtain a acrylic resin solution containing organic zinc / copper, wherein the mole ratio of methyl methacrylate to butyl acrylate to acrylic acid, which is taken as the raw material in the step (1), is (0.8-0.9):(0.4-0.6):1. The preparation method has the advantages of simple technology, low reaction temperature, short time, little energy consumption, and easy control.

Description

technical field

[0001] The invention relates to a preparation method of an organic zinc or copper-containing acrylic resin. Background technique

[0002] Animals, algae, bacteria and fungi in the ocean can adhere to the bottom of ships, offshore platforms and other facilities submerged in seawater for a long time, forming marine biofouling, causing equipment damage or excessive energy consumption. Tin-free self-polishing antifouling coatings can effectively prevent marine biofouling, and its film-forming material is mainly acrylic resin containing zinc or copper. For example, patent document CN1544488A describes a kind of synthetic method of this type of resin, at first synthesize the basic salt of zinc or copper of organic acid, then synthesize the acrylic resin containing carboxyl group, make the basic salt of zinc or copper of organic acid and The carboxyl-containing acrylic resin reacts to generate zinc acrylate, but its disadvantage is that the synthesis process is com...
