Problems solved by technology

The disadvantage of this polyacrylic acid metal salt resin is that basic copper hydroxide or basic zinc hydroxide or basic small molecule organic acid copper salt or basic small molecule organic acid zinc salt are used in the preparation, which is easy to cause in the prepolymer The hydrolysis of the ester group and then gelation will cause the storage stability of the resin and antifouling coating to deteriorate, which will affect the production and use of antifouling coating

Embodiment

[0014] Example: refer to figure 1 , the specific implementation is as follows:

[0015] 1. Preparation of mixed organic acid copper or organic acid zinc

[0016] When preparing by mixing organic acid copper or zinc, use newly prepared copper hydroxide or zinc hydroxide to react with acetic acid and small molecule organic acid in equimolar ratio. The small molecule organic acid used in the above reaction is acetic acid or chloroacetic acid or cyanoacetic acid or hexanoic acid or isocaproic acid or heptanoic acid or isoheptanoic acid or a combination thereof.

[0017] Preparation of copper acetate chloroacetate:

[0018] During preparation, weigh 24.96g (0.1mol) of hydrated copper sulfate, dissolve it in 75ml of water, slowly add a saturated solution containing 8g (0.2mol) of sodium hydroxide under stirring, filter, wash the filter cake with water, and obtain newly prepared hydrogen Copper oxide.

[0019] Add 100ml of water to the newly prepared copper hydroxide, and slowly ...

Abstract

The invention discloses a preparation method of copper / zinc-containing metal polyacrylate resin, which comprises the following steps: preparing copper / zinc hydroxide; preparing copper acetate / chloroacetate; preparing a carboxyl-containing polyacrylic acid prepolymer; and preparing the final product. The invention also discloses application of the copper / zinc-containing metal polyacrylate resin in marine anti-fouling paint. The copper / zinc-containing metal polyacrylate resin has the following advantages: no alkaline reaction agent is used in the preparation process, gelation can not be easily caused, and the copper / zinc-containing metal polyacrylate resin for marine anti-fouling paint enhances the stability of the anti-fouling paint.

Description

technical field [0001] The invention relates to a preparation method and application of polyacrylic acid metal salt resin, in particular to a preparation method and application of copper or zinc-containing polyacrylic acid metal salt resin. Background technique [0002] Metallic resins have a wide range of applications, and polyacrylic acid metal salt resins for antifouling coatings are one of them. U.S. Patent No. 7,435,771 has reported a kind of polyacrylic acid copper or zinc salt resin, and it is to obtain the side chain containing carboxyl prepolymer by acrylic acid or methacrylic acid and acrylic acid ester or methacrylic acid ester copolymerization earlier, then with copper hydroxide, The small molecule organic acid or basic small molecule organic acid copper salt is reacted and can be used to prepare marine antifouling paint. The disadvantage of this polyacrylic acid metal salt resin is that basic copper hydroxide or basic zinc hydroxide or basic small molecule orga...
