Problems solved by technology

Therefore, the effect of antifouling chemicals decreases, and the surface of the coating film becomes uneven, so the effect of preventing marine organisms and other organisms from adhering is significantly reduced.

Embodiment 1

[0151] 15 parts of an organic solvent (trade name: SOLVESSO 100, manufactured by ExxonMobil Chemical Co., Ltd.) was charged into a reaction container equipped with a stirrer, a temperature regulator, and a dripping device, and the temperature was raised to 130° C. while stirring. Next, polymerization including Step 1 and Step 2 was performed as follows.

[0152]

[0153] Then, the monomer mixture (M1) containing the following raw material was dripped over 2 hours, and the copolymerization reaction was further performed for 0.5 hours.

[0154] Composition of the monomer mixture (M1):

[0155] Macromonomer (a3-1): 15 parts,

[0156] n-BA: 20 parts,

[0157] MAA: 7 servings,

[0158] Tert-butyl peroxy 2-ethylhexanoate (PERBUTYL O, manufactured by NOF Corporation): 3 parts.

[0159]

[0160] Next, a monomer mixture (M2) containing the following raw materials was added dropwise over 3 hours, and a copolymerization reaction was further performed for 0.5 hours.

Embodiment 2～15、 comparative example 1、2

[0172] Except having made it into the input-amount shown in Table 3, it carried out similarly to Example 1, and obtained the resin composition P2-P17 for vinyl polymer A2-A17 and water-based antifouling paint. Table 3 shows the evaluation results.

[0173] In Comparative Example 1 in which no radical polymerizable group-containing macromonomer (a3) ​​was used in the monomer mixtures (M1) and (M2), the obtained vinyl polymer was a random copolymer. Therefore, The hardness and water resistance of the coating film containing this vinyl type polymer are insufficient. On the other hand, in Examples 1 to 15, coating films having excellent water resistance and sufficient hardness were obtained.

[0174] In Comparative Example 2 in which the divalent metal-containing ethylenically unsaturated monomer (a2) was not used, the degree of consumption of the coating film was insufficient, and sufficient antifouling performance was not obtained. On the other hand, in Examples 1 to 15, coati...

Abstract

Provided is a method for producing a vinyl polymer comprising step (1) for polymerization of a monomer mixture (M1) comprising a carboxyl group-containing ethylenic unsaturated monomer (a1) and step (2) for polymerization of a monomer mixture (M2) comprising a divalent metal-containing ethylenic unsaturated monomer (a2), and in the method for producing a vinyl polymer, the monomer mixture (M1) and / or the monomer mixture (M2) comprise a macromonomer (a3) having radical polymerizable groups, and either the monomer mixture (M2) is added to the polymerization reaction solution after step (1) and then step (2) is performed, or the monomer mixture (M1) is added to the polymerization reaction solution after step (2) and then step (1) is performed.

Description

technical field [0001] The present invention relates to a resin composition for water-based antifouling paints having antifouling properties. Furthermore, it also relates to the manufacturing method of the vinyl type polymer suitable for obtaining the resin composition for water-based antifouling paints. Background technique [0002] Antifouling paint is a paint that is applied to underwater structures, fishing nets, ship bottoms, etc. for the purpose of preventing the adhesion of marine organisms and algae. The coating film obtained from the antifouling paint exhibits the antifouling effect through the dissolution of the antifouling chemical ingredients contained in the paint in the sea. Various antifouling paints are known. For example, when a coating film obtained from a disintegrating antifouling paint using a rosin-based compound is immersed in the sea for a long time, the eluted components gradually decrease and the insoluble components gradually decrease. many. The...
