[0060] (1) Preparation process of erosion type matrix resin A

[0061] Add part of the solvent and part of the monomer a1 according to the formula amount into a four-necked bottle equipped with a stirring device, a condenser, a dropping funnel, and a thermometer, raise the temperature to 90-115°C, and mix acrylic acid or methacrylic acid and the remaining mono Mix monomer a1, monomer a2, monomer a3 and part of the initiator according to the formula ratio, and add them all dropwise into the four-necked bottle, add dropwise for 3.0-3.5 hours, keep warm for 1.0-1.5 hours, and then add the remaining initiator and After adding the solvent, keep it warm for 2.0 to 2.5 hours, cool down and discharge the material, and prepare the erosion-type matrix resin A.

[0062] In the process of preparing the erosion-type matrix resin A, the weight ratio of monomer a1 added twice is 1:1-10.

Embodiment 1

[0068] Example 1: Erosion-type matrix resin A1

[0069] Add 25 parts of propylene glycol methyl ether, 85 parts of xylene and 5 parts of ethyl acrylate into a four-necked flask equipped with a stirring device, a condenser, a dropping funnel, and a thermometer, and stir and heat to 105°C. From the dropping funnel, add 15 parts of acrylic acid, 15 parts of ethyl acrylate, 40 parts of methyl methacrylate, 15 parts of ethyl methacrylate, 10 parts of methoxyethyl acrylate, 2.5 parts of azobisisobutyl The mixed liquid composed of nitrile was 3 hours. After adding all the mixed liquid dropwise, keep it warm for 1.0 hour, then add 0.5 parts of azobisisobutyronitrile and 10 parts of xylene, keep it for another 2.5 hours, cool down and discharge the material to obtain the erosion matrix resin A1.

Abstract

The invention discloses a corrosion type marine anti-fouling paint, a corrosion type matrix resin and a preparation method. The paint comprises the following basic components in parts by weight: 10-50parts of corrosion-type matrix resin (A), 15-55 parts of a composite anti-fouling agent (B), 3-50 parts of a pigment filler (C), 1-6 parts of an assistant (D) and 3-35 parts of a solvent (E). Hydrogen ions (H<+>) electrolyzed from carboxylic acid groups contained in matrix resin in the anti-fouling paint and hydroxide ions (OH<->) in seawater are slowly dissolved, so that an anti-fouling agent inthe anti-fouling paint is slowly dissolved in the seawater, the anti-fouling purpose is achieved, the anti-fouling paint has 18-24 anti-fouling period effects, and the requirements of underwater facilities in the sea on medium-short-term-effect and low-cost anti-fouling paint can be met; and the cost is low and easy to control.

Description

technical field [0001] The invention relates to the field of marine antifouling coatings, in particular to a dissolution type marine antifouling coating, a dissolution type matrix resin and a preparation method. Background technique [0002] Antifouling paint is a special marine paint that is applied on the surface of offshore underwater facilities to prevent marine organisms from fouling and to keep the surface of the facility smooth and clean. With the enhancement of human environmental awareness and the continuous development of marine coating technology, after many product changes, Wuxi self-polishing antifouling coatings have gradually become the mainstream products in the market, mainly used for antifouling protection of underwater facilities in the sea. However, in some cases, such as small and medium-sized fishing boats, the construction method is mostly roller coating. The thickness of the paint film in a single layer of roller coating is very thin, and most of the ...
