Embodiment Construction

[0016] Shown according to the technical scheme, the proportioning by weight of the high hydrolysis rate antifouling coating is as follows:

[0017] Comb-type acrylic resin 15-18, natural rosin or rosin soap 5-10, cuprous oxide 38-42, copper pyrithione 5, zineb 5, polyamide wax 1, zinc oxide 4-8, talcum powder 1- 5. Iron red 5-10, xylene 5-17.

[0018] The above-mentioned comb-shaped acrylic resin adopts the comb-shaped acrylic resin disclosed in Chinese patent CN 102532559 A. The main chain of the comb-shaped acrylic resin is a structural unit of acrylic, and the side chain is a structural unit of degradable polyester. The polymerization degree of the main chain is about The degree of polymerization of the side chain polyester is about 1 to 30, and the static hydrolysis rate of the comb-type acrylic resin is 2 to 10 mg / (cm 2 ·year). Rosin soap is either rosin calcium soap or rosin zinc soap. It is suggested that rosin calcium soap can be replaced by lime rosin. Cuprous oxid...

Abstract

The invention relates to a preparation method of an antifouling paint with a high hydrolysis rate. The preparation method comprises the following steps: putting 15-18 parts by weight of combtype acrylic resin, 5-10 parts by weight of natural rosin or a rosin soap, 5-10 parts by weight of iron oxide red, 4-8 parts by weight of zinc oxide and 1-5 parts by weight of talcum powder together into 5-17 parts by weight of dimethylbenzene to be dissolved and dispersed; after fully dissolving, transferring the mixture obtained from the former step to a grinder to be ground to the grain size being less than 80 microns; then, transferring the ground material from the former step to a dispersing machine and adding 38-42 parts by weight of cuprous oxide, 5 parts of copper pyrithione and 5 parts of zineb to be dispersed and stirred; after uniformly dispersing and stirring, transferring the mixture from the former step to the grinder to be ground to the grain size being less than 100 microns; then transferring the ground material from the former step to the dispersing machine and adding 1 part by weight of polyamide wax to be dispersed and stirred; and after uniformly dispersing and stirring, preparing the antifouling paint with the high hydrolysis rate, wherein the copper ion exudation rate under a static condition can reach 30-40 microgram / (cm<2>.d), and the antifouling paint has an antifouling period of two years.

Description

technical field [0001] The invention belongs to the technical field of antifouling coatings, in particular the invention relates to a preparation method of high hydrolysis rate antifouling coatings. Background technique [0002] There are many patented technologies on antifouling coatings, such as abrasive antifouling coatings, hydrolytic antifouling coatings, self-polishing antifouling coatings, low surface energy antifouling coatings and bionic antifouling coatings, etc. These antifouling coatings are mostly used in ships. Its antifouling effect has a certain dependence on the speed of the ship. The antifouling effect is good when the ship is sailing, and the antifouling effect is poor when it is moored. [0003] Chinese patent CN 102731745 A discloses a preparation method and application of a degradable marine antifouling material. It uses a multi-block copolymer formed by the reaction of degraded polyol, isocyanate and a chain extender as the base material, does not cont...
