Preparation and application of a copper-zinc acrylate composite self-polishing antifouling resin

Abstract

The invention discloses copper and zinc acrylate compound self-polishing anti-pollution resin, the number-average molecular weight of which is 10000-25000 and the molecular weight distribution of which is 1.1-2.5. The resin has a synergistic effect and is free of cracks and hard to peel off, and the matrix resin as an anti-pollution coating has a good self-polishing performance and storage stability. The anti-pollution coating prepared from the resin has the advantages of being long in anti-pollution period, excellent in anti-pollution performance, excellent drag reduction performance, marine environmental-friendly, easy to construct and the like and can satisfy the requirement of underwater facilities on the anti-pollution coating. The invention further discloses a method for preparing the resin and a coating comprising the resin.

Description

technical field

[0001] The invention relates to the field of antifouling coatings. More specifically, it relates to a copper-zinc acrylate composite self-polishing antifouling resin and its preparation and application. Background technique

[0002] Marine biofouling will increase the weight of the hull, increase navigation resistance, reduce speed, increase fuel consumption, and even cause surface corrosion, which will significantly increase the maintenance workload and bring huge economic losses. Since ancient times, humans have taken various measures to prevent marine organisms from adhering. After continuous attempts, the application of marine antifouling coatings has become the most effective, convenient, economical and feasible method to solve marine biofouling.

[0003] Self-polishing technology emerged in the mid-1970s. In the past few decades, antifouling coatings containing organotins have been widely used, but the released organotin poisons have caused teratogeni...
