Green and environment-friendly antifouling paint for fishing boats, and fouling-panel testing method

Abstract

The invention provides a green and environment-friendly antifouling paint for fishing boats. The antifouling paint is characterized in that in the green and environment-friendly antifouling paint, the content of a volatile organic compound (VOC) is less than or equal to 450 g / L, the mass fraction of benzene, toluene, dimethyl benzene and ethylbenzene is less than or equal to 25%, the total mass fraction of copper is less than or equal to 25%, and other toxic substances that are explicitly forbidden or restricted in the standard of Technical requirement for environmental labeling products Ship anti-fouling paints are not added initiatively; and the green and environment-friendly antifouling paint for the fishing boats adopts modified zinc acrylate resin, rosin, liquid bisphenol A epoxy resin and compound anti-soil agent, does not gel after being stored for a long time, and has excellent anti-cracking and anti-stripping performances. An antifouling paint sample shallow sea immersion testing method is characterized in that plastic boards such as PVC (polyvinyl chloride), coated or uncoated steel, stainless steel, copper, copper alloy, aluminium, aluminium alloy, titanium alloy anti-decaying paint or tie coat of the titanium alloy anti-decaying paint is adopted, and then the testing antifouling paint is applied to perform a shallow sea immersion test.

Description

technical field [0001] The invention relates to the field of antifouling paint, in particular to a green and environment-friendly fishing boat antifouling paint and a shallow sea immersion test method thereof. Background technique [0002] Human beings have been facing the problem of marine biofouling since they exploited and developed the ocean. Marine biofouling will increase the weight of underwater structures and water flow resistance, resulting in serious economic losses, and even damage structures, leading to safety accidents. For safety and benefit, the common practice is to apply marine antifouling paint. [0003] With the continuous promulgation and improvement of laws and regulations to protect the ecological environment in various countries, the development of marine antifouling coatings is no longer just focusing on antifouling performance like traditional coatings. The development of green and environmentally friendly coatings has become an inevitable trend in ...

Problems solved by technology

2-Mercaptopyridine compound can prevent the adhesion of crustaceans, algae, etc., and it will provide better antifouling effect when used together with copper-based antifouling agents such as cuprous oxide. However, antifouling paints containing zinc acrylate polymers, if simultaneously Contains copper-based antifouling agents such as cuprous oxide, rosin and 2-mercaptopyridine oxide compounds, which will reduce storage stability. Antifouling paints will randomly thicken, thicken, or even gel due to different conditions. Typical examples There is no antifouling paint containing rosin, cuprous oxide and zinc pyrithione on the market

[0010] "GB 5370-2007 Antifouling Paint Sample Shallow Sea Immersion Test Method" is inconvenient to directly compare the effects of different antifouling paint systems

At the same time, antifouling paint researchers found that due to the complexity of the seawater environment, samples of the same formula in different locations often show different antifouling effects. Therefore, starting from their own research needs, hanging wooden frames, hanging polyvinyl chloride (PVC) and other plastic plates are subjected to multi-formulation shallow sea immersion tests to make them more comparable, but only for specific supporting systems
