Problems solved by technology

[0009] However, all the above-mentioned materials are faced with a problem: these materials will age, dissolve and precipitate under the influence of light, water scouring and other conditions in the natural environment, resulting in reduced antifouling life; while organic anti-algae materials , the types of anti-algae are narrow, and often need to be compounded; in addition, the above-mentioned materials are still affected by temperature resistance, and it is difficult to meet the anti-fouling and anti-algae processing requirements of plastic and ceramic materials, which limits their use; and the current anti-fouling The field focuses on coatings with broad-spectrum biocidal properties, low toxicity, easy biodegradation, low residue and stability
It can solve the problem of long-term anti-algae and anti-fouling of coatings, paints, plastics, and ceramics, overcome the defects of short anti-algae and anti-fouling life of existing materials, and narrow types of anti-algae, and reduce the amount of anti-algae materials and reduce toxicity to water bodies , in addition to enhancing its economic value, it is of great significance to social and environmental friendly issues

Abstract

The invention discloses an antifouling material, relates to a composite antifouling material, and especially relates to an environment-friendly long-acting composite antifouling material. The environment-friendly long-acting composite antifouling material is characterized by being composed of the following components in percentage by weight: 5 to 70% of silver, 5 to 30% of copper, 20 to 80% of isothiazolinone compounds, and 5 to 50% of metal pyrithione compounds.

Description

technical field [0001] The invention belongs to the field of antifouling and relates to a composite antifouling material, in particular to an environment-friendly and long-acting composite antifouling material. Background technique [0002] For all facilities or supplies in the natural environment, as long as the place is humid and rich in water vapor, there may be algae pollution problems, such as: buildings, exterior walls, bathroom walls, pipelines, bridges, ships, waste water treatment pools, containers, swimming pools , breeding ponds, sewer pipes, etc., are prone to algae growth. Both the attachment and growth of algae can cause damage to these facilities. Therefore, it is very necessary to carry out anti-algae treatment on coatings, paints, plastics, etc. to protect these materials from being damaged by algae. [0003] Especially for the vast marine industry (ocean engineering, fishery, aquaculture, coastal power plants, shipbuilding, shipping), the economic impact ...
