Problems solved by technology

At present, most antifouling coatings use cuprous oxide, copper pyrithione, etc. as antifouling agents, which not only do not meet the requirements of environmental protection, but also use organic solvents in traditional antifouling coatings, which will release volatile organic gases (VOC), which will aggravate the pollute the environment and harm the health of workers

Abstract

The invention discloses a water-based composite anti-fouling light coating. The raw materials include: styrene-acrylic emulsion 20-40, acrylate emulsion 15-25, silica sol 5-12, light microsphere additive 15-30, inorganic Pigment and filler 2‑10, wetting agent 1‑2, thickener 1‑4, defoamer 0.1‑2, film-forming aid 1‑2, antifungal agent 1‑2, antifreeze agent 1‑2, pH adjustment Agent 1‑5, water 40‑80. The invention discloses the above-mentioned water-based composite anti-fouling light coating, which comprises: stirring styrene-acrylic emulsion, acrylate emulsion, silica sol, and film-forming aids at a low speed to obtain material a; stirring water, adding inorganic pigments and fillers sequentially under the stirring state , wetting agent, thickener, defoamer, antifungal agent, antifreeze, and stir at a high speed to obtain material b; add light microsphere additives and material a to material b in turn and stir, then add pH regulator and stir A water-based composite anti-fouling lightweight coating is obtained uniformly.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to a water-based composite antifouling lightweight coating and a preparation method thereof. Background technique [0002] Water is an extremely abundant resource on the earth, and it is easy to use and low in cost. Water-based coatings use water as a dispersion medium and thinner. Compared with organic solvent-based coatings, water-based coatings greatly reduce the pollution of the atmosphere caused by the volatilization of organic solvents in the coating and the fire hazard during construction. With the enhancement of people's awareness of environmental protection, the use of water-based coatings is increasing year by year, which will gradually become the mainstream direction of the development of the modern coatings industry. China's coatings industry has shown a trend of rapid growth in recent years. In addition to the substantial growth of architectural coatings, ...
