Problems solved by technology

[0003] In this regard, the market provides temperature-sensitive materials mixed with antifouling agents to prepare antifouling coatings. Controlled release of antifouling agents can be selected through temperature control. Although it provides a new direction, there are high costs and problems in the actual application process. The defects of poor comprehensive performance, and the general toxicity of antifouling agents, long-term use can easily cause great harm to the ocean, so it is necessary to find a new direction

Embodiment 1

[0025] The formula is as follows: epoxy resin 33, ethylene glycol 9, methyl salicylic acid 14, sodium polyacrylate 0.4, stannous pyrophosphate 0.2, rust inhibitor 0.22, sodium lauryl sulfate 1.5, polyvinyl alcohol 1.5, aluminum silicate 7. Tricresyl phosphate 4, zinc powder 9, mica iron oxide 9, modified sepiolite 4, barium metaborate 9, silica sol 4, zinc naphthenate 3, polysiloxane defoamer 0.2, of which anti Rust agent formula: citric acid 50, aluminum powder 0.8, animal glue 0.4, tricresyl phosphate 0.3, talcum powder 1;

[0026] First add water to the total amount of 100, add the above formula in proportion to mix and stir, grind to a particle size of 25-40 μm, stir for 25 minutes, and filter with a 280-mesh filter cloth.

[0027] 2. Preparation of film layer

[0028] 1. Preparation of temperature-sensitive copolymer: by weight, put 5-10 parts of tetrahydrofuran solvent into a container and heat it to 70-90°C; then take 30-50 parts of solvent and mix 15-25 parts of N-iso...

Embodiment 2

[0032] The film layer is prepared as follows: a. Preparation of temperature-sensitive copolymer: in parts by weight, put 5 parts of tetrahydrofuran solvent into a container and heat to 80°C; then take 40 parts of solvent and mix 20 parts of N-isopropylacrylamide , 2 parts of methyl methacrylate, 2 parts of methyl acrylate mixed solvent, stir and add 0.026 parts of initiator, choose azobisisobutyronitrile, and then add tetrahydrofuran to react in the container, add it in a dripping manner, and continue for 1.5h , keeping the reaction temperature at 80°C, after 4 hours, cooling and discharging to prepare a temperature-sensitive copolymer;

[0033] b. Preparation of ion exchange resin: the organic acid is a monobasic acid, acetic acid is selected as the initiator, and azobisisobutyronitrile is selected as the initiator; first, 45 parts of xylene solvent is added to the container, and heated to 80 °C; then 8 parts of acrylic acid, 45 parts of methyl butyl acrylate, add 0.5 parts o...

Embodiment 3

[0043] The formula is as follows, by mass: film-forming substance: 40% of acrylic resin, 1% of natural rubber, 3% of paraffin, 3% of stearic acid; solvent: 18% of isopropanol; coating additive: defoamer (tributyl phosphate Ester) 4%, emulsifier (silicone oil) 1%, UV absorber 1%, antistatic agent 0.6%, coupling agent (titanate) 0.6%, humectant (glycerin) 1.4%, leveling agent (acrylic acid) 0.8%; filler: titanium dioxide 12%, light calcium 8%, organosilicon hollow microbeads 5%, water-based color paste 0.5%.

[0044] Method: first heat the oil-water amphoteric acrylic resin to 55°C in a glass-lined pot to make the resin thinner; then heat the paraffin and stearic acid to 85°C in a glass-lined pot to dissolve them all; then heat the heated Slowly add natural rubber to acrylic resin under stirring, then slowly add dissolved paraffin wax and stearic acid in sequence, then add tributyl phosphate and silicone oil, and stir for half an hour; then add 70% isopropanol, Control the temp...

Abstract

The present invention provides a preparation method of a reversible dynamic hole paint layer, a three-layer structure is adopted, a film layer and a base material are fixed through primer liquid, the temperature is reduced so that pore channels of the dynamic hole film layer can be closed, then low-surface paint coating is sprayed to form a low-surface layer, the surface area of the film layer is changed under the temperature change, and the low-surface layer is driven to deform, and the anti-fouling performance is good, the comprehensive performance is good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of paint materials, in particular to a preparation method of a reversible dynamic hole paint layer. Background technique [0002] In the process of developing the ocean, marine biofouling brings great harm to ships, such as increasing navigation resistance, weight, and accelerated corrosion. The main principle of coating antifouling is hydrolysis and controlled release of antifouling agent for the damage of marine organisms to ships. There is a risk of failure due to insufficient release of antifouling agent. [0003] In this regard, the market provides temperature-sensitive materials mixed with antifouling agents to prepare antifouling coatings, and selects controlled release antifouling agents through temperature control. Although it provides a new direction, there are high costs, high costs, and The defects of poor comprehensive performance, and the general toxicity of antifouling agents, long-term use w...
