Problems solved by technology

At present, most of the anti-rust paints and anti-corrosion coatings used in China are solvent-based coatings. The biggest disadvantage of these coatings is that they pollute the environment, are flammable and explosive, harmful to the human body, and waste a lot of resources and energy.
At present, the VOC content of solvent-based coating products in the market is as high as 50% to 60%, and the annual emission of VOC is nearly 200,000 tons, which not only pollutes the environment but also wastes energy. Therefore, the development of water-based anti-corrosion coatings will be a priority for the domestic and foreign coatings industry focus
Water-based anti-corrosion coatings widely used in the market now include water-based inorganic zinc-rich, water-based epoxy coatings, etc. These coatings are used in primers, which require high substrate treatment and cumbersome construction.
Water-based acrylic anti-corrosion coatings are produced by some foreign manufacturers, but they are not effective in anti-corrosion, salt spray resistance and adhesion. In addition, anti-corrosion pigments such as iron oxide red and composite iron-titanium powder are mainly used in water-based acrylic anti-corrosion coatings, which are not suitable for adjustment. color, the effect is not good when used as a topcoat

Embodiment 1

[0031] Add 18.42g of water into the batching tank according to the raw material names and proportions listed in Table 2, and add 0.59g of dispersant, 0.2g of defoamer, 0.2g of wetting agent, 0.09g of antifungal agent, and salt spray resistance under stirring. 2.5g of anti-flash rust agent, 1.0g of anti-flash rust agent, after stirring evenly, add an appropriate amount of pH regulator to adjust the pH value of the system, and make the pH value reach the range of 8.0-9.0, then add pigments, fillers and anti-corrosion pigments, stir well and put The material is pumped into a sand mill for grinding. When the fineness of the slurry is less than or equal to 50 μm, add 719F emulsion, add 3g of film-forming aid under stirring, and add thickener RM20201g, TT-9351g according to the viscosity requirements of the paint. When the product reaches the standard Finally, filter and pack with 80-100 mesh screen to obtain the finished product.

Embodiment 2-7

[0033] Adopt the same method as embodiment 1 to prepare water-based modified pure acrylic acid anticorrosion paint, the used raw material name and proportioning ratio of embodiment 2-7 are as shown in table 2.

Abstract

The invention relates to a water-based modified pure acrylic acid anticorrosive paint which is prepared from the following components in percentage by mass: 30-45% of modified acrylic acid emulsion, 3-5% of film-forming assistant, 0.6-1.2% of dispersant, 0.1-1.0% of defoaming agent, 0.1-0.2% of wetting agent, 0.05-0.10% of mold preventive, 1-2% of flash-rust inhibitor, 2-5% of pigment, 15-30% of antirust pigment and filler, 2-5% of filler, 2-5% of thickening agent, 1-2.5% of salt-fog inhibitor and the balance of water. The PH value is regulated to 8-9. The anticorrosive paint provided by the invention has the advantages of combined primer and precoat functions, single component and self drying, is water-based, and satisfies the requirement for environmental protection. The invention has the advantages of simple production technique, accessible raw materials, low cost, low VOC (volatile organic compound), environmental protection and high safety, can easily implement industrialization, and is simple and convenient for construction.

Description

technical field [0001] The invention relates to a water-based modified pure acrylic paint. technical background [0002] The 21st century is a century of environmental protection. Resource-saving, energy-saving, and pollution-free are the main development directions of the world's coatings. Most of the anti-rust paints and anti-corrosion coatings used in China are solvent-based coatings. The biggest disadvantage of these coatings is that they pollute the environment, are flammable and explosive, are harmful to the human body, and waste a lot of resources and energy. At present, the VOC content of solvent-based coating products in the market is as high as 50% to 60%, and the annual emission of VOC is nearly 200,000 tons, which not only pollutes the environment but also wastes energy. where the focus is. Water-based anti-corrosion coatings widely used in the market now include water-based inorganic zinc-rich coatings, water-based epoxy coatings, etc. These coatings are used...
