Problems solved by technology

[0004] The existing paint will form a coating film on the surface of the product after being coated. After the coating film is irradiated by sunlight, because the sunlight contains ultraviolet rays, it will cause cracks in the coating film after a long time, and sometimes in the process of forming the coating film In, peeling is easy to occur

preparation example Construction

[0027] A kind of preparation method of the flame-retardant type acrylic resin coating of sustained release negative oxygen ion, comprises the following steps:

[0028] S1, take the raw material according to the amount, set aside;

[0029] S2. Put water, acrylic resin, nano-hexacyclite particles, alkylphenol polyoxyethylene ether, sodium dodecylbenzenesulfonate, polydimethylsiloxane and xylylenediamine into the reaction kettle and heat up to 65°C, then began to stir and mix at a speed of 800r / min;

[0030] S3. Continue to add nitrogen and phosphorus series flame retardants, talc powder, flame retardant synergists and thickeners into the reactor and stir at a speed of 900r / min until they are completely dissolved and dispersed evenly. The temperature during the stirring process is controlled at 65°C-75°C ℃;

[0031] S4. Keep the temperature at 65°C-75°C, add copolymer compound, methacryloxypropyltrimethyloxysilane and wetting agent, raise the temperature of the reaction kettle ...

Abstract

The invention relates to the technical field of preparation of resin coating, in particular to flame-retardant acrylic resin coating capable of slowly releasing negative oxygen ions and a preparation method thereof. The coating is prepared from the following raw materials in parts by mass: 90 to 100 parts of water, 75 to 85 parts of acrylic resin, 35 to 45 parts of nano Liuhuan stone particles, 6 to 12 parts of alkylphenol polyoxyethylene ether, 2 to 6 parts of sodium dodecyl benzene sulfonate, 6 to 12 parts of a nitrogen-phosphorus series flame retardant, 2 to 6 parts of a flame-retardant synergist, 3 to 5 parts of a wetting agent and 3 to 5 parts of polydimethylsiloxane. The preparation method comprises the following steps: S1, weighing the raw materials according to the weight for later use; S2, adding the water, the acrylic resin, the nano Liuhuan stone particles, the alkylphenol polyoxyethylene ether, the sodium dodecyl benzene sulfonate, the polydimethylsiloxane and xylylenediamine into a reaction kettle, heating, and uniformly stirring and mixing. According to the invention, the phenomenon that cracks are generated due to the influence of ultraviolet rays after the coating is coated can be relieved, the peeling phenomenon of a coating film formed by the coating can be relieved.

Description

technical field [0001] The invention relates to the technical field of preparation of resin coatings, in particular to a flame-retardant acrylic resin coating which slowly releases negative oxygen ions and a preparation method thereof. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] Through the organic combination of polymer materials and negative oxygen ion materials, using the principle of air energy activation and the potential difference of porous materials deposited on the surface, the light negative charge is released for a long time, and the light negative charge combines with oxygen molecules in the air to form a highly active air vitamin...
