Embodiment 1

[0044] 1. Preparation of polyurea-acrylate emulsion:

[0045] Add 26.1g of hexamethylene diisocyanate into the reaction kettle, raise the temperature to 60°C, add dropwise a mixture of 5.0g of polyether triamine T-5000, 49.9g of polyether diamine D-1000 and 10.0g of acetone, 1.2 After hours of dripping, keep warm for 1.5 hours until the residual -NCO reaches the theoretical value; heat up to 80°C, add 7.0g dimethylolpropionic acid, and react for 2.0 hours; add 12.0g hydroxyethyl acrylate, and react for 0.8 hours to obtain poly For urea prepolymer, cool down to room temperature, and use acetone to control the viscosity during the reaction to avoid rod climbing.

[0046] Stir 72.0g of methyl methacrylate, 23.0g of butyl acrylate, and 0.5g of vinyltrimethoxysilane to obtain a mixed monomer, take 14.3g of the above mixed monomer and put it into the polyurea prepolymer and stir evenly, add 5.3g Stir and neutralize triethylamine for 10 minutes, add 175g of deionized water and emuls...

Embodiment 2

[0054] One, the preparation of described polyurea-acrylate emulsion is as follows:

[0055] Add 19.6g of diphenylmethane diisocyanate into the reaction kettle, raise the temperature to 80°C, add dropwise a mixture of 4.6g of polyether diamine D-230, 70.8g of polyether diamine D-2000 and 15.0g of acetone, for 1.0 hour After dropping, keep warm for 2.0 hours until the residual -NCO reaches the theoretical value; raise the temperature to 90°C, add 3.0 g of sodium ethylenediaminoethanesulfonate, and react for 1.5 hours; add 2.0 g of hydroxybutyl acrylate, and react for 1.0 hour to obtain Polyurea prepolymer, cooled to room temperature, controlled with acetone during the reaction to avoid rod climbing.

[0056] Stir 165g methyl methacrylate, 35g butyl methacrylate, 13g methyl acrylate, 6.5g acrylic acid, and 3.5g vinyl tri-tert-butoxysilane to obtain a mixed monomer, take 21.3g of the above mixed monomer and put it into the polymer Stir in the urea prepolymer for 10 minutes, add 1...

Embodiment 3

[0064] One, the preparation of described polyurea-acrylate emulsion is as follows:

[0065] Add 18.0g of isophorone diisocyanate into the reaction kettle, raise the temperature to 75°C, add dropwise a mixture of 73.4g of polyether diamine D-2000 and 12.0g of acetone, drop it in 0.8 hours, keep it warm for 2.0 hours until the residual - NCO reaches the theoretical value; heat up to 85°C, add 3.0g dimethylol butyric acid and 2.0g 1,4-butanediol-2-sodium sulfonate, react for 2.5 hours; add 3.6g hydroxyethyl methacrylate, react After 1.2 hours, the polyurea prepolymer was prepared, and the temperature was lowered to room temperature. During the reaction, acetone was used to control the reaction to avoid rod climbing.

[0066] Stir 190g of methyl methacrylate, 35g of butyl acrylate, 75g of ethyl acrylate, and 6.0g of vinyltrimethoxysilane to obtain a mixed monomer. Take 18.4g of the above mixed monomer and put it into the polyurea prepolymer and stir evenly. Add 0.8g of sodium hyd...

Abstract

The invention discloses a preparation method of a polyuria-acrylate emulsion and application thereof. The polyuria-acrylate emulsion is prepared by employing a seed emulsion polymerization method and organically combining polyurea and acrylate ester, has the advantages of excellent flexibility and wear resistance of polyurea and good water resistance and high mechanical strength of acrylate ester and overcomes the disadvantages of the two components; and aqueous gravure ink prepared from the emulsion is substantially improved in performances. The prepared aqueous gravure ink is nontoxic, odorless, strong in adhesive force to PP base material, good in flexibility and excellent in heat resistance and water resistance, and is applicable to furniture production, interior decoration and the like, such as printing of surfaces of decorative plates, grainy paper and plastic cement.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a polyurea-acrylate emulsion and a water-based gravure ink prepared therefrom. Background technique [0002] At present, there are two ways to prepare wood grain patterns on the surface of wood grain furniture, floors, etc.: one is to paste solid wood veneer on the surface of the finished furniture, but this will lead to a large number of deforestation and affect nature; the other is to paste simulation Solid wood PVC decorative film, which uses high molecular polymer PVC as raw material, adding various additives, calendering, compounding, and printing wood grain patterns to make a simulated solid wood decorative film. The decorative film has realistic wood grain and good decorative effect, and can reduce the felling of trees. [0003] With the development of social economy and the progress of human civilization, people have higher and higher requirements ...
