Problems solved by technology

[0005] 1. There are many types of plastic toy substrates, covering ABS, PS, HIPS, PET, PVC and other substrates. Solvent-based technology is relatively mature, while the adhesion of water-based coatings needs to be improved, and more research is needed;
[0006] 2. Plastic toys require that the limit of harmful substances such as heavy metals must meet the specific requirements of the country or the importing countries such as the European Union and the United States. Therefore, water-based coatings have certain limitations in terms of improving performance and increasing antibacterial functions;
[0007] 3. There is still a certain gap between the overall physical and chemical performance indicators of water-based coatings and solvent-based coatings

Embodiment 1

[0028] An antibacterial plastic toy water paint is composed of A component and B component.

[0029] Among them, component A is prepared by mixing water-based resin and auxiliary agents, and in parts by weight, it includes: 75 parts of polyurethane resin, 5 parts of environmental protection solvent, 2 parts of neutralizer, 0.2 part of defoamer, 0.2 part of 0.2 parts of wetting agent, 3 parts of antibacterial agent solution, 14.2 parts of deionized water, 0.2 parts of thickener.

[0030] The polyurethane resin in component A is obtained by mixing water-based low-hydroxyl value polyurethane and water-based high-hydroxyl value polyurethane in a weight ratio of 2:1.

[0031] The antibacterial agent solution in the component A is obtained by diluting the silver ion antibacterial agent with water. In parts by weight, 90 parts of deionized water are added to every 10 parts of the silver ion antibacterial agent.

[0032] Component B is prepared by mixing a curing agent and a cosolven...

Abstract

The invention relates to the technical field of paint, in particular to the technical field of water-based paint, and in particular discloses an antibacterial water-based paint for plastic toys. The antibacterial water-based paint for the plastic toys is prepared by mixing two types of waterborne polyurethane having different hydroxyl values and two types of isocyanate having different NCO contents, and adding an antibacterial agent; the physical and chemical properties of the obtained water-based paint reach the standard of solvent type products; the water-based paint is good in adhesion force, after-tack resistance and water resistance, low in contents of poisonous and harmful substances such as heavy metals, safe and environmentally-friendly, and good in application property.

Description

technical field [0001] The present invention relates to the technical field of coatings, in particular to the technical field of water-based coatings. Background technique [0002] my country is a big exporter of toys, and plastic toys occupy a large share of the market. At present, it is still dominated by solvent-based coatings, and water-based plastic toy coatings account for a small share. Water-based toy coatings with functions such as antibacterial and high wear resistance are more It is rare. [0003] Due to the high content of volatile organic compounds (volatile organic compounds, referred to as VOC) in solvent-based coatings, there are air pollution, flammability, potential safety hazards, poor environmental protection and other problems in use. In the future, water-based plastic toy coatings will be used instead of solvent-based coatings. Paint is an inevitable trend. [0004] However, the further application of water-based plastic toy coatings still has the foll...
