Abstract

The invention provides waterborne single-component thermoplastic plastic paint and a production method and construction method thereof. The plastic paint is suitable for the coating of plastic cabinet prepared from ABS (Acrylonitrile Butadiene Styrene), PS (poly styrene), HIPS (High Impact Polystyrene), PC (polycarbonate), PMMA (polymethyl methacrylate) and the like, has good adaptability to the surface of the material and also has good adhesive force, thus the adhesive force problem of the waterborne paint on the plastic substrate can be solved. A waterborne system is adopted for the paint mainly adopts, the production and using processes are safe; and water is used as diluent, and the paint has the advantages of low toxicity, low pollution, extremely low volatile organic compound (VOC) emission and the like and meets various laws and regulations on environmental protection. Meanwhile, the paint can use different color pastes for coloring; and the paint has better decorative propertyon the substrate while the properties can not be affected. Compared with the common solvent thermoplastic acrylic paint, the paint only uses a small amount of low-toxicity alcohol ether type organic solvent, thus the influence on the plastic substrate is extremely small; and the paint film has bright colour, full appearance effect and good performances.

Description

technical field [0001] The application of the present invention relates to a water-based one-component thermoplastic plastic coating and its production and construction methods, belonging to the technical field of chemical coatings. technical background [0002] The perfect decorative and durable protective properties of coatings make the coatings industry develop rapidly. With the continuous strengthening of environmental protection awareness and the increasing improvement of environmental protection regulations, people's requirements for environmental protection and awareness of coating pollution are getting higher and higher. , various countries have strictly controlled VOC emissions and restricted the production and use of high-VOC coating products to the height of laws and regulations. [0003] In the wave of environmental protection, water-based coatings are an important trend and approach, but due to the high surface tension of water and plastics, the interface is dif...
