Abstract

The invention provides a one-component waterborne thermoplastic coating. The coating is applicable to coating ABS (acrylonitrile-butadiene-styrene), PS (polystyrene), HIPS (high impact polystyrene), PC (polycarbonate), PMMA (polymethyl methacrylate) and other types of plastic enclosures; and the coating has the advantages of good adaptability to material surfaces, good substrate adhesive force and good interlayer adhesive force, and solves difficulties such as adhesive force of the waterborne coating on the plastic substrate and a plurality of shrink holes on a UV-radiation curing finish paint matched with the waterborne coating. The coating mainly adopts a waterborne system and is safe for production and application; the coating takes water as a diluent, thus having the advantages of low toxicity, low pollution, extremely low emission of VOCs (volatile organic compounds) and the like and complying with various environmental protection laws and regulations; and meanwhile the coating can be colored with different color paste, thus providing better decorative property for the substrate without affecting the original performance. The invention further provides a production method and a construction method of the product; and the production method and the construction method are simple and convenient, and the adopted production and construction equipment is convenient to wash.

Description

technical field [0001] The application of the present invention relates to a water-based one-component thermoplastic plastic coating, especially a thermoplastic plastic coating matched with UV radiation curing 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 the emission of VOC 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 an...
