Abstract

The invention discloses water-based plastic paint applicable to a composite layer coating film. The water-based plastic paint consists of the following components in parts by weight: 45 to 60 parts of water-based acrylic acid emulsion, 10 to 25 parts of deionized water, 1 to 2 parts of aid, 2 to 4 parts of LTW resin, 1 to 2 parts of 25% ammonia water, 5 to 17 parts of cosolvent, 1 to 5 parts of alkali swelling thickening agent and 5 to 30 parts of pigment. The invention discloses a preparation process of the water-based plastic paint. The water-based plastic paint can perform implementation of a composite layer paint film and also can perform implementation in combination with solvent type plastic paint, and the formed coating has ideal physical properties.

Description

technical field [0001] The invention relates to a water-based plastic paint, in particular to a water-based plastic paint suitable for composite layer coating, and also relates to a preparation process of the water-based plastic paint. Background technique [0002] Coating of household appliances is an important part of the manufacturing process of household appliances. It can enhance the durability of plastic materials and provide decorative effects, so it has attracted the attention and attention of the industry. Water-based plastic paint has a better performance in preventing plastic from being corroded and protecting the environment. At present, the construction of composite layer paint film and the construction of solvent-based plastic paint are mostly used, but the adhesion of the composite layer layer and the water resistance of the composite layer paint film need to be improved. Contents of the invention [0003] One of the objectives of the present invention is t...
