Water-based plastic paint, and preparation method and application thereof

Abstract

The invention discloses a water-based plastic paint, and a preparation method and application thereof, and belongs to the technical field of chemical industry. The water-based plastic paint comprises the following raw materials in parts by weight: 45-50 parts of water-based acrylic emulsion, 1-2 parts of water-based wetting agent, 0.5-1 part of defoaming agent and 45-50 parts of deionized water. The preparation method of the water-based plastic paint comprises the following steps: (1) performing dilution with the deionized water; and (2) forming a film through low-temperature baking. The water-based plastic paint is used for painting and protection of ABS and PC plastic surfaces. According to the invention, the deionized water is used as a diluent, thereby ensuring the quality of the paint film; since the water-based wetting agent has the characteristic of reducing surface tension, the water-based wetting agent is added into the deionized water to avoid producing the phenomena of oil whirling, pinholing and the like due to high surface tension of the water; compared with the traditional paint, the water-based plastic paint disclosed by the invention realizes zero carcinogen discharge, thereby ensuring the physical health of a painter and a user; and no VOC is discharged to the atmosphere, thereby reducing the pollution to the atmosphere.

Description

Technical field [0001] The invention belongs to the technical field of chemical coatings, and particularly relates to a water-based plastic paint and a preparation method and application thereof. Background technique [0002] Traditional paint has been deeply rooted among consumers, and many consumers still know very little about traditional paint. Traditional paint can only be free of pungent odor one month after spraying. There is no pungent odor, but the formaldehyde volatilizes to the level acceptable to human physiology. The benzene and toluene contained in traditional paint curing agent and thinner are free TDI will continue to evaporate, and it will take at least several decades for harmful substances to evaporate completely. These aromatic hydrocarbons have a great impact on the intellectual development of infants, children and unborn children. Free TDI also has the risk of causing cancer. The use of traditional paint has long been banned in developed European countries....

Problems solved by technology

However, the solvent used in this patent is ordinary water with a lot of metal ions. The metal ions in it accumulate together, resulting in poor dispersion of other raw materials added, and easy stickiness or lumps, making it difficult to form a complete paint during construction. In addition, during the construction process, air bubbles will also be produced, which will affect the decorative effect and durability
