Abstract

The invention discloses a low-temperature-resistant water-based automobile coating prepared from the following components in parts by weight: 60 parts of a water-based acrylic emulsion, 3 parts of a coalescing agent, 0.5 part of a defoamer, 0.3 part of a wetting leveling agent, 2 parts of a rheological auxiliary agent, 1.5 parts of a surface control additive, 0.1 part of a delustering agent, 0.05part of a preservative, 0.05 part of a pH regulator, 10 parts of a pigment and the balance being water. The invention further discloses a preparation method of the water-based automobile coating. Themethod comprises the following steps: S1, adding the water-based acrylic emulsion, the pigment and water, and stirring; S2, adding the defoamer, a wetting leveling agent, the rheological auxiliary agent, the surface control additive, the delustering agent, the preservative, the pH regulator and the coalescing agent into the mixture obtained in the S1, and stirring; and S3, preparing the low-temperature-resistant water-based automobile coating. According to a preparation device disclosed by the invention, the preparation condition of the coating can be observed in real time, the preparation information can be obtained, the coating provided by the invention has a low-temperature anti-freezing property, and the phenomena of whitening and cracking of the coating are avoided.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a low-temperature-resistant water-based automotive coating, a preparation method and equipment. Background technique [0002] As one of the most important means of transportation in today's society, automobiles are highly valued by the public for their appearance while ensuring their performance. By painting the surface of automobiles, the body will not be easily corroded. Automobile coatings have the following advantages Functions: (1) beautify the appearance of the car; (2) excellent construction and matching, automotive paints are generally multi-layer coatings, because single-layer coatings generally cannot achieve good performance, so each coating is required (3) Excellent mechanical properties, suitable for high speed, multiple shocks and strains of automobiles, requiring good adhesion of the paint film, hard and flexible, impact resistance, bending resistance,...
