Problems solved by technology

[0004] In view of the technical problems that the existing water-based steel drum paint is prone to defects and the performance of the paint film is obviously reduced when it is applied on the surface of the unclean steel drum, the present invention provides a water-based steel drum paint and a preparation method thereof. The water-based paint film of the steel drum paint is The wetting effect of the oily surface is good, even if the bottom of the steel drum is not thoroughly treated and there is a small amount of oil, the spreading state of the paint film is still good

Abstract

The invention relates to the technical field of water-based paint, in particular to water-based steel drum paint and a preparation method thereof. The steel drum paint comprises the following raw materials in parts by weight: 25-40 parts of water-based alkyd resin, 4-10 parts of water-based tert-fluoroacrylic emulsion, 4-10 parts of water-based amino resin, 12-25 parts of cosolvent, 0-10 parts ofpigment, 1-3 parts of adhesion promoter, 0.5-2 parts of dispersing agent, 0.2-1 part of thickening agent and 10-30 parts of distilled water. The preparation method comprises the following steps: weighing raw materials, preparing a mixed solution A, preparing a mixed solution B and mixing the solutions. The water-based steel drum paint disclosed by the invention can be sprayed on the surface of anunclean steel drum with a small amount of impurities such as greasy dirt and the like, a good spraying effect is achieved, the glossiness, the strength and the adhesive force are high, the water-basedsteel drum paint has excellent water resistance and weather resistance, and a paint film does not have the defects of shrinkage cavities, orange peel, sagging and the like after being sprayed; the water-based steel drum paint provided by the invention is simple in preparation process, can be produced in batches, and saves time and resources.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based steel drum paint and a preparation method thereof. Background technique [0002] With the continuous development of industry, water-based steel drum paint has been widely used in product packaging in various industries. Generally, during the construction of water-based steel drum paint, it needs to be preheated in the early stage of spraying, and then baked at high temperature to achieve the required various properties. Due to the limitation of the construction technology, the production cost of the enterprise is relatively high, and the production capacity is obviously reduced; To meet cleanliness standards, oil stains often remain on the surface of steel drums, which directly lead to defects such as paint shrinkage cavities, air bubbles, orange peel, dark paint film color, poor adhesion, uneven spraying and easy sagging during the construction process, ...
