Water-based environment-friendly steel drum paint and preparation method thereof

Abstract

The invention relates to the technical field of water-based paints, and concretely relates to water-based environment-friendly steel drum paint and a preparation method thereof. The steel drum paint comprises, by weight, 20-40 parts of water-based polyester resin, 10-30 parts of deionized water, 0.5-2 parts of a water-based defoamer, 1-3 parts of a neutralizer, 10-20 parts of a pigment filler, 3-5parts of a cosolvent, 5-10 parts of amino resin, 0.5-3 parts of a water-based surface aid, 0.3-0.6 part of a water-based leveling agent, 1-3 parts of an adhesion promoter and 0.3-1.5 parts of an anti-settling agent. The preparation method comprises the following steps: sequentially adding the water-based polyester resin, the water-based defoamer, the neutralizer, the deionized water and the pigment filler into a cylinder, stirring, transferring into a sand mill, and grinding; slowly adding the water-based surface aid, the water-based leveling agent, the adhesion promoter, the amino resin, thecosolvent and the anti-settling agent, filtering and packaging. The steel drum paint is good in constructability, low in VOC, simple in preparation method and capable of well meeting market requirements.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based environment-friendly steel drum paint and a preparation method thereof. Background technique [0002] Most of the existing steel drum paints are oil-based paints, which are very harmful to human health and the environment during use. Water-based coatings can greatly reduce VOC emissions and ensure the health of operators. [0003] However, the water-based steel drum paint currently on the market has technical problems such as poor workability and high VOC emissions; at the same time, because the steel drum paint is a high-temperature baking paint, it needs to be baked at a temperature above 160°C for 10-20 minutes. Since metallic paint is a self-drying paint, its hardness and acid and alkali resistance cannot meet the requirements of steel drum paint, so it cannot be used instead of steel drum paint. [0004] Based on this, it is imminent to provide a wa...
