Water-based cold sprayed steel drum paint with oil stain resistance

Abstract

The invention discloses water-based cold sprayed steel drum paint with oil stain resistance. The paint is prepared from components in parts by weight as follows: 30-35 parts of waterborne acrylic resin, 8-10 parts of amino resin, 1-3 parts of an adhesion promoter, 20-25 parts of a cosolvent, 2-3 parts of a dispersant, 0.05-0.1 parts of a compound additive, 30-35 parts of pigment concentrate and 4-7 parts of water, wherein the cosolvent is a mixed solution prepared from 2-(2-butoxyethoxy)ethyl acetate and ethanol in a weight ratio being 1:1; the compound additive is prepared from butyldiglycoland polyether siloxane in a weight ratio being 1:(1-3). Phenomena such as cratering, sagging, floating and the like of a paint film due to unclean substrate of the conventional water-based or solventtype steel drum paint can be prevented, the requirement for cleaning treatment of a steel drum is low, the steel drum is not needed to be preheated during painting, so that the steel drum painting construction process is simplified remarkably, construction conditions are reduced, working efficiency is increased, energy is saved, cost is reduced, and higher profit ratio is realized for a customer.

Description

technical field [0001] The invention relates to the paint industry, in particular to a water-based baking paint specially used for steel drums, in particular to a water-based oil stain-resistant cold-spray paint for steel drums. Background technique [0002] Today, with higher and higher requirements for energy saving and environmental protection, most steel drums use solvent-based steel drum paints that are baked at high temperature or water-based baking steel drum paints. These steel drum paints need to be pre-painted in the early stage of spraying The various properties of steel drum paint can only be achieved after high-temperature baking. Due to the limitation of construction technology, the production capacity of the enterprise is greatly reduced, which increases the cost of the enterprise. And during the construction process, because the substrates of most companies are not treated very cleanly and have a small amount of oil stains, especially water-based steel drum p...

Problems solved by technology

And during the construction process, because most of the company's substrates are not treated cleanly and have a small amount of oil stains, especially water-based steel drum paints, shrinkage cavities are prone to appear on the substrate paint surface during the construction process, the color of the paint film is dark, and the adhesion is poor. Uneven spraying, easy to sag, and easy to appear bubbles, shrinkage cavities, orange peel and other defects during high-temperature baking, which greatly reduces the performance of the paint film
