Abstract

The invention provides a coating with a long-term stability, belong to the field of coating technology. The coating comprises the following components in percentage by weight: 40-55% of alkyd resin, 4-7% of petroleum resin, 3-25% of pigment, 5-15% of filler, 2-6% of auxiliary agent, 5-15% of organic solvent and 10-15% of surfactant solution with a mass concentration of 2%. The auxiliary agent is a mixture of a dispersing agent, an organobentonite, a catalyst, an anti-skinning agent, a leveling agent and an antifreezing agent at any proportion. The surfactant solution with a mass concentration of 2% is obtained through dissolving the surfactant into water. The product is low in cost, which cannot influence the gloss, adhesion and hardness of the coating. More particularly, the product has a good storing effect, does not have the phenomena such as precipitation, loss of gloss, oil-water separation, pig skin and discoloration after being used for 2 years, and is completely environment-friendly.

Description

technical field [0001] The invention provides a coating with long-term stability, in particular relates to a coating containing a surfactant, and belongs to the technical field of coatings. Background technique [0002] With the rise of crude oil prices, the price of chemical raw materials is increasing day by day. How to reduce the cost of coatings has become a hot topic in the industry. Adding fillers to coatings reduces costs, resulting in the inability to increase gloss; looking for low-cost resin alternatives, resulting in comprehensive Performance cannot be achieved. [0003] One end of the surfactant molecule is a non-extremely lipophilic hydrophobic group, sometimes called a lipophilic group; the other end of the molecule is a polar hydrophilic hydrophilic group, sometimes called an oleophobic group or vividly called a hydrophilic group. water head. Two types of molecular fragments or groups with diametrically opposite structures and properties are located at both ...
