Water-based metal anti-corrosion heat-insulation coating for petroleum equipment and preparation method thereof

Abstract

The invention relates to a water-based metal anti-corrosion heat-insulation coating for petroleum equipment and a preparation method thereof. The water-based metal anti-corrosion heat-insulation coating comprises the following components in parts by mass: A, slurry components: resin, a cosolvent, a first part of a pH value regulator, a drier, a dispersing agent, a first part of a defoaming agent,an anti-settling agent, a decorative pigment, a near-infrared reflective heat-insulation material and an anti-rust pigment; and B, paint blend components: slurry, acrylic emulsion, inorganic compositegel, a coalescing agent, a second part of a PH value regulator, a second part of a defoaming agent, a base material wetting agent, an anti-flash-rust agent, a salt spray resistant aid, a bactericideand a polyurethane leveling modifier. The preparation method of the water-based metal anticorrosive heat-insulating coating comprises the following steps: weighing the raw materials of the coating inparts by mass; sequentially adding the components into a dispersion kettle according to the formula ratio; weighing the raw materials of the coating in parts by mass; and sequentially adding the components into a paint mixing kettle according to the formula ratio. The paint has the advantages of novel and scientific formula, excellent weather resistance, no fading, good stain resistance, no cracking, high hardness, strong adhesion and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a water-based metal anti-corrosion and heat-insulating coating for petroleum equipment and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and social production, energy and the environment have become two major issues of increasing concern to the whole society, and higher requirements have been put forward for energy conservation and environmental protection. In recent years, more and more metal materials have been used in production plants and temporary architectural buildings, especially for some petrochemical storage tanks, pipelines and open-air reactors. High temperature will also bring hidden dangers of production accidents and excessive energy waste. Therefore, it is necessary to use air conditioning or water spraying to cool down in the hot summer. A lot of energy is consumed. Based on this, wat...
