Abstract

The invention puts forward an aqueous single-ingredient inorganic high-temperature antiseptic paint and a preparation method thereof. The paint is prepared from the following raw materials in parts byweight: 30-70% of inorganic silicone and 30-70% of filler. The preparation method for the aqueous single-ingredient inorganic high-temperature antiseptic paint comprises the following steps: S1: burdening: according to the ratio of the aqueous single-ingredient inorganic high-temperature antiseptic paint, weighing inorganic silicone and filler, mixing, stirring, and evenly dispersing; S2: carrying out superfine grinding: grinding mixture which is evenly dispersed, and controlling the average grain size D50 of the mixture to be between 1.5 and 1.7mu m to prepare the aqueous single-ingredient inorganic high-temperature antiseptic paint. The paint has the advantages of excellent high temperature resistance and quenching and quick heat resistance, high intensity, good toughness, salt mist resistance and chemical corrosion resistance. The aqueous single-ingredient inorganic high-temperature antiseptic paint can be used at a high temperature of 700-1000 DEG C, is clean and environmentally friendly, is free from VOC (Volatile Organic Compound) emission, is a breakthrough for the inorganic antiseptic paint and is convenient in construction, and the construction quality of the paint can beguaranteed.

Description

technical field [0001] The invention relates to a water-based one-component inorganic high-temperature anticorrosion paint and a preparation method thereof, belonging to the field of industrial paint preparation. The inorganic coating is used for anticorrosion of industrial equipment and devices, has good anticorrosion performance, is simple and convenient in coating construction, and can be used in a high temperature environment of 700-1000°C. It is an industrial anti-corrosion coating with wide adaptability. Background technique [0002] The vast majority of anti-corrosion coatings currently on the market are organic anti-corrosion coatings based on organic resin emulsions, plus fillers and anti-corrosion pigments. The high temperature resistance of this kind of coating is poor, and when it is used at a high temperature above 700 ° C, the organic base material in the coating will be oxidized at high temperature and pulverized, thereby causing the coating to fail. Among t...
