Problems solved by technology

Traditional anti-corrosion and heat-conducting coatings for heat exchangers include epoxy-phenolic anti-corrosion and heat-conducting coatings. This type of coating has excellent acid and alkali resistance, but this type of coating is not heat-resistant, and it is not suitable for use when the working temperature exceeds 200 ° C.

Abstract

The invention discloses an anti-corrosion heat-conducting coating for a heat exchanger and a preparation method of the coating. The formula of the anti-corrosion heating conducting coating comprises the following raw materials by weight percent: 30%-40% of matrix resin, 40%-50% of filler, 0.5%-1% of auxiliaries and 15%-25% of diluting agent, wherein the matrix resin is a mixture of resin A and resin B, the resin A is a SH-023-7 type organic silicon modified epoxy resin product, the resin B is a 2130 type phenolic resin product, and the filler is a mixture of 40%-55% of aluminum nitride, 10%-15% of glass powder, 15%-25% of barium sulfate and 10%-15% of titanium dioxide. With the coating provided by the invention, better anti-corrosion performance and heat-conducting performance of the heat exchanger are realized; and in the filler range, the heat conductivity of the coating is maximally up to 3.912W / (m.k).

Description

technical field [0001] The invention relates to an anti-corrosion and heat-conducting coating, in particular to an anti-corrosion and heat-conducting coating for a heat exchanger and a preparation method thereof. Background technique [0002] As an indispensable equipment in the chemical industry, heat exchangers cost about 10%-40% of the total investment, and the corrosion of heat exchangers causes huge economic losses every year. Anti-corrosion and heat-conducting coatings for heat exchangers not only need to ensure sufficient corrosion resistance, but also ensure good thermal conductivity. Traditional anti-corrosion and heat-conducting coatings for heat exchangers include epoxy-phenolic anti-corrosion and heat-conducting coatings. This type of coating has excellent acid and alkali resistance, but this type of coating is not heat-resistant, and it is not suitable for use when the working temperature exceeds 200 ° C. . Contents of the invention [0003] The invention ai...
