Far infrared coating and preparation thereof

Abstract

The invention relates to a far infrared paint and a method for preparing the same, belonging to the paint field. To solve the technical problem, the invention provides the far infrared paint with low cost and good performance. The far infrared paint is prepared by the following raw materials in percentage by weight: 20 to 60 percent of industrial waste residue containing vanadium, 0 to 10 percent of agglutinant, 30 to 60 percent of caking agent, 0 to 2 percent of dispersant, 0 to 10 percent of chromic oxide, 0 to 10 percent of cobalt oxide, 0 to 10 percent of alumina, 0 to 10 percent of manganese dioxide and 0 to 10 percent of carborundum. The far infrared paint can be used in an industrial boiler and an industrial kiln furnace, has the advantages of high temperature resistance (over 1250 DEG C), good high-temperature conglutination performance, easy porcelain forming, energy economization, etc., and has wide application prospect.

Description

technical field [0001] The invention relates to a far-infrared coating and a preparation method thereof, belonging to the field of coatings. Background technique [0002] Far-infrared paint is a high-temperature energy-saving paint commonly used on industrial boilers and kilns. The black pigment in the pigment is usually composed of fourth-period metal elements such as Co, Ni, Cr, Mn, V, Ti, Fe and other black metal oxides. , generally known as cobalt-based black pigments. At present, the commonly used far-infrared coatings abroad include: ET-4 in the UK, C-10A and G-125 in the United States, CRC 1000 and CRC 1500 in Japan, etc. They are all based on general metal oxides and transition metal oxide systems, supplemented by a small amount of additives, calcined at 1200 ° C, crushed and added with adhesives, and their emissivity can reach up to 0.94. The Enecoat coatings of joint venture companies in the United States, Europe, and Australia use SiC as the base material and ad...
