Siliceous low-temperature wear-resistant anti-corrosion material

Abstract

The invention discloses a siliceous low-temperature wear-resistant anti-corrosion material. An organic adhesive and a curing agent are subjected to temperature-resistant double modification, and are mixed with high-hardness filler to obtain the siliceous low-temperature wear-resistant anti-corrosion material. The formula of the siliceous low-temperature wear-resistant anti-corrosion material comprises the following components in parts by weight based on 100 weight parts: 35-46 parts of the organic adhesive, 32-36 parts of the curing agent and 23-48 parts of the high-hardness filler. The siliceous low-temperature wear-resistant anti-corrosion material provided by the invention is cured at a normal temperature, is wear-resistant, corrosion-resistant and erosion-resistant, is high in bondingstrength, good in stripping resistance and simple to construct, and can coat any complicated working surfaces, a cured wear-resistant lining is high in integrity and good in thermal shock resistance,and does not expand or contract at the temperature within 150 DEG C, and cracking, deformation and falling are avoided; and by use of the material, the problems of serious equipment abrasion, short service life, frequent maintenance and the like of a powder making system are solved, and meanwhile, series defects of a traditional maintenance method are also avoided.

Description

technical field

[0001] The invention belongs to the technical field of wear-resistant materials, and more specifically relates to a silicon-based low-temperature wear-resistant and anti-corrosion material. Background technique

[0002] In my country's thermal power plants, because the medium conveyed by the flue contains a large amount of acid gas and hard particles, the flue and the corresponding parts are subject to strong corrosion and wear. This is not only due to the need for frequent repairs and replacement of metal materials. Frequent maintenance will come, and it will seriously affect the safe operation of the power plant. Contents of the invention

[0003] The object of the present invention is to solve the shortcomings in the prior art, and propose a silicon-based low-temperature wear-resistant and anti-corrosion material and a preparation method thereof.

[0004] In order to achieve the above object, the present invention provides the following technical solutio...
