Abstract

The invention discloses a hydrophobe type high-strength wear-resistant plate and a manufacturing method thereof, wherein the hydrophobe type high-strength wear-resistant plate comprises the following components by mass part: 50-100 parts of concretes, 0-50 parts of mineral mixtures, 3-20 parts of hydrophobers, 1-5 parts of water reducing agents, 150-300 parts of wear-resistant aggregates, 20-60 parts of steel fibers, 0-10 parts of organic fibers and 20-40 parts of water. The hydrophobe type high-strength wear-resistant plate provided by the invention has the advantages of hydrophobe property, uninflammability, excellent wear resistance, firm combination with substrate, low production cost, simpleness in mounting and repairing, and the like. Meanwhile, the blocking phenomenon of a powder bunker, such as a coal powder bunker, and the like, can be efficiently relieved.

Description

technical field [0001] The invention relates to a hydrophobic high-strength wear-resistant plate and a preparation method thereof. This wear-resistant plate can replace the iron filing mortar, cast stone plate, calendered microcrystalline plate, and cement-based wear-resistant mortar used in large quantities at present, and is used for pulverized coal Such as the surface layer of powder storage bins and lower hoppers that have wear-resistant requirements. Background technique [0002] At present, in coal, coal chemical industry, metallurgy, electric power, building materials and other industries, there are many structures such as pulverized coal and other powder storage bins, hoppers and other structures. In order to protect the basic steel plate or basic concrete from the wear of materials, it is necessary to install wear protection on its surface. layer. At present, the commonly used wear-resistant surface layer includes iron filing mortar, cast stone board, calendered mi...
