Embodiment 1

[0022] Select 30.0 kg of cement, 65.0 kg of sand, 2.0 kg of water reducing agent, 5.0 kg of toughening agent, 3.0 kg of water retaining agent, 3.5 kg of expansion agent, and 0.1 kg of damping agent. First put the sand and damping agent into the mixer for mixing, then put the cement, water reducing agent, toughening agent, expansion agent and water retaining agent into the mixer, mix well and pack quantitatively.

Embodiment 2

[0024] Select 70 kg of cement, 70 kg of sand, 0.5 kg of water reducing agent, 0.5 kg of toughening agent, 2.5 kg of water retaining agent, 5.8 kg of expansion agent, and 30.0 kg of damping agent. First put the sand and damping agent into the mixer for mixing, then put the cement, water reducing agent, toughening agent, expansion agent and water retaining agent into the mixer, mix well and pack quantitatively. At the construction site, add 9.5% water according to the weight percentage of the material, and use a forced mixer or manual mixing to form a plastic mortar that can be used.

Embodiment 3

[0026] Select 55.0 kg of cement, 90 kg of sand, 1.5 kg of water reducing agent, 3.0 kg of toughening agent, 0.3 kg of water retaining agent, 2.5 kg of expansion agent, and 20.0 kg of damping agent. First put the sand and damping agent into the mixer for mixing, then put the cement, water reducing agent, toughening agent, expansion agent and water retaining agent into the mixer, mix well and pack quantitatively. Add 11.5% water at the construction site according to the weight percentage of the material, stir it with a forced mixer for 3 minutes or manually mix it into a plastic mortar and use it. Take the conventional plastering method and apply it to the surface of the treated structure. When the initial setting is approaching, the surface should be polished, and the surface can be brushed with an interface treatment agent to obtain better results.

Abstract

The invention provides a cement-based damping wear-resistant material for steel sheet surface construction, comprising the following components by mass: 30-70 parts of cement, 40-90 parts of sands, 0.1-2.0 parts of water reducing agents, 0.5-5.0 parts of toughening agents, 0.3-3.0 parts of water retaining agents, 0.5-6.0 parts of swelling agents and 0.1-30.0 parts of damping agents. The inventionhas the following beneficial effects: (1)improving the damping property of the cement-based wear-resistant material, reducing the damage of the material caused by vibration and lengthening the service life of the material; (2) having good impact toughness to lead the material to have strain hysteresis and ensuring the strain area of the material to be enlarged; and (3) reducing the surface friction coefficient, namely substantially reducing the heat energy generated by friction.

Description

technical field [0001] The invention relates to a damping and wear-resistant material, specifically a steel plate structure that can be used for vibration requirements such as storage bins, hoppers, ore troughs and slag trenches in industrial fields such as metallurgy, electric power, petrochemical, coal and chemical industries. High-performance cement-based damping and wear-resistant material for wear-resistant protective layer. Background technique [0002] In metallurgy, electric power, petrochemical, coal and chemical industries, structures such as storage bins, hoppers, ore troughs and slag trenches are mostly used for storage of materials and treatment of slag water, and their surfaces are in a state of wear and erosion for a long time, causing serious damage to the structures , A wear-resistant protective layer must be set on the surface to play a protective role. Patent [200810100808.1] introduces a cement-based wear-resistant material that can be used for the linin...
