Hydrophilic abrasion-resistant epoxy mortar material and preparation method thereof

Abstract

The invention relates to a hydrophilic epoxy mortar anti-abrasion material with excellent anti-abrasion performance and unique hydrophilicity and a production method thereof, which is prepared from the following raw materials in parts by weight: 100 parts of epoxy resin , Hydrophilic curing agent 40‑50 parts, corundum 700‑800 parts, additives 5‑10 parts, acetone 50 parts, hydrophilic epoxy mortar anti-abrasion material has excellent wet and underwater bonding strength, corrosion resistance Excellent performance, the curing time of hydrophilic epoxy mortar material at room temperature is 24 hours, the underwater tensile strength > 3MPa, and the underwater shear strength > 18MPa; it is widely used in the field of hydraulic engineering, suitable for reservoir dams, coasts, and tunnels Anti-abrasion protection or structural reinforcement of buildings such as water pipes, pools, aqueducts, and civil air defense projects.

Description

technical field [0001] The invention relates to a hydrophilic epoxy mortar anti-abrasion material with excellent anti-abrasion performance and unique hydrophilicity and its production method, which is suitable for hydropower stations, tunnels, water pipes, pools, aqueducts, civil air defense projects, etc. Leakage and reinforcement of buildings. Background technique [0002] According to "50 Years of Water Machine Abrasion Research and Practice" (published by China Water Conservancy and Hydropower Press), as early as the 1930s, some European and American developed countries such as Switzerland, France, the United States, Germany, and the former Soviet Union carried out a series of sediment In the experimental research of wear, some work has been carried out on metal materials and non-metal materials, surface hardening and surfacing materials, etc. These anti-wear technologies need to do certain heat treatment on the flow parts such as water machines to keep their surfaces dr...

Problems solved by technology

However, the anti-abrasion technology currently developed has a commonality, that is, during the anti-abrasion construction process, it is necessary to ensure that the surface of the water conservancy project flow parts is dry and there is no water.

Otherwise, the anti-abrasion material cannot be well bonded to the wetted parts, and even cannot be constructed
