Problems solved by technology

[0002] At present, hydropower projects are developing in the direction of high dams and high water heads, which puts forward higher requirements for the anti-erosion and anti-cavitation performance of the high-speed flow surface. Abrasive materials can no longer meet these requirements well. In addition, a large number of hydropower projects that have been built after long-term operation also have abrasion and erosion to varying degrees. Commonly used repair materials such as high-strength cement mortar and polymer cement mortar are affected by their strength, Performance limitations such as durability and adhesion to base materials also do not lend themselves well to the repair and reinforcement requirements of these buildings

Embodiment Construction

[0012] The raw materials of the epoxy resin mortar provided by the invention are epoxy resin, medium sand, diluent and curing agent.

[0013] The weight ratio of the raw materials can be:

[0014] Epoxy resin: 12%-16%,

[0015] Medium sand: 73%-82%,

[0016] Thinner: 1.5%-2.5%,

[0017] Curing agent: 4.5% -8.5%.

[0018] The preferred weight ratio of each raw material is:

[0019] Epoxy resin: 13.5%-14.5%,

[0020] Medium sand: 76%-79%,

[0021] Thinner: 2%-2.3%,

[0022] Curing agent: 5% -7.7%.

[0023] The further optimized ratio is:

[0024] Epoxy resin: 14.18%,

[0025] Middle sand: 78.36%-76.24%,

[0026] Thinner: 2.13%,

[0027] Curing agent: 5.33%-7.45%.

[0028] E.g:

[0029] Matching 1:

[0030] Epoxy resin: 16%,

[0031] Middle sand: 73%,

[0032] Thinner: 2.5%,

[0033] Curing agent: 8.5%.

[0034] Ratio 2:

[0035] Epoxy resin: 12%,

[0036] Middle sand: 82%,

[0037] Thinner: 1.5%,

[0038] Curing agent: 4.5%.

[0039] Matching ratio three:

[0040] Epoxy resin: 13.5%...

Abstract

In the invention, epoxy, meidum plain emergy, diluent and curing agent are used as raw material, their weight percentage are (wt%): epoxy 12-16, medium plain emergy 73-82, diluent 1.5-2.5, curing agent 4.5-8.5. epoxy is optimum selected A-type E44 epoxy, medium plain emery can be river sand or quartz sand, diluent can be epoxy propane butyl ether, curing agent is optimum selected modified M-phthalic amine curing agent. Modifying method of said M-phthalic amine curing agent is that M-phthalic amine curing agent and monocycle oxo-compound do chemical combining reaction to generate liquid amine compound, then to be modified by acylate.

Description

Technical field [0001] The invention relates to an epoxy resin mortar and a preparation method of the mortar. This mortar is a building material and can be used in hydropower projects, highways, bridges, factories, wharves and other various construction fields, especially for hydropower projects High-speed flow surface coating and repair and reinforcement materials. Background technique [0002] At present, hydropower projects are developing in the direction of high dams and high water heads, which puts forward higher requirements for the erosion resistance and cavitation resistance of their high-speed flow surfaces. High-strength concrete, silica fume concrete and other commonly used anti-scour Abrasive materials can no longer meet these requirements well. In addition, a large number of built hydropower projects have also experienced abrasion and denudation to varying degrees after long-term operation. Common repair materials such as high-strength cement mortar and polymer cemen...
