specific Embodiment approach 1

[0031] Its specific implementation mode one is:

[0032] 1. Remove impurities from raw materials by filtering;

[0033] 2. Add octadecanoic acid and silane to water respectively for dilution according to the weight ratio of 15%, put the diluted solution into the reactor and heat to 70°C for 30 minutes;

[0034] 3. Add sodium rosinate into the reactor according to 4% of the weight of octadecanoic acid and silane, heat and stir at 70°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0035] 4. Add sodium hydroxide to the reactor according to 10% of the weight of octadecanoic acid and silane, heat and stir at 70°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0036] 5. Add triethanolamine into the reactor according to 0.9% of the weight of octadecanoic acid and silane, cool down to 50°C, stir for 30 minutes, then heat to 80°C, stir for 40 minutes, and cool naturally to form the waterproofing agent.

specific Embodiment approach 2

[0037] Its specific implementation mode two is:

[0038] 1. Remove impurities from raw materials by filtering;

[0039] 2. Add octadecanoic acid and silane to water respectively for dilution according to the weight ratio of 20%, put the diluted solution into the reactor and heat to 80°C for 30 minutes;

[0040] 3. Add sodium rosinate into the reactor according to 3% of the weight of octadecanoic acid and silane, heat and stir at 80°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0041] 4. Add sodium hydroxide to the reactor according to 15% of the weight of octadecanoic acid and silane, heat and stir at 80°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0042] 5. Add triethanolamine into the reactor according to 0.7% of the weight of octadecanoic acid and silane, cool down to 60°C, stir for 30 minutes, then heat to 90°C, stir for 40 minutes, and cool naturally to form the waterproofing agent.

specific Embodiment approach 3

[0043] Its specific implementation mode three is:

[0044] 1. Remove impurities from raw materials by filtering;

[0045] 2. Add octadecanoic acid and silane to water respectively for dilution according to the weight ratio of 16%, put the diluted solution into the reactor and heat to 75°C for 30 minutes;

[0046] 3. Add sodium rosinate into the reactor according to 3.5% of the weight of octadecanoic acid and silane, heat and stir at 75°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0047] 4. Add sodium hydroxide to the reactor according to 12.5% ​​of the weight of octadecanoic acid and silane, heat and stir at 75°C for 30 minutes, and the stirring speed should not be lower than 300 rpm;

[0048] 5. Add triethanolamine into the reactor according to 0.8% of the weight of octadecanoic acid and silane, cool down to 55°C, stir for 30 minutes, then heat to 85°C, stir for 40 minutes, and cool naturally to form the waterproofing agent.

Abstract

The invention discloses a novel process for producing a mortar concrete waterproofing agent. The process comprises the following steps of: diluting octadecanoic acid, silane, sodium abietic acid, sodium hydroxide, triethanolamine and water serving as major raw materials in the ratio of 100:(15-20):(0.9-1.6):(3-6):(0.21-0.36); adding in sequence; heating, and uniformly stirring; and cooling to obtain light yellow liquid. The invention has the advantages that: the produced waterproofing agent has high waterproofing performance and anti-seepage performance on mortar and concrete, the waterproofing service life is greatly prolonged, the ageing resistance of mortar and concrete is enhanced, the service life of an overall reinforced concrete building is prolonged, and the process is nontoxic and is environmentally-friendly in the producing and using processes.

Description

technical field [0001] The invention relates to a production process of a novel mortar concrete waterproofing agent. Background technique [0002] At present, linoleum, paste and various waterproof coatings are widely used in building waterproofing projects in China, which have short service life, easy aging, high cost, limited range of use, complicated construction, toxicity, and serious environmental pollution. shortcoming. Contents of the invention [0003] The purpose of this invention is to provide a new production process for mortar concrete waterproofing agent, which overcomes the above-mentioned problems existing in the existing waterproofing technology. The waterproof service life enhances the anti-aging ability of mortar and concrete, and enhances the overall service life of reinforced concrete buildings. It is non-toxic and does not pollute the environment during production and use. [0004] In order to achieve the above-mentioned design purpose, the technical...
