Embodiment Construction

[0034] The multifunctional waterproof and anti-seepage liquid for cement mortar is composed of stearate solution, modified water glass solution, β-naphthalenesulfonic acid formaldehyde condensation sodium salt and water. The parts by weight and adding ratio of each material are: hard 60-75 parts of fatty acid salt solution, 20-30 parts of modified water glass solution, 5-15 parts of β-naphthalenesulfonic acid formaldehyde condensation sodium salt, and 900 parts of water;

[0035] Described stearate solution is made up of stearic acid, soda ash, ammoniacal liquor (content 28%), potassium hydroxide, sodium fluoride and water, and the parts by weight of each material and adding ratio are: stearic acid 4-4.2 0.2-0.3 parts of soda ash, 3.1 parts of ammonia water, 0.8-0.9 parts of potassium hydroxide, 0.005 parts of sodium fluoride, 90-92 parts of water;

[0036] Described modified water glass solution is made up of polyvinyl alcohol, sodium silicate solution (specific gravity 1.38)...

Abstract

The invention relates to multifunctional waterproof anti-leakage liquid for cement mortar, which is prepared from 60 to 70 weight parts of stearate solution, 20 to 30 weight parts of modified water-glass solution, 5 to 1 weight part of beta-naphthalene sulfonic acid formaldehyde condensation sodium salt and 900 weight parts of water, wherein the stearate solution is prepared from stearic acid, soda ash, ammonia water, potassium hydratem sodium chloride and water, the modified water-glass solution is prepared from polyvinyl alcohol, sodium silicate solution, potassium alum, dibutyl phthalate and water. The invention overcomes the defect of the reduced cement mortar strength of other rigid waterproof agents, has good waterproof effect, avoids the fault caused by the adding amount which can not be easily mastered, and has low price, simple production and low cost. The plastering mortar mixed with the product has excellent spreading performance and work degree of satisfaction.

Description

technical field [0001] The invention relates to an anti-seepage agent, in particular to a cement mortar multifunctional waterproof and anti-seepage liquid and a preparation method thereof. Background technique [0002] In the field of construction waterproofing technology, concrete rigid waterproofing plays an irreplaceable role in flexible waterproofing. Rigid waterproofing mainly relies on the addition of waterproofing agents to cement concrete or mortar to achieve the purpose of self-waterproofing of concrete structures. Its service life can be equal to that of buildings, and it belongs to the nature of "curing the root cause". As far as the current market is concerned, this type of waterproofing agent has many varieties, but its function is single, and it even has certain side effects after use. Such as hydrophobic type, affect the strength of cement; sodium silicate type, poor waterproof effect; polymer resin type, affect the setting speed and so on. Contents of the ...
