Abstract
A water-proofing agent for mortar and concrete adopts cocoanut oil as main raw material compounded with soap, pllyvinylalcohol, methylcellulose, stearic acid, ammonia water and certain chemical additives. When applying, 1 kg water-proofing agent is diluted with water to 20 kg, then mix diluted water-proofing agent, cement and sand according to the proportion 0.5:1:2.5, no more water is added, the blended material can be directly used. When pouring concrete, the diluted water-proofing agent is used instead of water. This water-proofing agent is easy to operate, good in aging resistance property, no pollution to environment etc.
Description
The present invention belongs to building material field, is to belong to mortar and concrete admixture series.
In recent years, mortar and the development of concrete admixture are rapidly, because admixture can improve mortar and concrete performance, as flowability, plasticity-, density, frost resistance, can also obtain effects such as early strong, fast hard or slow setting, for the reform of concrete construction process provides favourable condition, so, concrete admixture more and more comes into one's own, and uses also more and more general.
The purpose of this invention is to provide a kind of novel water-resisting agent, this water-resisting agent superior performance, resistance to deterioration is good, heat resistance is superior, and cheap, can replace other similar water-resisting agent.
It is main raw material that the present invention mainly adopts Oleum Cocois, and adding soap, polyvinyl alcohol, methylcellulose gum, stearic acid, ammoniacal liquor and some other chemical additives are formulated.Concrete proportioning is as follows:
Oleum Cocois 50kg
Methylcellulose gum 3.5-4.0kg
Stearic acid 1.3-1.5kg
Ammoniacal liquor 1.0-1.1kg
Glycerine 0.5-0.6kg
Hydrochloric acid 0.3-0.4kg
Formaldehyde 0.3-0.4kg
Polyvinyl alcohol 5.0-6.0kg
Sodium dodecylbenzene sulfonate 0.5-0.6kg
Water glass 0.5-0.6kg
Soap 14-16kg
Clear infusion 0.8-0.85kg
Deicing fluid 0.5-0.6kg
Hardening accelerator 0.65-0.7kg
Wherein clear infusion, deicing fluid and hardening accelerator can be selected to add according to the needs of engineering.This water-resisting agent is a kind of water-resisting agent of organic and inorganic compounding, the effect of organic materials and inorganic materials is organically combined, bring into play a kind of advantage separately, by the water-resisting agent that materials such as being used as dispersion agent, intensifier, stablizer, emulsifying agent, reductive agent, tensio-active agent, softening agent, thickening material, vehicle, catalyzer, tackiness agent and membrane-forming agent is composited, has the cohesive strength height, good water-proof effect, the advantage that weather resistance is good.
Preferred version of the present invention is:
Oleum Cocois 50kg
Methylcellulose gum 3.34kg
Stearic acid 1.376kg
Ammoniacal liquor 1.032kg
Glycerine 0.516kg
Hydrochloric acid 0.334kg
Formaldehyde 0.344kg
Polyvinyl alcohol 5.16kg
Sodium dodecylbenzene sulfonate 0.516kg
Water glass 0.516kg
Soap 15kg
Clear infusion 0.86kg
Deicing fluid 0.516kg
Hardening accelerator 0.688kg
Wherein clear infusion, deicing fluid and hardening accelerator can be selected to add according to the needs of engineering.
Above-mentioned materials is mixed stirring can obtain water-resisting agent of the present invention.
Need when using water-resisting agent to be principle as the dilution water-resisting agent of 20kg according to 1kg water-resisting agent thin up.Can use after the stirring.
This water-resisting agent is widely used in inside and outside waterproof, antiseepage, the protection against the tide of the new and old engineering of masonry, concrete and concrete structure.As tunnel, underground works, bridges and culverts, water reservoir, bathing pool, kitchen, toilet etc.The waterproof that can also be used for roof, roof, canopy face replaces traditional malthoid structure.
Water-resisting agent after the dilution can directly mix use with cement, sand, does not need to add water again, according to the water-resisting agent after the dilution: cement: the mixed of sand=0.5: 1: 2.5.Replace water to get final product with the water-resisting agent after the dilution during deposit concrete.
Through test, this new water repellent meets national standard fully, test result such as following table 1:
