Abstract
The invention relates to a mortar concrete waterproofing agent and a preparation method thereof. The mortar concrete waterproofing agent is mainly composed of montmorillonite powder, methyl silane, stearic acid, sodium alkyl benzene sulfonate, water glass, hemihydrate gypsum, polypropylene fiber and the like. By using the mortar concrete waterproofing agent, the compactness, impermeability, cracking resistance and durability of concrete are greatly improved.
Description
Technical field
The present invention relates to a kind of mortar concrete water-resisting agent and preparation method thereof, belong to the concrete building material field.
Background technology
Mortar concrete is widely used in the engineerings such as building, water conservancy, road, is involve the interests of the state and the people important material of construction and engineering materials.The tiny pore of inner uniform distribution after the concrete forming; Buildings by concrete makes up will be owing to hydrostaticpressure and capillary action; The infiltration phenomenon appears; Accumulate over a long period, infiltration has very big influence to mortar concrete even building structure, so waterproof has material impact to the building engineering quality.
Present water-resisting agent kind is various in style, and wherein mineral-type water-resisting agent staple has villaumite, chlorine lithium hydrochlorate, vitriol, water glass, zirconium compounds, mineral powder etc.; The staple of organism class water-resisting agent has ester fat acid metal salt, synthetic resins, water soluble resin, various emulsions etc.; Also having developed a kind of swelling agent in recent years is host; The expanded polystyrene veneer water-resisting agent of compound other admixture; But the improper use meeting causes concrete cracking, because there is shortcoming in various degree in existing water-resisting agent, still can not satisfy the water proof anti-seepage needs of construction work.
Summary of the invention
To the problems referred to above, the objective of the invention is to provide mortar concrete water-resisting agent of a kind of density, impermeability, splitting resistance and weather resistance that improves mortar concrete and preparation method thereof.
The present invention realizes through following technical scheme, it is characterized in that: mainly by mainly being made up of montmorillonite powder, methyl-monosilane, Triple Pressed Stearic Acid, sodium alkyl benzene sulfonate, water glass, semi-hydrated gypsum, polypropylene fibre etc.
By its weight part proportioning be: montmorillonite powder 70～90; 0.3～2.0 part of methyl-monosilane; 2～5 parts of Triple Pressed Stearic Acid; Sodium alkyl benzene sulfonate 0.01～0.1 deal; 3.0～10 parts of water glass; 2～6 parts of semi-hydrated gypsums; 5～8 parts of polypropylene fibres.
Its preparation method is: weigh by each composition weight proportion speed; The montmorillonite powder that takes by weighing is placed in the stirrer; Then the methyl-monosilane that takes by weighing, Triple Pressed Stearic Acid, sodium alkyl benzene sulfonate, water glass are successively added in the montmorillonite powder successively and stir; Temperature is controlled in 120 ℃～180 ℃, stirs 1.5h, forms alkaline smectite powder; In the montmorillonite powder powder, add semi-hydrated gypsum, the polypropylene fibre that takes by weighing then, after stirring, promptly get described mortar concrete water-resisting agent.
Embodiment
Take by weighing each component by each composition weight proportioning; The montmorillonite powder that takes by weighing (fineness is more than 300 orders) is placed in the stirrer for 85 parts; Then 1.0 parts of the methyl-monosilanes that takes by weighing, 3 parts of Triple Pressed Stearic Acid, 0.1 part of sodium alkyl benzene sulfonate, 5 parts of priorities of water glass are added in the montmorillonite powder successively and stir; Temperature is controlled in 120 ℃～180 ℃, stirs 1.5h, forms alkaline smectite powder; In the montmorillonite powder powder, add 3 parts of semi-hydrated gypsums, 6 parts of the polypropylene fibres that takes by weighing then, after stirring, promptly get described mortar concrete water-resisting agent.
