Description
Technical field
The present invention relates to buildings waterproof fields, and in particular to a kind of to be modified using high molecular polymerization modified fibre
Waterproofing slurry and preparation method thereof.
Background technique
Waterproofing slurry is a kind of bi-component waterproof material for being exclusively used in buildings waterproof, presses one by powder part and liquid material part
Certainty ratio proportion composition, wherein powder is made of cement fine sand and unique active material, and liquid material is then usually by polymer
And auxiliary agent merges, and is painted on cement basal plane after two groups of material mixing and reaches waterproof effect.
Currently, being flooded with a large amount of rigid waterproofing slurry in the market, the type product is because cement largely makes in powder
With when being easy to cause solid film forming, mortar surface has cracked powder, and when carrying out the construction of yin-yang angle, because material accumulation makes to crack
It is particularly acute or even dusting is peeled off, lose waterproof effect；Again because liquid material in contain a large amount of moisture, make its surface strength with
Actual strength promotion after solid is slower, influences subsequent handling construction, schedule delays.
Summary of the invention
To overcome existing technological deficiency, the present invention provides one kind to prevent cracking, dusting, improves the modification of construction efficiency
The waterproofing slurry of fibre modification.
To achieve the purpose of the present invention, it is achieved using following technical scheme:
A kind of modified waterproofing slurry of modified fibre is prepared from the following components based on parts by weight:
Powder: 50 ~ 70 parts of portland cement, 20 ~ 35 parts of quartz sand, 5 ~ 13 parts of silica flour, 2 ~ 3 parts of metakaolin, dry powder
0.1 ~ 0.3 part of water-reducing agent, 0.1 ~ 0.3 part of dry powder defoaming agent, 0.01 ~ 0.05 part of cellulose ether, organosilicon moisture repellent 0.1 ~ 0.3
Part, 0.3 ~ 0.5 part of zinc stearate, 0.1 ~ 0.3 part of glass fibre reinforced modified fiber；
Liquid material: 50 ~ 70 parts of water, 30 ~ 50 parts of lotion, 0.1 ~ 0.3 part of defoaming agent, 0.1 ~ 0.3 part of fungicide, water-reducing agent 0.1 ~ 0.3
Part, 0.3 ~ 0.5 part of antifreeze；

In the present invention, portland cement is inorganic coagulation material, provides due intensity and hardness for waterproof mortar.
Lotion further enhances the intensity and hardness of waterproof mortar as organic cementitious material, while providing for cracking resistance
Certain stress anchoring.
Glass fibre reinforced modified fiber is the main cause that cracking resistance of the present invention improves by force early, using fiberglass reinforced fiber come
The diverging of stress is hindered, prevents " crazing phenomenon " from occurring, while crazing can be prevented to be further changed to crackle, so that waterproof mortar has
There is cracking resistance, since fiber reduces the generation of micro-crack, when early stage is solid, hydrated cementitious shrinks maximum product
Period reduces crackle generation, increases the bond stress with powder, so that mortar is integrally complete after solid, in early days by external force
When, will not because of crackle presence and disperse load, improve its early strength.
Quartz sand and silica flour provide construction smoothness, fluency, and serve as filler, increase compactness, guarantee that product is mixed
Fine and smooth appearance after conjunction.
Metakaolin is high-activity mineral blending material, is the amorphous silicic that ultrafine kaolin is formed by low temperature calcination
Aluminium is reacted with the CH generated in cement hydration process, improves hydration efficiency, improves early strength.
Organosilicon moisture repellent and zinc stearate are provided for waterproof mortar and are hated by organic and inorganic compounding as hydrophober
Water, waterproofness can form hydrophobic membrane on the mortar after solid, and zinc stearate can also improve construction smoothness.
Cellulose ether has certain water-retaining property, improves the operable time of mortar for adjusting product viscosity.
Defoaming agent in dry powder defoaming agent and liquid material is used to reduce the bubble in mortar, leaves when preventing solid because of bubble
Stomata reduces intensity, influences product impermeability.
Antifreeze is used to improve the frost resistance of liquid material, will not be demulsified after making its freeze thawing, and antifreeze boils mostly based on alcohols
Point is lower, when hydrated cementitious heat release, can evaporate rapidly, takes away excessive moisture, improves dry speed.
The water-reducing agent added in dry powder water-reducing agent and liquid material is used to reduce the water consumption of unit cement, improves mobility, changes
Kind application property, while cement dispersibility can be improved, make cement dispersion more evenly, hydrated reaction of cement is more complete.
As one of embodiment, liquid material: powder=1: (2.7 ~ 2.8).
