Description
Technical field
The invention belongs to technical field of buildings, more particularly, to a kind of water proof building exterior wall.
Background technique
External wall is needed by applying the operation settings multiple functions layers such as block, such as waterproof layer, insulating layer, wherein waterproof layer
It is the important component part of external wall, if quality of waterproof layer is poor, after being used for a long time, exterior wall can occur peeling etc. and ask
Topic, makes exterior wall seem mottled unbecoming, while the generation adverse effect of External Wall and exterior wall other function layer, so that other parts
Service life substantially reduce, and then influence building service life.In addition, exterior wall has wear-resisting property certain requirement, avoid
Because scraping leads to the phenomenon that falling off generation, existing exterior coating lays particular emphasis on wear-resisting or waterproof performance one, has both
The exterior coating of good waterproof performance and wear-resisting property does not have, this is just that the use of people brings inconvenience.
Summary of the invention
To solve the above problems, can either guarantee that there is good waterproof action the present invention provides one kind and have good
The water proof building exterior wall of good hard wear resistant performance.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of water proof building exterior wall is applied by water proof building wall slurry and builds obtained after external wall and drying, water proof building
Wall slurry is made by the raw material of following parts by weight, and 2-4 parts of resin, 1-1.5 parts of silane, 5-10 parts of waterproofing agent, stone 600-700
Part, 300-450 parts of sand, 300-400 parts of cement, 70-100 parts of flyash, 180-230 parts of water, 4-6 parts of water-reducing agent.
Preferably, waterproofing agent is made by the raw material of following parts by weight, 120 parts of montmorillonite, 120-130 parts of kaolin, N,
75-90 parts of N- dimethyl oxalamide, 30-45 parts of higher fatty acids, nitric acid -110-130 parts of potassium nitrate mixed liquor and water 200-
250 parts are made.
Preferably, waterproofing agent is made by following methods, it is added at nitric acid-potassium nitrate mixed solution immersion into montmorillonite
It manages and dries, montmorillonite is dispersed in water by treated, and N is added thereto, ball milling after the mixing of N- dimethyl oxalamide
Processing, is heat-treated and is dried after ball-milling treatment and be made modified montmorillonite used, is mixed modified montmorillonite used with higher fatty acids
Higher fatty acid modified montmorillonite is made in refining processing, after then higher fatty acid modified montmorillonite is mixed and is granulated with kaolinite
Waterproofing agent is made.
Preferably, waterproofing agent is made by following methods, nitric acid-potassium nitrate mixed solution is added into montmorillonite in 55-
85 DEG C are dry after immersion treatment 2-2.5 hours, will treated that montmorillonite is dispersed in water, and N is added thereto, N- bis-
With revolving speed ball-milling treatment 3-4 hours of 1200-1700rpm after the mixing of methyl oxalamide, carry out after ball-milling treatment in 90-100
It DEG C is heat-treated and dries and be made modified montmorillonite used, it will be modified montmorillonite used with higher fatty acids progress mixing process at 80-110 DEG C
Higher fatty acid modified montmorillonite is made within 30-50 minutes, then higher fatty acid modified montmorillonite is mixed and made with kaolinite
Waterproofing agent is made after grain.
Preferably, hydrionic concentration is 0.7-1.0mol/L, the concentration of potassium ion in nitric acid-potassium nitrate mixed liquor
For 1.2-1.7mol/L.
Preferably, being crushed to partial size in advance before kaolinite and montmorillonite preparation is 150 microns or less and through 400-450 DEG C
Calcination processing 1-1.5 hours.
Preferably, the higher fatty acids first N with 5~6wt% of higher fatty acids weight, N- dimethyl pyrrole before addition
Alkanone mixing.
Preferably, higher fatty acids is the higher fatty acids of 10 or more carbon number.
Waterproofing agent after higher fatty acid modified montmorillonite and kaolinite mixing granulation by being made in the present invention, montmorillonite conduct
The carrier of higher fatty acids, part action ingredient of the higher fatty acids as waterproofing agent；Since higher fatty acids is hydrophobicity object
Matter, and montmorillonite has preferable hydrophily, it is therefore desirable to it is first hydrophobic modified to montmorillonite progress,
The hydrophily feature for changing performance change montmorillonite by this step, makes it have hydrophobicity feature, while making montmorillonite layer
Spacing expands so that rubber molecule is inserted into the interlayer of montmorillonite, this can also be inserted into for hydrophobic higher aliphatic acid molecule
Convenience is provided between montmorillonite layer.The modification of this step mainly passes through interlayer ion and intermediary water realization between removing montmorillonite layer,
The first step crushes calcining, removes the intermediary water of montmorillonite as possible, then carries out at the removal of impurities of nitric acid-potassium nitrate solution and activation
Reason is removed some impurity being adsorbed between montmorillonite layer using hydrogen ion and is covered using the activation of the compound action of nitric acid and potassium nitrate
The interlayer ion of de- stone, the displacement for making it be easier to that interlayer ion occurs then will treated montmorillonite and N, N- dimethyl second
Diamides ball milling is simultaneously heat-treated, and makes N, and N- dimethyl oxalamide can be grafted onto montmorillonite by replacing montmorillonite interlayer ion
Interlayer on, while also improving the affinity between montmorillonite and montmorillonite layer to rubber, then naturally the advanced rouge of use
Fat acid is further modified treated montmorillonite, since step is directed at the modification of montmorillonite before passing through
Reason, in this step fourth higher fatty acids be not only with treated montmorillonite mechanical mixture before but part butyronitrile rubber
Xanthan molecule chain is grafted to the interlayer of montmorillonite, partially or completely enters the interlayer of montmorillonite, further supports the layer of big montmorillonite
Spacing, while partial higher fatty acid molecule chain is also enclosed in the outside of montmorillonite, and then forms all advanced inside and outside one
The montmorillonite material that fatty acid molecule chain surrounds, by N, N- dimethyl oxalamide with higher fatty acids is secondary strut after illiteracy
There is certain micro- swollen property, and due to hydrophobic characteristic between de- rock layers, meet after water can rapid expanding play waterproof action, this
The higher fatty acids strand being enclosed on the outside of montmorillonite outside also gives better hydrophobicity and waterproofness, makes it without carrying out
Other surface is modified be obtained with good waterproofness and with other organic materials are good mix and be fused together, guarantor
The durability of waterproofing agent made from after card and water proof building exterior wall；It is also same while in order to further improve the workability of material
When be added part kaolinite as filler additive.
Preferably, the partial size of flyash be 100 microns and hereinafter, the partial size of stone be 15 millimeters and hereinafter, sand partial size
It is for 3 millimeters and following.
Preferably, resin is the water-absorbing resin of 50-100 mesh.
Therefore, the invention has the following advantages: the water proof building exterior wall in the present invention is added to waterproofing agent, water suction tree
Rouge, silane and waterproofing agent etc., so that its hydrophilic profile is changed after portland cement reaction, so that the buildings waterproof exterior wall has
Good impervious, waterproof, hydrophobic and have good cracking resistance effect.
