Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of novel building water-proofing material and preparation method thereof.
Background technology
The material for being presently used for building waterproof sums up and has in two nothing but：One is rigid waterproofings；One is flexibilities
Waterproof.The rigid waterproofing wherein generally used is separately to add armored concrete mortar waterproof layer in building basal plane.This waterproof layer
With basal plane combination defective tightness, and there are molecule gaps for waterproof layer itself, and reinforcing bar easily corrodes expansion under the action of water, causes
Waterproof layer cracking and lose waterproof and anticorrosion effect.Equally, the flexible water generally used at present is painted in building basal plane
Machine object water-repellent paint forms protective layer.This protective layer is not only easy aging, is layered, falls off, and is also easy under the effect of external force
It is destroyed, to lose due waterproof anti-corrosion performance.Above two waterproof material is all in building surface brushing waterproof layer.
In this way, either rigid waterproofing or flexible water, cannot all be combined into unified entirety with building basal plane.Therefore, hold very much
Easily there is layering, cracking, aging, phenomena such as falling off, has seriously affected the quality and effect of waterproof, building can not really have been risen
To the performance of waterproof and anticorrosion, to reduce the service life of building.
Polyurethanes water-repellent paint in waterproof material, using polyurethane as basis, the additives such as coal tar and pitch
It is made, this kind of material film is fine and close, and water resistance is good, but contains many toxic solvents, and smell is larger when construction.And polymer water
Cement-base waterproof coating, this water-repellent paint are the water-repellent paints being combined by organic liquid material and inorganic powder, polymer it is soft
Property and the rigidity of cement became one so that it shows excellent, and asepsis environment-protecting in terms of impervious and stability, but cost
Higher, preparation method is complex.
Publication No. CN105778857A discloses a kind of self-adhering-type waterproof material and its preparation method and application, described
Tack waterproof material is made of the raw material of following mass percent：90# pitches 40%, 10# pitches 3%, machine oil 12%, rubber powder 8%,
1401#SBS3%, SBR6%, mountain flour 28%；The preparation method of the tack waterproof material, includes the following steps：1) formula is pressed to claim
Take each raw material；2) it is pumped into machine oil, 90# pitches and 10# pitches 3% into vacuum kettle, is warming up to 140 ± 5 DEG C, stirring dehydration
30min；3) 1401#SBS is added at 160 ± 5 DEG C, stirs 10min, SBR is added in batches, is warming up to 180 DEG C, insulated and stirred
30min；4) rubber powder is added under the conditions of 170 ~ 180 DEG C, under the conditions of 180 ± 5 DEG C, timing insulated and stirred 3h；5) mountain flour is added,
1h is stirred, material temperature is adjusted and takes out material production.Publication No. CN107541083A discloses a kind of asphalt waterproofing material and its preparation
Method, the waterproof roll and preparation method thereof comprising the asphalt waterproofing material, the asphalt waterproofing material is mainly by following weight
The raw material of part is prepared：20-30 parts of 90# pitches, 10-15 parts of 10# pitches, 6-10 parts of softening oil, 12-18 parts of rubber, SBS-
0.5-1 parts and 30-40 parts of talcum.The waterproof roll is mainly prepared by tire base fabric and above-mentioned asphalt waterproofing material.More than
There is this not lasting waterproof effect, preparation process complexity, the higher disadvantage of cost in two kinds of prior arts, therefore be not suitable for industry
Change large-scale production.
In summary, it is therefore desirable to a kind of better waterproof material, to improve the deficiencies in the prior art.
