The outstanding features such as pitch is used for waterproof and has very long history, and this is because pitch has good water-repellancy and weather resistance, remains the important materials of buildings waterproof so far, and it has, and cheaper starting materials is abundant, easy construction, and water-proof function is strong, the waterproof cycle is long.Domestic modifying asphalt coating is solvent-borne type and water-latex type modified waterproof asphalt material mainly.But due to pitch exist flexible poor, extensibility is low, low temperature is easy to crack, especially hotly drops down cold short shortcoming, therefore in use, the defect of above-mentioned two kinds of modifying asphalt coating various degrees.Wherein emulsifying water bituminous composition making method is loaded down with trivial details, and disadvantage is that film forming compactness is poor, and thus water-repellancy and ageing resistance are all poor because coating is water-based; Solvent-borne type bituminous composition, can not at indoor construction owing to there is a large amount of organism.Particularly use in the kitchen and toilet and buildings of improper ventilation, one is the cycle extending construction operation, and two is cause healthy effect to operating personnel.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide that a kind of safety and environmental protection, water resistance are good, cohesive strength is high, the weather condition of high temperature low temperature can be adapted to, the asphalt waterproof paint for building of ageing-resistant, quality product stable performance.
Another object of the present invention is the preparation method providing a kind of above-mentioned asphalt waterproofing paint simple to operation.
The present invention adopts following technical scheme:
A kind of SBS modified waterproof asphalt material for building, its raw material composition is: pitch: 40-50 weight part, used oil: 15-20 weight part, talcum powder: 10-15 weight part, SBS:2-4 weight part, zinc aluminium alloy powder: 1-5 weight part, myo-Inositol hexaphosphate: 1-3 weight part, Virahol: 1-3 weight part, inferior sodium phosphate: 1-3 weight part, cerous nitrate: 0.2-0.5 weight part, lanthanum nitrate: 0.5-1.5 weight part, C16 alcohol: 0.2-1.5 weight part, glycerine: 0.2-0.5 weight part, polydimethylsiloxane: 0.05-0.2 weight part, benzalkonium chloride: 0.01-0.1 weight part,
Wherein, described pitch is the mixture that 10# pitch and 100# pitch mix according to 1:7 part by weight;
Described talcum powder fineness is between 80-100 order;
The mass percent of each component of described zinc aluminium alloy powder is: Zn:50% ~ 60%, and surplus is Al and inevitable impurity.
Above-described SBS modified waterproof asphalt material for building, its preparation method is:
A, used oil poured into reactor heating, and stirring at low speed, stirring velocity is 80 turns/min, after 180 DEG C, add SBS, increases stirring velocity to 150 turn/min simultaneously, fully stirs more than 30min and all melt to SBS;
B, add 100# and 10# pitch, stir 20min, to all fusings;
C, add talcum powder, increase stirring velocity to 180 turn/min, add zinc aluminium alloy powder, myo-Inositol hexaphosphate, Virahol, inferior sodium phosphate, cerous nitrate, lanthanum nitrate, C16 alcohol, glycerine, polydimethylsiloxane, benzalkonium chloride more successively, stir 20min, obtained dark thick liquid;
D, dark thick liquid poured into scribble in the little iron flask of releasing agent, after room temperature cooling, namely obtain SBS modified waterproof asphalt material for building.
Pitch uses as water-proof material, and what first will solve is that pitch heat drops down the drawback of cold shortness, improves the heat-resisting and resistance to low temperature of pitch.The pitch of different labels has different, and this invention adopts 100# and 10# two kinds of pitches, found through experiments 10# pitch and 100# pitch used in combination best to performances such as heat-resisting cold-resistant, the viscosity of coating according to 1:7 part by weight.
One of altered contents of asphalt waterproofing paint provided by the invention is zinc aluminium alloy powder.Because zinc aluminium alloy powder is uniformly distributed in bituminous coating, substantially increase corrosion resisting property and the ageing-resistant performance of bituminous coating, and also have larger improvement to the physical strength of pitch when the mass percent of Zn is 50% ~ 60% in described zinc aluminium alloy powder, and zinc aluminium alloy powder is comparatively cheap.
One of altered contents of asphalt waterproofing paint provided by the invention is SBS.SBS makes pitch have island structure, greatly strengthen the heat-resisting winter hardiness of pitch, and gives the intensity of pitch excellence.Secondly, must be more for convenience during bitumen construction.Because modifying asphalt yield temperature wants more than 180 DEG C, melting construction is cumbersome, and thus used oil is as softening agent, makes it have lower yield temperature, convenient construction; But too much increase that used oil can make bituminous composition intensity significantly reduce, not anti-extrusion, and thermotolerance is reduced.Adding SBS modification and adding softening agent to the heat-resisting and cold-resistant of pitch is contradiction, suitable proportioning must be found, bituminous composition (as surface temperature 60 DEG C) under weather high temperature just can be made not trickle, it can easily melt construction (as being heated to 120 DEG C) again.Moreover for making pitch bond with base material better, in coating, adding glycerine can keep good viscosity under-10 DEG C of environment.
Talcum powder and bitumen compatibility good, the thermotolerance of Bituminous waterproof coating is beneficial to, and when talcum powder fineness is between 80-100 order best results.
One of altered contents of asphalt waterproofing paint provided by the invention is rare earth nitrate.Cerous nitrate and adding of lanthanum nitrate can strengthen pitch network structure, and increase the flexibility of coating, especially under-25 DEG C of cold condition, bituminous coating embrittlement can not occur, and still has flexibility.In test, modified waterproof asphalt material of the present invention constructs the bituminous coating that obtains after 80 DEG C of thermal ageings of 168 hours, and under-20 DEG C of cold condition, coating does not occur crackle.This illustrates the asphalt waterproofing paint adding cerous nitrate and lanthanum nitrate, and its low temperature flexibility improves greatly, has excellent ageing-resistant performance simultaneously.
Polydimethylsiloxane can make pitch matrix and SBS rubber, mineral filler better combine, thus increases anti-permeability performance, and strengthens intensity and thermotolerance.
One of altered contents of asphalt waterproofing paint provided by the invention is benzalkonium chloride.The favourable fillers dispersed of benzalkonium chloride energy, after paint heating is melted, construction is more even, and greatly can improve the physicals of coating, water resistance is better.
One of altered contents of asphalt waterproofing paint provided by the invention is myo-Inositol hexaphosphate.Adding by myo-Inositol hexaphosphate, make the existing larger intensity of bituminous coating, have again good thixotropic creep effect.Even if, coating stressed larger time (for more than 50% of shearing resistance), have good creep property, and under less External Force Acting, good intensity can be kept again, do not produce obvious creep.So this coating can be well dynamic with building, long-term stressed time can discharge internal stress, slow down stress aging.
One of altered contents of asphalt waterproofing paint provided by the invention is inferior sodium phosphate.By adding inferior sodium phosphate in bituminous composition, under coating being split situation by stamp, well self-closing, oneself can bond again when summer temp height, namely there is the ability of self-healing.
Find in formula development process of the present invention, a small amount of C16 alcohol add the wettability that greatly can improve coating, make solidify after coating evenly densification, become rubber-like snappiness without seam after solidification, jointless water-tight corrosion-proof layer, be continuous closed system, waterproof anti-corrosion performance is superior.Avoid simultaneously the poor compatibility of SBS modified waterproof asphalt material, storage and use time the problem that is easily separated.
The advantage of asphalt waterproofing paint of the present invention is: 1, have broad thermal adaptability, has low temperature flexibility and high thermal resistance; Not embrittlement under the low temperature of-25 DEG C, does not trickle and bubbles under the high temperature of 80 DEG C.2, coating is not containing organic solvent, safety and environmental protection, produce and in construction process environmental sound pollution-free, do not damage workman healthy.3, binding strength of coating is high, and integral waterproofing performance is good.4, preparation method is simple and convenient, quality product stable performance, is applicable to large-scale production.
