Technical field
The present invention relates to the chemistry painting industry field, is a kind of styrene butadiene rubber modified asphalt waterproof paint for building specifically, is mainly used in various construction waterproofing engineerings.
Background technology
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 cheap abundant, the easy construction of raw material, and water-proof function is strong, the waterproof cycle is long.Domestic modifying asphalt coating mainly is solvent-borne type and water-latex type modified waterproof asphalt material.But since pitch exist flexible poor, extensibility is low, low temperature is easy to crack, especially hotly drops down cold short shortcoming, so in use, the defective 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 because coating is water-based, thereby water-repellancy and ageing resistance are all relatively poor; The solvent-borne type bituminous composition can not be at indoor construction owing to there being a large amount of organism.Particularly in the kitchen and toilet of improper ventilation and buildings, use, the one, prolong cycle of construction operation, the 2nd, the operating personnel is caused healthy effect.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of safety and environmental protection, water resistance is good, cohesive strength is high, can adapt to the weather condition of high temperature low temperature, the asphalt waterproof paint for building of ageing-resistant, quality product stable performance.
Another object of the present invention is to provide a kind of preparation method of above-mentioned asphalt waterproofing paint simple to operation.
The present invention adopts following technical scheme:
A kind of styrene butadiene rubber modified asphalt waterproof paint for building, its raw material are formed: pitch: 35-38 weight part, used oil: 10-14 weight part, talcum powder: 20-25 weight part; styrene-butadiene rubber(SBR): 2-4 weight part; aluminium zinc powder: 3-5 weight part; myo-Inositol hexaphosphate: 2-5 weight part; Virahol: 5-8 weight part; inferior sodium phosphate: 2-4 weight part; cerous nitrate: 1.2-1.5 weight part; lanthanum nitrate: 1.5-2.5 weight part; C18 alcohol: 1.2-1.5 weight part; glycerine: 1.0-1.5 weight part; polydimethylsiloxane: 0.2-0.4 weight part; benzalkonium chloride: 0.2-0.4 weight part;
Wherein, described pitch is that 10# pitch and 100# pitch are according to the mixture of 2:5 mixed; The mass percent of described each component of aluminium zinc powder is: Zn:75-80%, surplus is Al and unavoidable impurities.
The preparation method of above-mentioned styrene butadiene rubber modified asphalt waterproof paint for building is:
A, pour used oil into reactor heating, and stirring at low speed, stirring velocity is 50 commentariess on classics/min, adds styrene-butadiene rubber(SBR) after 190 ℃, increases stirring velocity to 180 commentaries on classics/min simultaneously, fully stirs more than the 30min to styrene-butadiene rubber(SBR) all to melt;
B, adding 100# and 10# pitch stir 20min, to all fusings;
C, adding talcum powder, increase stirring velocity to 220 commentaries on classics/min, add aluminium zinc powder, myo-Inositol hexaphosphate, Virahol, inferior sodium phosphate, cerous nitrate, lanthanum nitrate, C18 alcohol, glycerine, polydimethylsiloxane, benzalkonium chloride more successively, stir 20min, make the black thick liquid;
D, the black thick liquid is poured in the little iron flask that scribbles releasing agent, namely get styrene butadiene rubber modified asphalt waterproof paint for building after the room temperature cooling.
Pitch uses as water-proof material, and what at first will solve is the drawback that pitch heat is dropped down cold shortness, improves the heat-resisting and resistance to low temperature of pitch.The pitch of different labels has certain difference, and 100# and two kinds of pitches of 10# are adopted in this invention, found through experiments 10# pitch and 100# pitch and uses performance the bests such as heat-resisting cold-resistant, the viscosity of coating according to the 2:5 mixed.
One of altered contents of asphalt waterproofing paint provided by the invention is the aluminium zinc powder.Because the aluminium zinc powder evenly distributes in bituminous coating, corrosion resisting property and the ageing-resistant performance of bituminous coating have been improved greatly, and the physical strength to pitch when the mass percent of Zn in the described aluminium zinc powder is 75% ~ 80% also has bigger improvement, and the aluminium zinc powder is comparatively cheap.
One of altered contents of asphalt waterproofing paint provided by the invention is styrene-butadiene rubber(SBR).Styrene-butadiene rubber(SBR) makes pitch have island structure, has strengthened the heat-resisting winter hardiness of pitch greatly, and gives the intensity of pitch excellence.Secondly, must be comparatively convenient during bitumen construction.Because the modifying asphalt yield temperature is wanted more than 180 ℃, the fusion construction is cumbersome, thereby used oil makes it have lower yield temperature, convenient construction as softening agent; Can make that bituminous composition intensity significantly reduces, not anti-extruding but too much increase used oil, and thermotolerance is reduced.Adding the styrene-butadiene rubber(SBR) modification and adding softening agent is contradiction to the heat-resisting and cold-resistant of pitch, must seek suitable proportioning, and bituminous composition (as 60 ℃ of surface temperature) under weather high temperature is not trickled, and can it melt construction (as being heated to 120 ℃) easily again.Moreover for pitch is bondd with base material better, in coating, add glycerine and can under-10 ℃ of environment, keep viscosity preferably.
Talcum powder and bitumen compatibility are good, and be beneficial to the thermotolerance of asphalt waterproofing coating, and when the talcum powder fineness is between the 80-100 order best results.
One of altered contents of asphalt waterproofing paint provided by the invention is rare earth nitrate.The adding of cerous nitrate and lanthanum nitrate can strengthen the pitch network structure, increases the flexibility of coating, and especially under-25 ℃ of cold condition, bituminous coating embrittlement can not take place, and still has flexibility.In test, the bituminous coating that modified waterproof asphalt material of the present invention construction obtains through 80 ℃ of thermal ageings of 168 hours after, under-20 ℃ of cold condition, crackle does not appear in coating.This explanation adds the asphalt waterproofing paint of cerous nitrate and lanthanum nitrate, and its low temperature flexibility improves greatly, has excellent ageing-resistant performance simultaneously.
Polydimethylsiloxane can make pitch matrix and styrene-butadiene rubber(SBR), the better combination of mineral filler, thereby increases anti-permeability performance, and strengthens intensity and thermotolerance.
One of altered contents of asphalt waterproofing paint provided by the invention is benzalkonium chloride.Benzalkonium chloride can favourable fillers dispersed, makes that construction is more even after the coating heat fused, can improve the physicals of coating greatly, and water resistance is better.
One of altered contents of asphalt waterproofing paint provided by the invention is myo-Inositol hexaphosphate.By the adding of myo-Inositol hexaphosphate, making the existing bigger intensity of bituminous coating has good thixotropic creep effect again.Even coating has creep property preferably, and under less external force effect, can keep intensity preferably again when big (being more than 50% of shearing resistance) stressed, does not produce obvious creep.So this coating can well move with building, can discharge internal stress long-term when stressed, it is aging to slow down stress.
One of altered contents of asphalt waterproofing paint provided by the invention is inferior sodium phosphate.By in bituminous composition, adding inferior sodium phosphate, split by stamp under the situation in coating, well self-closing, oneself bonds again when summer temp is high, namely has the ability of self-healing.
Find that in formula development process of the present invention the adding of a spot of C18 alcohol can improve the wettability of coating greatly, the coating behind feasible the curing is even compact more, solidifying the back becomes the rubber-like snappiness not have seam, jointless water-tight corrosion-proof layer is continuous closed system, and waterproof anti-corrosion performance is superior.The problem of having avoided the consistency of styrene butadiene rubber modified asphalt waterproof paint poor simultaneously, being separated easily when storage and use.
