Description
The present invention relates to roof waterproof, indoor moistureproof engineering belongs to building material field.
In existing technology, roof waterproof still adopts old processing method, promptly adopts the practice of three floors of tarred felt and four floors of tar, be exactly at the on-the-spot kitchen range of lathe turner, heat asphalt blocks more than 200 ℃, then, this deep fat is coated on the roofing of construction place, after sticking linkrusta, on linkrusta, coat deep fat again, on this deep fat face, stick linkrusta again, on the linkrusta surface, be coated with deep fat again, then, stick linkrusta again, be coated with the last layer deep fat at last again.This way is not only outmoded, complex process, also has contaminate environment, easily produces the scald accident, and, there is mistake just not reach the purpose of waterproof slightly, the anti-revisionist rate of this technology can reach more than 50% according to statistics.At present, the report of the existing cold water-proof material of bitumen emulsion, what deliver as asphalt felt-making factories field, Beijing oecoeclades falcata of " worker is built in Dalian " second phase in 1981 publication is exactly an example about the cold water-proof material of loam mould bitumen emulsion.But do not introduce its technology contents in the article, just propose some technological standards of this product.
Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, saves starting material, save energy, reduces labor intensity, environment purification, minimizing accident and guarantee reliable water resistance, specially proposes concrete solution of the present invention.
Design of the present invention is, hot-melt asphalt or heavy oil mix with water under the effect of machinery with the bituminous molten state, is dispersed in the water, forms milk sap, but this milk sap, just can autocoagulation when drop runs foul of each other, and last same water sepn agglomerated together.For making this milk sap become stable, must add tensio-active agent with emulsifying effect, the molecular adsorption of tensio-active agent forms adsorption layer on water and bituminous interface, the interface expansive force of pitch or heavy oil and water is descended.When the tensio-active agent of absorption around pitch or the heavy oil drop reached capacity, its drop surface had just formed layer protecting film, and this protective membrane stops the coalescent of drop, made milk sap stable.Have high dispersiveness according to sodium bentonite, series of characteristics such as high physical and chemical activity, high colloidal stability, strong adsorptivity and high-adhesion can be as the best emulsifying dispersant of making bentonite emulsified asphalt.In addition, wilkinite can expand rapidly after meeting water, and the wilkinite after the aquation is greasy smooth in vain, under the effect of machinery, can be adsorbed on firmly on the interface of pitch or heavy oil milk sap.This is the major reason of product energy prolonged preservation of the present invention, pitch of the present invention be big petroleum pitch of extensibility or heavy oil to add the little pitch of extensibility be base-material, this pitch or and heavy oil product of the present invention is had in non-fragile characteristics in winter.Here its trade mark of petroleum pitch that said extensibility is big generally is meant 60
#, 100
#, 140
#, 180
#With 200
#, the pitch that extensibility is little generally refers to 10

Proposed by the invention a kind ofly use the big petroleum pitch of extensibility or heavy oil to add the little pitch of extensibility be PRL wilkinite emulsive pitch of base-material and preparation method thereof, its composition prescription (weight percent %, down with) be two kinds: be the prescription of base-material and to add the little pitch of extensibility with heavy oil be the prescription of base-material promptly with the big petroleum pitch of extensibility, (being called for short with heavy oil is the prescription of base-material, down together), now be described below respectively, at first illustrate with the big pitch of extensibility (to be generally: 60
#, 100
#, 140
#, 180
#, 200
#) being the prescription of base-material: pitch accounts for 30～50% of total amount, and emulsifying dispersant wilkinite (100～200 order) accounts for 7～17% of gross weight, and water accounts for 33～63% of gross weight.When pitch is measured lower value, the red limit of taking off of its wilkinite, but water is wanted capping; Measure in limited time when pitch, wilkinite is capping then, and water should take off limit.Generally speaking, getting its optimum value is advisable, be that the pitch amount is 43%, wilkinite measures 10%, water measure 47%, under general normal water proof case, all get this proportioning (claiming normal proportioning), but when being coated with oil of the cold end (i.e. the first road oil), then pitch amount and wilkinite amount are all got its upper limit, are carrying out the iron plate roofing when anticorrosion, pitch and bentonitic amount are all got its upper limit, and the amount of water is then taken off limit.With heavy oil is the prescription of base-material: (pitch that extensibility is little can be 10 to pitch
#, 30
#, but be generally 10
#) accounting for 10～17% of gross weight, heavy oil accounts for 25～38% of total amount, and bentonitic amount accounts for 5～9% of total amount, and the amount of water accounts for 36～60% of total amount.When heavy oil content took off limit value, its asphalt content and bentonite content were also all got its lower value separately, but the content of water should be got its higher limit.Generally speaking, be advisable to get its optimum value, be heavy oil account for total amount 31%, pitch accounts for 13% of total amount, and wilkinite accounts for 7% of total amount, and the amount of water accounts for 49% of total amount, when using this heavy oil as the prescription of base-material, must guarantee that the low extensibility bituminous amount and the ratio of heavy oil amount should satisfy about 3: 7, because such base-material that ratio made is equivalent to the big petroleum pitch base-material of extensibility.
