Abstract
The invention aims to provide a modified emulsified asphalt waterproof sealant and a preparation method thereof. The modified emulsified asphalt waterproof sealant comprises asphalt, a modifying agent, an emulsifying agent, a thickening agent and water. In a formula system of the modified emulsified asphalt waterproof sealant, more modifying agent in an appropriate amount is adopted than that of the prior art, so that a rubber-asphalt mixture can achieve a good emulsifying effect, the elasticity and strength of a dried sealing layer are greatly improved, and the sealing effect can be better and lasting; and a large amount of the thickening agent is used to adjust the appropriate viscosity of a modified emulsified asphalt waterproof sealant system, so that the modified emulsified asphalt waterproof sealant can be well adhered to the surface of a relatively smooth polypropylene random copolymer (PPR) or polyvinyl chloride (PVC) pipe to well seal the connection part of a PPR or PVC water supply and drainage pipe and a concrete base.
Description
Technical field
The present invention relates to the water-tight field, relate in particular to a kind of modified emulsifying asphalt waterproof sealing cream and preparation method thereof.
Background technology
At present, differ greatly at the PPR at building kitchen and toilet passing through floors position or the linear expansivity of PVC supplying drainage and concrete floor, concrete is 1 * 10 under the normal temperature
-5/ ℃, PPR or pvc pipe material are (6～7) * 10
-5/ ℃, through behind the seasonal cold and hot freeze-thaw cycle several times, supplying drainage and concrete floor junction are easy to occur the slit, therefore, during the construction of building kitchen and toilet water supply and sewerage pipeline, when passing through floors position PPR or the construction of PVC supplying drainage, need to carry out water-tight and process.Existing water-tight treatment technology has following several modes:
The modifying asphalt encapsulation process adopts modifying asphalt to build after the hot melt under optimal temperature, complicated operation during this construction technology, and temperature control is very crucial with coating process.At first, in the time of hot-melt asphalt temperature control just right, if temperature is too high, the pitch flowability is excessively good, meeting so that pitch can't adhesion with PPR or pvc pipe material on, can't realize sealing, and when temperature during above 100 ℃, easy damage; If temperature is too low, pitch and PPR or pvc pipe material and concrete adhesion property all can not reach requirement.The secondth, gimmick is wanted exactissima diligentia during construction, coating is very even, often will carry out above for several times repeatedly coating, this is because modifying asphalt and PPR or pvc pipe material and concrete adhesiving effect are not ideal enough, only has by the construction gimmick to remedy.
Asphalt mixture sealing compound is processed, utilize the sealing compound that is mixed with into of unfilled bitumen, fibre object and solvent, sealing cream has the character that becomes the thick liquid state under the normal temperature, the envelope that can be directly used in cement and pipeline junction is coated with, such as the roof leakage maintenance product of 208-Wet Patch plate of U.S. Henry company.Such sealing compound, but such sealing compound has used the organic solvent of low volatility as solvent, time of drying is slow, often needs above time fortnight could drying, and in the situation that the basal plane humidity because can't adhere to basal plane, and can not construct; And because main component is pitch and fibre object to be formed, dry afterwards sealing ply does not have elasticity, and intensity is relatively poor, not durable.
Polyurethane sealant take urethane as main component, can directly use at normal temperatures, and shortcoming is not ideal enough with PPR or pvc pipe material and concrete adhesiving effect, and can't construct when basal plane is moist.
Silicone sealant, take materials such as water glass and organosilicon, silicone structure polymkeric substance as main component, better with PPR or pvc pipe material and concrete adhesiving effect, but its poor stability, can not be lasting under solar radiation or dampness, easily come off, intensity is also relatively poor, can not satisfy construction requirement.
Polyacrylic resin sealing compound, take crylic acid resin as main component, its preparation technology's more complicated need to be carried out the modification of high request, is prepared into water-borne acrylic resin, then is prepared into emulsion.Polyacrylic resin sealing compound can be constructed at moist basal plane, but itself and PPR or pvc pipe material and concrete adhesiving effect are relatively poor.
In sum, also there are many deficiencies in the encapsulation process technology of prior art when the PPR at passing through floors position or the construction of PVC supplying drainage, is badly in need of finding a kind of preparation technology simple, easy construction, the water-tight performance is good, and intensity is high, long-lived new waterproof sealing prod.
Summary of the invention

Asphalt emulsifier is a kind of tensio-active agent, and basic effect is exactly the surface tension that reduces water, thereby rubber asphalt compound particles and water are coupled together.Rubber asphalt mixture and water objectionable intermingling, directly the rubber asphalt mixture is distributed to and needs to overcome huge interfacial tension in the water, the energy that applies is very large, and the specific surface area that is dispersed into very little particle is very large, so that the rubber asphalt emulsifying mixture system that produces has very high energy state, so be difficult to stable storage, must reduce the surface tension of water when therefore preparing the rubber asphalt emulsifying mixture.
In general, increase the interfacial tension that emulsifying agent can reduce water and rubber asphalt mixture, thereby reduce the energy state of emulsion, increase the stability of emulsion.But contriver's discovery only increases the stability problem that the ratio of emulsifying agent can not solve emulsion fully, the contriver is through great many of experiments, find to cooperate thermoplastic elastomer class asphalt modifier or the rubber pitch modifier of sufficient quantity, can obtain better emulsifying effectiveness.Therefore, the present invention has adopted thermoplastic elastomer asphalt modifier or the rubber pitch modifier than the more sufficient quantity of prior art, so that the rubber asphalt mixture can be realized the good emulsifying effect, and so that the stability of whole emulsion is better, more be convenient to store, and so that the sealing ply after the construction can be dry rapidly, a few hours just can meet the demands after the general construction, have increased the facility of construction; Simultaneously, find through overtesting, the ratio of rubber modifier promotes, also so that the combination of rubber asphalt emulsifying mixture system must be better, increased modified emulsifying asphalt waterproof sealing cream with respect to the adhesiving effect of PPR or pvc pipe material, concrete surface, elasticity and the intensity of dry rear sealing ply have greatly been improved, so that sealing effectiveness can be more good and lasting.
Adopted relatively large thickening material in the formula system of the present invention, the main purpose of using thickening material is in order to adjust the viscosity of suitable modified emulsifying asphalt waterproof sealing lotion system, so that modified emulsifying asphalt waterproof sealing cream can be good adhere on more smooth PPR or the pvc pipe material surface, realize the sealing good to PPR or PVC supplying drainage and concrete floor junction.
Among the formula system of the present invention, can also add a certain amount of toughener, promote the tensile strength of whole sealing compound system by toughener.
