Description
Technical field
The present invention relates to a kind of water-tight field, particularly relate to a kind of response type composite water-proof sealing compound containing epoxyhydrocarbyl bridging agent and preparation method thereof.
Background technology
At present, differ greatly at PPR or the PVC supplying drainage at building kitchen and toilet passing through floors position and the linear expansivity of concrete floor, under normal temperature, concrete is 1*10
-5/ DEG C, PPR or PVC are (6 ~ 7) * 10
-5/ DEG C, after seasonal cold and hot freeze-thaw cycle several times, supplying drainage and concrete floor junction are easy to occur gap, 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 process.Existing water-tight treatment technology has following several modes:
Modifying asphalt encapsulation process, adopt modifying asphalt to build after hot melt under optimal temperature, complicated operation during this construction technology, temperature controls with coating process very crucial.First, when hot-melt asphalt, temperature control is just right, if temperature is too high, pitch mobility is excessively good, and pitch can be made cannot to adhere to on PPR or PVC, cannot realize sealing, and when temperature is more than 100 DEG C, easily damage; If temperature is too low, pitch and PPR or PVC and concrete adhesion property all can not reach requirement.Second is that when constructing, gimmick wants exactissima diligentia, coating is very even, often to carry out for several times above coating repeatedly, this is because modifying asphalt and PPR or PVC and concrete adhesiving effect not ideal enough, only have and made up by gimmick of constructing.
The process of asphalt mixture sealing compound, what utilize unfilled bitumen, fibre object and solvent is mixed with into sealing compound, sealing cream becomes the character of viscous liquid state under having normal temperature, the envelope that can be directly used in cement and pipeline junction is coated with, 208-WetPatch of such as U.S. Henry company
Polyurethane sealant, take urethane as main component, can directly use at normal temperatures, shortcoming be with PPR or PVC and concrete adhesiving effect not ideal enough, and cannot to construct when basal plane is moist.
Silicone sealant, with water glass and the material such as organosilicon, silicone structure polymkeric substance for main component, with PPR or PVC and concrete adhesiving effect better, but its poor stability, can not be lasting under solar radiation or dampness, easily come off, intensity is also poor, can not meet construction requirement.
Polyacrylic resin sealing compound take crylic acid resin as main component, and its preparation technology's more complicated, needs the modification carrying out high request, be prepared into water-borne acrylic resin, be then prepared into emulsion.Polyacrylic resin sealing compound can be constructed on moisture substrate, but itself and PPR or PVC and concrete adhesiving effect poor.
In sum, also there is many deficiencies in encapsulation process technology when PPR or the PVC supplying drainage of prior art at passing through floors position is constructed, and is badly in need of finding a kind of preparation technology simple, easy construction, water-tight performance is good, and intensity is high, long-lived new waterproof sealing prod.
Summary of the invention

The present invention introduces the bridging agent containing two kinds of different chemical active groups, wherein a kind of group can with cement basal plane generation chemically crosslinked effect, another group can be combined with pitch and rubber and form fine and close spacial framework, the synergy of final physical mortise and tenon and chemically crosslinked, water-proof material is enable to be closely integrated into Unified Global with cement or concrete surface, effectively overcome traditional diadactic structure bonding insecure, cold and heat succeed each other, under drying and watering cycle condition easily and the defect peeled off of basal plane, the water resistance of water-proof material is significantly improved.Meanwhile, waterproof sealing cream of the present invention is water-based, therefore can construct at the basal plane of humidity, convenient to use.
Product performance
Can be there is chemically crosslinked effect again owing to can produce physics mortise and tenon with basal plane in product, be therefore the performance innovative point of this product with the adhesive effect of basal plane excellence.Comparative test result is in table 1:
Table 1
Embodiment 13
After part bridging agent adds sealing compound system, concrete waterproof parameter comparison, the results are shown in Table 2:
Table 2
Under equal addition prerequisite, basically identical to material and cement basal plane cohesive strength, shows that the bridging agent added also has same effect in bonding.And at performance of watertightness, low-temperature performance, anti-channeling water aspect of performance increases, especially low temperature flexibility and anti-channeling water sex expression more outstanding.Through experimental verification, the water-fast persistence of material after adding new bridging agent, can be improved.Because after adding New function auxiliary agent, become after sealing compound is shaping and solid there is elastic sealing ply, can effective the entering or permeate of block water molecule, and there is hydrophobicity performance, therefore more excellent at waterproof and anti-channeling water aspect of performance.
