Description
Technical field
The invention belongs to building material industry design fields, and in particular to a kind of mortar for clogging perfusion.
Background technology
It was found that a large amount of rain leakage harm occur in many heavy rainfall regional architecture objects in China, seriously affects people and occupy life matter
Amount, moreover, repairing technique is irregular, repairing cost is larger.In a large amount of rainwater leakage phenomenons, exterior wall door and window connection leakage,
Screw hole leakage accounts for larger proportion.The reason of region largely leaks is that raw material impermeability is bad, and filling technique falls behind, and passes
System foamed glue fill process causes outer wall opening risk of leakage.Traditional foamed glue, bonding force is low, and support strength is faint, foaming
The characteristics such as multiplying power is unstable, cause obturator bonding insecure, easily occur filling leakiness or excessively filling cause it is expanded
The problems such as big.And site operation personnel injects the receipts after foamed glue when technique is that cutting is received, and it easily will be empty inside packing material
It attacks exposed, causes to seep water.On the other hand, the mortar of filling perfusion currently on the market is dry mortar material, working performance
Difference shrinks larger, impervious bad, easy cracking.
