Description
Technical field
The present invention relates to a kind of environmental-friendly construction materials and preparation method thereof, have good antiseep effect.
Background technique
Currently, the whole world has summed up in two for the material of building waterproof: one is rigid antiseep waterproof, one
Kind is flexible barrier leakage waterproof.The rigid antiseep wherein generallyd use is separately to add armored concrete mortar anti-in building basal plane
Water layer.This waterproof layer defective tightness in conjunction with basal plane, and there are molecule gaps for waterproof layer itself, reinforcing bar holds under the action of water
Perishable expansion leads to waterproof layer cracking and loses waterproof and anticorrosion effect.Flexible barrier leakage is organic in building basal plane brushing
Object water-repellent paint forms protective layer.This protective layer not only be easy aging, be layered, fall off, also be easy under the effect of external force by
It destroys, to lose due waterproof anti-corrosion performance.Above two waterproof material is all in building surface brushing waterproof layer.Nothing
By being rigid waterproofing or flexible water, it is easy to layering, cracking, aging, phenomena such as falling off occur, seriously affect antiseep
Quality and effect, the performance of waterproof and anticorrosion can not be really played to building, to reduce the service life of building.
