Description
Technical field
The invention discloses a kind of preparation methods of high saturating leakage-repairing glue of waterproof, seepage control, belong to leak repairing material preparation technology neck
Domain.
Background technique
House roof gap is a great problem that China handles house leakproof at present, and building leakage directly influences house
Using function, user security and service life, huge economic losses also are caused to enterprise.In building leakage governance process, seep
It is not a simple process that leakage, which generates, made of this thing gradually accumulates.It needs to carry out the supervision and management of construction, and needs
Special processing is carried out to the place for being likely to occur leakage in building, and carry out comprehensive waterproof work.Building is mended
Leak adhesive has had certain basic condition, and multifunctional house plugging material is a kind of new material developed in recent years, it
The problem of can solve wall and leakage of underground engineering water, has the characteristics that moisture-proof, impervious, leak stopping, bonding.
The house roof of Architecture Design Institute's design will generally increase the processing of two or three layers of waterproof cloth, but due to work progress
It is cumbersome, quality semi-coast will result in roof crack when construction, and the five of original building cost will be spent by handling roof leak
Times or so.In the prior art, processing roof leak is mainly using first prying open gap with awl, then with pitch glass cloth, waterproof
Cloth is poured with cement, and this method is difficult to solve the problems, such as clearance leakage；Also have and house roof or room are carried out using organic bond
Interior gap leak repairing, but sealing effect is poor, it is difficult to so that gap is kept sealing state for a long time.
There are many method of present house leak repairing, and the broken ceramic tile that has tears waterproof layer open, reform waterproof layer, the direct black top having
Etc., these are all some most traditional house leak repairing measures.Broken ceramic tile, reforms the heavy workload of waterproof layer, to building
Destructive big, economic consumption is high, and people also turns from side to side very much；Direct black top, effect is poor, excessively it is a for the moment, water ticktack have out
Begin, and pitch is very smelly when boiling, itself does not also have the performance of environmental protection.So there is an urgent need to a kind of waterproof effects
Environmentally friendly leak repairing material and method good, the duration is long, destructiveness is small.
With emerging in multitude for all kinds of building constructions, building roof, roof tank, floor and waterpipe jointing and municipal administration are net
It is more and more to build to water factory the gap for being possible to occur.It is expected that there are an all kinds of building amounts of thousands of seats in every city every year, and this
The expansion joint waterproof measure on the roof, clear water reserviors, treatment tank of engineerings is produced because of reasons such as construction, quality, material agings a bit
After life phenomena such as rupture etc. and breakage, directly affect using quality, rent situations such as leak is without sealing often occurs, gives
Engineering use and management causes damages, increase trouble.For this purpose, industry develops a kind of leakage-repairing glue, it is coated on gap
Plugging watertight is completed using the characteristic of leakage-repairing glue in place.Existing leakage-repairing glue is mainly the solid paste or artificialization of stationery class
Work high molecular material, leak repairing effect persistence is unsatisfactory, and preparation method is more complex.
And traditional house leakage-repairing glue the problem of can not being further increased there is also waterproofness difference and leak resistance, therefore,
How to improve conventional house leakage-repairing glue waterproofness difference and the shortcomings that leak resistance can not further increase, is provided in the hope of exploring to develop
The house leakage-repairing glue of good comprehensive performance is necessary to leak repairing technical field of material.
