Description
Technical field
The present invention relates to the binding pastes and preparation method thereof that a kind of wet-laid process is laid with self-adhesive coiled material.
Background technique
The construction quality of waterproofing work directly influences the use or even structure safety of building.With Building technology
Development, the requirement to building waterproof construction quality is also higher and higher, needs to select more excellent waterproof material, use is advanced
Construction technology, with guarantee building waterproof effect and structure safety.Adhesive waterproof coil is a kind of waterproof material, with
Same type of material is compared, and is had many advantages, such as easy construction, good waterproof performance, is focused on environmental protection, application is also more and more extensive.Suitable for industry
With roofing, basement, interior, municipal works and the reservoir, swimming pool and subway tunnel waterproof of civil building, also it is applicable in
In the waterproofing work of timber structure and metal structure roofing.
In building construction process, the laying method of self-adhesive coiled material has dry-laid method and wet-laid process.Dry-laid method is smooth
First brushing base treatment agent repaves the method for pasting self-adhesive coiled material after base treatment agent volatilization is dry in base, is fairly simple fast
Prompt method.But if the adhesion strength of self-adhesive coiled material is not enough or if construction is not firm enough, be easy to appear peeling,
The abnormal phenomenon such as hollowing, or even will appear leakage, so that whole waterproof effect is destroyed, moreover, dry-laid method is laid with self-adhesive coiled material
When be affected by weather and base.Wet-laid process is to use binding paste as base's binder, i.e., first binding paste is poured on
In base, then binding paste is caught up with to walk when being laid with self-adhesive coiled material, after rising and doing solid work, the adhesion strength of self-adhesive coiled material and base
It greatly enhances, moreover, requirement of the wet-laid process to self-adhesive coiled material is relatively low compared with dry-laid method, while self-adhesive coiled material and base
Adhesion strength is much larger than dry-laid method.So wet-laid process using more and more extensive.
The bond effect for the binding paste that existing majority wet-laid process is laid with self-adhesive coiled material is not ideal enough, often makes certainly
Glue coiled material and base adhesive loosely, hollowing phenomenon easy to form, and also the binding paste having is easy to form one layer at base interface
Film, cannot be Nian Jie with base's perfection, and the disengaging of self-adhesive coiled material and base is still easy to appear after use, to influence waterproof effect
Fruit.So facing status, a kind of binding paste that can effectively enhance self-adhesive coiled material Yu base's cohesive force is needed.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides it is a kind of prepare it is simple, easy to use, influenced by weather
The binding paste of wet-laid process laying self-adhesive coiled material that is small, can effectively enhancing self-adhesive coiled material and base's cohesive force and its preparation side

The binding paste squeezed out is managed and recycles, self-adhesive coiled material lap-joint is using additional self-adhesion sealing strip sealing.After air drying, it surveys respectively
Determine the adhesion strength and leakage scenarios of self-adhesive coiled material and base.
The measurement of adhesion strength: after the completion of engineering construction, each in 6 regions respectively to be cut into 5 pieces of samples at random (total
30 pieces of samples), cohesive force pull-out test is carried out in situ, and it is qualification that pull strength, which reaches 5MPa, counts self-adhesive coiled material and base
The qualification rate of layer adhesion strength.Leakage scenarios test: after the completion of engineering construction, 1000 ㎡ conducts are respectively chosen in 6 regions respectively
On-the-spot test area, carries out water storage, depth 3-5cm, storage time 24 hours or carries out water pouring test (water drenching 2h), carries out scene
Breakthrough inspection counts ne-leakage area percentage.
Concrete condition is shown in Table 2:
As can be seen from Table 2, after being constructed using the binding paste that wet-laid process obtained by the present invention is laid with self-adhesive coiled material,
The bonding of self-adhesive coiled material and base is stronger, and the qualification rate of adhesion strength is above 96%, and is laid with using other wet-laid process
After the binding paste of self-adhesive coiled material is constructed, the adhesion strength qualification rate of self-adhesive coiled material and base is only up to 80%.Together
When, after constructing using the binding paste that wet-laid process obtained by the present invention is laid with self-adhesive coiled material, do not occur breakthrough, and adopt
After being constructed with the binding paste that other wet-laid process are laid with self-adhesive coiled material, there is leakage phenomenon, leakage area percentage
Reach 6%.As it can be seen that effect is more after being constructed using the binding paste that wet-laid process obtained by the present invention is laid with self-adhesive coiled material
It is good, it is worth of widely use, there is biggish application prospect.
Finally it should be noted that embodiment is the optimal specific embodiment of the present invention, it is not limited to this
Invention, although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, according to
It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes.All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention
Protection scope within.
