The problem of position waterproof failure of shape.Meanwhile existing sealing waterproof binding agent production technology is complicated, high temperature resistance, low temperature
Flexible and tearing toughness is difficult to realize be promoted simultaneously.
Summary of the invention
In order to solve existing waterproof binding agent, as the deformation of base material is understood, deformation occurs, and then generates crack, makes
At deformation position waterproof failure the problem of.The present invention provides a kind of high-performance bituminous seal waterproof anti-rotten bonding agent, with tradition
Unlike waterproof binding agent, the present invention, to the cross-linking modified of asphalt, reduces it by modifying agent, crosslinking agent, catalyst
Melt temperature is improved while glass transition temperature, it is possible thereby to construct at normal temperature, and can be protected in -30~80 DEG C of temperature ranges
Hold good flexible working performance, cementability is strong, and permeability resistance is strong, and creep properties is good, ageing-resistant, acid and alkali-resistance, and have it is excellent from
My repair function.The stress of absorbable base material transmitting, prevents waterproof layer cracking, stretches waterproof layer when base material deforms
When, creep material absorbs the stress from base, as deformation occurs for the deformation of base material, avoids the generation in crack, solves
Easily-deformable position waterproof intractable problem.
Meanwhile existing sealing waterproof binding agent production technology is complicated, high temperature resistance, low temperature flexibility and tearing toughness
It is difficult to realize the problem of being promoted simultaneously, the present invention provides a kind of preparation method of the anti-rotten bonding agent of high-performance bituminous seal waterproof.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of anti-rotten bonding agent of high-performance bituminous seal waterproof, is made of following components in parts by weight: asphalt 30~

It is 1~2 part of catalyst, 3~6 parts of solubilizer, 20~40 parts of microdilatancy filler, spare；Successively by 30~60 parts of asphalt, change
Property 20~30 parts of agent, 5~10 parts of softening agent, 3~6 parts of solubilizer, be added stirred tank, be heated to 160~170 DEG C, and constantly stir
Mix to obtain mixture a；
Step 2: after step 1 gained mixture a is stirred 30min, 3~5 parts of the crosslinking agent, the catalyst 1 is added
~2 parts, 3~4h is reacted, mixture b is obtained；
Step 3: step 2 gained mixture b being cooled to 130~140 DEG C, the microdilatancy filler 20~40 is added
Part, constant temperature stirs 1-2h, is cooled to 110 DEG C of discharging packagings to get the anti-rotten bonding agent of high-performance bituminous seal waterproof.
Compared with the prior art, the invention has the beneficial effects that:
1, the anti-rotten bonding agent of high-performance bituminous seal waterproof of the invention is a kind of creepage type waterproof binding agent.With metal,
The substrates such as nonmetallic and coagulation great soil group have good cementitiousness, and the double effects with waterproof, anti-corrosion of metal are suitable for
Municipal works, subway tunnel, dykes and dams, pond, road and bridge, roofing, toilet bath room, inferior position waterproof and seam fill up viscous
It connects.The anti-rotten bonding agent of high-performance bituminous seal waterproof, can be separately as, the filling in gap, crack, crackle as creepage type material
Material can also cooperate waterproof roll to use as coiled material bonding agent.The anti-rotten bonding agent of high-performance bituminous seal waterproof can absorb base
The stress of material transmitting, prevents waterproof layer cracking, and when base material, which deforms, stretches waterproof layer, creep material, which absorbs, comes from base
Stress avoid the generation in crack as deformation occurs for the deformation of base material, solve that easily-deformable position waterproof is difficult to resolve asks
Topic.
2, the anti-rotten bonding agent of high-performance bituminous seal waterproof of the invention avoids the fatigue of waterproof layer, prolongs the service life,
Since waterproof layer is in unstress state in use, thus fast under avoiding waterproof layer high stress or alternate stress state
Fast aging, and then extend the service life of waterproof layer.
3, it since the creep properties of material eliminate base's displacement transfer to the stress of waterproof layer, expands with heat and contract with cold in base
In dynamic changing process, waterproof layer is smaller by the stress variation of tension and compression, will not generate bending failure phenomenon.
4, creep properties waterproof material has pressure-sensitive, all has viscosity and self-healing energy within the entire service life of waterproof layer
Power, when waterproof layer is punctured by external force, breakdown point will not expand, and channeling water phenomenon will not occur for anti-layer bottom, and
And since creep effect can gradually repair breakdown point, active waterproof may be implemented.
5, unlike conventional water-proof adhesive, the present invention is by modifying agent, crosslinking agent, catalyst to asphalt
It is cross-linking modified, improve melt temperature while reducing its glass transition temperature, it is possible thereby to construct at normal temperature, and can -30~
Good flexible working performance is kept in 80 DEG C of temperature ranges, cementability is strong, and permeability resistance is strong, and creep properties is good, and it is ageing-resistant, it is acidproof
Alkali, and have excellent self-regeneration function.
