Abstract
The invention relates to a self-adhesion reactive, water-swellable and waterproof sealing material and a production method thereof. Butyl rubber is used as the matrix of the self-adhesion reactive, water-swellable and waterproof sealing material, and other raw materials comprise polyisobutene, amorphous alpha-olefin copolymer, desulfuration gypsum, bentonite, tackifying resin, lithium chloride, calcium chloride, calcium stearate and a crosslinking agent, and counted in parts by weight, the proportions of the components are as follows: 50-100 parts of butyl rubber (IIR), 50-120 parts of polyisobutene, 5-10 parts of amorphous alpha-olefin copolymer, 100-180 parts of desulfuration gypsum, 80-120 parts of bentonite, 12-25 parts of tackifying resin, 0.1-2 parts of lithium chloride, 1-10 parts of calcium chloride, 0.08-1.2 parts of calcium stearate and 0.5-3 parts of crosslinking agent. By adopting the self-adhesion reactive, water-swellable and waterproof sealing material provided by the invention, the utilization range of the solid waste desulfuration gypsum is expanded, the problem that the existing waterproof sealing product cannot generate a chemical crosslinking reaction with concrete is solved as well, the two components are organically combined to turn waste into wealth, and the self-adhesion reactive, water-swellable and waterproof sealing material with a self-recovery function is innovatively provided.
Description
First, technical field
The present invention relates to buildings waterproof field of sealing technology, and in particular to be a kind of self-adhesion reactivity water-swellable waterproof
Encapsulant and its production method.
2nd, background technology
China's power industry is the rich and influential family of coal consumption, and annual Coal-fired capacity accounts for the 60% of total amount, the titanium dioxide of discharge
Sulfur accounts for the 50% of total release, in recent years, with the continuous improvement of National Environmental standard, the discharge to thermal power plant's sulfur dioxide
Concentration there has also been tightened up regulation, and this is greatly reduced the discharge capacity of China's sulfur dioxide.And thermal power plant's application accounts for 80%
Fume desulphurization method above is limestone scrubbing FGD, and this also results in desulfurated plaster becomes the thermoelectricity after flyash
The second largest solid waste of factory, substantial amounts of solid waste desulfurated plaster lack the approach for utilizing, and burden is caused to environment.
All there are leakage problems in all kinds of buildings at present, and seepage is just slowly corroding the safety of building, little to roofing, door and window, wall
The seepage of body, collapses to subway, tunnel even skyscraper greatly, and more prominent is that underground leakage can cause surface collapse,
Building life is reduced, building safety is endangered, but relative to the building accident such as collapse, erosion of the underground leakage water to architectural engineering
It is slow, with certain disguise, its harm is difficult the attention for causing people, has expert to point out underground leakage water to the person
And the potential threat of property safety is bigger, such as take no action to just as having buried a time bomb at one's side.And existing build
(such as waterstop, sealing rod, seal plate etc.) that building waterproofing sealed product is either shaped or indefinite form (such as：Clay, putty
Deng) etc. not with concrete occur chemical crosslink reaction function.
3rd, the content of the invention
It is an object of the present invention to provide a kind of self-adhesion reactivity water-swellable waterproof and sealing material, a kind of this self-adhesion
Reactive water-swellable waterproof and sealing material is used to solving current solid waste desulfurated plaster to be unable to effectively utilizes and existing
Waterproof sealing product is not with the problem that chemical crosslink reaction occurs with concrete；It is a further object to provide this
The production method of self-adhesion reactivity water-swellable waterproof and sealing material.
The technical solution adopted for the present invention to solve the technical problems is：This self-adhesion reactivity water-swellable waterproof sealing
Based on butyl rubber, other raw materials include polyisobutylene, amorphous state alpha olefin copolymer, desulfurated plaster, swelling to material
Soil, tackifying resin, lithium chloride, calcium chloride, calcium stearate, cross-linking agent, are counted by weight, and the proportioning of above-mentioned each component is as follows：
In such scheme, other raw materials also include SAP resins, and its content is 10～50 parts, so be can further improve anti-
Material expand multiple can be increased to 150～300 times by the expansion multiple of watertight closure material.
In such scheme, other raw materials also include butyl reclaimed rubber, and its content is 5～30 parts, can reduce producing into
This.
The production method of above-mentioned self-adhesion reactivity water-swellable waterproof and sealing material：
A. refining glue
(1), by the butyl rubber in raw material, amorphous state alpha olefin copolymer, desulfurated plaster, calcium stearate each component by weight
Amount percentage ratio is kneaded in putting into banbury, melting temperature control at 105～120 DEG C, mixing time 3～8 minutes；
(2), send into mill after elastomeric compound discharging to be radiated, 55 DEG C of roller temperature ＜, 6～10 millimeters of roll spacing；
B. filter glue
Will after bar under the elastomeric compound after radiating send into rubber strainer filter glue, filter screen be 80～100 mesh, 92 DEG C of head temperature；Machine
65 DEG C of body temperature, 40 DEG C of extruder temperature；It is referred to as rubber master batch through the elastomeric compound of this process；
C. mediate
(1) kneading chamber of kneader is heated up to into 70～80 DEG C, then the rubber master batch for having filtered and tackifying resin is put into
Blending 15～30 minutes is mediated in kneader；Segmentation puts into remaining each component in raw material by weight percentage simultaneously；Kneading chamber
125～150 DEG C of temperature, 40～90 minutes kneading times.
(2) SAP resins, are put into and continues to mediate 20～30 minutes kneading temperature controls at 125～150 DEG C.
(3) the kneading room temperature of kneader is down to into 70～80 DEG C, input cross-linking agent continues to mediate blending 10～20 minutes
Afterwards；The screw rod discharge device of Jing kneader bottom filters (filter screen is in 80～100 mesh) discharge.
Beneficial effect：
1st, the present invention has widened the utilization scope of solid waste desulfurated plaster, solves existing waterproof sealing again and produces
Product can not occur the problem of chemical crosslink reaction with concrete, both are organically combined, is turned waste into wealth, carried pioneeringly
The reactivity water-swellable waterproof and sealing material of the self-adhesion with self-regeneration function is supplied.
2nd, the present invention use when with concrete mortar react to be formed completely glue effect, effectively prevent the infiltration of water, even if
There is infiltration situation, as material (bentonite and SAP resins) itself is with 50～300 times of expansion rate, so at this
Bright that certain pressure can be produced and concrete between, in the presence of this pressure, breakthrough is blocked, so as to reach material
Itself is also provided with repair function, and the water for being effectively prevented leakage point runs helter-skelter that to cause waterproof and sealing material integrally to lose function existing
The generation of elephant.
