Abstract
The present invention discloses a wet-laying and pre-laying waterproof roll which is made by the following processes: dipping and coating a modified asphalt compound on a blank body, controlling the thickness and sizing, coating a membrane, rolling, and the like, wherein the modified asphalt compound contains modified asphalt, a plasticizer, an antioxidant, a functional auxiliary agent and a filling gent. A preparation method of the waterproof roll comprises the following steps: putting substrate asphalt in a reaction pot, adding a thickening agent, irregular polyethylene and styrene-polybutadiene-styrene segmented copolymer, evenly mixing, heating and stirring for 1.5-2 hours, then reducing the temperature to about 180 DEG C, adding padding, the plasticizer, the antioxidant and the functional auxiliary agent into the reaction pot and stirring for 0.5-1h, evenly mixing and modifying, then conveying into a colloid mill for repeatedly milling to the material, then dipping and coating the modified asphalt on the blank body, controlling the thickness, sizing, coating the membrane and rolling, and finally preparing the waterproof roll which has excellent performance and can carry out chemical bonding and physical crosslinking synergism with the concrete, namely, a CPS waterproof roll for short.
Description
Technical field
Patent of the present invention relates to a kind of waterproof roll, particularly can carry out the effect of physical absorption mortise and tenon with concrete and also play chemical crosslinking effect and the secure bond wet shop on concrete simultaneously and overlay waterproof roll and production method thereof.
Background technology
Common waterproofing materials mainly contains coating class and coiled material class and sealing compound, sealing rod class, and what the water-repellent paint consumption was more is polyurethane, polychloroprene latex, polymer cement waterproof paint, the common fault that they all have coating to use: wayward as construction thickness; With the basal plane strong bonded, be subject to the basal plane crack and produce " 0 " flexible cracking; Most of coating is difficult for using in the environment that is subjected to water logging for a long time, also is difficult for using in the place of sun exposure; Particularly solidify the water-repellent paint that uses, construction environment is had relatively high expectations as polyurethanes, smooth, clean, dry as the basal plane requirement, and will repeatedly brush, long construction period easily produces solvent, contaminated environment in work progress.And maximum obstacle is a adhesion problem with basal plane in the waterproofing materials use of coiled material class, as the EPDM rubber waterproof rolling material of the excellent performance that costs an arm and a leg is by gluing and basal plane bonding, the application life of adhesive is shorter, causes that coiled material and basal plane bonding failure produce string water, phenomenon such as leak; SBS, APP modified bitumen class waterproof roll adopt hot melt application and basic unit's bonding, because flame temperature is inhomogeneous, are difficult to guarantee the bond effect of coiled material and basal plane, and hot melt application is easily affected by environment, basal plane humidity or dust are too much, can make bonding failure, produce string water phenomenon; Common wet shop/overlay coiled material can bond with basal plane by cement mortar, form the structure that completely bonds, but this structure that completely bonds is to be formed by physical absorption and mortise and tenon effect, bonding reversible, when being subjected to factor affecting such as the damp and hot circulation of environment, steam swelling, basic unit's motion, full sticking also can degradation failure, finally still can produce string water seepy question; The macromolecular sheet material of compound fabric adopts the cement mortar bonding, and cement mortar is difficult to soak into the sheet surface fabric in the process of bonding, and the corrosion that fabric is subject to cement mortar makes sheet material break away from basic unit, loses the waterproof effect.The defective that these of coating and common coiled material produce in application process has the decision of material self structure characteristics, is their intrinsic defectives, is insoluble.Some open source literatures have reported that some can improve the coiled material of adhesive property in recent years, for example:
1; Chinese patent application number: 01227536.0 title: reverse spreading waterproof roll; open (bulletin) number: CN2487802 applies for (patent right) people: Wang Huirong; address: No. 72 buildings, Lane 243, Longjiang, Taibei City, Taiwan road; invention (design) people: Wang Huirong; enter date: the 2000.01.01 of country; summary: a kind of reverse spreading waterproof roll; mainly comprise a density polyethylene film with high layer and a release liners; but the resin adhesion layer that it is characterized in that a compound pressurized auto-adherence on the density polyethylene film with high layer of this hard; the covering layer of a compound protective coating on the resin adhesion layer; be provided with the release liners of tool protective effect in covering layer; need only during construction anti-subsides of hard density polyethylene film with high layer is laid on single face mould outer rim or the terrace outer rim; tearing release liners; and behind the concreting; the resin adhesion layer is promptly because of producing the chemical reaction effect with concrete; and brute force is attached to the structural concrete face, the aqueous vapor imporosity can be infiltrated, and reach the waterproof effect.

Below we set forth that the present invention is wet to spread/overlay waterproof roll and cement or concrete reaction and bonding mechanism:
The coiled material of the band modified adhesive bed of material wet when spreading or overlaying and the mechanism of cement mortar or concrete bonding mainly comprises aspect two:
1. coiled material and cement slurry generation chemical reaction form cross-linked structure and produce bonding.
When installation of membrane behind the surface of cement slurry, the main component tricalcium silicate of cement begins hydration reaction at normal temperatures and generates hydrated calcium silicate (C-S-H gel) and calcium hydroxide, chemical equation is as follows:
3CaO·SiO2+nH2O＝xCaO·SiO2·yH2O+(3-x)Ca(OH)2
In the CSH gel that hydrated reaction of cement forms, there is the Si-OH group, contain poly-methyl ethoxy silane in the soffit glue-line that contacts with cement slurry, it contacts the back hydrolysis takes place with water, generate hydroxyl with reactivity (group of band * represent can reactive activity hydroxyl)
There is the hydroxyl in the Si-OH group to react in this activity hydroxy and the CSH gel, generates ehter bond, make hydrated calcium silicate gel form chemical bond and firmly be linked at the coiled material top layer.The chemical reaction that these two kinds of groups take place following (part in the circle is represented the ehter bond with the formation of CSH gel):
Form in the process of hydrated calcium silicate in cement solidification, the another kind of modifier in the coiled material gathers the naphthaldehyde sulfonate sodium, can pass through polar group-SO
3 2-With Ca
2+Bond, and Ca
2+The other end be connected with-O-Si-O-key, form an ionic cross-linked structure at last.
In the sizing material owing to there is a functional activity auxiliary agent, their active group can form crosslinked in hydration process with cement, make coiled material and cement slurry or concrete secure bond, this cementation is very firm, be subjected to the environment for use factor of coiled material less, thereby it can be bonded on the basal plane more enduringly, and forms full bonding structure with basal plane, two kinds of modifier in the sizing material thereby the cross-linked structure that forms with the hydrated calcium silicate bonding.
2. coiled material sizing material layer produces physical absorption and mortise and tenon effect and forms bonding with basal plane in the cement solidification process.
Cement slurry is met water generation hydration reaction, and the surface that the hydrated product of generation accumulates in cement granules forms the cohesion film.The surface forms plastic gel film formula cement slurry, guarantees that it has good flowability, can fill up rough defective on the boundary layer microcosmic, makes the complete wetting that forms between coiled material and the cement slurry on the microcosmic by extruding.After glue-line and cement slurry are fully wetting, make glue-line surface tension and cement slurry surface tension approaching, thereby both are combined closely, produce physisorption.
Meanwhile, the moisture gel film layer that deepens continuously carries out chemical reaction, and thin layer is inwardly thickened; Outside the hydrate of external diffusion accumulates in rete, rete is outwards thickened by thin layer.Because moisture infiltrates the speed of rete inside greater than the speed of hydrate to external diffusion, thereby produces osmotic pressure, the saturated solution of the inner hydrate of rete is outwards outstanding to cause rete to break.Breaking of rete makes hydrate contact rapidly and widely with water, reaction is quickened again, generate the hydrates such as hydrated silicate gel, calcium hydroxide and aquation calcium sulfate of more amount, be in contact with one another between them grow into to a certain degree after, slurry can lose plasticity fully, set up the net structure of mutual winding, and constantly produce hydrate in net structure, slurry produces intensity gradually and enters sclerosis formation petrifying water mudstone afterwards.In this process, cement solidification consumes a large amount of water, cause between cement and self-adhesive coiled material forming in the system of partial closure and produce negative pressure, and the curing exotherm of cement, promote the creep of self-adhesive, it is deep in concrete capillary tube or the hole, forms the physics tenon structure, reach reliable bond effect; When the self-adhesion glue-line is penetrated in concrete capillary tube or the hole, increased the area that self-adhesive contacts with concrete, generate more chemical bond on the tenon structure that promotes self-adhesion glue-line and concrete to form, and play " cooperative effect of chemical crosslinking-physics mortise and tenon ", make basal plane and self-adhesive layer form " interpenetrating networks formula " interfacial structure, thereby reach in conjunction with tight, firm, irreversible " skin-type " bond effect technology.It is big inadequately thoroughly to solve modified bituminous pitch coiled material and basal plane adhesion stress, and adhesion stress is not lasting, and problem easily affected by environment has realized that coiled material and basal plane form bonding waterproof construction layer irreversible, not impaired integral type.
Compared with prior art, the present invention has more highlighted its special advantages aspect the concrete interface bonding except having the common wet shop of self-adhesion/overlay coiled material advantages such as " creep crack resistance, self-healing, wet bonding, anti-string water-based, the cheap property of constructing ":
1. bonding force is bigger: it not only has physical absorption and mortise and tenon effect, and produces the chemical bonding effect at the mortise and tenon position of going down to the grass-roots units, and makes collaborative the carrying out of two kinds of effects of mortise and tenon and chemical crosslinking, makes bonding more firm.Even the coiled material top layer is destroyed, the interface of bonding basal plane can be not impaired and produce string water drainage yet.
2. it is irreversible to bond: because there is the chemical bonding effect in region of interest, this bonding is irreversible.Want to take away or peel off waterproofing course, can not accomplish.Unless the destruction coiled material is evened the interface that coiled material and basic unit bond out.
3. bond and temper toughness with gentleness: form flexible adhesion by physical absorption and mortise and tenon effect,, and bond, make boundary layer that enough adhesion strengths be arranged, be highly resistant to the destruction of extraneous stress by the rigidity that chemical bond produces with the stress of elimination owing to basic unit's variation generation.
4. bonding more lasting: physical absorption and mortise and tenon often under the effect that solvent, steam or basal plane expand with heat and contract with cold, produce desorption and take off the process of mortise and tenon, thereby adhesion stress is descended, and lose the waterproof effect of permanent closure.And pass through the bonding that " CPS " technology produces, and owing to have the chemical bonding effect, be not subjected to damp and hot circulation, steam swelling, basic unit's motion effects, and produce adhesiving effect enduringly at the mortise and tenon position, make the waterproof life-span of coiled material identical with body layer.
5. edge fit is more reliable: can directly adopt wet edge fit during wet the shop, it is convenient to construct, and edge fit is firm.
This new invention product can be widely used in waterproof such as roof of buildings, basement, and intensity height, durable is specially adapted to the waterproof of tunnel, civil air defense constructions and installations.
