Background
The rubber waterstop utilizes the characteristics of high elasticity and compression deformability of rubber, and the cow generates elastic deformation under various loads, so that effective firm sealing is realized, and the problems of water leakage and water seepage of a building structure are prevented. It is mainly used for foundation engineering which is arranged in construction joints, joints and deformation joints when concrete is cast in situ and is integrated with a concrete structure. The waterproof effect of the rubber waterstop depends on the bonding effect of the waterstop and concrete, and the rubber waterstop is easy to generate seepage under the condition of water-stop stress and finally loses the waterproof effect. The waterproof mechanism of the self-adhesive water stop belt is to utilize the effective bonding of a self-adhesive layer in the water stop belt and concrete to seal a water seepage channel of the water stop belt, so that the waterproof function is realized, such as self-adhesive layers of butyl putty and modified asphalt. The adhesive force between the self-adhesive layer and the concrete is originated from secondary bonds such as van der Waals force or hydrogen bonds between molecules, and is a physical acting force. Over time, the oil substances are volatilized, and the small molecules are migrated, so that the bonding force between the interface of the concrete and the oil substances is reduced sharply.

Fig. 1 is a schematic structural view of the uncovering-free rubber water stop provided by the utility model.
Detailed Description
The following will explain the structure and the working principle of the reactive polymer self-adhesive waterproofing membrane with self-healing function in detail with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 1, the utility model provides a structure diagram of a take-off-free rubber water stop. The structure of the rubber water stop belt comprises a rubber base material 1, a middle high polymer self-adhesive layer 2 adhered to one side surface of the base material and an isolating layer 3. The rubber base material can be a common water stop belt, including a buried water stop belt, a back-attached water stop belt, or common rubber water stop products such as an expansion joint, a deformation joint and the like.
The preparation method of the uncovering-free rubber water stop belt comprises the following steps:
the first step, the preparation of the rubber base material comprises the steps of producing the rubber base material with the thickness of 8-10 mm by utilizing the traditional extrusion process according to the rated component proportion;
and secondly, preparing the high-molecular self-adhesive layer, wherein the preparation method comprises the following steps: firstly, adding softening oil, tackifying resin, a filler and an antioxidant into a reaction kettle, heating, controlling the temperature at 170-180 ℃, and simultaneously starting a stirrer for stirring; after the materials are completely melted, adding a self-adhesive layer main body material thermoplastic elastomer, keeping the temperature at 170-190 ℃, and after the materials are completely melted, keeping the temperature at 160-170 ℃ and continuously stirring for 1.0-1.5 h to form the high-molecular self-adhesive;
thirdly, the pretreatment process of the isolating layer comprises the following steps:
under the condition of 100-120 ℃, placing natural zeolite, metakaolin, wollastonite inorganic particles and stearic acid into a high-speed grinding machine, blending at a high speed for 15-20 min, and cooling for later use; in a high-speed grinding machine, the surface of the inorganic particles is activated and reacts with stearic acid, and the surface of the inorganic particles is provided with functional groups capable of reacting with the self-adhesive layer, so that organic combination with the self-adhesive layer can be realized;
fourthly, after the self-adhesive is cooled to a proper temperature, coating a macromolecular self-adhesive layer with the thickness of 0.5-0.8 mm on the upper surface of the prepared waterproof layer, and covering an isolation layer with the thickness of 2.0-3.5 mm and formed by grinding natural zeolite, metakaolin, wollastonite inorganic particles and stearic acid; extruding the three materials by a double metal roller, thermally compounding, molding and rolling to obtain the uncovering-free rubber water stop.
When the rubber water stop is used, the natural zeolite and metakaolin in the isolation layer can participate in the cement hydration process. The specific reaction is as follows:
the natural zeolite begins to decompose in the high alkaline solution in the lattice structure
3+Si-O-Si3+And 6OH-Reaction to form 2[ SiO (OH)3]-
3+Si-O-Al3+And 7OH-Reaction to form [ SiO (OH)3]- And [ Al (OH) ]4]-
Depolymerized [ SiO (OH) ]3]-And [ Al (OH) ]4]-Enter into solution and react with Ca2+Combined to form Calcium Silicate Hydrate (CSH) and Calcium Aluminate Hydrate (CAH), reducing Ca (OH) in the liquid phase2The concentration produced CSH and CAH gels that contributed significantly to the intensity. In addition, because the internal pores of the internal grid-shaped structure of the natural zeolite have huge internal surface energy and strong hydrophilicity, the internal pores absorb mixing water, thereby overcoming the defect of concrete bleeding to increase the viscosity of the concrete and further improving the interface of the high-molecular self-adhesive layer-concrete. When water is needed in the continuous hydration process of the cement, the water adsorbed by the cement can be gradually released, so that the cement can be self-maintained; meanwhile, self-vacuum action is generated inside the self-adhesive layer, so that the self-adhesive layer and the concrete interface are contacted more closely, and finally, the two interfaces are condensed into a compact whole.
The anhydrous aluminum silicate as the active component in the metakaolin and the calcium hydroxide in the hydration of the cement generate hydrated gehlenite and secondary C-S-H gel with gel property, and the hydrates continuously grow in the later period, thereby obviously enhancing the strength between interfaces.
The reason why wollastonite can be used as an interface enhancer is that it has a specific structure. Wollastonite is a natural chain metasilicate mineral with the structural formula of Ca3 (Si 3O 9) and SiO4Skeleton chain and CaO6The complex single chain formed by the planar column is the basic unit of the wollastonite crystal structure. When the wollastonite powder with the high length-diameter ratio (15-20: 1) is crushed into fine particles, the acicular shape is still kept. The wollastonite powder can react with the cast-in-place concrete chemically, but not all wollastonite participates in the hydration process of cement, and more wollastonite crystals still exist at the later stage of cement hydration, and are dispersed between the interface of the wollastonite powder and the interface of the cement in a net form to play a role in reinforcing ribs, so that the wollastonite powder can prevent the development of micro cracks in the cast-in-place concrete when being subjected to the action of external force, and has a mechanical reinforcing function.
