Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more apparent, the present invention is further described in detail below with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A rear-buried waterstop anchoring agent comprises raw material components of epoxy resin, fine sand, an inorganic cementing material, aluminum silicate, nitrile rubber, nano calcium carbonate, calcium powder, hydroxypropyl methyl cellulose, fiber, a silane coupling agent and an amine accelerator;
the weight ratio of each component is as follows:

The calcium powder comprises heavy calcium powder and light calcium powder, and the weight ratio of the calcium powder to the light calcium powder in the rear buried waterstop anchoring agent is as follows: 3.0 to 7.0 percent of heavy calcium powder and 3.0 to 7.0 percent of light calcium powder.
The fiber comprises lignocellulose and polypropylene fiber, and the weight ratio in the rear buried water stop anchoring agent is as follows: 0.3 to 0.6 percent of lignocellulose and 0.3 to 0.6 percent of polypropylene fiber.
Preferably, the weight ratio of each component is as follows:
35.0% of epoxy resin, 10.0% of fine sand, 34.0% of inorganic cementing material, 2.0% of aluminum silicate, 0.5% of nitrile rubber, 2.5% of nano calcium carbonate, 5.0% of heavy calcium carbonate powder, 5.0% of light calcium carbonate powder, 1.0% of hydroxypropyl methyl cellulose, 0.5% of wood fiber, 0.5% of polypropylene fiber, 2.0% of silane coupling agent and 2.0% of amine accelerator.
The silane coupling agent is suitable for surface modification of a filler with high silicate content, and for an anchoring agent taking epoxy resin and portland cement as main components, strong bonding is promoted or established between the water stop and a deformation joint, and the bonding force between the epoxy resin and the water stop and the deformation joint can be effectively improved, so that the bonding between the water stop and the deformation joint is tighter.
The lignocellulose and the polypropylene fibers have high fiber modulus values and strong extension force, have effective stress distribution and crack resistance functions, can effectively prevent brittle fracture, and play a role in toughening and crack resistance. In addition, because the fiber has certain length, and the lignin fiber and the polypropylene fiber respectively take the fiber size of different length, in anchor agent forming process, link together after the dispersion, it is stronger to use tensile strength for alone, can reduce the influence to the waterstop because of temperature stress and shrinkage stress in the deformation joint later stage well.
Because the fibers are irregularly distributed in the forming process of the anchoring agent and are randomly overlapped and mixed to form a fiber network, when the fiber network is applied between the water stop and the deformation joint, the fiber network can well play a role of a reinforcing rib, effectively overcomes the deformation joint at the sliding position of the water stop, prevents a water seepage channel from being produced, effectively anchors the water stop on the deformation joint, and keeps the waterproof capacity of the water stop.
The thickening agent of the invention is prepared by mixing hydroxypropyl methylcellulose and aluminum silicate, and simultaneously satisfies the thickening principle of inorganic thickening and cellulosic thickening, realizes complementation on the thickening principle, improves the viscosity of the anchoring agent, and simultaneously improves the shearing resistance and the tensile resistance of the anchoring agent, thereby playing a certain role in buffering the displacement between the water stop and the deformation joint.
The epoxy resin is matched with the nano calcium carbonate flexibilizer, the toughening effect is achieved by utilizing the strong rigidity of the nano particles, cracks are prevented from appearing in the anchoring agent, meanwhile, the mixture of light calcium powder and heavy calcium powder is used for matching the nano calcium carbonate, the curing speed is accelerated, the tolerance temperature and the whiteness of the anchoring agent are improved, and stronger viscosity can be obtained when the anchoring agent is mixed.
