The invention relates to a composite shield segment abutted seam water stop function resetting method, and relates to the technical field of shield tunnel segment abutted seam water stop function repairing, and the method comprises the following steps: firstly, determining whether the water stop function of a water stop strip is damaged and needs to be replaced, and then forming a first grouting hole and a second grouting hole with different parameters in the segment surface along the abutted seam length direction; polyurea grouting liquid and epoxy resin grouting liquid are injected respectively to form a first waterproof layer and a second waterproof layer, and then epoxy plaster and polyurea sealant are smeared in sequence to form a third waterproof layer and a fourth waterproof layer; a hole in the back of the lining can be positioned and grouted; and giving out calculation formulas of the punching angle, spacing and quantity of each grouting hole, and limiting components, proportions, construction parameters and the like of related materials. The method has the effect that the waterproof performance of the abutted seam can be effectively recovered.

The invention provides epoxy putty for an oil storage container, which is formed by mixing a component A and a component B. The component A is prepared from the following components in parts by mass: 15-25 parts of novolac epoxy resin, 3-6 parts of a resin modifier, 0.2-0.4 part of a dispersant, 0.7-1 part of bentonite, 0.25-0.35 part of a defoaming agent, 2-4 parts of a reactive diluent, 60-75 parts of quartz powder and 4-6 parts of titanium dioxide; the component B comprises the following components in parts by weight: 5-8 parts of a curing agent, 0.2-0.3 part of a drier, 20-30 parts of quartz powder and 0.5-1 part of a thixotropic agent; the mixing mass ratio of the component A to the component B is (2.6: 1)-(3.6: 1). The epoxy putty prepared by the invention is high in drying speed, has excellent adhesive ability and permeability resistance to small molecules such as oil gas, and can reduce the risk of leakage of an oil storage container.

The utility model relates to the technical field of flat floor technology discloses a multilayer composite wear -resisting type epoxy flat floor, including base layer, the top fixedly connected with high permeability epoxy primer for reinforcing of base layer, the top fixedly connected with wear -resisting core layer for compression resistance of high permeability epoxy primer, the multilayer composite wear -resisting type epoxy flat floor is set up cooperation through base layer, high permeability epoxy primer, wear -resisting core layer and epoxy putty closed layer, and the setting of base layer provides the basis for coating adhesion, through the setting of high permeability epoxy primer, play the role of permeation reinforcement base surface, close matrix capillary hole to promote the adhesion, can make the reinforcement degree of base surface higher, through the setting of wear -resisting core layer, play the role of compression resistance, impact resistance and heavy load resistance, can bear higher mechanical wear, through the setting of epoxy putty closed layer, play the role of closed mortar layer pore, provide smooth delicate base surface to enhance the adhesion of finish.

The application discloses an acrylic polyurethane / silane composite protective coating and a preparation method and application thereof in concrete surface protection, and belongs to the technical field of building coatings. The protective coating is used on the concrete surface and comprises, from bottom to top, an epoxy putty layer, a modified silane impregnated intermediate layer and a modified acrylic polyurethane top coating layer. The raw material components of the modified silane impregnated intermediate layer include, in terms of mass parts, 35-45 parts of a silane impregnating agent, 0-5 parts of nano-silicon dioxide, 0-5 parts of silica sol, 0-5 parts of ethyl silicate and 0-5 parts of polyurea. The sum of the amounts of the nano-silicon dioxide, the silica sol, the ethyl silicate and the polyurea is greater than 0. The application combines the material properties of the acrylic polyurethane, the silane impregnating agent and the nano-silicon dioxide, and plays the component synergistic coupling effect, so that the protective surface coating with the functions of damage repair and reinforcement, good durability, hydrophobic self-cleaning and the like is obtained.
