Description
Technical Field
The invention belongs to the technical field of concrete waterproofing, and particularly relates to a concrete surface waterproof treating agent and a treating method.
Background
At present, most of concrete surface waterproof treatment uses a method for adhering a waterproof layer on the surface of a concrete base layer, the conventional base layer treatment generally comprises the steps of removing dust, floating soil and sand grains of a leveling layer, and then coating cold base oil to form a layer of colloid film between the surface of the base layer and a waterproof coiled material so as to improve the bonding property, wherein the cold base oil is building petroleum asphalt or tar asphalt. However, the colloidal film formed by petroleum asphalt or tar asphalt still has certain defects in the aspects of hardness, penetration binding force with the concrete surface and binding force with the waterproof coiled material, so that the waterproof layer has short service life and poor waterproof effect.
Patent CN 105672497 a discloses a concrete substrate surface waterproofing treatment method, which comprises the following steps: 1) the method comprises the following steps of arranging a waterproof mortar bonding layer on the surface of a concrete substrate by using waterproof mortar, and arranging a waterproof base layer treating agent layer (asphalt waterproof base layer treating agent) on the waterproof mortar bonding layer, wherein the waterproof mortar comprises water and cement, and the content of water in the waterproof mortar is 30-40 wt%; a good base layer with anti-permeability properties is obtained. 2) And arranging a waterproof layer (which is a waterproof coiled material or a waterproof coating layer) on the waterproof base layer treating agent layer to obtain the anti-permeation layer of the concrete base layer. This layer is the primary waterproof layer. Although the technology of the patent enhances the binding force between the surface of the concrete substrate and the waterproof substrate treating agent layer and improves the waterproof property by arranging the waterproof mortar adhesive layer, the technology still does not solve the problem that the binding force between the asphalt waterproof substrate treating agent and the waterproof roll or the waterproof coating layer is not enough. And the arrangement of multiple functional layers has higher construction requirements, and the quality stability is difficult to control.
Patent CN107686281A discloses a waterproof concrete surface treating agent, which comprises, by weight, 25-88 parts of nano calcium carbonate, 5-20 parts of benzyl silicone oil, 5-15 parts of carboxymethyl methyl cellulose, 30-60 parts of polypropylene, 10-20 parts of polyvinyl alcohol, 5-15 parts of glass powder, 4-9 parts of polyvinyl acetate emulsion powder, 20-60 parts of fine sand, 3-8 parts of an antifoaming agent, 15-45 parts of collagen fiber, 10-30 parts of polyamide acid, 10-25 parts of graphite powder and 15-25 parts of paraffin. The surface treating agent is coated on the surface of the fair-faced concrete, so that holes on the surface layer of the concrete can be effectively filled, the surface layer of the concrete is sealed and solidified, the corrosion of chemical substances in the environment is prevented, and the service life of the fair-faced concrete is prolonged. The waterproof coating achieves good impermeability and waterproofness mainly through combination of various functional components, the components are complex, the cost is high, and the problem of seepage binding force between the waterproof coating and the surface of a concrete substrate is not solved.
Patent CN 108440018A discloses a method for protecting concrete surface, comprising the following steps: (1) dispersing graphene oxide in water, and fully and uniformly dispersing to obtain a graphene oxide aqueous dispersion liquid; (2) coating the graphene oxide aqueous dispersion liquid on the surface of concrete in a soaking or coating mode until the thickness of the graphene oxide layer on the surface of the concrete is more than or equal to 10 microns; (3) and (3) carrying out reduction treatment on the concrete coated with the graphene oxide layer on the surface, and removing most hydrophilic groups in the graphene oxide to obtain the hydrophobic graphene surface protective layer. The treatment method greatly reduces the water absorption of the concrete and greatly improves the resistance of the concrete surface to erosion media. However, the application of graphene oxide to concrete and the reduction treatment of concrete with graphene oxide layers on the surfaces thereof are expensive and difficult to be applied industrially.
