Abstract
The invention discloses a solvent-free double-component epoxy moisture-proof film and belongs to the field of concrete interface processing. The solvent-free double-component epoxy moisture-proof film comprises the following components in part by weight: 1) a component A which is 100parts of modified epoxy resin; and 2) a component B, which consists of 15 to 25 parts of curing agent, 1 to 5 parts of curing accelerator and 1 to 5 parts of functional assistant. The mass ratio of the component A to the component B is 1:2.5. When the solvent-free double-component epoxy moisture-proof film disclosed by the invention is used as a cement-based self-leveling interface agent, the rise of bottom moisture can be prevented effectively; and the solvent-free double-component epoxy moisture-proof film has high bonding strength and is environment-friendly without environment-polluting materials such as formaldehyde.
Description
Technical field
The invention belongs to the concrete interface process field, be specifically related to a kind of solvent-free bi-component epoxy damp-proof membranes that is used for cement-based self-leveling.
Background technology
In the construction of cement-based self-leveling, interfacial agents is extremely important.And on some ground, because the factor of each side such as environment, basal plane is very moist, the basic unit of perhaps not doing waterproof layer.Because the rising of basic moisture can reduce the bonding of cement-based self-leveling and basic unit.The rising of moisture simultaneously also can and indoorly cause very big influence to whole ground, and as paving PVC floor, ground can cause that the PVC floor plays drum.In the prior art, to the processing of wet base, be technological difficulties in the cement-based self-leveling construction, almost be not reported.
Summary of the invention
The present invention provides a kind of solvent-free two component epoxy damp-proof membranes for solving the problem of the wet ground that runs into when current cement-based self-leveling is constructed, and is used for the interfacial agents of cement-based self-leveling, makes it effectively stop the rising of bottom moisture.
Solvent-free two component epoxy damp-proof membranes provided by the invention in parts by weight, comprises following component:
A component: modified epoxy 100;
The B component: solidifying agent 15-25,
Curing catalyst 1-5,
Functional aid 1-5;
Wherein, the mass ratio of A, B component is 1: 2.5.
Described modified epoxy is the polyurethane modified epoxy resin of ultra-low viscosity, and viscosity is 100-800mpas.
Described solidifying agent is the polyether monoamine solidifying agent.
Described curing catalyst is one or more in tertiary amine, methyldiethanolamine, amino-phenol, the Whitfield's ointment.
Described functional aid comprises defoamer, flow agent and wetting agent, wherein said defoamer is polyethers defoamer (for example BYK-606N), described flow agent, wetting agent are modification silicon polymer based on multiple copolymer (for example flow agent K-729, wetting agent H-140); The mass ratio of defoamer, flow agent, wetting agent is 1-3: 2: 1.5.
Above-mentioned B component is fully disperseed in proportion, and according to A: B=1: the mixed of 2.5 (mass ratioes) promptly obtains solvent-free bi-component epoxy damp-proof membranes of the present invention.
The present invention makes the epoxy damp-proof membranes have better penetrating power by reducing the viscosity of Resins, epoxy, makes it can be good at sealing bottom cement hole, reaches the purpose that sealing bottom steam rises.Accelerate curing speed by adding curing catalyst simultaneously, satisfy construction requirement.
Solvent-free bi-component epoxy damp-proof membranes of the present invention can stop effectively that as the interfacial agents of cement-based self-leveling the bottom moisture rises.And harm surrounding materials such as its cohesive force is strong, environmental protection does not contain formaldehyde.
