The invention relates to a solvent-free epoxy anti-permeability barrier coating.The solvent-free epoxy anti-permeability barrier coating comprises components A and components B.The components A comprise, by weight, 80-100 parts of epoxy resin, 5-15 parts of flexibility improving resin, 5-15 parts of diluents, 0-1 part of defoaming agents and 0.1-0.5 part of leveling agents; the components B comprise, by weight, 80-100 parts of modified amine curing agents and 0-5 parts of silane coupling agents.The solvent-free epoxy anti-permeability barrier coating is mainly used for waterproof treatment on cement base planes and has the advantages of low viscosity, high elongation, adhesion and toughness and the like.
Description
Technical field
The present invention relates to adhesive industry, particularly relate to a kind of no-solvent type impervious seal coat of ring oxygen and its preparation method.
Background technology
In the fast development building especially road and bridge, high ferro industry in industry, higher requirement is proposed in base face, due to the easy water-absorbent of cement, often due to moisture in cement matrix and cause the reduction in the work-ing life to whole road surface. In order to prevent the corrosion problem that moisture in cement causes and then the work-ing life improving overall road surface, bridge floor, it is imperative that road surface, bridge floor carry out the WATER REPELLENT in cement based face. The water-proof materials such as current cement based face water-proof system many employings modified bituminous pitch coiled material, polyurea system. The paving of modified bituminous pitch coiled material is covered to be needed to be processed in base face, simultaneously also not high with the adhesiveproperties of cement; If cement based face or matrix exist water molecules, can occur with polyurea system to react the risk simultaneously having small molecules release and produce bubble, the film-forming properties on surface and the work-ing life of overall road surface and bridge floor can be affected. Especially now to the raising of environmental requirement, a lot of occasion does not re-use solvent type adhesive, the no-solvent type Epoxy waterproof system that the present invention relates to has low viscosity, snappiness, the cementability high with cement based face, easy to operate, there will be no and the risk problem of water molecule reaction in cement, and also have relatively excellent adhesion property with cement based face when certain wet surface construction.
CN103849296A discloses a kind of elastic epoxy resin waterproof paint and its preparation method, wherein adopt epoxy resin and the conventional modified amine curing agent main raw material as A, B component, and add the flexibility that softening agent improves material, but the elasticity of this waterproof paint, toughness and cohesiveness still have much room for improvement.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of no-solvent type impervious seal coat of ring oxygen, this coating has the features such as low viscosity, snappiness, high tenacity, high adhesion and ease for operation, it is possible to be applicable to the WATER REPELLENT in cement based face.
In order to realize the object of the present invention, it is proposed to following technical scheme:
A kind of no-solvent type impervious seal coat of ring oxygen, with weight parts, component A consists of:
B component consists of:
Modified amine curing agent 80～100 parts
Silane coupling agent 0～5 part;
Component A mixes with the ratio of weight ratio 10:1 to 1:10 with B component, it is preferable that weight ratio 1:1.
Described modified amine curing agent is prepared from by polyetheramine, N-aminoethyl piperazine, amine curing agent, phenol and paracril. It is preferably multi-ethylene polyamines, it is more preferable to be triethylene tetramine, tetraethylene pentamine, diethylenetriamine.
Described amine curing agent is phenolic aldehyde amine curing agent, one or more in polyamide curing agent, fat cyclammonium solidifying agent and fatty amine curing agent;
Described phenol is alkylphenol, it is preferable to nonyl phenol.
Described polyetheramine, N-aminoethyl piperazine, amine curing agent, phenol and paracril proportioning by weight is 8-10:5-7:0.5-1.5:8-10:3-7.
Described epoxy resin is one or more mixtures in bisphenol A epoxide resin, bisphenol F epoxy resin, novolac epoxy, hydrogenated bisphenol A epoxy resin;
The soft resin of described increasing is longer chain polyethylene glycols glycidyl ether liquid resin, long-chain polypropylene glycol glycidyl ether liquid resin and/or long-chain polytetramethylene glycol glycidyl ether liquid resin;
Described thinner is response type epoxide diluent, it is preferable to the mixture of one or more in alkyl glycidyl ether, butylglycidyl ether, phenyl glycidyl ether, benzyl glycidyl ether, ethylene glycol diglycidylether, propylene glycol diglycidylether, butyleneglycol glycidyl ether.
Described defoamer is the broken bubble polymers soln not containing organosilicon.
Described flow agent is polyether-modified polydimethylsiloxane interpolymer.
The preparation method of described modified amine curing agent is: join in flask by polyetheramine, N-aminoethyl piperazine, amine curing agent, phenol, and logical nitrogen protection, at 40 DEG C of insulated and stirred 2～3h; raised temperature to 60 DEG C again; add paracril, insulated and stirred 3-5h, it is cooled to room temperature for subsequent use.
In described B component, silane coupling agent is KH-550 coupling agent.
Present invention also offers the preparation method of the above-mentioned no-solvent type impervious seal coat of ring oxygen, comprise the steps:
1) modified amine curing agent is prepared:
In proportion polyetheramine, N-aminoethyl piperazine, amine curing agent, phenol are joined in flask, logical nitrogen protection, at 40 DEG C of insulated and stirred 2～3h, then raised temperature to 60 DEG C, add paracril, insulated and stirred 3-5h, it is cooled to room temperature for subsequent use; Wherein polyetheramine, N-aminoethyl piperazine, amine curing agent, phenol and paracril proportioning by weight is 8-10:5-7:0.5-1.5:8-10:3-7;
2) component A is prepared:
(1) described epoxy resin, increase soft resin preheating 6-8h at 60 DEG C of temperature in advance;
