Band, concrete structure many places are under saline-alkali environment, wherein the solution containing chemical substances such as chloride ion, sulfate radical, hydroxyls is long
Time impregnates concrete, destroys concrete structure, phenomena such as loosely organized, peeling, fall off occurs, and then to inside
Reinforcing bar is corroded, and finally will affect the safety of main structure, so carrying out durability protection to concrete structure will protect
Barrier China's capital construction is able to achieve the important means of national project of vital and lasting importance target.
Water-proof and anti-corrosive material traditional at present mainly has the materials such as polyurethane, polyureas, these materials are to be attached to coagulation
Native surface forms one layer of waterproof layer, good waterproof action can be played in concrete topping, but impermeable into inside concrete
Carry out deeper protection, it is easy to because the effects of external impacts, stress, occurs falling off, destroys and lose protection effect,
Concrete structure will be exposed to environment again and suffer erosion.Therefore, there is excellent chemical corrosion, high-durability and very
The water proof anti-corrosive paint of good physical property will be future market trend.
There are the groups such as phenyl ring, ehter bond, hydroxyl, epoxy group, it is very good that phenyl ring assigns epoxy resin in epoxy molecule
Physical property and heat resistance, ehter bond assigns its good chemical resistance, and hydroxyl has the interfaces such as epoxy and concrete, reinforcing bar
Good caking property, epoxy group allow it to have reactivity well, select suitable curing agent can allow material at normal temperature
Solidification can be reacted, induration has extraordinary chemistry, physical property, and one epoxy group of reaction will release one
A hydroxyl promotes the cohesive force of epoxy resin further.The excellent chemical corrosion resistance of epoxy resin, good cementability,
And very high mechanical strength, it is highly suitable for the works such as water proof anti-corrosive paint, the epoxide terrace paint in architectural engineering, adhesive
Industry field.
Such as China Patent Publication No.: CN102504670A, denomination of invention: permeable epoxy resin waterproof coating for concrete,
A kind of concrete permeability epoxy resin waterproof coating composition is provided in this application；China Patent Publication No.:
CN102433057A, denomination of invention: a kind of waterproof reinforced coating of bi-component high osmosis epoxy resin and preparation method and application.Two
Patent component A resin based on epoxy resin and bisphenol F epoxy resin, using furfural, acetone and reactive diluent, many institutes
Known, acetone is inflammable and explosive, easy drugs class control raw material processed, produces and is easy to happen the danger such as burning, explosion when constructing,
It evaporate into after the acetone in air is inhaled into and harm is generated to human body, it is less desirable in production and use aspect.B component is adopted
Solidified with polyamines, these curing agent itself and poor toughness after epoxy resin cure, only adjusts product by addition type toughener
Flexibility, phenomena such as that the induration after reaction is still more crisp, and there are durabilities is poor, brittleness rebound, waterproof layer is caused to occur
It destroys.
Therefore, it is necessary to which it is excellent to develop a kind of low viscosity, high-durability and physics, chemical property, it is anti-to have excellent waterproof
