Description
Technical field
The present invention relates to building coating fields, apply more particularly to a kind of solvent-free high levelling durability epoxy resin anti-corrosion
Material and construction method.
Background technique
With the fast development of architectural engineering, concrete structure architectural engineering is more and more.As reservoir dam engineering,
The needs such as iron, tunnel, Urban Buried Pipeline Network, treatment tank engineering, sea port dock engineering, overhead road of city, underground parking garage are big
Measure waterproof, corrosion-inhibiting coating processing.For example esters of acrylic acid water-resistant coating is poor, durability is poor for common water paint；Application at present
More is epoxy coating, polyurethane coating.Since polyurethane coating and concrete substrate cementability are poor, epoxy
Resin becomes optimal selection.
Epoxy resin is a kind of high molecular material with linear structure, and per molecule on average contains 2 or 2 or more rings
Oxygroup is mainly synthesized by bisphenol-A and epoxychloropropane, and the hydroxyl and epoxy group contained in structure can be with acid anhydrides, phenolic aldehyde tree
Rouge, polyisocyanates, polyamide etc., which react, obtains the epoxy coating of different structure, different performance.In order to
Good application property, cementability and waterproof durability, usual epoxy resin are solvent based coating.Coating mostly contains volatilization at present
Organic matter (volatile organic compounds, VOC) causes sternly due to containing solvent and large-area construction to environment
The pollution of weight.Wherein, VOC refers under normal pressure, 50 DEG C -260 DEG C of boiling point of various organic compounds.It is most common have benzene, toluene,
Dimethylbenzene, styrene, trichloro ethylene, chloroform, trichloroethanes, diisocyanate (TDI), two isocyanide toluene esters etc..Work as residence
When VOC in room reaches a certain concentration, people can feel headache, Nausea and vomiting, out of strength etc. in the short time, will appear when serious
Twitch, stupor, and the brain, internal organ and nervous system of people can be hurt, cause the serious consequences such as failure of memory.
Nation-building resource-conserving and environment-friendly society at present, building coating is gradually to environmental-friendly and be conducive to
The development in healthy ecology building materials health direction.Solventless epoxy resin coating is not discharged into air during film-forming
Volatile organic matter, ingredient also have preferable working security finally all as film component, will not be because of solvent
It volatilizees and causes security risk, meet environmental requirement, while the drawbacks such as paint film contraction will not be caused because solvent volatilizees, by
The favor in market.As solventless epoxy resin coating was gradually developed in recent years, epoxy coating is to environment
Influence gradually decreases.At present there are mainly two types of the no-solvent type corrosion-resistant epoxy paints developed both at home and abroad: powdery paints and liquid without
Solvent epoxy coating.Powdery paints is made of a kind of with middle relative molecular mass or the solid epoxy of high relative molecular mass
Solid powder coating, liquid solvent-free epoxy coating is to use reactive reactive diluent as solvent, and solvent was solidifying
It will not volatilize in journey, but be cured and react with epoxy resin, eventually become a part in paint film.
If Chinese Patent Application No. 201710442599.8 discloses a kind of solvent free corrosion prevention erosion coating and preparation method thereof,
Its main constituents and weight proportion are as follows: wet process thin,tough silk female powder 5%-8%, reactive diluent 10%-15%, bentonite 8%-
10%, fatty amine curing agent 1.5%-5%, acrylic modified epoxy resin 35%-50%, glass flake 3.5%-5.5%, silicon
The coating of alkane coupling agent 3%-3.5%, thixotropic agent 0.5%-1% and defoaming agent 0.8%-1.5%, the invention have certain anti-corrosion
Property, it can effectively solve the problem that solvent volatility smell and pollution problem, however technical staff is using solventless epoxy resin coating
When, it is not easy working to ask since that there is matter is crisp, sticky, cementability is poor, smoothness is poor for solvent-free epoxy resin material itself
Topic further results in coating and is unable to satisfy the requirement under the harsh media environment such as corrosive liquid.Therefore, it is necessary to develop one
Kind no-solvent type epoxy anticorrosion coating, on the one hand can overcome epoxy coating to be difficult to the shortcomings that constructing, on the other hand exist
Still have adhesive force strong under corrosive liquid media environment, the excellent quality of acid and alkali resistance anticorrosive property, while can satisfy environmental protection and wanting
It asks.
Summary of the invention
For existing solventless epoxy resin coating matter is crisp, sticky, smoothness is poor, it is not easy to construct, anticorrosive property can
The problem of meeting the requirements, the invention proposes a kind of solvent-free high levelling durability anti-corrosive paint of epoxy resin, the present invention is proposed
The solvent-free high levelling durability anti-corrosive paint of epoxy resin of one kind and its construction method, are substantially improved waterproofness, the anti-corrosion of coating
Property and bonding fastness, be suitable for the media environments such as corrosive liquid.
To solve the above problems, the invention adopts the following technical scheme:
