20 DEG C are used, and keep function normal;Allow for resisting chemical attack;Necessary high temperature resistant, wet environment, resistance to greasy dirt,
Resistance to frequently high temperature difference etc..
Concrete floor such as diamond dust abrasion-proof terrace, has excellent mechanical performance, it is easy to construct, but structural porous, and material
Material is highly polar so that concrete body easily absorbs foreign matter, such as oiliness compound, even corrosive organic acid.Concrete
Main component silicate can not sufficiently resist the corrosion of chemicals.If be not modified by main in structure, draw
Enter a large amount of new functionalized chemical groups, acrylic resin generally only applies the place such as high resiliency acrylic carried in slight industry
Court etc..For example, US5543232 discloses a kind of acrylic resin modified varnish of photocuring, with good elasticity, it is adaptable to
General place.Epoxy resin is the matrix resin being most widely used, with outstanding anticorrosion and mechanical mechanics property.Epoxy
Contain substantial amounts of phenyl ring in resin structure, coating is hard;Alkyl and ehter bond are also there are, the adhesive force to concrete substrate is excellent
Good, alkali resistance is excellent, is resistant to most of organic solvent.Epoxy resin is always all as in anticorrosive coating and heavy corrosion environment
First-selected corrosion protection base-material.But epoxy resin curing reaction at low temperature is slow, and construction effect and coating performance are undesirable.For example,
US8133941 discloses a kind of aqueous double-component epoxy-resin systems, can adjust hardening time.
Because the performance of polyurethane is very prominent and superior, meet the application feature under extreme condition, thus be adapted to as
Floor material in above-mentioned environment.Polyurethane resin is typical elastomeric material, and the curing reaction of feature has polyurethane
