Description
Technical field
The present invention relates to field of mortar, specially a kind of wet spraying polymer mortar.
Background technology
With the fast development of Chinese infrastructure construction, infrastructure project service life is put forward higher requirement.Especially
It is bridge, high-speed railway, special railway line, highway etc., design, construction, performance etc. is required higher.But it is many built
Xoncrete structure, because design is comprehensive, not in place, operation maintenance imperfection of constructing, and nature can not resist factor, such as ooze
Leakage, ice damage, corrosion etc., cause structure destruction serious, and such as crack, surface concrete peeling, the exposed disease of reinforcing bar occur in structures
The destruction such as evil, road surface, bridge pier, dykes and dams, causes these structure durabilities drastically to decline, therefore to the dimension of existing concrete structure
Repair, reinforce the particular importance that seems.Mortar is a kind of material being widely used in repairing and reinforcing engineering, currently used for concrete
The mending mortar of structure mainly has following three major types：(1) conventional cement mortar be it is the most frequently used be also the mending mortar for using earliest,
It includes the composition such as common portland cement, quartz sand, thickener, defoamer, water reducer.This kind of mortar is cheap, skill
Art is ripe, and later strength is higher；(2) epoxy resin mortar, with epoxy resin as Binder Materials, with quartz sand, thickener, froth breaking
Agent etc..Such mortar adhesive property is good, and intensity is big；(3) high molecular polymer cement mortar, typically from type of latex type polymer or
The emulsion powder-modified cement mortar of person's recyclability, can obviously improve the rupture strength of conventional cement mortar, and adhesive strength is impervious
Property, corrosion resistance.In order to improve the crack resistance of mortar, chopped strand is also usually added, it is the most frequently used for polypropylene fibre.With
Construction material application variation, special typeization, the demand of high performance, traditional cement mortar has been difficult to meet.Embody
, although common cement mortar compression strength is high, its poor toughness, easily contraction, cracking, and adhesive property is bad, and it is early
The shortcomings of phase low intensity.Epoxy resin mortar is a larger breakthrough, and cement is substituted as Binder Materials with epoxy resin, hence it is evident that
Improve the cementability of mortar, toughness, resistance to water etc., but its situ configuration is loaded down with trivial details, high cost, easily occur after repairing it is aging,
Come off.At present the domestic universal cost of high molecular polymer cement mortar is partially expensive, and early strength development is slow, later strength retraction,
Easily occur shrinking and ftractureing after repairing, in consideration of it, a kind of it is proposed that wet spraying polymer mortar.
