Description
Technical field
The present invention relates to building material technical fields, are set more particularly to a kind of inorganic anchoring adhesive of rapid-hardening and mortar depositing construction
It is standby.
Background technology
In recent years, Building Trade in China develops rapidly, and extensive newly-built gradually march toward from the early days of foundation creates with transformation simultaneously
Weight period, transformation and the maintenance and reinforcement of existing structure or structure have become the hot spot of construction industry.Building and structure because
Use changes of function, force majeure（The natural calamities such as earthquake）, the reasons needs such as structure aging are transformed, reinforce and reinforcement
Newly-increased reinforcing bar is set to be worked together with original component that is reinforced by using bond-anchorage material Deng, rebar-planting anchorage technique, effectively
Solve the problems, such as these, along with cheap, constructing operation is simple and is most widely used.
Anchoring adhesive be to reinforce in building structure in using relatively broad, anchoring adhesive is generally divided into inorganic anchoring adhesive, You Jizhi
Muscle glue.Organic anchoring adhesive is bonded reinforcement material by the building structure that synthetic resin, packing material and chemical assistant form.It is organic
Anchoring adhesive has the advantages that it is notable, such as early strength height, mature etc., but organic anchoring adhesive also has what it was difficult to overcome to lack
Point, such as：（1）Differ too big with the elasticity modulus of concrete, the physics and chemistry such as wet-hot aging performance is poor, easy to aging, toxic, price is high
Matter defect；（2）Execution conditions require it is tight, cannot be too low or construct under high temperature very much.It is not easy to cure at low temperature；At high temperature
It is easy denaturation, Welding after first planting is difficult to realize at the construction field (site), increases the difficulty etc. of construction.（3）Use temperature range is narrow,
It cannot be in too low or construction and use too under high-temperature.Such as in low temperature（0 DEG C and following temperature）Under the conditions of use, be easy become
It is crisp；Such as in high temperature（100 DEG C and temperatures above）Under the conditions of be used for a long time, be easy denaturation, it may appear that the problem of mechanical properties decrease.
The inorganic type anchoring adhesive overwhelming majority is cement base inorganic anchoring adhesive, and this glue has high temperature resistant, not aging and concrete elastic mould
It measures the advantages that close, but its firm time is slow, adhesive bonds reinforcing bar and the bonding of base material concrete are strong under constraint drawing condition
Low, the poor non-deformability of Material ductility is low etc. is spent, and inorganic anchoring adhesive, using manually glue is added to bar planting hole, slip casting plumpness is not easy
Control, construction quality cannot be guaranteed, hinder development and the engineer application of inorganic type anchoring adhesive.
