Description
Technical field
The invention belongs to anchor adhesive field, anchor member is chemically fixed on drilling by more particularly to one kind
Among high-performance epoxy anchor adhesive and preparation method and application.
Background technology
Anchor adhesive is generally made up of two components, is well mixed two components using preceding, then by hardware anchor
It is scheduled in base material, base material is typically the building being made up of concrete, the material of brick, natural stone etc..
Anchorage technology slowly grows up on the basis of expansion bolt.Expansion bolt can be produced around anchorage zone
Life stress very high, thus when by load action, during in particular by dynamic load function, expanding screw
Bolt is easy to loosen.In order to overcome the shortcoming of expansion bolt, early in nineteen fifty-nine, Germany begins one's study resin glue
Capsule is used to anchor mine anchor pole, and hereafter embedding re-bar technique is greatly developed, and gradually forms a kind of new antidetonation
Anchorage technology.And reinforced concrete structure China industry with civil buildings in occupy extremely important status and
Considerable quantity, with the development and the adjustment of the industrial structure of China's economic construction, generally requires to some
Engineering undergoes technological transformation or concrete structure is reinforced, therefore chemically-planted steel bar glue has obtained rapid hair
Open up and be widely applied.
The most frequently used polymer includes epoxy resin, unsaturated polyester resin, epoxide modified in chemical anchors solid glue
Acrylic resin, ethylene polyacrylates resin, polyurethane resin etc., the curing mechanism of every kind of polymer with
Curing system it is different and different, the characteristic of anchor adhesive is also not quite similar after solidification.Unsaturated polyester resin type,
Main chain is unsaturated polyester (UP), and reactant is styrene, because containing styrene reactant, its alkali resistant acts on energy
Power is low, and at architectural engineering scene, resin can at leisure absorb moisture, cause resin hydrolyzing, so as to interrupt tree
The strand of fat.Vinyl ester resin advantage is high chemical stability/durability, high temperature resistant, but it contains
Carcinogenic styrene, price is higher, and burning-point is low；Acrylic resin can typically accomplish 30min as anchor adhesive
Gel, reaches maximum intensity for 1~2 hour, but its anti-drawing strength is relatively low, it is impossible to meet anchoring resistance to plucking bar
Part.The anchor adhesive humidity resistance of polyurethane type resin is preferable, but the gel time that cold curing needs is more long,
It is 2~3 hours, and anti-drawing strength is poor.
Chinese invention patent CN103339082B discloses a kind of double component mortar and application thereof, describes
A kind of bi-component mortar that chemically anchor member is fixed among drilling, it has curable tree
Fat component and curing agent component, resin contain resin, filler, the promotion of at least one free redical polymerization
Agent, stabilizer and other optional common mortar compositions, described curing agent at least contain a kind of peroxidating
Thing.The hardening time of the bi-component sizing material of the invention is short, can be with rapid curing, but reaction diluent contains cause
Cancer substances styrene and its derivative, it is larger to environment and workmen's harm.
Chinese invention patent CN102190458B is disclosed and is suitable to building purpose, is especially suitable for chemical anchoring
Resin mortar, it comprises the resin Composition of available aliphatic amine and peroxide cure and comprising at least
The hardener component of a kind of peroxide and at least one amine, it is characterised in that the resin Composition includes energy
Carry out the compound of radical polymerization, can with amine react compound, selected from Cu, Mn and Fe compound
Transistion metal compound, at least one inhibitor adjust gel time and with least two reactivity
The bridge joint compound of functional group.The intensity of the anchor adhesive of the invention is big, stability is high, but the receipts of solidfied material
Shrinkage is larger, poor heat resistance, and temperature is too high to increase creep, deformation, causes building steel-bar-planting unstability.
Chinese disclosure CN101619188A discloses a kind of underwater high-strength epoxy anchor adhesive and its preparation
Method.The anchor adhesive is made up of the component of A, B two, component A by epoxy resin, diluent, toughener,
Coupling agent, thixotropic agent, filler, defoamer composition, B component are made up of QS-H205 curing agent.Use
When press 5~8:1 mixed preparing obtains final product underwater epoxy anchor adhesive.The performance test results show that compression strength is 75.1
MPa, tensile strength is 11.3MPa, and bending strength is 59.4MPa, and pull-out test result is
290.6~295.5kN.The water-tolerant of anchor adhesive of the invention, but insufficient strength is big, resistance to elevated temperatures
It is bad.
Chinese disclosure CN1608092A discloses a kind of patent of invention adhesive composition, described
Adhesive can be used in concrete or masonry or to fixing material, including epoxide on concrete or masonry
And curing agent, the curing agent includes at least one aliphatic amine and at least one tertiary amine.The adhesive of this invention
Hardening time it is short, but fatty amine excitant is larger, and the solidfied material for obtaining is firmly crisp, and anti-drawing strength is small, and
And pollution environment.
Chinese invention patent CN103320074B disclose under a kind of low temperature environment rapid curing anchor adhesive and
Its preparation method.The anchor adhesive is made up of A, B, and component A raw material includes that vinylite, vinyl are dilute
Release agent, peroxide initiator, stabilizer, acid anhydrides, filler, B component raw material include vinylite,
Vinyl diluent, accelerator, stabilizer, alkaline earth oxide, filler.Ring of the invention in low temperature
Can solidify under border and reach certain intensity, can be used in winter, but diluent is carcinogen styrene
And its derivative, and not acid-alkali-corrosive-resisting, for a long time facile hydrolysis in wet condition.In addition, the solidfied material
Also non-refractory, at high temperature can creep so that the security reduction of building.
Invention advantage and disadvantage described above are obvious, in order to solve above-mentioned mentioned non-refractory, not humidity
Property, anti acid alkali performance is poor, intensity is poor, pollution environment, the shortcomings of fatty amines corrosivity is strong.The present invention is logical
Cross test of many times and obtained that a kind of acid and alkali-resistance, high temperature resistant, environment friendly and pollution-free, mechanical strength be high, combination property
Epoxy anchor adhesive high.
