Description
Technical field
The present invention relates to a kind of timber structure anchoring adhesive and preparation method thereof, and in particular to one kind can industrialized production, bonding
Functional, cheap timber structure anchoring adhesive and preparation method thereof.
Background technology
Anchorage inserted bar glue belongs to construction structure glue class, from material form upper anchorage inserted bar glue can be divided into organic type anchoring adhesive and
Inorganic type anchoring adhesive, common anchoring adhesive is organic type anchoring adhesive currently on the market.
Currently used organic type anchoring adhesive has two major classes, and one kind is epoxide resin type anchoring adhesive, and another kind is poly- amino
Formic acid fat high performance resin glue.Organic anchoring adhesive has the advantages of it is notable, such as early strength height, mature etc., but has
Machine anchoring adhesive also has the shortcomings that it is difficult to overcome, such as：
(1) physicochemical drawbacks such as wet-hot aging performance is poor, easy to aging, toxic, price is high；
(2) execution conditions requirement is tight, it is impossible to too low or construct under high temperature very much.It is not easy to cure at low temperature；In high temperature
Lower easily denaturation, is difficult to realize Welding after first planting, increases difficulty of construction etc. at the construction field (site).
(3) use temperature range is narrow, it is impossible in too low or construction and use too under high-temperature.Such as low temperature (0 DEG C and
Temperature below) under the conditions of use, easily become fragile；Such as long-time service under the conditions of high temperature (100 DEG C and temperatures above), easily becomes
Property, it may appear that the problem of mechanical properties decrease；
Thus, inorganic type anchorage inserted bar glue comes into being, and the inorganic type anchoring adhesive overwhelming majority currently on the market is cement
The inorganic anchoring adhesive of base, this glue are mainly made of silicates inorganic compound, have high temperature resistant, not aging and concrete
The advantages that elasticity modulus is close, is widely used in concrete structure bar planting, can be planted yet with base material timber in cement base inorganic
Significantly absorb water during muscle gelling is solid, influence cement base inorganic anchoring adhesive intensity, it is bad with wood substrates bonding, it is not suitable for straight
Connect and be used for timber structure bar planting.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of low cost, performance meets timber structure bar planting
Anchor desired structure glue and preparation method thereof.
The technical solution adopted by the present invention is：A kind of low cost timber structure anchoring adhesive, is mixed by two components of AB, its
In count in parts by weight, component A includes the raw material of following weight parts：Epoxy resin E51：100 parts, DBP toughener：5~10
Part, KH550 coupling agents, acetone diluent：5~10 parts；B component includes following weight parts raw material：50 curing agent of polyamide 6：50
Part, cement：100 parts, quartz sand：50 parts, silicon powder：100 parts, 10-20 parts of carbon fiber powder.
Preferably, the cement is commercially available 425 cement fine powder of Portland.
Preferably, the silicon powder is 500~2000 mesh powders.
Preferably, the quartz sand is 80~200 mesh powders.
Preferably, the carbon fiber powder is 400~800 mesh powders.
The preparation method of the present invention includes the following steps：
1) component A epoxy resin E51, DBP toughener, KH550 coupling agents, acetone diluent are stirred by said ratio
Uniformly, weighing and bagging is stand-by；
2) B component cement, silicon powder, quartz sand, carbon fiber powder are mixed with polyamide curing agent by said ratio,
Packed for standby use after 5~10min of stirrer for mixing；
3) component A and B component are uniformly mixed to slurry in 1: 1 ratio to obtain the final product.
Beneficial effect：The present invention is matched somebody with somebody after the advantage and disadvantage of existing anchoring adhesive product are fully used for reference by reasonable component formula
System, has prepared a kind of inexpensive timber structure bar planting glue, has had the following advantages that：
1) it is TCT21 in pesudotsuga taxifolia laminated wood strength grade, bar planting reinforcing bar is Φ 12, Φ 16,8.8 grades of threaded rods, bar plantings
Under depth L=15d, the constraint drawing condition that age is 7 days, the bonding of adhesive bonds reinforcing bar and base material pesudotsuga taxifolia laminated wood
Intensity is destroyed up to 8.4~11.0MPa, failure mode for reinforcement yielding or wood shear, and performance indicator meets timber structure bar planting
The requirement of glue；
2) there is strong cohesive force, volume stability, excellent durability, low cost, preferable resistance to elevated temperatures, it is right
Bonding strength is big, antidetonation, shock resistance and superior fatigue resistance.
