Description
Technical field
The present invention relates to a kind of timber structure anchoring adhesives and preparation method thereof, and in particular to one kind can industrialized production, bonding
It is functional, be resistant to 150 DEG C of high temperature, cheap timber structure organo-mineral complexing anchorage inserted bar glue 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；
Inorganic type anchorage inserted bar glue comes into being as a result, 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
It significantly absorbs water during muscle gelling is solid, influences cement base inorganic anchoring adhesive intensity, it is bad with wood substrates bonding, it is not suitable for straight
It connects for timber structure bar planting.
The content of the invention
It, can be long-term under 150 DEG C of high temperature it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of low cost
It uses, performance meets structure glue of timber structure bar planting requirement and preparation method thereof.
The technical solution adopted by the present invention is：A kind of high temperature resistant organo-mineral complexing timber structure anchoring adhesive, by two components of AB
It is mixed, wherein counting in parts by weight, component A includes the raw material of following weight parts：Epoxy resin E51：100 parts, aqueous ring

55 curing agent：50 parts, cement：70~100 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, aqueous epoxy resins, DBP toughener, KH550 coupling agents are stirred by said ratio
It mixes uniformly, weighing and bagging is for use；
2) B component cement, silicon powder, quartz sand, carbon fiber powder and modified amine JH5-55 curing agent are mixed by said ratio
It closes, the 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.
Advantageous 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 high temperature resistant organo-mineral complexing timber structure anchoring adhesive, has had the following advantages that：
1) it is TCT21 in pesudotsuga taxifolia strength grade, bar planting reinforcing bar is Φ 12,16,8.8 grades of threaded rods of Φ, bar planting depth L
Under=15d, the constraint drawing condition that age is 7 days, the adhesion strength of adhesive bonds reinforcing bar and base material pesudotsuga taxifolia laminated wood can
Up to 8.4~11.0MPa, failure mode destroys for reinforcement yielding or wood shear, and performance indicator meets wanting for timber structure anchoring adhesive
It asks；
2) there is cohesive force strong, volume stability, excellent durability, low cost, high temperature resistant (long-time service at 150 DEG C) etc.
Feature, antidetonation, shock resistance and superior fatigue resistance big to bonding strength.
Specific embodiment
