Description
Technical field
The present invention relates to the structure glue that a kind of building trade is used, relate in particular to a kind of bridge dynamic structure glue that the complex fabric cloth reinforcement bridge is used of under the uninterrupted traffic state, pasting.
Background technology
Existing structure glue is reinforced in the use in bridge structure, finds that weak point is as follows:
1, in use there is following problem in makeup of the imports glue:
1.. curing cross-linking reaction is slow, and the construction time is long, gel does not take place in 2～3 days under cryogenic situation, and cure period, generally more than 10 days, initial adhesion strength was lower, had so not only influenced sticking effect but also had influenced on-site construction operations;
2.. the dynamic physical mechanical property is relatively poor after solidifying, and fragility is big, only is adapted at using under the static conditions.
3.. weather-proof relatively poor with ageing-resistant performance, use the later stage that xanthochromic trend is arranged.
2, in use there is following problem in homemade structure glue:
1.. viscosity is higher, and is poor to the wetting property of complex fabric cloth, influences bonding effect, also is unfavorable for constructing operation simultaneously.
2.. can not adjust working life, and the construction time of most of structure glue is shorter, especially in summer, very short time inner structure glue gelatin phenomenon just takes place, amount of preparation can not be excessive, is unfavorable for large-area construction, when temperature is low the construction time long again, influence the construction period;
3.. it is big equally also to exist fragility, and poor toughness only is adapted at static the use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bridge dynamic structure glue at the problems referred to above, and the present invention can be used to paste the complex fabric cloth reinforcement bridge under the uninterrupted traffic state.
Be achieved in that and it is characterized in that it is to be made of by following weight proportion two groups of raw materials of first, second in order to solve the problems of the technologies described above the present invention: wherein in the first component: 80～120 parts of Resins, epoxy; 1～2 part of rigid particles toughner-thermal silica; 0.5～2 part of antioxidant; UV light absorber-uv-90.5～1.5 part; 0.5～2 part of endurable active toughener-thiorubber; Reactive thinner-501 is 2～4 parts; Silane coupling agent-KH-560 is 0.5～2 part; 18～36 parts in solidifying agent in the component B wherein; 2.4～4.0 parts of promotor.
Preparation technology of the present invention is as follows:
One. the preparation of first component:
A. get rigid particles toughner-thermal silica by described weight proportion, thermal silica is placed in the agitator allocates, make it in the pasty state with 4～8 parts acetone; Add the silane coupling agent-KH-560 meet above-mentioned weight proportion again and stir and make the activation of rigid toughening particle, make colloid A;
B. add the reactive thinner-501 that meets described weight proportion after getting oxidation inhibitor and UV light absorber-uv-9 mixing by described weight proportion, solid particulate fully dissolves the formation solution B, preparation complex protection system;
C. get liquid-state epoxy resin by described weight proportion and endurable active toughener-thiorubber is put into another agitator simultaneously, heat, make agitator and inner material temperature thereof remain on 50～60 ℃, stir, make liquid C;
D. the above-mentioned colloid A for preparing and solution B are poured among the liquid C and stirred, the quiet object of back restir in agitator of putting becomes till the translucent liquid of oyster white, promptly gets the first component;
Two. the preparation of component B:
Get by described weight proportion that quiet putting after 35～55 minutes stirs gently in the container that the mixing of solidifying agent and promotor is placed on 65-85 ℃, be cooled to room temperature again, continue to stir 20～40 minutes, promptly get component B;
Three. above-mentioned first component for preparing and component B are mixed, promptly get bridge dynamic structure glue of the present invention.
Advantage of the present invention and effect are:
Bridge dynamic structure glue of the present invention is the structure glue of double-component cold curing agent, low viscosity, response type, it have good mechanical property, bond properties height, anti-dynamically, ageing-resistant performance is excellent, characteristics such as workability is good, and is nontoxic, pollution-free, its advantage is:
1, viscosity is suitable, and is good to the wetting property of complex fabric cloth, increases contact area, improves bonding effect.The curing cross-linking reaction gentleness, heat release is few, and temperature is lower, and it is unrestricted to join the glue amount.Be fit to extensive constructing operation.
2, by active composite toughening to Resins, epoxy, bridge dynamic structure glue not only can under static state be used, and be adapted at using under the vibrational state, its bond properties and physical and mechanical properties all there is not influence, thereby can be under the uninterrupted traffic situation reinforcement bridge, shock-resistant and vibrations excellent performance.
3, by composite epoxy resin solidifying system; Can arbitrarily be adjusted working life according to envrionment temperature, shorten the presetting period, adjust condensate content just, curing reaction course gradient is carried out, the fragility of having improved epoxy resin glue is solidified course.
4, by adjusting curing system, make the dynamic application specific architecture glue of bridge adapt to low-temperature curing, and the operation in wet environment, even carry out the bridge strengthening construction under water and also can use the present invention.
5, shrinking percentage is low, and the shrinking percentage of this glue is 0.2%～0.5%, is 1/2～1/5 of its their like product, and therefore conjugated fibre layer of cloth and the shear-stress between bridge member after the dynamic application specific architecture adhesive curing of bridge is little, not easy to crack; Good stability.
6, weathering resistance is good, has good uvioresistant and weather-proof and aging resistance, acidproof, alkaline-resisting and anti-various media (as oil, kerosene, alcohol, water etc.) excellent performance.Work-ing life is more than 50 years.
7, bridge dynamic structure glue makes the toxicological harmless, pollution-free in construction and use of this bridge dynamic structure glue with its free of contamination protection system.
