Abstract
The present invention is aiming at preparing an adhesive for dynamic load members and structures, particularly an adhesive which is suitable for the adhesion of various reinforced concrete and steel structures. The present invention has the key points that three modifiers of 20 to 30 parts of polyamide, 5 to 12 parts of polysulfide rubber and 4 to 7 parts of dibutyl phthalate are added into 100 parts of epoxy resin; furthermore, fillers, an antiaging agent and an ultraviolet absorbent are then added, and finally, a solidifying agent is added for stirring for 10 minutes at normal temperature and solidifying for 48 hours. The adhesive has the advantages of good elasticity, tenacity, flexing resistance and antifatigue performance, strong antiaging property and low cost, and can be used as an adhesive for adhering various large-sized reinforced concrete crane beams.
Description
The present invention relates to composition epoxy resin, be used for the tackiness agent of moving load member and structures, particularly be suitable for the bonding tackiness agent of various Steel Concrete and steel construction.
At present, the kind of tackiness agent is a lot of in the prior art, as quick-setting thermally stable adhesive, waterproof concrete adhesive or the like, is mostly to be used for bonding same material or inorganic materials, also is useful on tackiness agent bonding under the static load conditions.But industrial often the needs bonds together the member of unlike material, and as reinforced concrete member and the bonding tackiness agent of structural part of steel plate, the tackiness agent that especially bears member under the moving load working conditions and structures is still unresolved so far.As CN85102366 waterproof concrete adhesive composition, though solved various light construction accessories and concrete bonding problem, with regard to its use range, can't be applicable to moving load member and structures bonding.
It is good to the objective of the invention is to prepare a kind of elasticity, toughness, flexing resistance, anti-fatigue performance, and ageing resistance is strong, and cost is low, is applicable to the tackiness agent of metal and concrete bonding under member or the structures moving load condition.
Main points of the present invention are to add properties-correcting agent, filler, protective agent, UV light absorber and solidifying agent in Resins, epoxy.
Wherein: properties-correcting agent is made up of (add-on in 100 parts of Resins, epoxy) polymeric amide 20-30 part, thiorubber 5-12 part or end carboxylic paracril 20-25 part, phthalic acid two butyric acid 4-7 parts.Thiorubber has multiple functions such as plasticising, curing, is a kind of indispensable properties-correcting agent, thiorubber and Resins, epoxy reaction, and the segmented copolymer of the two plays plastification, and makes this tackiness agent have elasticity, toughness.
In view of this tackiness agent be mainly used in the moving loading structure concrete and steel plate bonding, for making its elastic modulus E, coefficient of expansion α and shrink between steel plate and concrete, the present invention has also added the mixture of 50 parts of ordinary Portland cements and 50-100 part iron powder as filler in tackiness agent.
Protective agent of the present invention is the N-Phenyl beta naphthylamine, and UV light absorber is 2-hydroxyl-4-methoxyl group-benzophenone, and both add-ons are 0.5-1.0 part.Its purpose is to improve the anti ageing property of tackiness agent.
The present invention has also added 4-11 part quadrol or 12-16 part beta-hydroxyethyl quadrol as solidifying agent in this tackiness agent, under 15 ℃ of-25 ℃ of temperature, solidified 40-48 hour.
Compound method of the present invention is in Resins, epoxy, at first add properties-correcting agent, add successively: polymeric amide (production of chemical plant, Yan'an, Tianjin), thiorubber (model that chemical plant, Jinxi institute produces is that LP-3 type molecular weight is about 3000) or end carboxylic paracril (production of Lanzhou chemical industrial company), dibutyl phthalate, mix, the filler that to mix in advance then: its composition amount is 40-60 part ordinary Portland cement, preferably adopt the 425# ordinary Portland cement, 50 parts of optimal addns; Iron powder 50-100 part, 80 parts of optimal addns, with protective agent N-Phenyl beta naphthylamine 0.5-1.0 part, UV light absorber 2-hydroxyl-4-methoxyl group-benzophenone 0.5-1.0 part is dropped in the preparation container together, be stirred to glue at normal temperatures, add curing agent ethylene diamine 4-11 part or beta-hydroxyethyl quadrol 12-16 part at last slowly, stir more than 10 minutes, solidifying controlled temperature is 15 ℃-25 ℃, 40-48 hour set time.
With embodiment the present invention is illustrated below:
100 parts of Resins, epoxy
Thiorubber 5-12 part
Polymeric amide 20-30 part
Dibutyl phthalate 4-7 part
50 parts of ordinary Portland cements
Iron powder (4900 holes/centimetre
2Tail over 25%) 50-100 part
Protective agent (N-Phenyl beta naphthylamine) 0.5-1.0 part
UV light absorber (2-hydroxyl-4-methoxyl group-benzophenone) 0.5-1.0 part
Solidifying agent: quadrol (or beta-hydroxyethyl quadrol) 4-11 part
Resins, epoxy is preferably got 100 parts of E42-51 Resins, epoxy when this tackiness agent of preparation, as when reinforcing above heavy duty crane beam of 75t and prestressed reinforced concrete bridge beam, preferably adopt nbr carboxyl terminal 22, and the nitrile content about 30% of end carboxylic paracril, molecular weight 3000, its consumption is the 20%-25% of Resins, epoxy, with the 650# polymeric amide, dibutyl phthalate is mixed thoroughly together as properties-correcting agent, the filler that to mix thoroughly in advance then: by the most handy 425# silicate cement of silicate cement, iron powder is formed, and protective agent, UV light absorber adds in the preparation container together, be stirred to glue, should stir along a direction behind the adding solidifying agent, in order to avoid produce bubble, during stirring such as hand mixing more than 10 minutes, mechanical stirring is more than 5 minutes, and be 40-48 hour set time, and tackiness agent promptly is mixed with.
By the moving loading structure adhesive that the present invention prepared, when being used for moving load working conditions lower steel plate and Steel Concrete bonding, bonding back shearing resistance is average 〉=12.6MPa, average pull strength is 〉=18MPa, mean compressive strength 〉=70.6MPa, the model of GL1.18-5 and this code name of GL1.18-6(all being represented reinforced beam) static loading test of beam, its supporting capacity improves 1-3 doubly, amount of deflection reduces 36%-72%, metal, steel and steel bond are after 400 hours weathering tests, its adhesive shear strength improves 36% approximately, the GL1.18-5 affixing steel plate is qualified fully through 4,000,000 fatigue tests, this moving loading structure adhesive, suitable large-scale heavy-duty Steel Concrete crane girder, prestressed reinforced concrete bridge beam and similar moving load member and construct part and reinforce more are applicable to quiet lotus structural strengthening.
