Abstract
The invention discloses an oil concrete additive, making method and using method in the architectural material technical domain, which is characterized by the following: adopting bisphenol A typed epoxide resin as base resin and low-molecular polyamide as hardener; adding PVC resin as oil-adsorbing fill; adopting ethinyltrichloride or chloroform as surface processor; obtaining the product with maximum positive strength at 1.91-3.14Mpa.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of oily soil surface concrete adhesive, preparation method and using method.
Background technology
The crack of concrete building structures, breakage are ubiquitous problems, and it is aging that data shows that China has at least 40% concrete structure to face, undercapacity, the problem that weather resistance and security are low excessively, need improve weather resistance to these structural strengthening and repairings, guarantee normally to use.Adopting polymkeric substance or polymer mortar is more advanced concrete structure recovery technique at present, and having bonding, stressed evenly cohesive force is strong, and is easy to use, short construction period, plurality of advantages such as it is in extensive range to bond.But concrete structure in factory, workshop and oil storage facility is in case generation damages or cracking tends to by oil pollution.Just can't remove because in a single day concrete porous structure, greasy dirt infiltrate, greasy dirt kind in the while varying environment, greasy dirt content is had nothing in common with each other again, and these are all given and use the damage of general polymer rehabilitating concrete to cause very big difficulty.
The bonding of greasy dirt flooring results from automotive industry the earliest, and its use can be removed degreasing metal surface from, and steps such as cleaning are saved cost, raise the efficiency.Pasta glue in using at present mainly is divided into 4 types: chlorine dibutyl glue kinds putty type tackiness agent, polyvinyl chloride (PVC) RESINS class putty type tackiness agent, epoxies tackiness agent, modified acrylic ester adhesion agent.
Above adhesive for oily surface generally is used for the surface has the smeary metal with the bonding between other cleaning materials, and service requirements metal surface greasy dirt thickness is not more than 25 μ m.But the matrix material of oil-containing concrete structure does not appear in the newspapers as yet.
Summary of the invention
The object of the present invention is to provide a kind of oily soil surface concrete adhesive, preparation method and using method.
The oily soil surface concrete adhesive that the present invention proposes is made up of Resins, epoxy, solidifying agent, coupling agent, oil-absorbing resin and surperficial molten finish, and each composition weight umber is:
The composition weight umber
Resins, epoxy 100
Solidifying agent 40～70
Coupling agent 4～6
Oil-absorbing resin 30～40
Molten oil assistant is an amount of.
Among the present invention, can also add proper amount of diluting.
Among the present invention, described thinner is reactive thinner 501 (epoxy propane butyl ether).
Among the present invention, described Resins, epoxy is bisphenol A type epoxy resin, as Resins, epoxy E-51 etc.
Among the present invention, described solidifying agent is a low molecular polyamides, as polyamide 6 51 etc.
Among the present invention, described coupling agent is a silane coupling agent, as KH-550 etc.
Among the present invention, described oil-absorbing resin is a polyvinyl chloride resin, sticks with paste P450 etc. as polyvinyl chloride resin.
Among the present invention, the molten oil assistant in described surface is trieline or chloroform etc.
The preparation method of the oily soil surface concrete adhesive that the present invention proposes, concrete steps are: accurate by weight ratio weighing Resins, epoxy, solidifying agent, coupling agent and thinner (the thinner consumption suitably changes according to environment for use or do not use), place container to stir, add oil-absorbing resin again, putting into mortar after stirring grinds, until the resin homodisperse, promptly get desired product.
The using method of the oily soil surface concrete adhesive that the present invention proposes, concrete steps are:
(1) zone of damage is arranged for the surface, dry the molten oil assistant of spraying behind the surperficial oil stain earlier, pour the tackiness agent colloid then into until filling up defect area.
(2) for the distress in concrete zone, dry up residual greasy dirt in the seam with air compressor earlier, the molten oil assistant of sprayed surface adopts pumping injection or hand dropping mode to pour into tackiness agent according to the fracture spaces position at last again.
The present invention has following advantage:
1, can solidify existing under the smeary environment, solidify the back concrete material is had higher cohesive force.General greasy dirt concrete is just drawing cohesive strength can reach 1.91～3.14MPa.Can be used for factory, the grouting leak-stopping and the reinforcement of workshop and oil storage place concrete structure damage reparation or distress in concrete.
2, starting material are Industrial products, be simple and easy to, preparation is convenient, can be according to concrete degree of impairment with using with joining, and constructing operation is easy.
3, be widely used, for common lubricating oil, sewing-machine oil, the concrete of the different pollution by oils of hydropress wet goods all has unusual effect.
