Abstract

The present invention discloses an anticorroscon water-proofing treatment method for steel or formed cement surface and its surface treatment. Said treatment is made up by mixing 2%-20% of polyurethane with 5%-25% of anthracene oil, adding 40%-85% of toluene and 40%-85% of xylene, and further adding 2%-10% of toughening agent and plasticizer. After said treatment is applied on the steel or formed cement surface, the residual paint and asphalt on the steel material or moisture content on the cement surface can be reacted with the treatment to form transition layer, then the transition layer is combined with said anticorrosion water-proofing coating to produce very strong cohesive force so as to greatly raise the anticorrosion water-proofing property of steel material or cement surface, and its construction is simple and cost is low.

Description

A kind of surface anticorrosion method for waterproofing and surface treatment agent

The present invention relates to the chemical industry paint field, relate in particular to a kind of steel or anticorrosion method for waterproofing of moulding cement surface and surface treatment agent of being used for.

As everyone knows, all kinds of buildingss that people's orthobiosis and work are used, comprise industrial building, civil building and bridge buildings, all be to constitute by steel and this two big material of construction of cement, and all kinds of buildingss all the corrosion-resistanting waterproofing performance of requirement itself is strong, so that increase its work-ing life, just seeming extremely important as the steel of building foundation material and the anticorrosion and waterproof of cement. steel are anticorrosion generally to be in its anticorrosion purpose that clean Surface coating oil drop is oily or other organism coating reaches, the shaping cement water-proof also is that especially surface applied organism coating is carried out WATER REPELLENT, the bonding force of organism coating and steel and cement surface just becomes anticorrosion waterproof key of success, if steel surface oil, paint or other organic vestiges, then can influence the bonding force of corrosion protection coating, these vestiges of removing steel surface generally are to select for use organic solvent to clean, but poor effect, also have steel surface is sprayed the noisy method of handling, this method, price height not only, and contaminate environment, be difficult to again make in this way in some working-yard, and it is unprocessed or handle bad steel surface and directly influence preservative effect, and the waterproof organism coating of shaping cement needs could apply behind the cement complete drying, because cement long construction period increase and the cement exsiccant degree of causing time of drying is difficult for again grasping, as applying water-proof coating at undried cement surface, then the moisture content in the cement can influence the waterproof effect of water-proof coating.

The treatment process and the surface treatment agent that the purpose of this invention is to provide the anticorrosion or waterproof of a kind of steel or moulding cement surface, this treatment process and surface treatment agent, can make without the steel surface of special processing and the moulding cement surface and the anticorrosion water-proof coating of undried and produce stronger cohesive force, thereby improve the anticorrosion waterproof ability of steel or moulding cement.

In order to achieve the above object, the present invention by the following technical solutions, at steel surface and moulding cement surface coated surfaces treatment agent, this treatment agent is not to clean steel surface, neither absorb the moisture content of cement surface for drying, but and multiple organic substance reactions such as the pitch on steel or the moulding cement surface, water, paint fused, form the organism coating, transition layer as steel and moulding cement surface and anticorrosion water-proof coating, on transition layer, apply epoxide coal bituminous again or other organism coating, constitute anticorrosion and waterproof layer.Surface treatment agent is to give polymers by the urethane of 2W---20% or urethane to mix with 5%2596 the oil of fearing, the adding toluene of 40---85% and the dimethylbenzene of 40W'---85%, and it is formulated to add 2%----10% toughner and softening agent again.Wherein: the preferred ingredient that urethane or urethane give polymers is 5W--10%, and the preferred ingredient of carbolineum is 10%---20%, also can add tensio-active agent in right amount as additive.

Because the present invention has adopted the technical scheme of having used surface treatment agent to form the organism transition layer on the surface of steel or moulding cement, make bonding force anticorrosion or water-proof coating and steel or moulding cement surface improve greatly, reached the purpose that improves the anticorrosion and cement water-proof performance of steel, and construction is simple, cost reduces, and does not produce dust pollution.

Below in conjunction with embodiment in detail the present invention is described in detail, involved per-cent by weight percentage:

Urethane with 8% mixes adding 30% toluene, 45% dimethylbenzene and adds 45% toughner again with 8% the oil of fearing, 45% softening agent, constitute and divide surperficial treatment agent, this treatment agent is coated on the steel or moulding cement surface of having removed bulk material, formed transition layer through 30 minutes after the drying, on transition layer, get final product asphalt-coating or other organic substance, thereby constitute anticorrosion or waterproof layer.

Claims

1. treatment process that is used for steel or the anticorrosion waterproof of moulding cement surface, it is characterized in that: at steel surface and moulding cement surface coated surfaces treatment agent, this treatment agent is not to clean steel surface, neither absorb the moisture content of cement surface for drying, but and multiple organic substance reactions such as the pitch on steel or the moulding cement surface, water, paint fused, form the organism coating, transition layer as steel and moulding cement surface and anticorrosion water-proof coating, on transition layer, apply epoxide coal bituminous again or other organism coating, constitute anticorrosion waterproof layer.

2. realize the surface treatment agent of the described treatment process of claim 1, it is characterized in that: described surface treatment agent is wide by 2%--20% urethane or urethane give polymers to be mixed with 5%25% the oil of fearing, add the toluene of 40--85% and the dimethylbenzene of 40%---85%, it is formulated to add 2%10% toughner and softening agent again.

3. according to the described surface treatment agent of claim 2, it is characterized in that: the preferred ingredient that described urethane or urethane give polymers is 59cr--10%, and the preferred ingredient of carbolineum is 10%20%.

4. according to the described surface treatment agent of claim 2, it is characterized in that: also can add an amount of tensio-active agent as additive.
