Abstract

The invention discloses a steel plate weld cement seepage liquid salt trace conversion sealing treatment agent. The conversion sealing treatment agent comprises, by mass, 18-38% of phosphoric acid with the mass concentration of 85%, 0.1-0.8% of zinc oxide, 0.1-0.8% of potassium chlorate, 0.1-0.3% of nickel nitrate, 0.1-0.3% of tartaric acid, 0.1-1% of phytic acid, 0.1-1% of hydrofluoric acid, 1.5-3.5% of a silane coupling agent KH-560, 1.5-4.5% of triethanolamine, 1.5-4.5% of polyethylene glycol, 0.1-0.8% of a QYL-10F soak degreasing surfactant, and the balance of tap water. The conversion sealing treatment agent can effectively prevent a direct reaction of salt traces of sulfoaluminate and polycarboxylate and paint-based resin in a paint layer, avoids paint surface rusting or paint shedding, and guarantees the quality of products.

Description

Steel plate weld seam cement leakage liquid salt mark transforms sealing treatment agent and preparation method

Technical field

The present invention relates to a kind of steel plate weld seam cement leakage liquid salt mark and transform sealing treatment agent and preparation method.

Background technology

Cash Machine strong box was all adopt thickness to be the steel plate manufacture of 20 ~ 40mm substantially in the past, up-to-date Cash Machine strong box adopts double-deck assembly welding inside and outside cold-rolled steel sheet, pickled plate, and interlayer pouring contains the cement solidification layer of a large amount of sulplo-aluminate and polycarboxylate special formulation 80 mm thick.Processing requirement: all welded seam all can not be continuous must be discontinuous form; After cement layer pouring ambient cure in 24 hours, the process of surface treatment that lower road carries out process stipulation can be proceeded to; The whole spray-coating of the surfaces externally and internally of strong box specifies paint, because of special formulation cement solidification layer, the air-dry temperature of the high pressure after spray-coating does not allow more than 85 DEG C.Thus, cement layer ambient cure 24 hours, and the baking in rear road is no more than many reasons such as 85 DEG C, even if all complete processing also can not ensure that the moisture in the cement layer of 80 mm thick all vapors away after terminating.The continuity of moisture in cement layer along with the time and the change of temperature, just leak out gradually from weld seam discontinuities, and taken cement salt mark out of.These cement salt marks can destroy the paint film of weld seam periphery gradually, and painted surface is got rusty, and even cause weld seam periphery paint film to come off, have had a strong impact on quality product.

Summary of the invention

The present invention is the above-mentioned technical problem in order to solve existing for prior art, provides a kind of steel plate weld seam cement leakage liquid salt mark to transform sealing treatment agent and preparation method.

Technical solution of the present invention is: a kind of steel plate weld seam cement leakage liquid salt mark transforms sealing treatment agent, it is characterized in that raw materials used and mass percent is as follows: the phosphatase 11 8 ~ 38% of mass concentration 85%, zinc oxide 0.1 ~ 0.8%, Potcrate 0.1 ~ 0.8%, nickelous nitrate 0.1 ~ 0.3%, tartrate 0.1 ~ 0.3%, phytic acid 0.1 ~ 1%, hydrofluoric acid 0.1 ~ 1%, silane coupling agent KH-5601.5 ~ 3.5%, trolamine 1.5 ~ 4.5%, polyoxyethylene glycol 1.5 ~ 4.5%, QYL-10F soak degreasing tensio-active agent 0.1 ~ 0.8%, tap water surplus.

A kind of above-mentioned steel plate weld seam cement leakage liquid salt mark transforms the preparation method of sealing treatment agent, it is characterized in that carrying out in accordance with the following steps: add in stainless steel cauldron by calculating the tap water weighed, start agitator, control rotating speed 40 ~ 50 revs/min, then successively calculating the phosphoric acid weighed, zinc oxide, Potcrate, nickelous nitrate, tartrate, phytic acid, hydrofluoric acid, silane coupling agent KH-560, trolamine, polyoxyethylene glycol, QYL-10F soak degreasing tensio-active agent joins in reactor slowly, stir while adding, until solution is greenish transparent liquid.

Invention can before high pressure be air-dry, adopts pressure plastics watering can to spray all weld seam peripheries, especially sprays weld seam gap, namely to the position of seepage cement salt mark having carried out conversion sealing treatment,

Effectively can stop the salt mark of Sulphur in Cement aluminate and polycarboxylate directly and paint base resin in coat of painting and react, avoid painted surface to get rusty or peeling paint, ensure that quality product.
