Description
Technical field
The present invention relates to metal conditioner technical field, particularly relate to a kind of interpolation silicon dioxide metal inorganic agent.
Background technology
According to statistics, have gross weight the most every year and be equivalent to the steel product of metal annual production 10-20% and cause and can not use due to reasons such as burn into corrosions, take various rust-proofing method to avoid corrosion for these people, reduce loss.The kind of antirust agent is varied, its Sodium Nitrite is favored because of its high rust resistance and cheap enjoying always and is widely used, but because other has the material of strong oncogene, therefore in the eighties in 20th century, just carry out substantial amounts of R&D work both at home and abroad, be prepared for the multiple material based on alkyl, alkoxyl, halogeno-group, naphthoic acid class and derivant thereof, nitrobenzoyl acids and borate, borate and molybdate etc. to replace the new type water-solubility antirust agent of sodium nitrite.Although these novel antirust agent relatively sodium nitrite more safe and reasonable, but during its film forming uses, there is more complicated striping and process problem, it is typically employed to aqueous alkali process, or process with the physical method such as bamboo knife and scraping blade, such process not only can not eliminate film it is also possible to damage metal surface, goes back work consuming time-consuming increase cost.Therefore along with the development of antirust technology, the application of antirust solution and film forming thereof is required also to gradually step up by people, occurs in that novel rust-preventing film, strippable property rust-preventing film.
Guo Jun proposes by adding antirust agent and other additives in polyvinyl alcohol in " development of the peelable rust-preventing film of PVA water soluble polymer " literary composition, place it in beaker and be heated to being completely dissolved in the thermostat water bath that temperature is 99 DEG C, recycling coating the tape casting is coated uniformly on metal surface, drying and forming-film, measure the performance of film, experimental result surface has good rust-preventing characteristic, in cold water below 40 DEG C, the most completely insoluble in water, but it is placed in the hot water of more than 40 DEG C, film can gradually deliquescing thinning, last all dissolvings, so limiting use region.The present invention is directed to this shortcoming and polyvinyl alcohol membrane modifying is improved the performances such as its water-fast, heat-resisting, oil resistant so that it is disclosure satisfy that the demand of multiple fields, make to reach more preferable rust-proof effect and corrosion protection period.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of interpolation silicon dioxide metal inorganic agent.
