Description
Technical field
The present invention relates to a kind of chemical reagent and preparation technology thereof, particularly a kind of without phosphorus silane coupling agent.
Background technology
Bonderizing is a kind of technology being applied to anti-corrosion of metal, and be applicable to the Coating Pretreatment of iron and steel, Al and Alalloy, zinc and zinc-plated, galvanized alloy part and magnesium alloy member, namely it be widely used from twentieth century.But there is following shortcoming in bonderizing: 1. metal and phosphate reaction can produce a large amount of mud and phosphorus dirt; 2. need to control the parameters such as free acid, total acid, promotor, zinc, manganese, nickel, control loaded down with trivial details; 3. contain phosphorus, heavy metal in waste water, the bonderizing complex procedures time is long, and comprehensive production cost is high.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of alternative parkerized without phosphorus silane coupling agent, the mud a large amount of with the above-mentioned generation solving prior art existence and phosphorus dirt, control loaded down with trivial details, containing phosphorus, heavy metal in waste water, the bonderizing complex procedures time is long, the weak point that comprehensive production cost is high.
The technical scheme solved the problems of the technologies described above is: a kind of without phosphorus silane coupling agent, comprise the amides of calculate by mass percentage 12 ~ 15%, 3 ~ 5% octadecyl amine salt, the ethers of 0.2 ~ 0.5%, the silane of 10 ~ 15% and surplus water.
Further technical scheme of the present invention is: described amides is a kind of or several arbitrarily combination in lauric acid diethyl amide or diglycollic amide or fatty diglycollic amide.
Further technical scheme of the present invention is: described octadecyl amine salt is one or both combinations in octadecylamine acetate or octadecylamine.
Of the present invention more further technical scheme be: described ethers is one or both combinations in polyvinyl ether or fat alcohol polyethylene ether.
Owing to adopting said structure, the without phosphorus silane coupling agent of the present invention compared with prior art, has following beneficial effect:
1. alternative bonderizing:
Due to the present invention includes calculate by mass percentage 12 ~ 15% amides, 3 ~ 5% octadecyl amine salt, the ethers of 0.2 ~ 0.5%, the silane of 10 ~ 15% and surplus water; Each moiety hybrid reaction formed have simultaneously can and the chemically combined reactive group of inanimate matter material and the reactive group that is combined with organic materials chemistry, may be used for surface treatment.Therefore, the alternative bonderizing of the present invention, for the surface anticorrosion of metal works; And the metallic surface after the without phosphorus silane coupling agent process of the present invention is with compared with parkerized metallic surface: 1. outward appearance is suitable, be all in faint yellow; 2. the without phosphorus silane coupling agent in neutral salt spray test aspect is more anti-corrosion than phosphatization.
2. can avoid producing a large amount of mud and phosphorus dirt:
Because this without phosphorus silane coupling agent is not phosphorous, chromium, avoid metal and phosphate reaction and produce a large amount of mud and phosphorus is dirty.
3. wastewater treatment is simple:
Without phosphorus silane coupling agent due to the present invention can be avoided producing a large amount of mud and phosphorus dirt, and its treatment process is simple, and comprehensive production cost is lower.
4. treatment effect is good:
Have excellent solidity to corrosion through the metallic surface of the silane coupling agent process of the present invention, good to the sticking power of organic coating, its effect is more excellent than bonderizing.
Below, the technical characteristic of the without phosphorus silane coupling agent of the present invention is further described in conjunction with the embodiments.
