Abstract
The invention discloses a novel normal-temperature phosphating solution and relates to the technical field of rubber product phosphating. The novel normal temperature phosphating solution is characterized by comprising the following components of, by weight, 30-50 parts of a film-forming agent, 10 parts of zinc dihydrogen phosphate, 5 parts of calcium nitrate, 1-2 parts of an accelerant and 0.2-0.3 part of a surface active agent. By means of the novel normal temperature phosphating solution, the rubber bushing product phosphorization is stable, bath solution sediment is little, the environmental pollution is small, and it is the most important that the consumption of the phosphating solution is low, the manufacturing cost is reduced, and the production efficiency is improved; the expense of secondary treatment due to disqualification of product phosphorization and the risk of bonding failures are avoided.
Description
Technical field:
Invention relates to rubber product phosphorization technology field, specifically a kind of novel normal-temperature phosphorizing liquid.
Background technology:
Temperature, cryogenic product phosphatization during current rubber industry majority adopts; chemical reaction can be produced with the wax in rubber in certain temperature (40 DEG C), allow a wax precipitation part be dissolved in tank liquor; thus make that tank liquor pollutes, phosphoric acid salt and metallic surface can not normally form phosphate coating and be attached to metallic surface; normal-temperature phosphorizing liquid is wax in normal room temperature not dissolving rubber, and phosphate coating directly reacts with metallic surface and generates phosphate coating, crystalline state densification.
Summary of the invention:
The technical problem that invention will solve is to provide one, is convenient to phosphorization filming, and phosphatization tank liquor sediment is few, the volatilization of "dead" material, and speed is fast, and it is high that product phosphatization output once drops into qualification rate.
Solve technical problem adopt following technical scheme:
A novel normal-temperature phosphorizing liquid, is characterized in that: comprise following component by weight,
Membrane-forming agent 30 ~ 50 weight part
Primary zinc phosphate 10 weight part
Nitrocalcite 5 weight part
Promotor 1 ~ 2 weight part
Tensio-active agent 0.2 ~ 0.3 weight part.
Described membrane-forming agent comprises zinc oxide 10 ~ 15 weight part, zinc nitrate 20 ~ 40 weight part.
Described promotor comprises nickelous nitrate 0.3 ~ 0.4 weight part, citric acid 0.3 ~ 0.4 weight part, Sodium Fluoride 0.2 weight part, Sodium orthomolybdate 0.3 weight part, Sodium Nitrite 0.2 weight part.
The acid of described Phosphating Solution is than being 1:20-25.
Described tensio-active agent comprises Witco 1298 Soft Acid 0.2 ~ 0.25 weight part, wilkinite 0.03 ~ 0.05 weight part.Can adjust ph, the active center of rubber surface can be increased, be conducive to the carrying out of phosphating reaction.Accelerate phosphatization, improve phosphatization quality, itself becomes emulsification shape, accelerates phosphatize phosphate coat and is formed, increase thicknesses of layers.Wilkinite not only plays the effect of tensio-active agent, and the effect simultaneously can playing emulsifying agent increases the viscosity of Phosphating Solution, and wilkinite can improve its salt-fog resistant time as tensio-active agent for the rubber after phosphatization.
Normal-temperature phosphorizing liquid of the present invention adapt to all rubber bushings product, to the performance (Static stiffness) of rubber bushing without any change, often there is metallic surface, endoporus jaundice, get rusty in middle temperature, low temperature phosphor product, thus antirust weak effect after causing rubber bushing product phosphatization, affect product and normally pay or assemble;
For effective antirust problem, the assembling of operation in time after solution product phosphatization, the technical scheme of normal temperature phosphating of the present invention is:
Tank liquor after New Ambient Temperature Phosphating Solution proportioning does not need the good stability of heating, tank liquor concentration, and thickness compact crystallization, metal salt-fog resistant test are better than the salt fog time of medium temperature phosphating solution, Low-Temperature Phosphate Liquid;
The sediment of medium temperature phosphating solution, sediment at the bottom of Low-Temperature Phosphate Liquid two kinds of product phosphatization pits and heating tube attachment sharply increased along with the time used, and the stability of concentration difference phosphatization skeleton of tank liquor, phosphatization rubber bushing product all have sediment to adhere to cause metallic framework surface to turn white, be wounded in action.
The beneficial effect of the invention is: phosphatization rubber bushing product stability is good, and temperature on year-on-year basis, low temperature phosphor tank liquor sediment is few; The volatilization of "dead" material, it is high that product phosphatization output once drops into qualification rate.
Embodiment:
The technique means realized to make invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific examples, setting forth invention further.
