Description

The application of brightener pigment in washing composition or sanitising agent
The present invention relates to the application of brightener pigment in improving washing composition or sanitising agent, its compound and each raw-material whiteness, this brightener pigment contains:
(a) a kind of insoluble polymer and
(b) a kind of water soluble fluorescence whitening agent.
Component (a) can be the solid polymer of the high dispersing that is combined to form by polyreaction, polycondensation or polyaddition reaction or these reactions for example.In GB-A-1 323 890, described this base polymer, comprised polycondensate, aminoplastics polycondensate especially, for example urea formaldehyde and carbamide polymkeric substance, and vinyl polymer, for example polyacrylonitrile.
Preferably, a kind of water-insoluble urea-formaldehyde resin used according to the invention, wherein the mol ratio of urea and formaldehyde is preferably 1: the 1.3-2 mole.The feature of this urea-formaldehyde resin also comprises small particle size and the 15-120m of 2-10 μ m 2The low BET specific surface of/g.
The BET specific surface of preferred water-insoluble urea-formaldehyde resin be according to Brunauer, Emmentt and Teller method [referring to JACS(j.Am.Chem.Soc.) 60, 309-319 (1938), chemistry-slip-stick artist-technology (Chemie-Ing.-Techn.) 32, 349-354 (1960) and 35, 568-589 (1963)], determine according to Deutsche Industry Norm (DIN) 66132.
It is known being equivalent to the preferred water-insoluble urea-formaldehyde resin of component (a) and the preparation method of these polymkeric substance, for example can be by A.Renner, Macromolecular chemistry(Makromolekulare Chemie) 149, 1-27 (1971) learns.
Preferred ingredients (a) compound can be by formaldehyde and urea with aforementioned proportion prepared in reaction in the aqueous solution.Reaction is preferably carried out in two steps.In the first step reaction, urea and formaldehyde form low-molecular-weight water-soluble precondensate according to common condensation mechanism reaction.In the reaction of second step, acid catalyst can be used so that accelerated reaction and crosslinked obtains finely divided insoluble solid.
During the insoluble polymer particle precipitation, the water-content in the reaction soln should be not less than the reactant gross weight that exists in the reaction mixture, and is not higher than the gross weight of all other components in the reaction mixture.
Temperature of reaction in the first step reaction is generally 20-100 ℃.Can be by adding the inorganic strong alkali aqueous solution, for example sodium hydroxide solution arrives 6-9 with pH regulator.
Precondensate can advantageously be prepared in the presence of tensio-active agent.The consumption of tensio-active agent is for example 0.5-5% of urea and formaldehyde gross weight.Ionogenic surfactant can make the specific surface of agroform product increase, and the effect of nonionic surface active agent is opposite.
The first step is reflected at the water-soluble macromolecule protective colloid with polyelectrolyte character and compares under existing favourable.The example of this class protective colloid comprises gelatin, tragacanth gum, agar and polyvinylpyrrolidone, especially methacrylic acid.The consumption of protective colloid can be the 0.5-5% of urea and formaldehyde gross weight.Be that polyvinylpyrrolidone or polymethyl acrylic acid can not make the specific surface of water-insoluble urea-formaldehyde resin increase.
Successfully preparation meets one of the most important condition of not molten, insoluble and finely divided agroform of the specification of quality of the brightener pigment that uses among the present invention, is the suitable catalyzer that is used for gel formation of use in the reaction of second step.Appropriate catalyst for example comprises stronger inorganic and/or organic acid relatively, for example, and sulfuric acid, sulfurous acid, thionamic acid, phosphoric acid, hydrochloric acid, Mono Chloro Acetic Acid, toxilic acid or maleic anhydride.In general, this class gelatin formation catalyzer should have the ionization constant above 10-4.Preferably sulfuric acid and acid ammonium salt or amine salt, and ammonium sulfate, hydrogen sulfate methylamine and hydrogen sulfate thanomin.The consumption of acid is generally the 1-15% of aqueous solution weight.Say every mole of urea crosslinking catalyst of 20-100 mmole roughly.This makes second pH that goes on foot reaction mixture in the reaction of polymer formation process reduce 1 to 3.0.
When using carboxylamine, obtain the higher relatively water-insoluble urea-formaldehyde resin of specific surface usually, above-mentioned other acid, especially sulfuric acid and ammonium salt or amine salt have opposite effect.
Form in the reaction of resin in second step, temperature of reaction often reaches 20-100 ℃.During adding catalyzer, should avoid that the big temperature difference is arranged in the reaction mixture.Therefore be heated to the temperature of reaction mixture before wishing to join aqueous catalyst solution in the mixture earlier.Generally, just obtain white gels after second at 15-30 only.Crosslinking reaction finished after about 30 minutes to 3 hours usually.
Insoluble polymer is that the form with white gels obtains, can be with its mechanical grinding, the water treatment with approximate equivalent is adjusted to pH 6～9 with alkali or ammonium hydroxide, is separated by aqueous phase then, for example utilize filter, centrifugal or evaporation concentration method separates.Drying can be carried out with spraying drying or convection drying method.
Then with the gel that obtains with the usual way aftertreatment, for example the order reaction is carried out fully, neutralization, add the back when needing and after gelling, just add one or more white dyess that the situation of white dyes is mentioned, filter then, wash, drying, if desired, levigately obtain suitable size of particles.
