Description
Technical field
The present invention relates to a kind of chemical industry mill base that is used for spinning coating, synthetic leather industry and preparation method thereof.
Background technology
Traditional oil pastes is because the use of organic solvent is far longer than aqueous color paste to environment damage with to the able-bodied harm of workman.In recent years also because aqueous polyurethane and latex are increasing in spinning coating, synthetic leather industry usage quantity, so the painted welcome that more and more is subjected to people of use mill base.The aqueous color paste that now is used for spinning coating, synthetic leather industry on the market, because single carrier series mill base is difficult to and spinning coating, the various performances of use for synthetic leather, the resin compatible of kind, cause having only the corresponding and single coloring resin of single serial mill base, single serial mill base can not be general in spinning coating, the various resins of synthetic leather industry.
Summary of the invention
The object of the present invention is to provide a kind of precipitation that in water, is difficult for, steady in a long-term and with the waterborne general color paste of various water-based spinning coatings, synthetic leather resin compatible.
Another object of the present invention is to provide the preparation method of this waterborne general color paste.
Waterborne general color paste of the present invention, composed of the following components by weight percentage:
Deionized water 30-50% emulsifying agent 5-10% toner 25-40%
Dispersion agent 2-5% defoamer 1-5% mould inhibitor 0.1-2%
Wetting Agent for Printing Inks 1-5% frostproofer 1-5%.
Wherein, deionized water plays the various auxiliary agents of dissolving, toner as solvent; Emulsifying agent can play emulsifying effect in water, a kind of carrier promptly is provided; Toner plays painted effect; Dispersion agent can make toner homodisperse in system, helps grinding; Defoamer is used for preventing the whipping process phenomenon of bubbling; Mould inhibitor prevents that mill base is mouldy because of long-time placement; The volatilization of the anti-sealing of wetting Agent for Printing Inks; Put and freeze agent and prevent that mill base from luming at low temperatures.
The preferred content of deionized water is 36-42% in the above-mentioned composition; The preferred content of emulsifying agent is 6-7%; The preferred content of toner is 32.9-37.9%; The preferred content of emulsifying agent is 6-8%; Wherein emulsifying agent is tributyl phenol Soxylat A 25-7, styroyl phenol polyethenoxy ether; Dispersion agent is Sodium hexametaphosphate 99, tripoly phosphate sodium STPP; Defoamer is tributyl phosphate, phenylethyl alcohol oleic acid ester; Mould inhibitor is sodium pentachlorophenate, hydroxybenzoate; Wetting Agent for Printing Inks is ethylene glycol, glycerine; Frostproofer is glycol ether, alkyl succinimide.
The method for preparing waterborne general color paste of the present invention, this method comprises the steps:
1. with in 70% the deionized water adding reactor, add emulsifying agent, dispersion agent, stir, add toner then, stir half an hour, make its preliminary dispersion;
2. with above-mentioned preliminary dispersive mill base, put into three-roll grinder and grind, get the higher work in-process mill base of viscosity;
3. remaining deionized water is joined in the above-mentioned work in-process mill base, add defoamer, stir;
4. add wetting Agent for Printing Inks, frostproofer, mould inhibitor after stirring, stirred 10-30 minute;
5. after stirring, filter, promptly get waterborne general color paste of the present invention.
The present invention compares with existing various spinning coatings, use for synthetic leather aqueous color paste, and mill base can form smooth dry film, and mill base viscosity improves, and mill base can be placed and not mouldy for a long time, and mill base does not lump at low temperatures; Have characteristics such as applied widely, that consistency is good, standing storage is stable; Be applicable to that various spinning coatings, synthetic leather are painted; Simultaneously owing to be aqueous color paste, so the viscosity of mill base can be not enough, general all is the viscosity that increases aqueous color paste by the adding thickening material, but adding thickening material at first is to have increased cost, and mill base lumps easily behind the adding thickening material,, the present invention reaches the adjusting of the slurry viscosity of checking colors so not adding thickening material by the content of adjusting emulsifying agent, the present invention determines the content of emulsifying agent by a large amount of experiments, both made toner can be good at being suspended in deionized water, in the system that emulsifying agent forms, the viscosity of whole mill base is suitable simultaneously, at spinning coating, can be in the leather printing because of the viscosity of mill base too high and influence printing.
