Abstract

The invention relates to a method for preparing a coating finishing agent for a textile from compound modified sepiolite, and belongs to the technical field of textile auxiliaries. The method for preparing the coating finishing agent for the textile from the compound modified sepiolite aims at the problems that polyacrylate is mainly used for a high molecular material of a current coating finishing agent, but is low in water pressure resistance, further, is poor in cold resistance, uncomfortable in hand feeling and low in elasticity; the high corrosion resistance, the radiation resistance, the good heat stability and the water absorptivity of sepiolite are utilized by the method for preparing the coating finishing agent for the textile from the compound modified sepiolite. First, the sepiolite is activated through high-temperature calcination, then is modified through an acid, and subsequently, is enabled to pass through hydrogen peroxide to oxidize the inside of the sepiolite and to remove impurities; afterwards, the antimicrobial properties of the coating finishing agent for the textile are increased through the sepiolite grafted, modified and screened by chitosan; meanwhile, the adhesive force of the coating finishing agent for the textile is increased; finally, by compounding the sepiolite with polyurethane, the water pressure resistance of the coating finishing agent for the textile is increased; the cold resistance and the elasticity of the coating finishing agent for the textile are improved; thus, the coating finishing agent for the textile prepared from the compound modified sepiolite is prepared.

(1) take meerschaum and put in calcining furnace, 1～2h is calcined at 600～700 DEG C, cool to 60～80 DEG C with the furnace, it is drawn off being soaked in the hydrochloric acid solution that mass fraction is 15%, stands 30～40min, filter, filtrate is put in baking oven and dry, use ball mill that the filtrate after drying is milled, cross 200 mesh sieves, collect the gained granule that sieves；
(2) by solid-to-liquid ratio 1:3, it is 30% hydrogen peroxide by the mass fraction of above-mentioned gained granule and its quality 10～15%, 10～15min are stirred at 300r/min, stand until producing without precipitation subsequently, remove impurity and the precipitated impurities swimming in the water surface, then carry out filtration under diminished pressure, use distilled water flushing filtrate 2～3 times, again filtrate is put in baking oven and dry, obtain pre-modified meerschaum granule；
(3) count by weight, take the pre-modified meerschaum granule of 50～60 parts of above-mentioned gained, 10～15 parts of chitosans, 1～2 part of lecithin and 4～6 parts of palladium carbon catalysts and put in reactor, stir, it is added thereto to pre-modified meerschaum granular mass 60～the acetic acid solution that mass fraction is 10% of 70% again, it is warming up to 80～90 DEG C, with 160r/min stirring reaction 6～8h；
(4) after above-mentioned reaction terminates, heating is stopped, the potassium hydroxide solution regulation pH to 7.0 that mass fraction is 30% is added to reactor, after being cooled to room temperature, carry out discharging and filter, use distilled water flushing filtrate 3～5 times, again filtrate is put in air-dry machine and air-dry, pulverize, cross 200 mesh sieves, obtain modified meerschaum；
(5) count by weight, take 45～50 parts of polyoxypropyleneglycols, 10～15 parts of triglyceride, the modified meerschaum of 25～30 parts of above-mentioned gained, 12～14 parts of oleum linis and 28～32 parts of toluene di-isocyanate(TDI)s, put in condensation reflux unit, design temperature is 100～110 DEG C, after being stirred at reflux 7～9h with 120r/min, by the residue in reflux and water 3:2 in mass ratio, mix homogeneously, i.e. can get fabric coating finishing agent.
