Abstract
The invention relates to a synthetic method of hydrophilic silicon oil for treating the surface of leather. The synthetic method comprises the steps of adding 10-15 parts by weight of allyl alcohol polyoxylethylene ether, 0.005-0.015 part by weight of a catalyst and 0.8-1.5 parts by weight of a solvent into a flask, stirring uniformly, heating, controlling the temperature to be 80-120 DEG C, dropwise adding 10-15 parts by weight of hydrogen-containing silicon oil into the flask under the protection of nitrogen of which the concentration is more than 99.9%, and reacting for 4-8 hours at a constant temperature of 70-120 DEG C to obtain clear, colorless and transparent hydrophilic silicon oil. The hydrophilic silicon oil prepared by the method disclosed by the invention can improve the leveling property, comfort and softness of leather, and the problems and defects of the prior art are solved.
Description
Technical field
The present invention relates to a kind of synthetic method of processing the hydrophilic silicon oil of leather surface, belong to chemical field.
Background technology
Leather industry is developed rapidly in recent years, people are more and more higher to the requirement of leather products, as require leather light, thin, soft, and there is silk-like handle, kishke feel is strong, feel is smooth, plentiful and flexible, chromatogram is complete, and dyeing firmly and have waterproof, a performance such as fast light, antifouling, all these requirements, need to be by the realization that should be used for of leather treatment.
Although synthetic leather goods have certain ventilation property, be difficult for mouldy, waterproof, acid and alkali-resistance.But its feel often astringent, plate is hard, affects its comfortableness, so leather carries out softening and is very important.Although conventional amido silicon oil soft finishing agent has improved the pliability of leather largely, improve its feel; But because amido silicon oil has sealed the hydroxyl that part fiber has itself, the intrinsic wetting ability of leather itself is declined to some extent, thereby affect its wearing comfort and flexibility.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of synthetic method of processing the hydrophilic silicon oil of leather surface, and hydrophilic silicon oil prepared by the present invention can be improved levelling property, comfortableness and the flexibility of leather, solves problems of the prior art and defect.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of synthetic method of processing the hydrophilic silicon oil of leather surface, comprise: in flask, add the allyl alcohol polyethenoxy ether of 10～15 weight parts, the solvent of the catalyzer of 0.005～0.015 weight part, 0.8～1.5 weight part, stir, heating, temperature is controlled at 80～120 ℃, in concentration, be greater than under 99.9% nitrogen protection, the containing hydrogen silicone oil of 10～15 weight parts is added drop-wise in flask, and react 4～8h under 70～120 ℃ of constant temperature, obtain clarifying water white hydrophilic silicon oil;
Wherein, the general structure of described hydrophilic silicon oil is as follows:
In formula, a=1-20, q=1-30;
The structural formula of described allyl alcohol polyethenoxy ether is as follows:
In formula, a=1-20;

Described solvent is one or more the mixing in Virahol, propyl carbinol, isopropylcarbinol, ethylene glycol, polyoxyethylene glycol, tetraethylene-glycol;
Described containing hydrogen silicone oil structural formula is as follows:
On the basis of technique scheme, the present invention can also do following improvement.
Further, described catalyzer is Virahol platinum acid chloride solution;
Further, described solvent is polyoxyethylene glycol or tetraethylene-glycol; The preferential tetraethylene-glycol that uses.
Reaction formula is as follows:
The invention has the beneficial effects as follows:
The hydrophilic silicon oil that synthetic method of the present invention is synthetic, wherein its good wetting ability is given in polyethers link, therefore need not use can well be scattered in the situation of any emulsifying agent in water, to form the stable aqueous solution; And hydroxyl wherein by with isocyanate reaction, with the form of segmented copolymer, organosilicon is combined with resin system, thus the smooth and soft surface of significantly improving.After reaction finishes, need not can obtain hydrophilic silicon oil except desolventizing.
