Abstract
This invention provides an aquosity organosilicon leather lubricant for meeting the request of brightness, endurance, dry touch, oil wettability and water-proof at one time, characterized in its active ingredient less than 18.0%, preference at 15-18%, PH higher than 4.0, preference; adopting organosilicon hydroxyl silicon oil, organosilicon amido oil, organosilicon polyether modified oil all catalyzed polymerization by organic acid accelerant, adding some dope, and using ion-free water self-emulsifying method to produce it.
Description
Technical field
The invention belongs to the leather chemical industry technical field, be specifically related to a kind of waterborne organic silicon smoothing agent for leather and preparation method thereof.
Background technology
The waterborne organic silicon smoothing agent for leather is an important materials in the leather production, it can significantly improve the feel of leather, make leather polishing, smooth, waterproof etc., the quality of waterborne organic silicon smoothing agent for leather performance is mainly reflected in weather resistance, smooth property, water-repellancy, and the leather hand feeling aspect after covering with paint, lacquer, colour wash, etc.
The waterborne organic silicon smoothing agent for leather is of a great variety, not following tens kinds of the waterborne organic silicon smoothing agent for leather product of the domestic and international different trades mark, their composition is nothing more than being outer emulsification of silicone oil or silicone hydrolysis, but, can satisfy the requirement that makes leather polishing, durable, smooth, glossy and waterproof simultaneously without any a kind in the at present commercially available waterborne organic silicon smoothing agent for leather product, they all are to give priority at some aspect of performances, therefore use the leather hand feeling aspect after currently available products is covered with paint, lacquer, colour wash, etc. not enough to some extent unavoidably.
Summary of the invention
Task of the present invention is at the deficiency of existing waterborne organic silicon smoothing agent for leather, and a kind of waterborne organic silicon smoothing agent for leather that can satisfy bright, durable, smooth, glossy and waterproof requirement simultaneously is provided; Another task of the present invention provides the preparation method of this waterborne organic silicon smoothing agent for leather.
A kind of waterborne organic silicon smoothing agent for leather provided by the invention is characterized in that effective ingredient≤18.0% of this waterborne organic silicon smoothing agent for leather, and is preferred 15～18%, pH value 〉=4.0, preferred 4.0～6.0.
This waterborne organic silicon smoothing agent for leather is with organosilicon hydroxy silicon oil, organosilicon amido silicon oil and organic silicon polyether modified silicon oil, through organic acid catalyst catalysis urge poly-after, after the adding by additive, adopt the self-emulsifying method preparation of deionized water, the prescription that this method adopts is:
Organosilicon hydroxy silicon oil 5～12%
Organosilicon amido silicon oil 5～12%
Organic silicon polyether modified silicon oil 2～5%
Organic acid catalyst 0.05～0.2%
Additive 0.1～0.3%
Deionized water 70～82%
Wherein the organosilicon hydroxy silicon oil is
The organosilicon amido silicon oil is
The organic silicon polyether modified silicon oil is
Organic acid catalyst is formic acid, acetate, oxalic acid.
Additive is effective ingredient 〉=99%.
The specific conductivity of deionized water 〉=300K Ω.
Waterborne organic silicon smoothing agent for leather provided by the invention prepares by following processing step and condition:
Organosilicon hydroxy silicon oil, organosilicon amido silicon oil and organic silicon polyether modified silicon oil input are answered in the still, add organic acid catalyst, additive and deionized water successively, and in 15～30 ℃ of temperature, react in 9 hours, can obtain waterborne organic silicon smoothing agent for leather provided by the invention.
Some performance index of products obtained therefrom are:
Effective ingredient≤18.0%
PH value 〉=4.0
The organosilicon hydroxy silicon oil can be contributed outstanding water-repellancy, smooth property, the organosilicon amido silicon oil can be contributed light and weather resistance, organic silicon polyether modified silicon oil, additive then can be contributed " self-emulsifying " performance, improve its stability of emulsion, organic acid catalyst then can promote to urge the acceleration of poly-reaction, therefore, waterborne organic silicon smoothing agent for leather provided by the invention is than more comprehensively having satisfied performance requriements bright, durable, smooth, waterproof.
