Abstract
The invention relates to a leather finishing agent composition containing perfluoropolyethers. As a waterborne polyurethane leather finishing agent is compounded with perfluoropolyether grease, flexibility and smoothness of the leather finishing agent are improved; meanwhile, hydrophilic property of the leather finishing agent is improved with introduction of rare earth elements. Compatibility of various components is improved by using 1-ethyl acetate-3-methylimidazolium bromine ionic liquid.
Description
Technical field
The present invention relates to a kind of finishing agent, the leather finishing agent compositions of a kind of perfluoro-polyether.
Background technology
Leather finishing agent is the general designation covering with paint, lacquer, colour wash, etc. the class leather agent protecting and beautifying leather for leather surface, and it is by becoming
Membrane substance, coloured material, solvent and auxiliary agent are the most formulated, and wherein film forming matter is the base of leather finishing agent
Plinth.Leather finishing agent also has very important effect in leather manufacture industry, can increase leather attractive in appearance, when extending leather use
Between, hence it is evident that the quality of progressive leatherware and class, increase trade and be worth.
CN104530330A provides a kind of leather finishing agent, by γ-glycidyl ether oxygen propyl trimethoxy silicane, third
Alkene acid ester monomer, persulfate, casein, organic amine, water and sulphite prepare；Described acrylate monomer includes propylene
In acid butyl ester, ethyl acrylate, styrene and acrylonitrile more than three kinds.The invention provides the preparation of a kind of leather finishing agent
Method, uses casein that γ-glycidyl ether oxygen propyl trimethoxy silicane is modified uses modified with acrylate monomers again,
Containing epoxide group in γ-glycidyl ether oxygen propyl trimethoxy silicane, by modification, epoxide group is grafted to the big of casein
On molecule, there is condensation reaction with the polar group on casein side chain such as hydroxyl, amino, carboxyl etc., make the skin that the present invention provides
Leather finishing agent has preferable compliance and resistance to water；By the modification again of acrylate monomer, it is possible to improve this further
The compliance of the leather finishing agent that invention provides and resistance to water.
CN105256578A proposes a kind of anti-leather finishing agent of aqueous three and includes following raw material: the aqueous of low-surface-energy contains
Fluorine or silyl acrylate esters scopiform polymer, the fluorine-containing or siliceous linear polymer of hydroxyl reactive group, aqueous acrylamide
Esters of gallic acid polymer or aqueous polyurethane base polymer, water cross-linking agent and coalescents.Aqueous three anti-leather finishing agent water
Dispersion Environmental Safety, raw material sources are extensive, and the preparation method of three anti-leathers is simple, and three anti-leathers of preparation have excellent
Good Water-proof and oil-proof and antifouling property also have smooth feel.
Waterborne polyurethane coating agent is favored by users with its excellent elasticity, wearability and solvent resistance.So
And, the polyurethane coating elongation at break that currently known technology discloses is many between 600%～800%, and compliance is substantially than propylene
Acid resin class finishing agent is poor.Therefore, improve the compliance of finishing agent molecule, improve the elongation percentage of aqueous polyurethane film, it should be
One important research direction in polyurethane finishing agent field.
