Abstract
The present invention relates to the technical fields of high molecular material, more particularly to a kind of aqueous polyurethane, including the following raw material: polynary amino alcohol, isocyanic acid, thermoplastic polyurethane elastomer, chain extender, neutralizer, deionized water and hydrazine hydrate, polynary amino alcohol is diethylaminoethanol, 3- amino -1,2- propylene glycol or 3- lignocaine -1- propyl alcohol, the dosage of neutralizer is that the pH of control mixed liquor is 7.5-9, has the advantages that wear-resisting, water resistance is good and wellability is good；The aqueous polyurethane that castor oil is added is additionally provided, the wellability of aqueous polyurethane is further improved；Additionally provide the preparation method of dumb light aqueous polyurethane after two kinds of aqueous polyurethanes to be added to flatting silicas and preparation method thereof and two kinds of aqueous polyurethanes, the dumb light aqueous polyurethane made, while improving leather surface gloss, delustering agent can be made not to be stripped out from film, extend the effective acting time of flatting silica.

The present invention relates to the technical fields of high molecular material, and in particular to a kind of aqueous polyurethane, dumb light aqueous polyurethane
And preparation method.
Background technique
A large amount of leathers are used in automobile, luggage and shoe-making field, to improve leather surface aesthetics, corrosion resistance and wear-resisting
Performance often uses coating and carries out top finishing.
Synthetic Leather is the most promising natural leather substitute after artificial polyvinyl chloride leather.Synthetic Leather
It compensates for artificial polyvinyl chloride leather and substrate adhesive fastness is poor, be easy to peel off, the disadvantages of feel is stiff has gloss naturally soft
With, adhesive property is good, it is wear-resistant the advantages that.
Existing low gloss leather finishing agent mostly uses greatly waterborne polyurethane resin, and aqueous polyurethane is a kind of plastic particle
Evenly dispersed thinlyfluid in water forms the sequential like being evenly distributed by fusion between polymer particles and applies when in use
Film；When film forming, show especially with the volatilization of solvent, the thinning silica dioxide granule for shrinking, being suspended in resin of film in film item
Layer forms a micro-roughened surface, which can make incident light, thus obtain low gloss effect with
Soft sense of touch.But it is monomer that current aqueous polyurethane, which mostly uses polyether polyol, water resistance is poor with wearability；And its
Wellability is poor, although can obtain low gloss effect by the delustering agent for adding such as silica etc, with pushing away for time
It moves, these duller particles are easy to be stripped out from film, thus bring to the weatherability of film and ultraviolet-resistant performance
Negative effect.
