Description
Technical field：
The present invention relates to Synthetic Leather technical fields, and in particular to a kind of aqueous table of brightening type Synthetic Leather
Face finishing agent.
Background technology：
Brightening type leather finishing agent is common a kind of finishing agent in synthetic leather production, can assign the outer of synthetic leather light
It sees, while can also assign and synthesize certain feel.Existing brightening type leather finishing agent mostly uses greatly solvent type polyurethane resin,
Various auxiliary agents are added after diluting by solvent to be prepared, are coated on synthetic leather surface when in use, then heating makes solvent wave
Hair forms polyurethane coatings on synthetic leather surface.
Since solvent type polyurethane resin needs organic solvent diluting, it can volatilize because of solvent cause ring in use
Border is polluted, and the requirement currently to environmental protection is not met, and people put forth effort on exploitation aqueous polyurethane leather treatment in recent years thus.Water
Property polyurethane leather inorganic agent use aqueous polyurethane for main carriers, do not use or using only minimal amount of hypotoxicity it is organic molten
Agent not can cause environmental pollution.
Solvent borne polyurethane is different from the membrane formation mechanism of aqueous polyurethane, and solvent borne polyurethane finishing agent film forming is uniform
Polyurethane film seems that plastic sense is strong, not enough naturally when glossiness is higher.Waterborne polyurethane coating agent is lotion, and film forming is breast
Micelle diameter stacks, and the inhomogeneities formed with the fibre structure of corium has similarity, therefore gloss, feel be all after forming a film
Seem more naturally, closer to corium.
Invention content：
Gloss and the natural light of feel after strong, film forming that technical problem to be solved by the present invention lies in a kind of feature of environmental protection of offer
Bright type polyurethane use for synthetic leather aqueous surface finishing agent.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of brightening type Synthetic Leather aqueous surface finishing agent, is mixed by the raw material of following parts by weight：
100-150 parts of aqueous polyurethane emulsion, 1-5 parts of amide hydrogenation castor oil, has 1-5 parts of polyurethane associative thickener
0.5-3 parts of machine silicon hand feeling agent；
The preparation process of the aqueous polyurethane emulsion is：First by 60g polybutylene glyool adipates, 3g terminal hydroxy group sulphurs
Hydrochlorate polyester, 6g ethohexadiols, 3g polycaprolactones trihydroxylic alcohol, 3g 2,2- dihydromethyl propionic acids be added reaction kettle in, in 0.05MPa,
107 DEG C vacuumize 1h and remove moisture removal, remove vacuum, are passed through nitrogen, and 25g isophorone diisocyanates are slowly added dropwise at 65 DEG C
Ester keeps the temperature 1h after dripping off, and adds 0.05g stannous octoates, is warming up to 75 DEG C of insulation reactions, and detection isocyanate content≤
Stop heating when 0.1wt%, adjusts viscosity with acetone after being cooled to 50 DEG C, be used in combination dimethylethanolamine to be neutralized to 7-8, finally exist
60g deionized waters are added under 45 DEG C of high-speed stirreds and disperse 30min, removed under reduced pressure acetone is to get aqueous polyurethane emulsion.
The polybutylene glyool adipate molecular weight 1000.
The polycaprolactone trihydroxylic alcohol molecular weight 500.
The amide hydrogenation castor oil is made of rilanit special modification, and preparation method is：By rilanit special and fourth
It is heated to 95~105 DEG C of insulated and stirred reactions after dicarboxylic anhydride mixing, asparatate is added after acidification reaction, continues to heat
Reacted to 135~145 DEG C of insulated and stirreds, 0.1MPa be evacuated to after amidation process and keeps 30min, remove after vacuum from
It is so cooled to room temperature, micro mist is made to get amide hydrogenation castor oil through micronizer in obtained solid.
The rilanit special, succinic anhydride, asparatate mass ratio be 20-40:5-10:5-10.
Rilanit special is reacted with succinic anhydride to introduce carboxyl on rilanit special, and carboxyl is generated with primary amine reaction again
Amide.
The beneficial effects of the invention are as follows：The present invention is assisted using aqueous polyurethane emulsion as major ingredient with polyurethane associative thickening
Brightening type Synthetic Leather aqueous surface finishing agent, the covering with paint is made in agent, amide hydrogenation castor oil and organic silicon hand feeling agent
Organic solvent is not added in agent, using water as diluent, substantially increases the use feature of environmental protection of finishing agent；And made finishing agent
Use can improve the glossiness of synthetic leather, while gloss is naturally, will not seem that plastic sense is strong；In addition, made finishing agent makes
With the resistance to heat-blocking that can enhance synthetic leather, solve the problems, such as that anti-adhesion performance is poor under high temperature.
