Description
Technical field
The present invention relates to the synthetic leather field, be specifically related to a kind of slurry, its preparation method of aqueous polyurethane of alternative wet production use for synthetic leather and utilize the preparation method and the resulting synthetic leather bass product of the slurry wet production synthetic leather of aqueous polyurethane of the present invention.
Background technology
The PU synthetic leather results from 20th century late nineteen seventies, develops in the nineties in 20th century.During traditional PU synthetic leather was produced, the PU resin that all adopts organic solvent was as basic unit and the surface layer of producing the leather product, and such PU resin is all with toluene, dimethylbenzene, acetone, butanone (MEK), acetate
Ethyl ester and dimethyl formamide (DMF) etc. make by polymerization as primary solvent.These solvents, toxic side effect is big, not only causes environmental pollution, and direct labor's health is caused huge injury, endanger healthy, and inflammable and explosive, very easily industrial accident such as initiation fire.It is reported, developed country alleviates the pollution of wet method PU chemical leather production to environment, carried out and used of the research of polyurethane leather use resin as substitute, PU makes and develops towards PU dispersion liquid, PU water miscible liquid direction, product applications is constantly widened, and develops into other special application fields such as clothes, ball, decoration with, case and bag field from the footwear of beginning.Therefore, exploitation Wet-type polyurethane leather use production of resins technology not only can solve environmental pollution, and helps the variation of product, and market outlook are very good.
The synthetic leather that uses waterborne polyurethane resin to make not only has the emulation skin and the air permeability and good of height, aqueous polyurethane with the leather base fabric course of processing in can form surfacing, the uniform wet method layer of abscess, and the universal performance requirement of tool synthetic leather, and can avoid the use of solvent, in process of manufacture, there is not the toxic and harmful discharging, realize cleaner production and safety in production, reach the nontoxic full feature of environmental protection and high physical and chemical performance, its social benefit and economic benefit are very remarkable.
Summary of the invention
The object of the present invention is to provide that a kind of cost is low, effective, safety and environmental protection, the slurry of the aqueous polyurethane that the alternative wet-method synthetic leather that has no side effect is used, and the preparation method of this slurry is provided.Another object of the present invention provides a kind of simple and reliable, there is not the toxic and harmful discharging in the process of manufacture, cleaner production and safety in production be can realize, and the preparation method of aqueous polyurethane slurry of alternative wet-method synthetic leather of the present invention and the synthetic leather bass product that obtains utilized.
Bass is the transliteration of English BASS, and its connotation is the meaning of base material (work in-process leather), and bass after technologies such as ornamenting such as surface printing, embossing, mill skin, just can become final synthetic leather finished product through dry method veneer or surface.
Main technical schemes of the present invention is:
The slurry of aqueous polyurethane is characterized in that comprising the component of following weight proportion: 80～130 parts of aqueous polyurethanes; 5～10 parts of suds-stabilizing agents; 0.1～0.6 part of linking agent; 5～10 parts of kaolin; 3～8 parts of pulp powders; 2～5 parts of thickening materials.
Aqueous polyurethane of the present invention adopts and contains two keys, the good aliphatic polyurethane of snappiness and/or aromatic urethane in the molecule, and described aliphatic polyurethane is non-xanthochromia prepolymer.Described aromatic urethane is not anti-xanthochromia.Two classes all can be used for preparing slurry.Two classes both can be used alone, but also also mix together.Can select dissimilar urethane according to the requirement of product; Preferred version is to use separately, and its reason is: mixing the result who uses and being not only increases cost but also anti-xanthochromia effect is reduced even to not having.
The preparation method of the slurry of above-mentioned aqueous polyurethane, it is characterized in that: in container, add aqueous polyurethane and continuously stirring, add kaolin, pulp powder more successively, high-speed stirring 10～30 minutes, kaolin and pulp powder are well-dispersed in the aqueous polyurethane, then add suds-stabilizing agent, surely steeped 10～45 minutes, add linking agent then and stir, add the viscosity that thickening material is adjusted to needs again.
The agitator of described stirring is the stainless steel metal agitator, and described being stirred under normal temperature, the normal pressure carried out.
Described container is the stainless steel cask after plastics or the polishing.
Utilize the preparation method of the slurry production synthetic leather bass of above-mentioned aqueous polyurethane, it is characterized in that may further comprise the steps:
(1) the certain density base cloth treatment agent of preparation; Described base cloth treatment agent is made up of peptizer and deionized water, and its weight proportion is: 0.5～3 part in peptizer, 80～200 parts of deionized waters;
(2) with base cloth in the base cloth treatment agent fully wetting after, press dry, in 60 ℃～130 ℃ baking oven, dry again;
(3) base cloth is put in waits on the coating machine to be coated with;
(4) with the prepared slurry blade coating on above-mentioned base cloth; The preparation method of described slurry is: add aqueous polyurethane and continuously stirring in container, add kaolin, pulp powder more successively, high-speed stirring 10～30 minutes, kaolin and pulp powder are well-dispersed in the aqueous polyurethane, then add suds-stabilizing agent, steady bubble 10～45 minutes adds linking agent then and stirs, and adds the viscosity that thickening material is adjusted to needs again;
(5) base cloth that will scribble slurry is dried in 80 ℃～140 ℃ baking oven, obtains work in-process;
(6) with the work in-process process washing again that obtains, wash the base cloth treatment agent off, obtain the synthetic leather finished product.
The synthetic leather bass that the preparation method who utilizes the aqueous polyurethane slurry to produce synthetic leather makes.
The cost of sizing agent of aqueous polyurethane of the present invention is low, effective, safety and environmental protection, have no side effect, the preparation method that the slurry that utilizes aqueous polyurethane of the present invention is produced the synthetic leather bass is simple and reliable, no toxic and harmful discharging in the process of manufacture, can realize cleaner production and safety in production, the synthetic leather product that makes not only has the emulation skin and the air permeability and good of height, nontoxicity and noresidue smell, meet the relevant national standards regulation fully, and its production cost is low, have the stronger market competitiveness, its social benefit and economic benefit are very remarkable.
