Abstract
The invention relates to a method for producing polyurethane synthetic leather with skin-imitated effect, which comprises the following specific steps of: coating a polyurethane coating on raising base cloth to form a wet semi-finished product; performing high-solid printing on the wet semi-finished product with a finishing agent; coating velvet crazy horse slurry after the high-solid printing; and putting the semi-finished product into a rubbing barrel, and introducing steam to perform dry rubbing to obtain the polyurethane synthetic leather. The polyurethane synthetic leather prepared by the method has soft and allochroic skin-imitated effect.
Description
Technical field
The present invention relates to the production method of Synthetic Leather, the production method of a kind of imitative head layer frosted bark effect Synthetic Leather of more specifically saying so.
Background technology
Synthetic Leather is called for short the PU synthetic leather, be a kind of with various fabricbases as base material, the coated with polyurethane resin makes it give the real leather intimating synthetic leather of various decorative patterns, pattern, function and feel on base material.Traditional P U synthetic leather Boardy Feeling and sense of fullness are poor, and the plastic cement sense is strong, and surperficial airtight to wear comfort sense poor, and the velvet of corium is not strong.
Summary of the invention
The present invention be directed to PU synthetic leather surface velvet effect and durability a kind of production method of real leather intimating polyurethane synthetic leather is provided.
The production method of real leather intimating polyurethane synthetic leather of the present invention is to operate as follows:
A kind of production method of real leather intimating polyurethane synthetic leather is characterized in that: operation as follows:
A, the coated with polyurethane coating is processed wet half-finished product on raising base cloth; Said coated with polyurethane coating proportioning raw materials by weight is:
The polyester polyethers gathers 100 parts of carbon copolymer resins SW-5215
Dimethyl formamide DMF 60-140 part
Solvent borne colorant 0-5 part
Lignocellulose 0-5 part
Anion surfactant B-90 0.5-2 part
Non-ionic surface active agent S-91 0.5-2 part
B, the wet half-finished product that a is made are carried out the solid stamp of height with finishing agent and are handled; Described finishing agent proportioning raw materials by weight is:
100 parts of high solids content 50% table place agent UA-1421
40 parts of butanone
C, have on the wet half-finished product of three-dimensional pattern effect on the surface that step b makes, contrary roller coat covers the polyurethane resin with color changeable effect; Described crazy horse skin slurry proportioning raw materials by weight is:
100 parts of BLPU-7853
60 parts of MEK
Organic toner 3-5 part
D, with the contrary roller coat of 240 order sand paper grindings adorn to pass through the crazy cordovan that makes after the c step surperficial, grind the velvet effect;
E, the leather of getting well mill are at last put into rub barrel, feed steam and carry out dry rub.
Beneficial effect of the present invention is embodied in:
1, adopts the polyester polyethers to gather carbon copolymerization polyurethane resin in the polyurethane coating of the present invention and solved then not weather-proof, the weather-proof then not soft technical problem of traditional P U slurry softness.
2, surperficial velvet has slight color changeable effect by force, and indistinct decorative pattern is arranged, and the fold exquisiteness exactly likes corium.
The specific embodiment
Below, the present invention is done explanation in further detail through specific embodiment.
Synthesizing of a kind of real leather intimating polyurethane synthetic leather.
1) selects grammes per square metre 220g/m
2About, thickness 0.8mm, fluffing is even, and thickness is even, the two-sided nylon loop that the Fu Jiannan of fabric width 1.45M spins, the coated with polyurethane coating is processed wet half-finished product on raising base cloth;
2) select the polyester polyethers to gather carbon copolymer resins SW-5215 and carry out the synthetic of wet method fabricbase, concrete prescription is:
The polyester polyethers gathers 100 parts of carbon copolymer resins SW-5215
Dimethyl formamide DMF 60-140 part
Solvent borne colorant 0-5 part
Lignocellulose 0-5 part
Anion surfactant B-90 0.5-2 part
Non-ionic surface active agent S-91 0.5-2 part
3) decorative pattern of the high solid material of printing is on the wet method fabricbase, and related equipment has three printing machines, and height prints wheel admittedly;
Described finishing agent proportioning raw materials by weight is:
100 parts of high solids content 50% table place agent UA-1421
40 parts of butanone
4) on the wet half-finished product that step 3) makes, utilize contrary roller coating machine to apply the crazy horse skin slurry of velvet, to obtain the effect and the various colors of velvet; Described crazy horse skin slurry proportioning raw materials by weight is:
100 parts of BLPU-7853
60 parts of MEK
Organic toner 3-5 part
5) with 240 order sand paper grinding skins, enhanced surface velvet effect, device therefor is a decorticating mill;
6) Synthetic Leather that step 5) is made is put into rub barrel, feeds steam and carries out dry rub, and further enhanced surface velvet effect obtains the Synthetic Leather with leather effect of soft variable color.
Annotate: high solids content 50% table place agent UA-1421 is the rich holy Company products in Guangzhou, is characterized in that the high printed pattern third dimension of solid content is strong; Anion surfactant B-90, non-ionic surface active agent S-91 are Hebei San He Company products, and main effect is to improve the wetting property of wet polyurethane slurry on base cloth; Organic toner adopts the faeces Company products, and the good colour saturation of this product transparency is high; SW-5215 is that the polyester polyethers that Hefei Amway polyurethane new material Co., Ltd produces gathers the carbon copolymer resins; BLPU-7853 is soft, the crazy-horse resin that velvet is strong that Hangzhou dark blue chemical industry Co., Ltd produces.
