Abstract
The invention discloses a production method of no-yellowing composite leather, which is implemented by following scheme: preparing no-yellowing resin, DMF, MEK, TOL, antioxidant and pigment into plus materials; preparing hydrolysis resistant substrate, DMF, MEK, TOL, antioxidant and pigment into a substrate; selecting proper base materials; preparing the plus material, substrate and base material at a temperature of 160 +-20 DEG according to common dry coating method to obtain composite containing the plus material layer, substrate layer and base material layer; external surface of the plus material layer of the composite leather is printed with NOX resistant auxiliaries, then proceeding NOX resistant treatment to obtain no-yellowing composite leather of the invention. The invention proceeds uvioresistant treatment to the no-yellowing resin in the plus material and the substrate, adding anti-oxidation additives in the plus material and the substrate to reduce dosage of TOL and MEK which are easily discolored in air by oxidation, and increas dosage of DMF to improve antioxygenic property of composite leather; improving temperature of oven in process of producing leather by dry coating method, solvent is volatilized completely, yellowing caused by solvent is avoided; adding a printing process to proceed NOX resistant treatment on surface of the composite leather, which can avoid yellowing caused by NOX oxidation in air effectively.
Description
Technical field
The present invention relates to the process hides field, specifically is a kind of production method of no-yellowing composite leather.
Background technology
General white or light synthetic leather product can produce xanthochromia in sunshine, air, can not keep primary colors, and NOX (oxynitrides) oxidation causes in irradiation and the air of UV sunlight because the synthetic leather product receives.The yellowing resistance of synthetic leather can be a technical problem of puzzlement industry all the time.
Existing production method of no-yellowing composite leather generally comprises following steps:
1, gets the raw materials ready: be made into lining with the not yellowing resin of 100 weight portions, the DMF (dimethyl formamide) of 30 weight portions, the MEK (butanone) of 10 weight portions, the TOL (toluene) and an amount of colorant of 5 weight portions; Be made into bed material with the hydrolysis bed material of 100 weight portions, the DMF of 25 weight portions, the MEK of 15 weight portions, the TOL of 10 weight portions and an amount of colorant; Select suitable substrates for use;
2, dry coating: according to the dry coating method of routine; Lining is coated with scrapes on release liners surface; Then be in the same place base material and the release liners that scribbles lining through bed material; Through after the baking oven for heating to 130 ℃ release liners and finished product synthetic leather are peeled away, just obtained having surface layer, the finished product synthetic leather of bottom and substrate layer;
Existing this production method of no-yellowing composite leather, the anti-xanthochromia of synthetic leather are handled and mainly are to use not yellowing resin to carry out anti-ultraviolet radiation treatment, and synthetic leather does not possess anti-NOX performance, and antioxidant effect is relatively poor, still can produce xanthochromia; And solvent evaporates can not get effective processing in producing, solvent remain in the xanthochromia that also can influence synthetic leather to a certain extent.
Summary of the invention
The purpose of this invention is to provide a kind of production method of no-yellowing composite leather, the no-yellowing composite leather that makes through the inventive method can really reach the not effect of xanthochromia.
Technical scheme of the present invention is such: production method of no-yellowing composite leather, realize through following steps:
A, get the raw materials ready: be made into lining with the not yellowing resin of 100 weight portions, the DMF (dimethyl formamide) of 40 ± 5 weight portions, the MEK (butanone) of 5 ± 2 weight portions, the TOL (toluene) of 5 ± 2 weight portions, the anti-oxidant auxiliary agent of 3 ± 1 weight portions and an amount of colorant; Be made into bed material with the hydrolysis bed material of 100 weight portions, the DMF of 30 ± 3 weight portions, the MEK of 10 ± 2 weight portions, the TOL of 5 ± 2 weight portions, the anti-oxidant auxiliary agent of 3 ± 1 weight portions and an amount of colorant; Select suitable substrates for use;
B, dry coating: according to the dry coating method of routine; Lining is coated with scrapes on release liners surface; Then be in the same place base material and the release liners that scribbles lining through bed material; Through behind baking oven for heating to 160 ± 20 ℃ release liners and finished product synthetic leather are peeled away, just obtained having surface layer, the synthetic leather of bottom and substrate layer;
C, printing treatment: on the outer surface of the surface layer of the synthetic leather of step B oven dry, being printed with the auxiliary agent of anti-NOX, carry out anti-NOX PROCESS FOR TREATMENT, just obtain no-yellowing composite leather of the present invention.
Above-mentioned anti-oxidant auxiliary agent is the age resistor that contains anilino-.
The main component of the above-mentioned auxiliary agent of anti-NOX is acid (NN-2 methyl-prop phosphinylidyne-four-aminophenyl) methane.
After adopting such scheme; Production method of no-yellowing composite leather of the present invention; Not yellowing resin through in lining and bed material is carried out anti-ultraviolet radiation treatment, in the lining of synthetic leather and bed material, increases anti-oxidant auxiliary agent, reduces that oxidation causes the TOL of variable color and the consumption of MEK in air than being easier to; Increase the consumption of DMF, thereby improve the antioxygenic property of synthetic leather; In the process of dry coating method process hides, improve temperature of oven, let solvent fully volatilize, avoided the xanthochromia that causes because of solvent; Increase the printing treatment operation, the auxiliary agent of anti-NOX is arranged, effectively avoided the xanthochromia that causes because of NOX oxidation in the air at the synthetic leather surface printing.Compared with prior art, the no-yellowing composite leather of producing through the inventive method is well improved in anti-solar ultraviolet, anti-NOX, performance such as anti-oxidant, is a kind of high performance synthetic leather product, and its each item performance indications are following:
A. uvioresistant: 4.5 grades of national standards, method of testing: use the special-purpose fluorescent tube irradiation of 30W*2 6HR test;
B. anti-NOX:4 level national standard, method of testing: test after using vehicle exhaust to spray 0.5HR;
C. anti-oxidant: 4 grades of national standards.
