Description

A kind of high hydrolysis resistance and high ultraviolet resistance illumination aging are from the system of decontamination Synthetic Leather Make method
Technical field
The present invention relates to synthetic leather field, be specifically related to a kind of high hydrolysis resistance and high ultraviolet resistance illumination aging from the poly-ammonia of decontamination The manufacture method of Lipase absobed leather.
Background technology
Polyurethane (PU) is the abbreviation of polyurethanes, and polyurethane is a kind of emerging high-molecular organic material, is praised For " the fifth-largest plastics ", it has the characteristics such as good optical property, thermostability, wearability and mechanical performance Modulatory character, can It is widely used in the materials such as making synthetic leather, coating, insulating foam and TPU.
Synthetic leather is the material replacing natural leather article ideal the most in the world, is mainly used in footwear, case and bag The fields such as bag, ball, furniture and automobile.Along with the raising of living standards of the people, the ruggedness aspect of synthetic leather is also carried by people Gone out higher requirement, particularly in terms of some public places and decorative engineering, the performance of common Synthetic Leather without Method meets requirement.
Common Synthetic Leather is primarily present shortcoming the most aging under steam, air and ultraviolet lighting environment, poly-ammonia The structure of Lipase absobed leather porous has stronger characterization of adsorption, has adsorbed the hydrone in air and oxygen molecule, has caused polyurethane The hydrolysis ageing properties of synthetic leather is poor, at present, mainly improves its hydrolysis ageing properties by two ways, outside one is Interpolation perfluoro organic compound, in coating paste, makes coating have certain water repellent ability, delays coating to a certain extent Hydrolysising aging, but be the failure to fundamentally improve；Two is by repairing the hydrolysising aging sensitive group (such as ester bond) of polyurethane Or use the preferable polyethers of hydrolysis property or polycarbonate polyurethane, but, although it is water-fast that these means solve synthetic leather Solution problem, but also occur in that cold-resistant, folding and the best problem of ultraviolet resistance illumination aging performance.At present, Synthetic Leather There is ultraviolet light and irradiate the situation that lower yellowing is even ftractureed, be mainly used in coating paste additional ultraviolet absorber etc. and improve, Problems cannot be inherently eliminated.
The present invention is by carrying out fluorinated modified to polyurethane resin, under dry process, utilizes modified fluorine-containing poly-carbon type to gather The surface layer of urethane resin and modified fluorine-containing poly-carbon type polyurethane resin adhesive linkage slurry carry out veneer to fabricbase, and ripening prepares produces Product, after testing, at a temperature of 70 DEG C, under 95% relative humidity, place 11 weeks leather surfaces without ftractureing without powder phenomenon-tion；Ultraviolet resistance shines Burn-in test, method is AATCC16 Option after 3,200 hours, and leather surface is without cracking without powder phenomenon-tion, and sample grade reaches 6 More than Ji.Detect its dirt-removing power by AATCC 130 and reach more than 3 grades.
Summary of the invention
It is an object of the invention to provide a kind of high hydrolysis resistance and high ultraviolet resistance illumination aging from decontamination Synthetic Leather Production method, the hydrolysis that technical problem is that Synthetic Leather to be solved and ultraviolet resistance illumination aging performance, 70 At a temperature of DEG C, under 95% relative humidity, place 11 weeks leather surfaces without ftractureing without powder phenomenon-tion；Ultraviolet resistance illumination aging is tested, method For AATCC 16 Option 3, exposure time is after 200 hours, leather surface without cracking without powder phenomenon-tion, sample grade reach 6 grades with On.Detect its dirt-removing power by AATCC 130 and reach more than 3 grades.
