The veneer processing method may further comprise the steps:
Release liners is unreeled, carry out the coating processing first time according to the lining prescription; Oven dry for the first time; After supercooling through the second time coating handle; Carry out the oven dry second time; Qualified semi-finished product are unreeled, carry out veneer and fit; Oven dry for the third time; Rolling; The bundling of testing at last.
The dimethyl formyl is 20% in the aforesaid dimethyl formyl aqueous solution.
Aforesaid squezzing, wherein roll is 1 group, and pressure is 6 kilograms/square metre, scalds 8 on roller, and oily temperature is 120 ℃ in the roller.
Aforesaid washing is through the washing of 12 roads, and the dimethyl formyl content of the wherein last rinsing bowl of washing together is less than 0.5%.
The coating layer thickness that the aforesaid first time, coating was handled is 0.12mm, and bake out temperature is 120 ℃, and the layer thickness that the described second time, coating was handled is 0.15mm, and bake out temperature is 100 ℃.
The aforesaid temperature of oven dry for the third time is 120 ℃～140 ℃.
The present invention compared with prior art has following remarkable advantages and beneficial effect:
A kind of hydrolytic resistant leather of the present invention and manufacture method thereof, it is short service life to have overcome original synthetic leather material, the phenomenon that is easy to generate mouldy, premature aging and causes because of temperature difference problem ftractureing.Solve the problem of synthetic leather poor water resistance, be greatly improved the service life of this finished product, simultaneously, also solved synthetic leather mildew-resistant, deodorization, problem such as anti-aging, significantly reduced the cracking phenomena that causes because of the temperature difference.
Description of drawings
Fig. 1 is the manufacture method flow chart of hydrolytic resistant leather.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are illustrated:
A kind of hydrolytic resistant leather is made up of semi-finished product and veneer; Wherein said semi-finished product prescription is: 45.70% polyurethane resin, 43.42% dimethyl formamide, 9.14% pulp powder, 0.55% bleeding agent, 0.09% defoamer, 0.18% levelling agent, all the other are industrial stock white;
Described veneer prescription comprises: lining and bed material; Wherein said lining prescription is: 51.28% polyurethane resin, 41.02% butanone, all the other are industrial white tablets;
Described backing material formula is: 55.56% polyurethane resin, 38.90% butanone, all the other are industrial white tablets.
See also shown in Figure 1ly, be the flow chart of the manufacture method of hydrolytic resistant leather; As can be seen from the figure, processing method of the present invention mainly is divided into semi-finished product processing 1 and veneer processing method 2.
