For realizing above-mentioned technical purpose; Reach above-mentioned technique effect; The present invention realizes through following technical scheme: a kind of footwear material surface treatment method, the footwear material is placed in the vacuum chamber, and vacuum is 0.01-2000Pa in the said vacuum; The temperature on said footwear material surface is 30-200 ℃, under the working gas environment, said footwear material is carried out discharge of plasma in low temperature and handles.
Preferably, at first, it is 0.01-2000Pa that the vacuum in the said vacuum chamber is extracted into vacuum; Then, the surface temperature with said footwear material is heated to 30-200 ℃; At last, feeding said working gas makes said working gas carry out the discharge of plasma in low temperature processing to said footwear material.
Preferably, at first, the surface temperature of said footwear material is heated to 30-200 ℃; Then, the vacuum in the said vacuum chamber being extracted into vacuum is 0.01-2000Pa; At last, feeding said working gas makes said working gas carry out the discharge of plasma in low temperature processing to said footwear material.
Preferably, said working gas is an air.
Further, the material of said footwear material is any one or the multiple combination in EVA (ethylene-vinyl acetate copolymer), PU (polyurethanes), TPU (rubber), PVC (polyvinyl chloride), skin, leather or the cloth.
Compared with prior art, the present invention has following beneficial effect:
The present invention makes footwear material surface produce active group, with the processing water treatment technology that replaces adopting at present, improves the adhesive strength of footwear material and adhesive.
The present invention adopts Low Temperature Plasma Treating technical finesse footwear material surface energy-conservation and environmental protection; Utilize the Low Temperature Plasma Treating technology to carry out the bonding preceding preliminary treatment on footwear material surface; Not only can solve present use and handle shortcomings such as the pollution of water existence, power consumption, and, can also practice thrift cost for the user because low temperature plasma process for treating surface operating cost is low; Can also be reduced to simultaneously the hazard residue thing content of footwear, improve into the footwear quality; Improve shoemaking Production Line environment, promote the healthy of worker.
The present invention makes the adhesive strength of the footwear material after the processing meet or exceed the intensity of treated water treatment, thereby replaces the poisonous footwear material surface treatment water treatment technology that pollution is arranged always continued to use for many years.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention specify as after.
