Description
Technical field:
The present invention relates to a kind of footwear material, particularly relate to a kind of PU footwear material and manufacture method thereof of high folding.
Background technology:
PU and urethane, have good rebound resilience, comfortableness, is therefore widely used in daily life.PU realizes industrialization the sixties in 20th century in Europe as footwear material, and the seventies enters North America market, and the eighties is in global fast development.At present, in whole world shoe industry, PU footwear material can account for the ratio of about 8%.PU footwear material is microvoid structure, have that intensity is high, good springiness, dress light comfortable, oil resistant, chemically-resistant properties of sample are good, be easy to the advantages such as machine-shaping, but its folding quality is not satisfactory, easily phenomenon of rupture occurs after having grown duration of service.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of PU footwear material of high folding, and its folding quality is very good.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A PU footwear material for high folding, its weight part consists of:
Preferably, the number-average molecular weight of polyether glycol of the present invention is 1500 ~ 4500, and theoretical hydroxy functionality is 2 ~ 4, and hydroxyl value is 20 ~ 100.
Preferably, isocyanic ester of the present invention is 4,4 '-diphenylmethanediisocyanate, 2,4 '-diphenylmethanediisocyanate or 2,2 '-diphenylmethanediisocyanate.
Preferably, coupling agent of the present invention is vinyl trichloro silane coupling agent.
Preferably, catalyzer of the present invention is triethylenediamine, tetramethyl-Alkylenediamine or dimethylcyclohexylamine.
Preferably, oxidation inhibitor of the present invention is antioxidant 1010 or anti-oxidant DLTP.
Another technical problem that the present invention will solve is to provide the manufacture method of the PU footwear material of above-mentioned high folding.
For solving the problems of the technologies described above, technical scheme is:
A manufacture method for the PU footwear material of high folding, comprises the following steps:
(1) nano imvite and coupling agent are carried out stirring and refluxing, through washing with acetone, filtration, dry under vacuum condition, obtain modified nano montmorillonite after grinding;
(2) polyether glycol and isocyanic ester are toasted drying respectively, for subsequent use;
(3) modified nano montmorillonite obtained in other components in formula and step (1) is added the polyether glycol after oven dry, mix formation compound;
(4) by the compound that obtains in step (3) and the isocyanic ester mixing casting after drying, the PU footwear material of high folding is obtained.
Therefore compared with prior art, the present invention has following beneficial effect:
Montmorillonite layer is scattered in PU matrix with nanoscale and forms " nanometer " effect, play crosslinked action, after coupling agent modified nano imvite, each monomer of synthesis PU is polymerized between cheating engaging layer, montmorillonite layer spacing in matrix material is made to reach 5.19nm, significantly improve the tensile strength of PU footwear material, elongation at break, folding quality is very good.
