Abstract
The invention discloses a starch and ethylene-vinyl acetate composite foaming agent shoe sole material. The material is prepared from, by weight, 100 parts of ethylene-vinyl acetate, 30-50 parts of modified starch, 10-30 parts of polyimide resin, 10-30 parts of ethylene-acrylic acid copolymer, 0-10 parts of graphene fiber, 0-30 parts of inorganic filler and 4-12 parts of a glycerin plasticizing agent; a preparation method of the modified starch comprises the following steps that the starch is dissolved in water, heated to 85 DEG C to 95 DEG C, gelatinated for 20 min to 40 min and then cooled to 60 DEG C or below, an ammonium persulfate initiator and a vinyl acetate monomer are added in sequence, reacting is conducted for1 h to 5 h under the temperature of 60 DEG C to 80 DEG C, absolute ethyl alcohol is added for precipitation, filtering and drying are conducted in sequence, and graft modified starch is obtained. According to the shoe sole material, after the material is prepared into a shoe sole, the minimum density of the material is 0.085 g/cm<3>, even graphene fiber is not used, the tensile strength reaches 25 kg/cm<2>, the rebound resilience exceeds 54%, and the tear strength exceeds 29 kg/cm.
Description
Technical field
The present invention relates to material for sole of shoe technical field, more particularly, to a kind of starch ethylene-vinyl acetate composite foamable agent
Material for sole of shoe.
Background technology
The construction of sole is considerably complicated, just in the broadest sense, it may include the material of all composition bottoms such as outer bottom, middle bottom and heel
Material.For narrow sense, then for only referring to outer bottom, the common characteristic of general material for sole of shoe should possess wear-resisting, water-fast, oil resistant, heat-resisting,
Pressure, impact resistance, elasticity is good, be easily suitable for foot type, not flexible type, insulation, easily absorption dampness etc. after sizing, more will coordinate simultaneously
Middle bottom, the terms and conditions such as have braking action to be not to slip and be easy to stop in the change of feet on foot.The species of sole materials is a lot,
Natural class bed material and two kinds of class bed material of synthesis can be divided into.Natural class bed material includes natural bottom leather, bamboo and wood material etc., synthesizes class bed material
Including rubber, plastics, rubber and plastic suitable materials, regenerated leather, elastic hardboard etc..
Content of the invention
It is an object of the invention to proposing a kind of starch ethylene-vinyl acetate composite foamable agent material for sole of shoe, Neng Gouti
The performance of high material for sole of shoe.
For reaching this purpose, the present invention employs the following technical solutions:
A kind of starch ethylene-vinyl acetate composite foamable agent material for sole of shoe, includes by weight
Ethylene-vinyl acetate 100
Modified starch 30-50
Polyimide resin 10-30
Ethylene-acrylic acid copolymer 10-30
Graphene fiber 0-10
Inorganic filler 0-30
Glycerol plasticizer 4-12.
The preparation method of modified starch of the present invention is as follows:
Starch is soluble in water, it is heated to 85-95 DEG C, gelatinizing 20-40min, then it is cooled to less than 60 DEG C, add over cure
Sour ammonium initiator, adds reaction 1-5 hour at Vinyl Acetate Monomer, 60-80 DEG C, adds dehydrated alcohol precipitating, filter, dry
Dry obtain graft modified starch.
The present invention falls original ethylene-vinyl acetate using modified starch partial replacement, because graft modified starch changes
It has been apt to the compatibility of starch and vinyl-acrylate copolymer, when being not in that starch is mixed with vinyl-acrylate copolymer
The phenomenon of phase separation occurring, improves the performance of material for sole of shoe.
Because modified starch overcomes the defect of starch, the graphene fiber therefore working in coordination with use with starch can omit.
But after addition graphene fiber, it remains able to increase tensile strength and tearing strength.
Material for sole of shoe of the present invention, after being prepared into sole, the minimum 0.085g/cm of its density3Even if not making
With graphene fiber, its tensile strength reaches 25kg/cm2, more than 54%, tearing strength is more than 29kg/cm for resilience.
