Abstract

The invention discloses a new cork mid-sole which is environment-friendly and healthy. The new composite cork mid-sole can be obtained by mixing natural latex, natural cork and natural bamboo-carbon. The new composite cork mid-sole can be used for a long time at temperature from minus 20 DEG C to 60 DEG C and can balance the body and realize that the user can walk for a long time without ache on both the legs and the feet. The new cork mid-sole can give a full play to the force bearing area and the balance capacity of a people during walking and standing, and is comfortable to wear and has the obvious effect of preventing lesion. The new cork mid-sole is suitable for various of shoes.

Description

The end in the cork

[technical field]

The present invention relates to the material for sole of shoe field, more particularly relate to the compound middle bottom material of a kind of natural cork.

[background technology]

Along with the raising of people's living standard, there has been leap to a great extent the clothing ,food and housing provisional capital, and no longer is merely to be satisfied with basic life.Footwear also begin to have injected new notions such as health, environmental protection, leisure, fashion.Existing material for sole of shoe mainly is rubber, plastics, rubber polymer etc.Because these materials mostly are not natural, environment is polluted easily, even may cause disease of skin, the comfort that wears is relatively poor.

[summary of the invention]

On the one hand, the objective of the invention is to overcome the shortcoming of prior art, from human foot engineering science and the common pathology of foot, provide a kind of novel cork compound in the end, characteristics such as it has health, environmental protection, comfortable, nontoxic, light weight, high resilience, damping, anti-ly damages by worms, ageing-resistant, moisture absorption, deodorization.

On the other hand, the present invention also provides a kind of technology of making the end in the above-mentioned cork.

Above-mentioned two purposes of the present invention realize by following technical scheme.

The modern society people design the shoes of any style, any materials for attractive in appearance, fashion, follow, put down shoes such as hard as tip, height, constantly injure people's both feet.Health for people, the inventor does not wear the theory that shoes step down in life on the soft ground, keep total balance of the body according to the mankind of primitive society, pin shape in conjunction with modern people is evolved, modern people's sole is stepped down in soft terrain and when walking to be kept total balance of the body and designs, has the human body of making when walking for a long time and standing, characteristics such as leg is not sour, pin is painful.

The inventor creatively finds, Heveatex and natural cork, natural bamboo carbon are mixed, and just can realize the pluses and minuses complementation, and it is comfortable not only to wear, and can also keep total balance of the body for a long time.Long-time walking has the advantages that leg is not sour, pin is not painful, and is comfortable and easy to wear in addition, and prevention sole pathology etc. has obvious effect.

The material of making the end in the cork of the present invention comprises Heveatex, natural cork, natural bamboo carbon, sulphur, promoter (BZ, PX etc.), age resistor, colouring agent, gunny cloth, natural ox-hide or artificial leather.

Natural cork is taken from softwood trees and is had another name called " cork oak ", is the surface texture behind the stem root growth of bolt tree.Bolt tree will grow that 20-25 could shell for the first time skin, not only to have shelled skin not dead, and the longer the better, could shell once every 8-9 after the peeling again, removes surperficial casting skin through processing and just can use.Cork has the special cells structure, make cork have low-density, compressibility, good springiness, waterproof, thermal conductivity factor is low, adiabatic, absorbing, sound absorption, excellent properties such as wear-resisting, is the ideal material of making sole.

It is raw material that gunny cloth adopts the high-quality sisal hemp leaf, sisal hemp has another name called sisal, sisal hemp leaf includes abundant fiber, fibrocyte is elongate structure, lumen big and grow, wall thickness, have that fiber is long, color and luster is pure white, strong but pliable in texture, high resilience, strong, the wear-resisting wiping of pulling force, acid and alkali-resistance, corrosion-resistant, the characteristics that are difficult for skidding.Dye again and be woven into gunny cloth again through being processed into the rope made of hemp.Gunny cloth has good, superpower ventilative, the heat radiation clearing damp of quality softness, wrinkle resistance, it is very refreshing to dangle, antibiotic health care is splendid green health lining.

Colouring agent is meant and comprises pigment and dyestuff by the colorful materials of article such as can making plastics, rubber, coating.Can freely select according to producing needs.

Bamboo carbon be bamboo wood under the condition of high temperature, anoxic (or restrictive aerating oxygen), make the bamboo wood decomposes and the solid matter that obtains.Usually can produce 1 ton of bamboo carbon with the fresh bamboo wood of 6-6.5 ton, a production cycle is about 6-20 days.Available data shows that bamboo carbon has far infrared and anion, can regulate function such as do wet, insulation, antibacterial, deodorization deodorizing, stimulate circulation.

The preparation method at the end is as follows in the cork of the present invention:

1. sulphur, promoter (BZ, PX etc.), colouring agent are processed into aqueous dispersion separately;

2. vulcanized latex, 60 parts of Heveatexes, sulphur 1.8-5 part, promoter 0.75-3 part, zinc oxide 1.3-3 part, antioxidant SP 1.5-2.1 part, colouring agent suitably adds as required, mixes with dispersion machine to stir; More than be meant and do than prescription;

3. cooperate step 2 uniform Heveatex and cork to be stirred in together again, making a gesture of measuring of the two can be adjusted voluntarily according to the needs of gel content, is controlled at 2 usually: 3-3: within 2 scopes;

4. the latex cork that mixes is poured into mould one-shot forming sulfuration in pass in the mould of putting gunny cloth well, conditions of vulcanization 70-110 ℃, time 2-3 minute, can suitably adjust as required;

5. the dry processing of the cork sole of the demoulding.Can use heat drying, also can air drying, it is consistent with the secondary mould to be dried to size.

6. putting into the post forming mould at the bottom of the good cork of drying; gunny cloth is crossed an amount of Heveatex; be placed on and put one deck bamboo carbon (consumption of bamboo carbon can suitably be adjusted as required) on the cork sole again; put natural ox-hide of one deck or artificial leather (also can under gunny cloth, add one deck EVA) again; close the mould post forming; temperature 80-120 ℃, time 2-3 minute, the demoulding, drying, deburring, check, stopping off, packing.

[specific embodiment]

Embodiment 1

At first with sulphur, accelerant B Z, zinc oxide is processed into 50% aqueous dispersion separately, and colouring agent is processed into 20% aqueous dispersion.Vulcanized latex (doing than prescription) is by following proportioning, and Heveatex 60 restrains, sulphur 5 grams, and promoter 3 grams, zinc oxide 3 grams, antioxidant SP 1.5 grams, colouring agent adds as required, lumps together with the dispersion machine branch to stir.Again Heveatex that stirs and cork (the two dried proportioning is 1: 1) are mixed.The latex that stirs, cork are poured into one-shot forming in the mould of putting gunny cloth well, and Guan Mo vulcanized 3 minutes down at 110 ℃.It is consistent with the secondary mould that size is handled in the demoulding, heat drying.Putting into the post forming mould at the bottom of the good cork of drying; gunny cloth is crossed a certain amount of Heveatex; be placed on the cork sole; put one deck bamboo carbon on the burlap, put natural ox-hide of one deck or artificial leather again, can under burlap, put one deck EVA or Heveatex sheet more for more comfortable; close the mould post forming; 120 ℃ of temperature, 3 minutes time, the demoulding, drying, deburring, check, stopping off, packing.

After testing, mass parameter is as follows:
