Description
Technical field
The present invention relates to a kind of footwear materials and production technique, especially a kind of footwear mixing natural materials and formula and manufacture craft.
Background technology
EVA is a kind of more common middle bottom material, has good flexibility and elasticity, is widely used in the fields such as foaming shoe material, functional canopy film, packing film, hot melt adhesive, electric wire and toy.But in traditional footwear materials formula, the content of EVA has almost occupied 100% of unit formula, the year limit for length that the pure EVA material degradation of this footwear is required, probably needs time of more than ten years.For this reason, just need a kind of EVA mixing material of environmental protection more to replace the pure EVA material of original footwear, shorten degradation time.The EVA mixing material of this environmental protection more, thus can be to utilize some natural materialss natural and easy degraded to replace the use of part EVA in formula to reduce the content of EVA in formula.
Summary of the invention
The object of the invention is: for required year this deficiency of limit for length of degraded of the pure EVA material of existing footwear, provide a kind of footwear mixing natural materials and formula and manufacture craft of environmental protection more.
The present invention is achieved in that
The design parameter of footwear EVA mixing material is as follows: density 0.32～0.38gr/cm
3, hardness 42～48ShA, load-carrying>=290%, cracking resistance>=3.8kg/cm, wear-resisting≤295mm
3, extend>=138%, folding > 60,000 times.The formula of described footwear EVA mixing material is by weight calculating: EVA10 part-20 part, 30 parts-40 parts of polyoxyethylenes, 10 parts-15 parts of weighting agents, 30 parts-40 parts, natural particle, 0.5 part-5.5 parts of linking agents, 2.0 parts-3.0 parts, zinc oxide, 0.8 part-5.8 parts of whipping agents, 10 parts-20 parts of stearic acid; Wherein, in every hundred parts of natural particles, contain 40 parts～55 parts of plant amylums, 10～15 parts of glycerine, 35～45 parts of polyethylene.
Described weighting agent is that talcum powder, linking agent are bridging agent, and whipping agent is AC whipping agent.
Starch is W-Gum, sweet potato starch, wheat starch.Certainly can also adopt other plant starch.The manufacture craft of described footwear EVA mixing material, comprises the following steps:
Step 1) is poured EVA, polyoxyethylene, weighting agent, natural particle, zinc oxide, stearic acid in stirrer, to stir and heat into, first be heated to 90 ℃ and make above product fusing, temperature is increased to more than 110 ℃ more afterwards, then add bridging agent and whipping agent, again temperature is increased to more than 120 ℃, pours material into Banbury mixer;
Step 2) material is carried out in Banbury mixer to banburying, the banburying time is 9～12 minutes, and temperature is at 120～130 ℃;
Step 3) is poured the material after banburying in mill into, cools the temperature to 75～80 ℃, thins 2～4 times, makes the thickness of product at 0.5～0.7mm;
Step 4) is put into tablets press granulation by the sheet material of beginning to pratise out, and temperature is 75～80 degrees Celsius, and the time is 12～18 minutes;
Step 5): particle is put into foaming mould, foam 360～420 seconds, temperature is controlled at 170～180 ℃, forms product.
Compare with the pure EVA material of existing footwear, the present invention has the following advantages: 1) utilize the natural particle of natural and easy degraded to replace the use of part EVA in the pure EVA material prescription of footwear, thereby reduced the degradation time that the content of EVA in formula has shortened footwear EVA material effectively.2) footwear EVA mixing material is compared the pure EVA material of footwear and is had better slip resistance.
