Description
Technical field
The present invention relates to a kind of expanded material and its manufacture method, more particularly to a kind of acrylonitrile butadiene rubber modified EVA foaming
Material and its manufacture method.
Background technology
Expanded material, refers to that the material that bubble makes the foaming of porous mass can be produced in material internal gasifier, such as
Manufacture foamed plastics, foam rubber, foamed resin etc..EVA (Ethylene Vinyl Acetate) is by ethene and acetic acid second
The copolymerization of alkene ester and be made, be a kind of thermoplastic, elastomer.Have the advantages that density is low, load can be absorbed and other elasticity
Body phase is than with excellent elasticity, pliability, stress cracking resistance, good plasticity and machinability.EVA expanded materials have
Have excellent chemical property, be widely used in manufacture footwear material, case and bag liner, toy material, sports goods material, building materials, with
And all kinds of emerging applications are such as electronic components and automotive trim.But EVA expanded materials have abscess larger, cell density
Small, in irregular shape, distribution is also uneven, and wearability is inadequate, the shortcomings of low temperature is hardened.
The content of the invention
Goal of the invention：Present invention aims at a kind of acrylonitrile butadiene rubber modified EVA expanded materials of offer and its manufacture method,
Solve the problem of above-mentioned EVA foaming material performances are poor.
Technical scheme：A kind of acrylonitrile butadiene rubber modified EVA expanded materials of the present invention, by weight, mainly by
Following components is constituted：20-30 parts of EVA, 5-10 parts of nitrile rubbers, 15-20 parts POE, 10-15 parts TPE, 1-3 parts of foaming agents, 0.5-
2 parts of zinc oxide, 0.5-2 parts of stearic acid, 1-5 parts of flowables, 0.5-1 parts of peroxide cross-linking agents, 10-15 parts of calcium carbonate, 10-15
Talcum powder.
The EVA is ethylene-vinyl acetate copolymer.
The nitrile rubber is to be prepared by butadiene and acrylonitrile through emulsion polymerization.Adding nitrile rubber can not only change
The shortcomings of kind EVA wearabilities are inadequate, low temperature is hardened, can also improve EVA superficial density, more preferable pliability and feel.Adjust
The amount of saving can adjust pliability and superficial density, and nitrile rubber can excessively cause poor processability.
The POE is the copolymer of a kind of ethene and butylene, and POE molecular weight distribution is wide, can rushed system
Play scattered, shock absorbing when hitting, improve the impact strength and elongation at break of system, regulation POE consumptions can adjust anti-
Zhang Qiangdu, elongation at break and elasticity.
Zinc oxide is used as blowing promotor, and regulation consumption can adjust expansion rate.Zinc oxide content is less than 0.5 part, foaming agent
Gas forming amount is small to cause foaming agent consumption increase, expansion rate slowly, and the sulfur foam time will extend, and energy consumption increase, zinc oxide is excessive,
Then foam and cause rate of closed hole to decline soon, product resilience is poor.
TPE (Thermoplastic Elastomer) of the present invention is to be modified granulation with SEBS and White Mineral Oil to form, and is
Thermoplastic elastomer (TPE), can increase substantially impact strength, resistance to weather and heat-resistant aging.
The foaming agent is azodicarbonamide, and effect is to adjust consumption adjustable product density and hardness.
The peroxide cross-linking agent is cumyl peroxide, for adjusting crosslink material density.Peroxide crosslinking
Agent is very few, and sulfur foam process middle crosslink density is low to cause melt strength low, and bag does not live gas and forms continuous pore structure or nothing
Method foams；Peroxide cross-linking agent is excessive, and sulfur foam process middle crosslink density is too high, causes melt strength too high and foams again
Rate is small or can not foam.
The flowable is Tissuemat E, gloss and processing characteristics for increasing product.
Stearic acid is used as helping foaming and lubricant, regulation expansion rate and anti-sticking effect in operating process.Stearic acid is very little
Foaming is slightly slack-off, material slightly sticky equipment in operation；Too many then foam and slightly accelerate, being skidded during mixing, heating is slow, and mill process exists
Easy roll release in mill.
Calcium carbonate is used as filler, reduces cost, improves foaming nucleation abscess quality.A small amount of addition powdered whiting can be adjusted
Save foaming nucleation quality, a large amount of additions are to reduce production cost；Excessive addition can cause product density height, intensity resilience
It is deteriorated, feel is deteriorated.
Talcum powder：As filler, the hardness and intensity of expanded material can be adjusted by reducing cost, a small amount of addition talcum powder,
Excessive addition can cause to reduce the tensile strength and bending modulus of product.
