Abstract
The invention discloses a kind of neoprene microcellular foam material and preparation method thereof, its formula includes 100 parts of neoprene, 0-100 parts of filler, 0-20 parts of plasticizer, 2-12 parts of vulcanizing agent；0-5 parts of vulcanization accelerator, 0.5-2 parts of age resistor, and preparation method is provided with above-mentioned formula.The present invention have foaming, cutting, abnormity cutting, it is hot-forming, punching, grinding and be combined etc. manufacturing process and process equipment, can be various different sizes product be processed.
Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of neoprene microcellular foam material and its system
Preparation Method.
Background technology
What micropore foamed polymer referred in polymeric matrix containing abscess-size from 0.1 micron to tens microns
Porous polymer, due to application development of the pore fluid technology on microcellular foam material so that microporous foam
The industrialized production of polymer becomes reality.Micropore foamed polymer material in energy absorption heat-insulating sound-insulating,
And have excellent performance in optical property, it is described as " 21 century new material ".
Neoprene is a class synthetic rubber of excellent combination property, so also referred to as Multifunctional rubber.Chlorine
Buna be polarity from reinforced rubber, crystallinity is stronger, and intermolecular active force is big, possesses higher mechanics
Performance.Neoprene has good resistance to ozone, weatherability, and resistance to ozone, weatherability are only
Inferior to EP rubbers and butyl rubber；Heat resistance is then suitable with NBR, can under 150 DEG C of high temperature the short time make
With.Neoprene has outstanding dynamic property, such as fatigue performance, available for timing belt, in cog belt；
With outstanding bond properties, so being widely used as adhesive.With pretreated framework material (such as metal,
Textile, glass have good adhesive power.Neoprene has excellent fire resistance, CR oxygen simultaneously
Index is higher, and about 38.41, belong to high nonflammable material.
CR is influenceed due to its structure, makes it have excellent weatherability, oil resistivity, anti-flammability etc., extensively should
For electric wire foreskin, sebific duct, offset plate etc., and CR expanded materials have more preferable tensile strength and tension and compression bullet
Property, makes it can apply to automotive trim, diving dress, the field such as air equipment.
The content of the invention
It is an object of the invention to provide a kind of neoprene microcellular foam material and preparation method thereof, the present invention can
Applied to packaging material, building, building, vehicle, ship, thermal insulation, insulation, sound insulation, moistureproof field,
With foaming, cutting, abnormity cutting, hot-forming, punching, grinding and manufacturing process and the processing such as compound
Equipment, can be processed for the product of various different sizes.
A kind of neoprene microcellular foam material and preparation method thereof, its formula is as follows：100 parts of neoprene,
0-100 parts of filler, 0-20 parts of plasticizer, 2-12 parts of vulcanizing agent；0-5 parts of vulcanization accelerator, age resistor 0.5-2
Part.
Wherein, neoprene is sulphur adjustment type or non-sulphur adjustment type；
Wherein, filler is the one or more in carbon black, white carbon, calcium carbonate, kaolin, chopped fiber；
Wherein, plasticizer is in aromatic naphtha, paraffin oil, naphthenic oil, dioctyl phthalate (DOP)
One or more；
Wherein, vulcanizing agent is that magnesia, zinc oxide are used in combination, magnesia for high activity or lead orthoplumbate,
2,5- dimethyl -2,5- bis(t-butylperoxy)s hexane (one kind in double two or five).
Wherein, vulcanization accelerator is ETU, DM, TMTM, the one or more in S.
Wherein, age resistor is 2,2,4- trimethyls 1,2- dihydros quinoline (RD), N- phenyl-N`- cyclohexyl
