The invention relates to a
macromolecule polymer and a preparation method thereof, in particular to a
neoprene closed cell foamed material and a preparation method thereof. The
neoprene closed cell foamed material is prepared from
neoprene, strong
magnesium powder or
calcium carbonate,
carbon black, a vulcanizing accelerator, a
foaming agent, carbamide resin, paraffin, an age inhibitor, an
antioxidant, naphthenoid oil, and the like according to a certain
mass ratio. The invention also provides the preparation method of the neoprene
closed cell foamed material, which comprises the process of closed
cell foaming in a mold twice. The material produced by closed
cell foaming has good elasticity and performance of resisting
ageing, weather,
flame, acid, alkali, oil and chemical
solubility, can be used under the condition of a severe environment and conforms to requirements of
environmental protection. Through SGS detection, the material conforms to a new European Union standard REACH. In addition, the preparation process has the advantages of simple
process control, energy saving, reduced human resource cost and favorable economic and
social benefits.
