Embodiment 4

[0088] The preparation method of the neoprene closed-cell foam material of embodiment 4 embodiment 1

[0089] (1) Mastication

[0090] Put the chloroprene rubber into a 22-inch open mill for mastication, and the temperature of the rolls of the open mill is controlled at 50°C. First, pass it 3 times with a 5mm roll distance to make it soft under heat, and then pass it 3 times with a 3mm roll distance. Thin pass for 10 minutes with a small roller distance of 2.5mm, and finally the lower sheet is cooled and parked for 24 hours with a roller distance of 5mm;

Abstract

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.

Description

technical field [0001] The invention relates to a high molecular polymer and its preparation, in particular to a neoprene closed-cell foaming material and its preparation method. Background technique [0002] At present, the rubber foamed sheets on the market mainly include modified nitrile rubber (NBR) foamed materials, silicone rubber foamed materials, EVA rubber foamed materials, PE rubber foamed materials, etc. Aging, weather resistance, flame retardant, acid and alkali resistance and chemical solubility are still not satisfactory. [0003] There is no report about utilizing chloroprene rubber as the foaming material of closed-cell foaming as raw material at present. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new type of foam material formed by closed-cell foaming with neoprene as the main material. The closed-cell foam material of neoprene of the present invention has excellent elasticity and also ha...
