Beschreibung
Zusammenfassung:	The invention discloses a neoprene material composed of the following raw materials, by weight: 1-2 parts of zinc oxide, 0.2-0.6 parts of 8-10% sulfuric acid, 5-8 parts of melamine, 26-30 parts of a 37% formaldehyde solution, 7-10 parts of urea, 0.6-1 parts of p-chlormetaxylenol, 4-7 parts of vinyl carboxylate, 2-3 parts of ammonium trimolybdate, 0.7-2 parts of ascorbic acid, 47-50 parts of attapulgite, 6-10 parts of microcrystalline cellulose, 1-1.2 parts of isopropanol, 3-4 parts of maleic anhydride, 2-3 parts of sulfur, 3-4 parts of an anti-aging agent 688, and 200-230 parts of neoprene S40V. According to the invention, under the crosslinking effect of maleic anhydride, microcrystalline cellulose forms a closer network structure in melamine resin formed by melamine, urea and formaldehyde, such that resin viscosity and tensile deformation resistance are greatly improved, and certain reinforcement and tackification effects are performed in the rubber material. Therefore, flexure cracking resistance, hot air aging resistance and stability of the material are improved.
