Abstract

The invention relates to a chloroprene rubber sponge foam material and discloses a special rubber sponge foam material with high flame resistance and high tear strength. The special rubber sponge foam material is prepared from the following components in parts by weight: 55-90 parts of chloroprene rubber, 12-22 parts of rubber softening oil, 6-15 parts of factice, 4-10 parts of a foaming agent, 3-5 parts of zinc oxide, 3-8 parts of magnesium oxide, 0.6-0.8 part of a vulcanization accelerator, 6-17 parts of antimonous oxide, 3-12 parts of decabromodiphenyl ether, 1-3 parts of an anti-aging agent, 1-3 parts of an activator and 3-7 parts of carbon black. The decabromodiphenyl ether and antimonous oxide with synergistic interaction are added to the chloroprene rubber, are matched with the rubber softening oil and the factice for use, the vulcanizing agent, the vulcanization accelerator, the foaming agent and related assistants are added, so that the obtained chloroprene rubber sponge foam material with flame resistance and high tear strength is suitable for diving equipment products, with high tear strength, such as diving suit and surfing clothes.

Description

technical field [0001] The invention relates to a neoprene sponge foam material, and also relates to its preparation method and application. Background technique [0002] Diving suits, surfing suits and other products are made of neoprene sponge foam material. Due to the particularity of wearing and using the product, it has extremely high requirements on the elongation, softness and tear strength of the material. Therefore, in the material formula Add a lot of petroleum softeners and vulcanized vegetable ointment. Neoprene itself contains halogen and has a certain flame retardancy, but due to the addition of a large amount of petroleum softeners and vulcanized vegetable ointment, the flame retardancy of neoprene itself has been greatly reduced. In order to improve the flame retardancy of products such as diving suits and surfing suits, it is necessary to develop a neoprene sponge foam material with high flame retardancy on the basis of maintaining high elongation, softness...
