Abstract

The invention relates to foaming SCR and a manufacturing method thereof. The foaming SCR comprises a main ingredient, a plasticizer, a dispersing agent, a foaming agent, sulfur, a promoter, an activator, a protective agent and a filler and particularly comprises 100 weight parts of main ingredient, 35 to 60 weight parts of plasticizer, 1 to 2 weight parts of dispersing agent, 5 to 15 weight parts of foaming agent, 4 to 8 weight parts of active zinc oxide, 1 to 2 weight parts of stearic acid, 1 to 2 weight parts of high-activity magnesium oxide, 0.4 to 1 weight part of sulfur, 0.7 to 3 weight parts of promoter, 3 to 6 weight parts of protector and 100 to 200 weight parts of filler. In the main ingredient, the weight part ratio of neoprene to emulsion polymerized butadiene styrene rubber to cis-polybutadiene rubber to solution polymerized butadiene styrene rubber is 30:(10-20):(20-40):(20-30). The foaming SCR offers a soft handfeel, is very elastic and has a uniform and fine close pore structure, high waterproof performance, high thermal-insulation performance and high seawater pumping resistance.

Description

technical field [0001] The invention relates to an SCR foam rubber, which belongs to the technical field of foam rubber. The invention also relates to a manufacturing method of the SCR foam rubber. Background technique [0002] At present, the styrene-butadiene foam rubber sheet mainly used in the market has low tensile strength, tear strength, and elongation. It is very limited in use and is not flame-retardant. With the demand for the use of foamed rubber in the fields of navigation, fishing, diving, surfing, etc., people put forward new performance requirements for foamed rubber. [0003] The performance index of the existing styrene-butadiene foamed rubber sheet is as follows: [0004] [0005] Obviously, the existing styrene-butadiene foamed rubber sheet cannot meet the requirements for the use of foamed rubber in fields such as navigation, fishery, diving, and surfing. Contents of the invention [0006] The primary purpose of the present invention is to overcom...
