Description

technical field

[0001] The invention belongs to the field of rubber, and in particular relates to EPDM rubber for a halogen-free flame-retardant sealing strip and a preparation method thereof. Background technique

[0002] The sealing strip is a product that seals something so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. The sealing strips are made of rubber, paper, metal, and plastic. , A variety of materials.

[0003] Generally speaking, the sealing strips on new energy vehicles, high-speed rail and doors and windows are PVC rubber sealing strips and halogen strips, which are not environmentally friendly and cannot be reused. The smell is also very strong, which is not good for health. Contents of the invention

[0004] In view of the above problems, the present invention provides a kind of EPDM rubber for halogen-free flame-retardant sealing strips, which has high strengt...
