Embodiment

[0029] The production of EPDM rubber for halogen-free flame-retardant sealing strips in Examples 1-7 was carried out according to the composition ratio in Table 1.

[0030] According to the following steps, the EPDM rubber used for the halogen-free flame-retardant sealing strip of the present invention is manufactured:

[0031] (1) Raw material preparation: According to the ingredients and proportions in Table 1, weigh EPDM rubber, carbon black, flame retardant, softening plasticizer, and activator respectively and mix them to form ingredient A, and weigh the vulcanizing agent form ingredient B;

[0032] (2) The first mixing: Put ingredient A into the internal mixer for 60-90 seconds, lift the hammer to clean, then press the hammer to mix for 60-90 seconds, lift the hammer to clean again (temperature 140-150°C), and then press the hammer Mix for 60-80 seconds and unload (temperature 150-170°C) to the cutting machine to discharge the sheet to make the mixed rubber A;

Abstract

The invention discloses a halogen-free flame-retardant ethylene-propylene-diene monomer rubber for sealing strips. The halogen-free flame-retardant ethylene-propylene-diene monomer rubber for sealingstrips comprises 24-27 wt% of ethylene-propylene-diene monomer rubber, 15-19 wt% of carbon black, 34-40 wt% of a flame retardant, 14-17 wt% of a softening plasticizer, 2.5-3 wt% of an activator and 2.3-2.5 wt% of a vulcanizing agent. The halogen-free flame-retardant ethylene-propylene-diene monomer rubber for sealing strips has the characteristics of high strength, good high-temperature aging resistance and high flame retardancy in a use environment, and also has a long service life.

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...
