Problems solved by technology

The main chain of ethylene propylene diene monomer (EPDM) is composed of chemically stable saturated hydrocarbons, and the side chain contains unsaturated double bonds, so it has excellent aging resistance and certain ozone resistance, but its flame retardancy is poor. Ozone generators that produce hi...

Embodiment 1

[0049] Embodiment 1 provides a flame-retardant composite rubber material resistant to high-concentration ozone, which is prepared by the following method:

[0050] (1) Weigh 65 parts of EPDM rubber, 35 parts of chlorosulfonated polyethylene, 50 parts of reinforcing agent, 35 parts of flame retardant material, 10 parts of paraffin oil, 8 parts of antiozonant, 5 parts of zinc oxide in proportion by weight parts, 3 parts of magnesium oxide, 0.5 parts of stearic acid, 2.5 parts of processing aids, 3.2 parts of vulcanizing agents, 2 parts of pigments, and 1.2 parts of crosslinking additives; among them, the antiozonant is antiaging agent AFS and microcrystalline wax by mass A mixture with a ratio of 1:9, the reinforcing agent is a mixture of white carbon black and barium sulfate in a mass ratio of 4:1, and the flame retardant material is a mixture of antimony trioxide and decabromodiphenylethane in a mass ratio of 1:3 Composite flame retardant, the processing aid is WB42, the vulca...

Embodiment 2-6

[0057] The difference between the flame-retardant composite rubber material against high-concentration ozone provided by Examples 2-6 and Example 1 is only that the proportioning of raw material components is different, and the preparation method is the same as that of Example 1, and the proportioning of raw materials in Examples 2-6 is as follows: Shown in table 1; Wherein, reinforcing agent, antiozonant, flame retardant material, processing aid, vulcanizing agent, pigment, crosslinking auxiliary agent are all identical with embodiment 1.

Abstract

The invention belongs to the field of rubber materials, and particularly relates to a flame-retardant composite rubber material capable of resisting high-concentration ozone and a preparation method thereof. The composite rubber material comprises the following raw materials in parts by weight: 70-30 parts of ethylene propylene diene monomer, 30-70 parts of chlorosulfonated polyethylene, 30-60 parts of a reinforcing agent, 25-50 parts of a flame-retardant material, 5-15 parts of paraffin oil, 5-12 parts of an anti-ozone agent, 4-6 parts of zinc oxide and 0.3-1 part of stearic acid. In the preparation process of the flame-retardant composite rubber, the ethylene propylene diene monomer, the chlorosulfonated polyethylene and the magnesium oxide are mixed, then the active agent, the aniseed and the oil material are added step by step, low-temperature mixing is performed, high-temperature conditions are not needed, and the production process is simple, energy-saving and efficient. Throughreasonable formula design and process optimization, the prepared composite rubber material has the characteristics of high-concentration ozone resistance and favorable flame retardancy, and can resistthe ozone concentration of 200ppm on an ozone generator so as to keep intact.

Description

technical field [0001] The invention belongs to the field of rubber materials, and in particular relates to a high-concentration ozone-resistant flame-retardant composite rubber material and a preparation method thereof. Background technique [0002] Ozone has strong oxidizing and bactericidal properties, and can be widely used in drinking water purification, food processing and storage, fruit and vegetable preservation, air purification, medical and health care, chemical oxidation and other fields. At present, the application concentration of ozone in my country generally does not exceed 10ppm, and the application in clinical medicine may reach 20ppm, while the local concentration of ozone generators can be as high as 170-300ppm, and the output concentration can also reach 150ppm. Therefore, the ozone generator has high requirements for accessories, and usually uses rubber materials with good ozone resistance, aging resistance and good insulation properties. However, most ...
