Embodiment 1

[0021] Put 100 parts of EPDM rubber into a double-roller mixer for 5 minutes, then add 10 parts of naphthenic oil, 30 parts of carbon black, 20 parts of triphenyl phosphate, 25 parts of chitosan, 10 parts of hydrotalcite , 0.5 parts of stearic acid, 1.0 part of zinc oxide and kneading for 8 minutes, then add 4.0 parts of sulfur, 2.0 parts of TMTD, 1.0 part of DM, 4.5 parts of AC and mix uniformly, pass through 8 times and then release the film to obtain EPDM Rubber blends. Then put the EPDM rubber blend in a flat vulcanizer, vulcanize and foam for 12 minutes at a temperature of 160°C and a mold pressure of 10MPa to obtain a flame-retardant EPDM rubber foam material. The limiting oxygen index of flame retardant materials is 28.7%.

Embodiment 2

[0023] The preparation operation of the flame-retardant EPDM foam material is the same as in Example 1. The formulation of the flame-retardant EPDM foam material is 100 parts EPDM rubber, 35 parts naphthenic oil, 30 parts carbon black, 5 parts trioctyl phosphate, 10 parts chitosan, 45 parts hydrotalcite, 1.5 parts stearic acid, 3.5 parts zinc oxide, 8.5 parts sulfur, 4.5 parts TMTD, 3.5 parts DM, 1.5 parts AC, the vulcanization foaming temperature is 190℃, the vulcanization foaming time is 3 minutes, the molding pressure is 1MPa, and the resistance is measured The limiting oxygen index of the fired EPDM foam material is 26.2%.

Embodiment 3

[0025] The preparation operation of the flame-retardant EPDM foam material is the same as in Example 1. The formulation of the flame-retardant EPDM foam material is 100 parts EPDM rubber, 15 parts naphthenic oil, 20 parts carbon black, 10 parts triisopropyl phosphate, 20 parts chitosan, 15 parts water Talc, 1.0 part stearic acid, 2.0 parts zinc oxide, 5.5 parts sulfur, 2.5 parts TMTD, 1.5 parts DM, 2.5 parts AC, vulcanization foaming temperature is 180℃, vulcanization foaming time is 6 minutes, molding pressure is 3MPa, measured The limiting oxygen index of the flame-retardant EPDM foam material is 28.7%.

Abstract

The invention relates to an inflaming retarding ethylene-propylene-diene-monomer rubber foam material and a preparing method thereof. The inflaming retarding ethylene-propylene-diene-monomer rubber foam material is mainly prepared from, by weight, 100 parts of ethylene-propylene-diene-monomer rubber, 10 parts to 35 parts of naphthenic oil, 10 parts to 30 parts of carbon black, 5 parts to 20 parts of organo-phosphorus flame retardant, 10 parts to 25 parts of chitosan, 10 parts to 45 parts of hydrotalcite, 0.5 part to 1.5 parts of stearic acid, 1.0 part to 3.5 parts of zinc oxide, 4.0 parts to 8.5 parts of sulphur, 2.0 parts to 4.5 parts of tetramethyl thiuram disulfide (TMTD), 1.0 part to 3.5 parts of 2, 2'- disulfbenzothiazole (DM) and 1.5 parts to 4.5 parts of azodicarbonamide (AC). The inflaming retarding ethylene-propylene-diene-monomer rubber foam material has the advantages of being free of halogen, good in flame retardant performance, excellent in combination performance and the like, and is suitable for industries such as building heat preservation, auto spare parts, waterproof materials, electric wires, air conditioner cooling and war industry apparatuses.

Description

Technical field [0001] The invention relates to a foam material, in particular to a flame-retardant EPDM rubber foam material and a preparation method thereof. Background technique [0002] Buildings are the main sector of carbon dioxide emissions, and their energy consumption accounts for about one-third of the total energy consumption of society. Therefore, in order to achieve the goal of reducing my country’s carbon dioxide emissions per unit of GDP by 40%-45% compared with 2005, building energy conservation The implementation of the target is crucial and is an important measure to realize my country's "low-carbon economy". During the "Twelfth Five-Year Plan" period, the cumulative newly built building area in cities and towns across the country will reach 4 billion to 5 billion square meters. At the same time, my country's existing buildings will reach more than 43 billion square meters, 95% of which are high-energy buildings. my country's unit building energy consumption is ...
