Embodiment 1-6 and comparative example 1-3

[0025] In Examples 1-6 and Comparative Examples 1-3, halogen-free flame retardant EPDM rubber products were prepared according to the following preparation methods and the dosage shown in Table 1, respectively, and a blank example without adding a flame retardant was additionally set. Wherein the preparation method is:

[0026]Take 100 parts by weight of raw EPDM rubber (brand P750NR, Mitsui Chemicals, Japan, whose third monomer is ENB), thinly pass 4 times on an open mill, and after wrapping rolls, adjust the roll distance to 1 mm, and sequentially Add stearic acid, zinc oxide, melamine cyanurate (MCA), aluminum diethylphosphinate (ADP) and aluminum hydroxide, mix for 12min, add sulfur and vulcanization accelerator (including DM, CZ, industrial grade , Guangzhou Donghong Chemical Factory), knead evenly, beat the triangle bag 5 times, roll 3 times, and then unload the film, and vulcanize it with a flat vulcanizer at 160 ° C × 10 min to obtain a halogen-free flame retardant EP...

Abstract

The present invention relates to the field of flame-retardant agents, particularly to an intumescent halogen-free flame-retardant agent, a halogen-free flame-retardant ethylene propylene diene monomer composition containing the intumescent halogen-free flame-retardant agent, a halogen-free flame-retardant ethylene propylene diene monomer obtained by mixing and vulcanizing the halogen-free flame-retardant ethylene propylene diene monomer composition, and applications of the halogen-free flame-retardant ethylene propylene diene monomer, wherein the intumescent halogen-free flame-retardant agent contains the mixture of melamine cyanurate and aluminum diethylphosphinate and / or aluminum hydroxide. According to the present invention, the intumescent halogen-free flame-retardant agent has good flame-retardant property, and the prepared halogen-free flame-retardant ethylene propylene diene monomer has high elongation at break.

Description

technical field [0001] The invention relates to the field of flame retardants, in particular to an intumescent halogen-free flame retardant, a halogen-free flame retardant EPDM rubber composition containing the intumescent halogen-free flame retardant, and a A halogen-free flame-retardant EPDM rubber rubber obtained by mixing and vulcanizing a halogenated flame-retardant EPDM composition and its application. Background technique [0002] EPDM is an ethylene-propylene-non-conjugated diene copolymer with good weather resistance, electrical insulation, ozone resistance and chemical resistance, and the flame retardant modification of EPDM is designed to Overcome the flammability of EPDM and improve the safety of its application. At present, commercial flame retardant EPDM materials mainly use bromine-antimony oxide flame retardant system, but halogen-containing flame retardants are gradually abandoned by new environmental protection regulations due to the production of toxic an...
