Embodiment 1

[0056] Neoprene 90 EPDM 120

[0057] Nano Zinc Oxide 8 Stearic Acid 3

[0058] Magnesium hydroxide 20 Aluminum phosphate 4

[0059] Magnesium silicate 8 Sodium silicate 6

[0060] Mica powder 10 Silicon carbide 7

[0061] Antiaging agent 4 Calcium carbonate 6

[0062] Hydroxy silicone oil 4 Hydrogen silicone oil 3

[0063] Silica 3 Dimethicone 2

[0064]Dibutyl phthalate 1 N-tert-butyl-2-benzothiazole sulfenamide 2

[0065] 2-thiol imidazoline 1.

[0066] The anti-aging agent is N-phenyl-α-aniline and N-N'-diphenyl-p-phenylenediamine, and the weight ratio of the two is 2:1.

[0067] Fire resistance test:

[0068] It can play a very good flame retardant effect, and it is not easy to burn in case of fire, but it cannot form a hard shell, and the surface still has a certain degree of ceramicization, which can also play a very good protective role. It can reach the UL94V0 flame retardant level (UL94V0 is the American flame retardant material standard).

Abstract

The invention belongs to the field of rubber, and particularly relates to a fire-resistant rubber. The fire-resistant rubber comprises the following components in parts by weight: 50-160 parts of neoprene, 60-150 parts of ethylene-propylene-diene rubber, 4-12 parts of nano zinc oxide, 1-5 parts of stearic acid, 10-25 parts of magnesium hydroxide, 2-6 parts of aluminium phosphate, 2-12 parts of magnesium silicate, 2-10 parts of sodium silicate, 4-18 parts of mica powder, 2-12 parts of silicon carbide, 1-5 parts of an antiager, 1-10 parts of calcium carbonate, 1-7 parts of hydroxyl silicone oil, 1-6 parts of hydrosilicone oil, 1-5 parts of white carbon black, 1-5 parts of simethicone, 1-5 parts of dibutlyl phthalate, 1-5 parts of N-tert-butylbenzothiazole-2-sulphenamide and 1-5 parts of 2-imidazolidinethione. The invention has the benefits that the fire-resistant rubber prepared by the formula has good refractability and can play a certain protective role in a big fire to reduce loss caused to people by the big fire.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to a fire-resistant rubber. Background technique [0002] Usually silicone rubber itself is not fire resistant. However, in the current fire accidents, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a kind of fire-resistant silicone rubber, which is required to play a certain protective role in the fire, and can reduce the electricity brought to people in the fire. Loss, reduce the harm of electricity. Refractory rubber is made of chloroprene as the main raw material through homopolymerization or copolymerization of a small amount of other monomers. Such as rubber products with high tensile strength, excellent heat resistance, light resistance, aging resistance, and oil resistance are better than natural rubber, styrene-butadiene rubber, and butadiene rubber. It has strong flame resistance and excellent flame retardancy resistance, hi...
