Environment-friendly expanding fireproof synthetic rubber, fireproof cable and rubber coated fireproof pipeline

Abstract

The invention relates to the technical field of rubber production, and particularly relates to environment-friendly expanding fireproof synthetic rubber and a fireproof cable and a rubber coated fireproof pipeline using the fireproof synthetic rubber. The environment-friendly expanding fireproof synthetic rubber comprises the following substances in parts by weight: 30-50 parts of water-based resin, 10-20 parts of water, 10-30 parts of expanded graphite, 5-15 parts of ammonium polyphosphate, 8-12 parts of vermiculite, 2-5 parts of perlite, 3-5 parts of tackifier, 3-5 parts of thickener, 1-3 parts of lightning protection agent and 1-3 parts of defoamer. The environment-friendly expanding fireproof synthetic rubber provided by the invention combines the characteristics of environment friendliness, flame retardancy, fire proofness and the like, and can be used instead of traditional toxic synthetic rubber which sends out pungent smell and generates black smoke during combustion; and the product takes the perlite tailing as the raw material, thereby achieving the effects of energy saving and environment friendliness. By using the environment-friendly expanding fireproof synthetic rubber as a coat, the invention also provides the fireproof cable and the rubber coated fireproof pipeline. Fire resistance tests prove that the fireproof cable and the rubber coated fireproof pipeline have the advantages of the environment-friendly expanding fireproof synthetic rubber.

Description

technical field [0001] The invention relates to the technical field of rubber production, in particular to an environment-friendly expanded fireproof synthetic rubber, and a fireproof cable and a rubber-coated fireproof pipe using the fireproof synthetic rubber. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. Ordinary rubber products have low flame retardancy and are easy to burn, which greatly reduces their scope of use. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a fire-resistant rubber composition with high flame-retardant performance and non-combustibili...

Problems solved by technology

[0004] The cable mainly consists of an inner cable core and a sheath covering the cable core. The sheath covering the cable is generally made of rubber. When some special cables are in use, there will be a lot of waste heat inside the cable core. If the cable core If the selection of the outer sheath and filling is not reasonable, then the waste heat will damage the filling and sheath, and even cause a fire, which is extremely dangerous
