Abstract
The invention discloses an environment-friendly halogen-free rubber sheath for a flame-retardant cable, belonging to the technical field of flame-retardant rubber. The environment-friendly halogen-free rubber sheath for the flame-retardant cable comprises a rubber base body and nanometer flame-retardant reinforcing agent, wherein the nanometer flame-retardant reinforcing agent is formed by mixing kaolin and brucite, wherein the particle size of the nanometer flame-retardant reinforcing agent is bigger than 5000 meshes; and the weight ratio of the kaolin to the brucite is 1:(0.5-1.5). The conventional rubber method for preparing the environment-friendly halogen-free rubber sheath for flame-retardant cable comprises the following steps: weighing the materials in proportion, adding the material to an internal mixer for mixing; and cooling, drying, folding and batching off the mixed materials. The cable rubber sheath provided by the invention is free of harmful flame-retardant substances, and adopts the nanometer flame-retardant reinforcing agent which is formed by mixing the kaolin and the brucite, so that the tensile strength of the mineral flame-retardant cable sheath and tear strength of the pants-shaped sample are increased, and the elasticity, the elongation and the oxygen index are greatly improved.
Description
Technical field
The present invention relates to flame retardant rubber technical field.
Background technology
The formula of tradition flame-proof cable sheath is complicated, tens kinds of batchings at least, at most twenties kinds of batchings, various starting material function singleness.Furnish type is various, blending process is also complicated, and it is long that the cycle investigated one by one by the various material that encounters problems, various batching interreaction more problems, produces bring a lot of trouble to sheath.
The fire retardant that tradition mining flame-retardant cable is conventional is the fire retardant such as antimonous oxide and decabromodiphenyl oxide, with white carbon black, carbon black, cooks strengthening agent.Antimonous oxide and decabromodiphenyl oxide flame retardant effect are better, but burning fuming amount is large, release toxic gas, easily causes the secondary disaster; Carbon black white carbon black reinforcing effect is better, but its raw material sources are in oil, and petroleum resources are day by day exhausted and cost is high, so need a kind of both environmental protection flame retardants and reinforcing property substitutes their material compared with high energy, reduces social cost, to promote productivity progress.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Environment-friendlyhalogen-free halogen-free rubber sheath for flame-retardant cable, not containing harmful fire retardant matter, kaolin is adopted to mix the fire-retardant strengthening agent of the nano formed with brucite, the tensile strength of mining flame-retardant cable sheath, pants type sample tear strength are increased, and elasticity, elongation and oxygen index improve greatly.
