Abstract
The invention discloses a flame-retardant insulated cable coating, comprising the following raw materials in parts by weight: 90-95 parts of silicone rubber, 5-10 parts of polyethylene, 6-9 parts of polyvinyl chloride, 2-3 parts of boronic acid, 25-30 parts of aluminum oxide, 3-5 parts of antimonous oxide, 27-30 parts of silica powder and 15-18 parts of titanium dioxide. The obtained coating has excellent fire resistance, and still can keep good insulativity after lasting the high temperature at 900 DEG C for 50 minutes.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of fire retardant insulating cable coating.
Background technology
Every year, because the electric wire fire causing that catches fire brings great loss to people, therefore, the measures for the prevention of fire of electric wire is very important.Thereby cable fire-refractory coating can effectively suppress flame transmission and spread protection electric wire.Though and existing cable coating can prevent that fire from occurring, insulativity after catching fire is poor need re-start insulativity processing to electric wire.
In sum, how to overcome the deficiencies in the prior art and become paint field problem demanding prompt solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and propose a kind of fire retardant insulating cable coating, coating of the present invention has good flame retardant resistance, and still can keep good insulativity under continuous high temperature.
Technical scheme of the present invention is as follows:
Fire retardant insulating cable coating, comprises the following raw material according to mass fraction meter: silicone rubber 90-95 part, polyethylene 5-10 part, polyvinyl chloride 6-9 part, boric acid 2-3 part, aluminium sesquioxide 25-30 part, antimonous oxide 3-5 part, silicon powder 27-30 part, titanium dioxide 15-18 part.
Described fire retardant insulating cable coating, comprises the following raw material according to mass fraction meter: 92 parts of silicone rubbers, 6 parts of polyethylene, 8 parts of polyvinyl chloride, 2.5 parts of boric acid, 28 parts of aluminium sesquioxides, 4 parts of antimonous oxides, 28 parts of silicon powders, 16 parts of titanium dioxide.
Described fire retardant insulating cable coating, the particle diameter of wherein said aluminium sesquioxide and silicon powder is 325 orders.
Preparation method of the present invention: each raw material is mixed to rear employing extruding coating method and be coated on cable surface, get final product.
beneficial effect:gained coating of the present invention has good flame retardant resistance, continues still to keep good insulativity after 50min under 900 ℃ of high temperature.
Embodiment
