Abstract
The invention relates to an oxygen separation layer filler of thermoplastic property, low smoke, no halogen and flame retardant polyolefin. The filler comprises the following components (by weight): 100 of polyolefin resin, 100 to 300 of flame retardant agent, 0 to 100 of flame retardant synergist, 0.5 to 5.0 of antioxidant, 1 to 10 of surface treatment agent, 0 to 20 of lubricant and 0 to 20 of other promoters. Compared with the prior art, the invention has the advantages of having optimal flame retardant performance, off-fire self-extinguish performance and no trickling after burning, being completely stuck on cable, forming a layer of hard carbon shell to isolate oxygen and heat, preventing burning and protecting the cable completely, etc.
Description
Technical field
The present invention relates to the electric wire stopping composition, relate in particular to a kind of thermoplastic low-smoke halogen-free flame-resistant polyolefin oxygen barrier filling material.
Background technology
Thermoplastic low-smoke halogen-free flame-resistant polyolefin oxygen barrier filling material is the material of a kind of high filling, high flame retardant; it can form the hard carbon shell of one deck on cable when burning; this layer carbon shell can starvation and warm; play the incendiary effect that stops; thereby the cable internal structure is protected completely; finally make cable reach very high flame retardant rating, satisfy its service requirements.The inner sheath that this material is used for power cable etc. plays the fire-retardant use of structure.
Whether the flame retardant rating that the quality of this material directly affects cable can reach requirement; owing to will form protection to cable; this material is not only required to have high flame retardant resistance; from fiery self-extinguishing, anti-molten drop etc.; crucial also the need forms the complete of hard carbon-coating and maintenance carbon hull shape shape after burning, so have high technical difficulty.Existing material has a large amount of drip phenomenons when mainly existing in burning, this can constantly produce new interface and can not put out certainly when burning, more can't form complete carbon hull shape shape, finally cause the cable inner insulation material burning and can't be by very harsh bunched burning test.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of have extremely excellent flame retardant properties, from fiery self-extinguishing can thermoplastic low-smoke halogen-free flame-resistant polyolefin oxygen barrier filling material.
