Abstract
The invention discloses a thermoplastic low-smoke halogen-free fire-retardant sheath material. The material comprises the following components in weight portion: 100 portions of base material, 40 to 60 portions of aluminum hydroxide, 40 to 50 portions of calcium carbonate, 0.5 to 1 portion of antioxidant, 5 to 7 portions of surface treating agent, 3 to 4 portions of lubricant and 4 to 6 portions of coloring agent. The thermoplastic low-smoke halogen-free fire-retardant sheath material provided by the invention has the advantages of less raw material, simple composition, low energy consumption when processed, high product utilization rate, so that the cost is lowered, and the industrialization is easy to realize; moreover, the thermoplastic low-smoke halogen-free fire-retardant sheath material of the invention also has good mechanical property, processability and fire retardant performance.
Description
Technical field
The present invention relates to technological invention in the electric wire industrial circle, relate in particular to a kind of prescription of thermoplastic low-smoke halogen-free flame-retardant sheath material.
Background technology
From the late nineteen eighties, macromolecular material by a large amount of use of each country, is mainly used in electric wire, electric switch, telepilot, televisor, washing machine shell etc.Because macromolecular material is easy to burning, so disaster hidden-trouble become serious social concern, causes the great attention of national governments, the research of novel material is extremely urgent.
Adding fire retardant in macromolecular material is effective ways of fire preventing, and China has 80% to be halogen containing flame-retardant in the industrial fire retardant that uses at present, is the brominated flame-retardant of representative with polybromodiphenyl ether and polybrominated biphenyl material particularly.But it is reported,, when burning, can produce many bromos cumarone (PBDF), therefore be restricted with strong carcinogenesis with the plastics of this based flame retardant.Use halogen-free flame retardants that it is substituted at present abroad in a large number.And starting is studied in this respect than later by China, in output with also use a certain distance with developed country qualitatively.
Halide-free smokeless type fire retardant material does not produce obnoxious flavour when burning, the amount of being fuming is also fewer, can reduce to minimum to loss in fire failure, is therefore praised highly by various countries.Yet the halide-free smokeless type fire retardant material of various countries research at present is very unripe, and the material that has does not have favorable mechanical, process difficult and shortcomings such as flame retardant properties is not strong.
The present invention is directed to influences mechanical property and these two keys of processing characteristics, has used special formula, for the development of thermoplastic low-smoke halogen-free flame-retardant sheath material breaks a new path.
Summary of the invention
Technical problem to be solved by this invention provides a kind of thermoplastic low-smoke halogen-free flame-retardant sheath material prescription, makes it have good processing properties and mechanical property.
For realizing above-mentioned technical problem, the technical solution adopted in the present invention is as follows:
A kind of thermoplastic low-smoke halogen-free flame-retardant sheath material, it comprises following compositions in weight portion: 100 parts of base-materials, 40～60 parts in aluminium hydroxide, 40～50 parts in lime carbonate, 0.5～1 part in oxidation inhibitor, 5～7 parts of surface treatment agents, 3～4 parts of lubricants, 4～6 parts of tinting materials.
Wherein, described base-material is the arbitrary proportion mixture of polyolefine EVA and LLDPE.
Wherein, described oxidation inhibitor is AT-10 (oxidation inhibitor AT-10 is four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester).
Wherein, described surface treatment agent is silane coupling agent or titante coupling agent.
Wherein, described lubricant is a silicone oil.
Wherein, described tinting material is the look mother.
Beneficial effect: thermoplastic low-smoke halogen-free flame-retardant sheath material provided by the invention, raw material is few, composition is simple, processing is got up to consume low, product utilization rate height, thereby cost is reduced, be easy to realize industrialization, and thermoplastic low-smoke halogen-free flame-retardant sheath material of the present invention has favorable mechanical performance, processing characteristics and flame retardant properties.
