Description
Technical field
The present invention relates to a kind of halogen-free flame retarding polymer sheet material, more particularly, the present invention relates to a kind of polypropylene-base gasket material, belong to a kind of insulating material with the feature of environmental protection, high flame retardant and high heat resistance.
Background technology
Polypropylene flame redardant is rolled into sheet material between 0.125mm～0.75mm have advantages such as fire-retardant, withstand voltage, heatproof, anti-tear anti-folding, be widely used as the isolated edge material of pad of live parts in the electronic and electrical equipment.Now on world market the usage quantity maximum be the FORMEX of fire-retardant American I TW company
TM, FORMEX
TMGK and STATEX
TMThe polypropylene flame redardant sheet that fire-retardant polypropylene insulation pad, the US of ITW house journal 5521003 disclose with two (2,3-dibromopropyl) ether preparations of homo-polypropylene, Co-polypropylene and tetrabromo-bisphenol has excellent flame-retardant performance and anti-folding tear resistance.Yet the halogen flame retardant material is referred to that its processing, burning and removal process can discharge the high malicious carcinogenic substance of dioxin and benzene furans, serious harm environment and HUMAN HEALTH in a lot of environmental protection appraisal reports in recent years.In February, 2003, European Union at first announced the ROHS instruction (electronic motor product hazardous substance limits the use of instruction) of restriction halogen, Japan, Germany, the U.S., China etc. have also launched respectively relevant environmental law rules, worldwide production enterprise, supplier and the client of electronic electric equipment made the regulation of insurance the most in order to allow self product and production line can tackle existing and environmental legislation in the future in supply chain inside---and " zero halogen ".Fire-retardant polypropylene sheet must be replaced employed bromine class, could continue to use in electronic and electrical equipment as insulating material.Use comparatively sophisticated polypropylene halogen-free flame retardants to comprise oxyhydroxide, phosphorus system and nitrogen system and composite at present.The oxyhydroxide fire retardant is representative with magnesium hydroxide, aluminium hydroxide, even but addition also is difficult to make polypropylene to reach the 0.125mm～desired UL94 V0 of 0.75mm insulating trip flame retardant rating more than 60wt%, it is serious to cause polypropylene flame redardant processing difficulties, anti-tear fold resistance to descend on the contrary.Phosphorus flame retardant is representative with red phosphorus, organophosphate, addition is low than oxyhydroxide, also need bigger addition just can reach the high flame retardant grade,, and then reduce the insulation level and the use range of polypropylene foil again because of the fire retardant addition causes the big and rate of release height of goods water-intake rate greatly.The nitrogen flame retardant is representative with melamine class, triazines, and often no matter addition also can't be issued to high flame retardant rating at the custom used thickness of polypropylene insulation sheet 0.125mm～0.75mm.To nitrogen phosphorus compositional flame-retardant, Chinese patent CN 200410052598.5 discloses with homo-polypropylene, Co-polypropylene, phosphoric acid ester, trimeric cyanamide and heat conductive filler blend and has prepared the heat conductive insulating pad, has the mechanical property of fire retardant addition ambassador polypropylene foil and the problem of decreasing insulating equally.
Summary of the invention
The purpose of this invention is to provide a kind of halogen-free flame retarding polymer sheet material,, and satisfy the existing or following green flame-proof environmental protection standard with the solution the above-mentioned problems in the prior art with the feature of environmental protection, high flame retardant and high heat resistance.
The technical scheme that realizes the object of the invention is as follows:
A kind of halogen-free flame retarding polymer sheet material is characterized in that mainly being made by the component of following mass parts:
