Description

A kind of water proof fire retardant CABLE MATERIALS and preparation method thereof
Technical field
The present invention relates to CABLE MATERIALS technical field, particularly relate to a kind of water proof fire retardant CABLE MATERIALS and preparation method thereof.
Background technology
Nanotechnology is in the eighties rise in last century, and is widely used in multiple fields.Research finds, adds after nanoparticle in the polymer, can the performance of significantly lift-off material.Such as when adding the nanoparticles such as a small amount of graphite skilful, CNT, molybdenum bisuphide in polymer, the mechanical strength of material will be obviously improved IWI.Research finds, only adds minimal amount of nano material and the HRR of material combustion just can be greatly reduced, the most also can the mechanical strength of lift-off composite.The nano flame retardant system that research is relatively more at present mainly has several: (1) inorganic nano-particle, such as nanometer ammoxidation town, nanometer ammoxidation lead and nano silicon etc..This based flame retardant is relatively low due to himself flame retarding efficiency, and fire retardant mechanism also with other nanoparticle difference, needs bigger addition, therefore can not be classified as flame retardant nano-materials completely when reality is applied.And the filling of filler also can produce impact to the mechanical property of material self.(2) laminated inorganic matter, such as nanoclay, brucite, expansible graphite etc..(3) pipe carbon and acicular nanoparticles, such as CNT, halloysite nanotubes and meerschaum etc..The tenth day of lunar month year in 21 century, the focus nano flame retardant technology having a large amount of report galapectite in recent years about polymer/carbon nano-tube flame-retardant system and meerschaum to be increasingly becoming research occurs two during the last ten years, although gradually growing up and achieve a series of achievement in research, but the polymeric material of nanorize combustion to extensively application, still has very long road to walk from research;
About the application in the polymer of nano flame retardant technology, some problem following is currently mainly had to need to solve: 1. nano fire-retarding additive significant advantage is that in trying for taper calorimetric, HRR reduces for a lot of nanoparticles, it is only necessary to add few amount and just the HRR of material combustion can be greatly reduced by W.But effect is tested significantly for traditional fire-retardant trial work section, such as oxygen index (OI) and vertical combustion, the most also can play negative effect.Therefore, need to consider nanoparticle to be modified or reaches the effect of cooperative flame retardant by compounding use with conventional flame retardant.The most in recent years, nanometer particle-modified research is got more and more, the particularly intercalation modifying to nanoclay.But the intercalation modifying agent of existing frequently-used nanoclay is the burning base amine salt of long-chain mostly, lacks and be specifically designed to flame-retardant modified intercalator or surface modifier.And most modifying agent itself does not have anti-flammability, some self the most flammable;Heat stability is the most poor, and initial decomposition degree is low, and difficulty is applicable to engineering plastics etc. and irons and melt the polymer that temperature is higher.Therefore, it is a direction of future studies for having nanometer particle-modified dose of anti-flammability and heat stability concurrently.3. having clear and definite fire retardant mechanism from the fire retardant such as halogen flame, phosphor nitrogen combustion inhibitor different, present stage lacks the explanation of system to the mechanism of nano flame retardant.Current approved mechanism mainly has the obstruct mechanism of the radical-scavenging mechanism of nanoclay, solid phase;Synergistic catalytic mechanism with expanding fire retardant;The network structure of CNT intercepts the impact etc. in mechanism and combustion process on system rheological characteristic.Therefore, the elaboration for nanoparticle fire retardant mechanism during polymer combustion will be the direction of future studies, and CNT lacks polar functional group due to surface simultaneously, and the compatibility with polymeric matrix is poor;The structure of high length-diameter ratio can cause the winding in the course of processing, gathering, thus is difficult to well disperse.Additionally, CNT only has obvious effect to reduction HRR, but can not effectively put forward oxygen index (OI) and the vertical combustion grade of material.In order to improve the CNT compatibility in the polymer and dispersibility, can use coupling agent, surfactant or polymer etc. that CNT is carried out surface to change, but class method of modifying often difficulty puies forward its fire resistance, some even can destroy original anti-flammability;.
