Abstract
The invention discloses a kind of co-polymer foamed material of brominated isobutylene p-methylstyrene and preparation method thereof, its formula includes BIMSM100 parts, 0 100 parts of filler, 0 30 parts of plasticizer, 2 15 parts of foaming agent, 05 parts of activating agent, 05 parts of vulcanizing agent；05 parts of accelerator；05 parts of antioxidant, and preparation method is provided with above-mentioned formula.It the method can be widely used in the fields such as heat-barrier material, encapsulant, insulation material, buffering spacer, sound absorbing plate, medical material utensil, Aero-Space.
Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of brominated isobutylene-p-methylstyrene is co-polymer foamed
Material and preparation method thereof.
Background technology
According to《Chinese high molecular foam material industry production need to be predicted looks forward to the prospect with Development-Pattern Transformation analysis report》Data display,
During 2008 second half year to 2009 first half of the year, influenceed by global financial crisis, certain downslide occurs in domestic economy,
Associated outlet trade is a greater impact, and flexible foamed materials industry development speed slows down.Market scale in 2008 is 54.83
Hundred million yuan, increase by 11.58% on a year-on-year basis, market scale is 61.19 hundred million yuan within 2009, and year-on-year growth rate is 11.60%, is compared
The first two years, there is different degrees of decline.Since the second half year in 2009, global economy started recovery, domestic family
The development of the relevant industries such as electricity, electronic product and Leisure Sport starts slowly to recover the development speed before financial crisis.In advance
Meter is after 2010, and the flexible foamed materials industry of China will have lasting fast development, it is contemplated that annual growth will exceed
15%, it is up to 10,000,000,000 yuan to market scale in 2012.
Brominated isobutylene-p-methylstyrene copolymer has disordered structure, this be due to monomer reactivity ratio it is basic
It is identical.After aggregated and subsequent bromination, some of p-methylstyrene groups are converted into active brominating methyl styrene
Group.In the polymer of these main chain saturations containing isobutene, the p-methylstyrene of 1%-5% mol ratios and
The brominated p-methylstyrene of 0.5%-1.3% mol ratios.Its glass transition temperature or second order transition temperature are with to methylbenzene
The increase of ethylene contents and raise, typically about -57 DEG C.
It was found from from the structure of BIMSM elastomers, carbon-to-carbon double bond is free of in its main chain, C-C crosslinkings can be formed and be good for,
And main chain is saturation, so its heat resistance and ozone resistance are greatly enhanced.This glue does not contain age resistor, oligomeric
