Abstract

：

Brominized

butyl

rubber

(BIIR)

is

butyl

rubber

(IIR)

of

the

modified

products,

brominated

began

its

research

and

development

in

the

1950s,

the

purpose

is

to

improve

the

performance

and

improve

its

IIR

vulcanized

rubber

and

compatibility

with

other

。

petrochemical company builds at present only a IIR production outfit annual production capacity

is

30,000

t,

but

can

only

produce

ordinary

IIR

products.

China

is

expected

to

2011

IIR

consumption will reach about 27 million t, including halogenating butyl rubber (XIIR) demand will

reach about 20 million t, China (including XIIR IIR) production development prospects.

Brominized butyl rubber main preparation methods of dry mixing method and solution of the

two dry mixing method is developed in the open refined machine will brominized butyl rubber

were

thermal

refining,

brominated

agent

of

bromine

and

butyl

rubber,

generating

brominized

butyl rubber, solution method steps to dissolve and brominized, and washing, solvent exchange

and product recycling

。

Not only keep the BIIR IIR original permeability, low and high attenuation,

characteristics, but also adds to the ordinary IIR possesses the characteristics of sulfiding agent,

and speed, Use all sorts of sulfiding agent vulcanization, With natural rubber (NR), butylbenzene

rubber (SBR), NBR (NBR) and neoprene (CR)

；

and etc. BIIR itself and other rubber vulcanization

good

is

poorer;

IIR,

Excellent

than

IIR.

Brominized

is

mainly

used

in

溴化丁基橡胶的简介

丁基橡胶（

IIR

< br>）由异丁烯和少量异戊二烯共聚而成

,

不饱和度低。

IIR

具有很多优异性能

,

如

低气透性、

良好的热稳定性、

优异的抗臭氧和抗化学腐蚀性、

高阻尼性及卓越的减震性能等

[1]

。但普通

IIR

的硫化速度较 慢

,

与高不饱和橡胶相容性差

,

自粘性和互粘性不好。卤化丁基

橡胶

( HIIR)

是

IIR

的改性产物

,

包括氯化丁基橡胶

（

CIIR

）

和溴化丁基橡胶

（

BIIR

）

。
