Addition number be 82 parts, other are constant.
The physical property for the film that above-described embodiment 4-6, comparative example 1-2 are prepared and existing brombutyl material
Rationality can be compared as follows shown in table 1-6.
Table 1
Table 2
Table 3
Table 4
Table 5
Table 6
It summarizes:
It compares discovery respectively by table 1 and table 3, is added after compounded rubber, film air-tightness improves, and Mooney reduces, and adds
Work improves.Other performance gaps are little.In actual production process because the uncontrollable factors such as equipment (equipment sealing problem, zero
The abrasion etc. of part) cause partial material to be lost, it is slightly poor compared with laboratory test data, but still the film than compounded rubber is not added
Performance is good.Table 2 and table 4 demonstrate this rule again.
Discovery is compared by table 5 and with table 3: being increased although being directly added into chlorinated polyethylene rubber elongation in formula
(chlorinated polyethylene rubber itself is polymerized to linear polymer chain, elongation with 1500%), while Mooney, hardness can be made and added
The sulphur in working hour becomes MH and becomes larger, to increase apparatus of load and abrasion, and then increases cost.
It is found by table 6 and being compared with table 4: after directly improving brombutyl number in formula and with (chlorination
Polyethylene rubber, which is blended according to the proportion of 100:60 parts by weight with dioctyl phthalate, to be prepared) haloflex is multiple
It is close to close rubber performance, but cost obviously increases.
