Background technology
Defeated air flexible pipe is mainly made up of inner glue layer and outer glue-line, mainly in the conveying gas such as air, oxygen, is widely used in the field such as industry, pharmaceutical sector.
Summary of the invention
The technical problem to be solved is to provide the preparation method of the outer glue-line of the good defeated air hose of a kind of elastic performance.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
It comprises the following steps:
The most by weight, 100 parts of ethylene propylene diene rubbers, 6 parts～10 parts of nanometer grade silicas, 0.1 part～0.2 part of silicone oil, 1 part～2 parts of tetraethylthiuram disulfides, 5 parts～10 parts of 2 mercapto benzimidazoles, 20 parts～30 parts of dioctyl esters, 0.1 part～0.2 part of sulfur, 15 parts～20 parts of strong powder of magnesium and 15 parts～20 parts of paraffin are put into banbury and are carried out banburying, banburying terminate after binder removal under conditions of glue temperature is 160 DEG C again, prepare masterbatch；
B. prepared masterbatch is put into mixing roll, adds 15 parts～20 parts of Petropols, 5 parts～10 parts of polyurethanes, 1 part～5 parts of sodium hexameta phosphate, 6 parts～10 parts of sodium pyrophosphates and 6 parts～10 parts of sodium tripolyphosphates, carry out mixing, prepare elastomeric compound；
C. prepared elastomeric compound is put into extruder, make rubber tube blank, and carry out vulcanizing treatment.
Owing to using technique scheme, there is advantages that
The present invention mainly carries out changing surname by adding the Petropols of special ratios, polyurethanes, sodium hexameta phosphate, sodium pyrophosphate, sodium tripolyphosphate and nanometer grade silica in rubber, thus improves its elastic performance.
