Problems solved by technology

But at present, there is no oil-resistant and low-temperature-resistant rubber hose inner layer rubber products, most of which are single-standard products, and some are only oil-resistant but do not meet the national safety production standards, so these products basically have the problem of short service life.

Embodiment 1

[0036] In parts by mass:

[0037] Chlorinated polyethylene (CM) 40 parts,

[0038] 60 parts of alloy glue,

[0039] Anti-aging agent 2 parts,

[0040] Semi-reinforced furnace black N774 60 parts,

[0041] 40 parts of modified nano kaolin,

[0042] 2 parts paraffin,

[0043] Cold-resistant plasticizer DOS 30 parts,

[0044] Magnesium oxide 5 parts,

[0045] Fatty acid amides NC 2 parts,

[0046] Two parts of dimercaptothiazole derivative TDD.

[0047] The first step is to put chlorinated polyethylene (CM) rubber, alloy glue and anti-aging agent into the rubber kneader by weight, keep the temperature at 100°C for 5 minutes, and then put magnesium oxide and paraffin into the kneader in turn. Mix the rubber in the kneader for 2 to 3 minutes, then put the modified nano-kaolin, semi-reinforcing furnace black and cold-resistant plasticizer into the kneader and mix the rubber for 4 to 5 minutes, then discharge the rubber, and beat 6 rolls, cooled to below 60°C for use;

Abstract

The invention relates to a formula of inner glue in a chlorinated polyethylene oil-resisting and low-temperature-resisting rubber tube. The formula comprises the following components in parts by weight: 60-80 parts of chlorinated polyethylene (CM), 0-20 parts of alloy glue 4, 1-2 parts of an antiager, 60-90 parts of semi-reinforced furnace black, 40-60 parts of modified nano kaolin, 1-2 parts of wax, 30-45 parts of a cold-resistant plasticizer, 5-8 parts of magnesium oxide, 2-4 parts of fatty acid amide and 2-4 parts of a disulfydryl thiazole derivative. Compared with conventional formula, the formula provided by the invention has the advantages that the cost is lower, the liquid resisting performances of the prepared inner glue completely reach HG / T3037-2008 standard and the prepared inner glue can be used for a long time in a working environment at -50 DEG C.

Description

technical field [0001] The invention relates to rubber hoses, in particular to a chlorinated polyethylene oil-resistant and low-temperature-resistant rubber hose inner layer glue formula and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, especially the rapid development of the oil industry market, oil-resistant hoses are playing an increasingly important role in transporting various oils. [0003] Due to the particularity of transporting oil, especially in the cold northern regions, the rubber hose must not only be resistant to various oils, but also to be resistant to low temperatures. But at present, there is no oil-resistant and low-temperature-resistant rubber hose inner layer rubber products, most of which are single-standard products, and some are only oil-resistant but do not meet the national safety production standards, so these products basically have the problem of short service life...
