example 1

[0022] Example 1: Put 80g of nitrile rubber (N41) and 20g of rubber-plastic alloy (N7030) into the double-roll mill for masticating, then add 5g of activator zinc oxide, 1g of stearic acid, and anti-aging agents 2, 2, 4 in sequence - Trimethyl-1,2-dihydroquinoline polymer (RD) 1.5g and N-isopropyl-N, phenyl-p-phenylenediamine (4010NA) 1.5g, white carbon black 15g, calcium carbonate 40g, Reinforcing carbon black N330, N550, and N774 are 35g, 35g, and 40g respectively, plasticizer dioctyl sebacate (DOS) 25g, binder AS-885g, and finally add a vulcanizing agent: dipentamethylene tetrasulfide Thiuram (TRA) 3g, accelerator dibenzothiazole disulfide (DM) 1.5g, uniformly mixed on an open mill to obtain a compound rubber, and then vulcanized on a plate at 150°C to obtain a vulcanized rubber, and then the vulcanized rubber was punched After testing its mechanical properties and oil resistance, see Table 1 and Table 4.

example 2

[0023] Example 2: The composition of this example is basically the same as that of Example 1, except that 70g of nitrile rubber (N41) is used instead of 80g of nitrile rubber (N41), and 30g of rubber-plastic alloy (N7030) is used instead of 20g of rubber-plastic alloy (N7030). , the experimental method is consistent with Example 1.

example 3

[0024] Example 3: The composition of this example is basically the same as that of Example 1, except that 60g of nitrile rubber (N41) is used instead of 80g of nitrile rubber (N41), and 40g of rubber-plastic alloy (N7030) is used instead of 20g of rubber-plastic alloy (N7030). , the experimental method is consistent with Example 1.

Abstract

The invention discloses an oil-resistant rubber material without free-state sulfur, and relates to a rubber material. Adopted matrix rubber is mixed rubber of nitrile rubber (N41) and rubber alloy (N7030), an adopted sulfuration system is sulfur-carrier thiuram (TMTD or TRA) sulfuration agents without elemental sulfur, adopted sulfuration accelerators are sulfenamide (CZ) or thiazoles (DM), adopted anti-aging agents are amine (RD and 4010NA) anti-aging agents, adopted fillers are one or two kinds of CaCO3, talcum powder and spraying carbon black, adopted reinforcing agents are a mixture of N330, N550 and N774, adopted plasticizers are ester plasticizers (DOS), and a binding system is a mixture of novel binding agents (AS-88) and white carbon black (WCB). According to the oil-resistant rubber material, as sulfur carriers are used as the sulfuration agents, the prepared rubber material is good in oil resistance, does not contain the free-state sulfur, and is more environmentally friendly accordingly, and various properties can meet the national oil resistant rubber pipe standard.

Description

technical field [0001] The invention relates to a rubber material, in particular to an oil-resistant rubber material without free sulfur. Background technique [0002] According to PetroChina and Sinopec's improvement of gasoline standards for vehicles (National V standard), PetroChina and Sinopec require the sulfur content in gasoline to be below 10ppm. In the market, gasoline can meet the standard, but after the gasoline is transported through the oil-resistant rubber hose, the sulfur content seriously exceeds the standard, which is about three times higher, and this situation occurs in both domestic and foreign rubber hoses. In response to the above situation, many researchers use peroxide as a vulcanizing agent to vulcanize oil-resistant hose rubber materials. However, the peroxide vulcanization temperature is high, the vulcanization time is long, and the vulcanizate is difficult to bond with the steel wire skeleton material, so it is difficult to meet the needs of fact...
