Abstract

The invention discloses a formula for an oil-resistant rubber plug. The oil-resistant rubber plug is prepared from, by mass, 100 parts of natural rubber, 45-55 parts of filling agents, 5-10 parts of silicon dioxide hydrate, 2-4 parts of titanium dioxide, 0.4 part of semi-reinforcing furnace black, 1-2 parts of stearic acid, 1-2 parts of petroleum jelly for medical purposes, 1-2 parts of dimethyl silicone oil, 3-5 parts of zinc oxide, 2-3 parts of alkylphenol disulfide and 2-4 parts of p-tert-octylphenolic curing resin. Compared with the prior art, the oil-resistant rubber plug prepared through the formula has good air tightness and oil resistance, can be used for sealing oil preparation medicine and meet the air tightness requirements of medicine sealing and the compatibility with the medicine, and is good in oil resisting property.

Description

technical field [0001] The invention relates to an oil-resistant rubber plug formula Background technique [0002] With the rapid development of modern science and technology, various types of drugs emerge in an endless stream, so there are also differentiated requirements for rubber stoppers required for packaging drugs. Oil-based medicines not only have conventional airtightness and compatibility requirements for rubber stoppers, but also require rubber stoppers to have excellent oil resistance, so as to avoid oily medium damage due to long-term contact between rubber stoppers and oil-based medicines. The soluble compounding agent is extracted from the rubber compound, which leads to a sharp decline in the performance of the rubber plug and affects the sealing effect. Contents of the invention [0003] The purpose of the present invention is to provide a formula for oil-resistant rubber plugs, aiming at the packaging requirements of oil-based medicines, and solving the ...
