Abstract

The invention discloses a butyl rubber stopper for a blood collection tube. The butyl rubber stopper is prepared from the following raw materials in parts by weight: 100 parts of brominated butyl rubber, 10 parts of titanium dioxide, 1 part of carbon black, 4 parts of active magnesium oxide, 4 parts of light magnesium oxide, 0.3 part of sulfur and 80 parts of pottery clay. Compared with a conventional formula, the formula of the butyl rubber stopper has the characteristics that active magnesium oxide is used to replace a vulcanization accelerator, zinc oxide and stearic acid in an original formula, so that the defects that the accelerator is toxic and zinc oxide is easily separated from rubber are overcome, and a butyl rubber stopper product has good chemical and physiologic inertia, good antioxidant activity, good ageing resistance and good heat resistance.

Description

technical field [0001] The invention relates to the technical field of medical rubber stoppers, in particular to a butyl rubber stopper for blood collection tubes. Background technique [0002] Butyl rubber plugs for blood collection tubes are important components of blood collection tubes. The butyl rubber plugs commonly used at present include bromobutyl rubber, titanium dioxide, carbon black, light magnesium oxide, sulfur, clay, vulcanized Accelerators, zinc oxide and stearic acid, among which vulcanization accelerators usually include thiazoles, sulfenamides, thiurams, dithiocarbamates, guanidines, thioureas, aldehyde amines and xanthans Acids, these accelerators all have certain toxicity. In addition, zinc oxide and stearic acid are used as activators in the traditional formula. Zinc oxide is easy to precipitate in the rubber, and the butyl rubber stopper produced is easy to oxidize and puncture chip. Contents of the invention [0003] The purpose of the present inv...
