Problems solved by technology

Traditional pharmaceutical synthetic gaskets are produced from polyisoprene rubber and related auxiliary materials through more than 20 processes such as rubber mixing, vulcanization, tableting, slicing, cold punching, siliconization, and refrigeration. The production process is cumbersome. , time-consuming, and pollute the environment to a certain extent, not only the production cost remains high, but also the product quality cannot be guaranteed, and the phenomenon of acupuncture chip falling occurs from time to time

Embodiment 1

[0015] The raw material formula of this example is: chlorinated butyl rubber 45000g, calcined kaolin 40500g, tert-octylphenol formaldehyde resin 675g, stearic acid 450g, zinc oxide 2250g, modified polyethylene 900g, titanium dioxide 1350g, semi-reinforcing furnace French carbon black 166g and magnesium oxide 60g.

[0016] Present embodiment prepares product according to the following steps:

[0017] (1) Batching and banburying: Mix all kinds of raw materials evenly together, banbury in the banbury mixer for 10 minutes, and the glue discharge temperature is 100°C, and then add it to the XKY-550 rubber open-type rubber mixer for opening Refining, milling operation for 10 minutes, the temperature of the front and rear rolls are 60±5°C and 65±5°C respectively, and finally cooled by the hanger type cooling device, cooled to 25°C, the cooled film is coiled and parked for 5 sky;

[0018] (2) Preforming: Put the film into the feeding port of the cold feed extruder through the guide ...

Abstract

The invention relates to a medicinal packaging material, in particular to a medicinal synthetic spacing piece and a preparation method thereof. The medicinal synthetic spacing piece is characterized by being prepared from the following raw materials: chlorinated butyl rubber, calcined kaolin, tertiary octyl phenol formaldehyde resin, stearic acid, zinc oxide, modified polyethylene, titanium pigment, semi-reinforced furnace treated black and magnesia. The medicinal synthetic spacing piece has the advantages that: (1) a medicinal elastomer is taken as a major raw material, so that production cost is reduced greatly while the physical and mechanical properties required by the spacing piece are ensured; (2) various raw materials used in a formula are free from toxic or side effect, are completely consistent with the standard of medicinal raw materials, are completely environmentally-friendly, and are free from environmental pollution; (3) a production process is simple, energy consumptionis lowered greatly, and production efficiency is increased; (4) procedures are reduced, so that manual error factors are reduced greatly, and the stability of quality is ensured; and (5) product performance is high, and an ecdysis phenomenon is avoided.

Description

technical field [0001] The invention relates to a pharmaceutical packaging material, in particular to a pharmaceutical synthetic gasket and a preparation method thereof. Background technique [0002] Pharmaceutical gaskets are the most commonly used sealing elements in the field of pharmaceutical packaging materials, used to prevent fluid leakage, etc. Traditional pharmaceutical synthetic gaskets are produced from polyisoprene rubber and related auxiliary materials through more than 20 processes such as rubber mixing, vulcanization, tableting, slicing, cold punching, siliconization, and refrigeration. The production process is cumbersome. , consume energy and time, and have certain pollution to the environment, not only the production cost remains high, but also the product quality cannot be guaranteed, and the phenomenon of acupuncture chip shedding occurs from time to time. A low-cost, simple process, safe and environmentally friendly, high-quality pharmaceutical syntheti...
