Embodiment 1
[0028] Such as figure 1 As shown, a rubber bottle cap for enteral nutrition emulsion, the inner wall of the bottle cap is provided with an annular rib 2, and the inner wall of the bottle cap is divided into an inner upper wall of the bottle cap and an inner lower wall of the bottle cap by the annular rib 2, Further, the vertical height H2 of the annular rib is 4.8-6.0mm, the vertical height H1 of the inner upper wall of the bottle cap is 2.05-3.5mm, and the vertical height H3 of the inner lower wall of the bottle cap is 5.0-6.4mm .
[0029] The contact angle between the inner upper wall of the bottle cap and the inner top surface 1 of the bottle cap is the fillet R5, and the fillet R5 is 0.5-2.0mm, and the contact angle between the inner lower wall of the bottle cap and the lower end surface of the bottle cap is the fillet R4, and R4 is 0.4 -1.5 mm.
[0030] The diameter of the circumference where the inner lower wall of the bottle cap is located is greater than the diameter...
Embodiment 2
[0034] A method for manufacturing a bottle cap for an enteral nutrition emulsion, the steps are as follows:
[0035] (1) Ingredients: According to the weight fraction, weigh 100 kg of bromobutyl rubber, 40 kg of calcined clay, 0.8 kg of sulfur vulcanizing agent, 8 kg of magnesium oxide, 0.2 kg of carbon black, and kg of titanium dioxide for use;
[0036] (2) Mixing: Add the weighed raw materials bromobutyl rubber, calcined clay, magnesium oxide, carbon black, and titanium dioxide into the internal mixer in sequence, and mix according to the corresponding internal mixing process. The internal mixing time is 10 minutes , Banbury temperature 100 ℃. The rubber material after internal mixing is mixed on the open mill, and the sulfur vulcanizing agent weighed is added to the mixed rubber, and the rubber material mixed on the open mill is rolled into rolls for later use.
[0037] (3) Film output: put the mixed film into the three-roll calender to make a film strip, and then wind the...
Embodiment 3
[0044] A method for manufacturing a bottle cap for an enteral nutrition emulsion, the steps are as follows:
[0045] (1) Ingredients: Weigh 100 kg of bromobutyl rubber, 60 kg of calcined clay, 0.4 kg of sulfur vulcanizing agent, 5 kg of magnesium oxide, and 3 kg of carbon black for use;
[0046] (2) Mixing: Add the weighed raw materials bromobutyl rubber, calcined clay, magnesium oxide, carbon black, and titanium dioxide into the internal mixer in sequence, and mix according to the corresponding internal mixing process. The internal mixing time is 10 minutes , Banbury temperature 100 ℃. The rubber material after banbury mixing is mixed on the open mill, and the sulfur vulcanizing agent weighed is added to the mixed rubber, and the rubber material mixed on the open mill is rolled into rolls for later use.
[0047] (3) Film output: Put the mixed film into the three-roll calender to make a film strip, and then wind the film strip on the rollers of the sixteen-roll cooling machin...
