Problems solved by technology

However, the sucking part and venting part of the pacifier are the key points of the whole product. The flow rate of the sucking part and the air intake of the venting part will affect the normal use of the pacifier. If the flow rate is too high, the baby will not be able to swallow the milk, and its ventilating function Poor, the imbalance of air intake, air outlet and flow will make the internal air pressure of the bottle different from the external air pressure, which will easily cause the nipple to be flattened and unable to discharge water, or the baby will suffer from abdominal distension, abdominal pain, hiccups, and spit-up due to excessive air intake. Therefore, its use effect i...

Abstract

The invention discloses a rubber nipple silica gel material and a preparation method thereof, which belong to the technical field of a silica gel material. The rubber nipple silica gel material comprises the following raw materials: siloxane dimethicone, hydroxyl silicone oil, dimethoxydimethylsilane, gas-phase white carbon black, a platinum catalyst, polylactic acid fiber, casein, and ca bentonite. The preparation method comprises the steps of mixing, injection moulding, and sulfuration and the like. The method employs polylactic acid fiber, casein and ca bentonite as reinforcement, and the service life and physical properties of the rubber nipple silica gel material are increased.

Description

technical field [0001] The invention belongs to the technical field of silica gel products, and in particular relates to a silica gel material for a feeding bottle nipple and a preparation method thereof. Background technique [0002] Natural latex has been used as raw material for infant pacifiers in history. Natural latex is a soft material with a very high elongation at break. It has good elasticity and is easy to return to its original shape after being deformed. The disadvantages of manufactured pacifiers are that they have peculiar smell, are prone to aging, and have a short service life. Therefore, a liquid silicone rubber nipple formed by high-temperature heat vulcanization has appeared. The silicone rubber nipple has the characteristics of no peculiar smell, high temperature resistance, repeated boiling and disinfection, not easy to aging, and long service life. However, the sucking part and venting part of the pacifier are the key points of the whole product. The ...
