Preparation method of high-toughness silicone nipple

Abstract

The invention belongs to the technical field of nipples, and particularly relates to a preparation method of a high-toughness silicone nipple. The method concretely comprises the following steps of (1) weighing raw materials according to the parts by weight; (2) mixing liquid silicone rubber, amino silicon oil, gallic acid, Pulullan, sodium caseinate and sodium carboxymethylcellulose, stirring through a stirrer, and freezing in a freezing tank, so as to obtain a primary mixture; (3) mixing the primary mixture, Arabic gum and water, stirring through the stirrer, and magnetizing in a magnetic field, so as to obtain a secondary mixture; (4) putting the second mixture into a vacuum kneading machine, and vacuum kneading, so as to obtain a mixture; (5) injecting the mixture into a mould throughan injection moulding machine, moulding, and cooling, so as to obtain the high-toughness silicone nipple. The tensile strength, the tearing strength, the elongation and the resilience rate of the nipple are effectively improved, so that the nipple has higher toughness, the damage rate and the tearing rate of the nipple are effectively reduced, the service life of the nipple is prolonged, and the nipple is safe, health and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of pacifiers, in particular to a method for preparing a high-toughness silicone pacifier. Background technique [0002] At present, the baby pacifiers on the market are divided into two types according to the material, which are mainly latex and silica gel; latex pacifiers are generally light yellow in color, and the main material is natural latex, which is a soft and extremely elastic material that can resist pulling. It will not accumulate static electricity and is harmless to the environment. However, since latex is a natural material, it may produce rubbery smell, short service life, and easy aging. Inferior latex will produce toxins at high temperatures; silicone pacifiers are made of food-grade silicone This material has a smooth and transparent surface, is non-toxic and tasteless, and can resist drastic changes in ambient temperature and can be boiled, but its toughness is not as good as latex, and it...

[0002] At present, the baby pacifiers on the market are divided into two types according to the material, which are mainly latex and silica gel; latex pacifiers are generally light yellow, and the main material is natural latex, which is a soft and extremely elastic material that can resist pulling. It will not accumulate static electricity and is harmless to the environment. However, since latex is a natural material, it may produce rubbery smell, short service life, and easy aging. Inferior latex will produce toxins at high temperatures; silicone pacifiers are made of food-grade silicone This material has a smooth and transparent surface, is non-toxic and tasteless, and can resist drastic changes in ambient temperature and can be boiled, but its toughness is not as good as latex, and it is easy to tear once the surface is damaged; therefore, it is urgent to invent a High tenacity silicone nipple
