AI Technical Summary

Problems solved by technology

Nipples made of high-temperature heat-vulcanized silicone rubber compound also have some problems: the formula of the compound is difficult to adjust, and it is prone to yellowing, which affects the appearance and transparency of the nipple; the product needs secondary vulcanization to eliminate residual vulcanizing agent Odor from pyrolysis
However, in order to ensure that the tear resistance, stretch resistance and resilience of the pacifier meet the actual use, the hardness of the pacifier products is mostly (Shore A) 40-50 degrees, which is quite different from the texture of the mother's breast.

Abstract

The invention discloses a female breast simulated polyethylene composite material. The material is prepared from, by weight, 100-150 parts of polyethylene, 12-17 parts of polypropylene, 8-15 parts of guar gum, 7-10 parts of ferric chloride aqueous solution, 0.6-1.2 parts of 3,3'-oxoindole and 0.1-0.4 part of 2,4-difluorobenzoic acid. The invention further discloses a method for preparing the female breast simulated polyethylene composite material and application of the female breast simulated polyethylene composite material to materials of infantile pacifiers or teats. The composite material is high in female breast texture simulation degree, excellent in tear resistance, stretch resistance and rebound resilience and appropriate in softness and is a great substitute for silicon rubber or rubber and high in market promotion potential.

Description

[0001] Technical field: [0002] The invention relates to the field of composite material processing, in particular to a breast milk simulated polyethylene composite material. [0003] Background technique: [0004] The material used to make baby pacifiers has historically been natural latex. Natural latex is a very elastic and soft material with very good elasticity, easy to return to its original shape, and it is not harmful to the environment. However, the disadvantage of natural latex baby pacifiers is that they are easy to age and have a short service life. Then there were silicone rubber nipples that included high-temperature heat-vulcanized silicone rubber compounds and addition-type liquid silicone rubber. Silicone rubber nipples have the characteristics of high temperature resistance, can be boiled repeatedly, are not easy to age, and have a longer service life. Nipples made of high-temperature heat-vulcanized silicone rubber compound also have some problems: the fo...
