Problems solved by technology

But the plasticizer itself is very easy to cause baby allergy, and because the plasticizer contains phthalates in the environmental estrogen, it is easy to form pseudohormones, affect the hormone content in the body, and then interfere with the original mechanism of endocrine, which will cause endocrine out of balance

Abstract

The invention discloses a baby product TPE (Thermoplastic Elastomer) and a preparation method of the baby product TPE, and solves the problems that: adding a plasticizer in the TPE material causes baby allergies easily, and as the plasticizer contains phthalate ester in environmental estrogen and forms pseudo-hormone easily, the hormone content in the body is affected, the original mechanism of internal secretion is further disturbed and the endocrine dyscrasia of a baby is caused. The key point of the technical scheme is as follows: the material of the baby product TPE comprises the following components by mass: 20-40 parts of SEBS (Styrene Ethylene Butylene Styrene block copolymer), 50-60 parts of cosmetics grade white oil, 5-15 parts of shell powder, 5-15 parts of polyolefin, 5-10 parts of a compatilizer, 0.5-1.5 parts of a slipping agent, 0.1-0.3 part of an antioxygen, 0.1-0.2 part of an antiaging agent and 0.1-0.5 part of an antibacterial agent, no plasticizer is added, and the condition that the allergy of the baby skin is caused by the addition of the plasticizer is avoided.

Description

technical field [0001] The invention relates to baby products, in particular to a TPE for baby products and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to the materials and feel of products used in daily life. In order to protect people's health, a large number of daily necessities that come into contact with the skin are replaced by non-toxic materials. In particular, babies' skin is delicate and prone to allergies. Therefore, parents attach great importance to the selection of baby utensils. [0003] Existing baby utensils are all made of plastics in order to prevent from falling, such as cribs, baby bowls, baby spoons, baby shower caps and the like. However, in order to improve the performance of plastic products, most manufacturers will add plasticizers to plastic products to increase the softness and ductility of plastic products and facilitate processing. But the plasticizer ...
