Baby product TPE (Thermoplastic Elastomer) and preparation method of baby product TPE

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 ...

Examples

Embodiment 1

[0045] (1) After mixing 20 parts of SEBS and 0.05 parts of antioxidant, uniformly heat up to 100°C and keep it warm for 2 hours;

[0046] (2) Add 50 parts of cosmetic grade white oil to SEBS heated to 100°C, and stir at a low speed of 100r / min until SEBS completely absorbs the white oil;

[0047] (3) SEBS, 5 parts of shell powder, 5 parts of random copolymerized polypropylene, 5 parts of compatibilizer A, 0.5 part of slip agent A, 0.05 part of antioxidant, 0.05 part of antioxidant Blend 0.1 part of aging agent and 0.1 part of antibacterial agent in a high mixer at 1500r / min for 2 minutes until uniformly mixed;

[0048] (4) The material mixed in step (3) is added into a twin-screw extruder with a length-to-diameter ratio of 48:1 for melt extrusion and granulation to obtain a TPE material for manufacturing baby shower caps.

Embodiment 2

[0050] (1) After mixing 40 parts of SEBS and 0.15 parts of antioxidant, evenly heat up to 100°C and keep it warm for 2 hours;

[0051] (2) Add 60 parts of cosmetic grade white oil to SEBS heated to 100°C, and stir at a low speed of 200r / min until SEBS completely absorbs the white oil;

[0052] (3) SEBS, 15 parts of seashell powder, 15 parts of random copolymerized polypropylene, 10 parts of compatibilizer B, 1.5 parts of slip agent B, 0.15 parts of antioxidant, 1.5 parts of slip agent B, 0.15 parts of antioxidant Blend 0.2 parts of aging agent and 0.5 parts of antibacterial agent in a high mixer at 800r / min for 3 minutes until uniformly mixed;

[0053] (4) The material mixed in step (3) is added into a twin-screw extruder with a length-to-diameter ratio of 48:1 for melt extrusion and granulation to obtain a TPE material for manufacturing baby shower caps.

Embodiment 3

[0055] (1) After mixing 30 parts of SEBS and 0.1 part of antioxidant, evenly heat up to 100°C and keep it warm for 2 hours;

[0056] (2) Add 55 parts of cosmetic grade white oil to SEBS heated to 100°C, and stir at a low speed of 150r / min until SEBS completely absorbs the white oil;

[0057] (3) SEBS, 10 parts of shell powder, 10 parts of high-density polyethylene, 7 parts of compatibilizer C, 1 part of slip agent C, 0.1 part of antioxidant, anti-aging 0.15 parts of antibacterial agent and 0.25 parts of antibacterial agent were blended for 2 minutes in a high mixer at 1200r / min until uniformly mixed;

[0058] (4) The material mixed in step (3) is added into a twin-screw extruder with a length-to-diameter ratio of 48:1 for melt extrusion and granulation to obtain a TPE material for manufacturing baby shower caps.
