preparation example Construction

[0041] The preparation method of the above-mentioned SEBS composite material for slippers of one embodiment, comprises the following steps:

[0042] S10: Mix SEBS, white oil, lubricant, antioxidant and ultraviolet absorber in proportion to obtain a mixture.

[0043] S20: Add the mixture into the internal mixer for the first internal mixing, and then add the foaming agent for the second internal mixing.

[0044] Specifically, the mixture in step S110 is added to the internal mixer at 110°C-120°C for the first time, and after 5-10 minutes, when the temperature rises to 130°C-160°C, a foaming agent is added for the second time. For the second banburying, the time for the second banburying is 1-8 minutes.

[0045] S30: extrude the mixed material after banburying in a single-screw extruder.

[0046] The mixed material after banburying in step S20 is extruded in a single-screw extruder, wherein,

[0047] It should be noted that step S10 and step S20 may also be performed simultan...

Embodiment 1

[0052] (1) 40 parts of SEBS with a weight-average molecular weight of 90,000, 20 parts of white oil, 5 parts of zinc stearate, 5 parts of stearic acid, 5 parts of oleic acid amide, 1 part of antioxidant 1010, and 1 part of ultraviolet absorber were prepared. Mixed to obtain a mixture, and the mixture was added to an internal mixer at 110 ° C for the first internal mixing. After 5 minutes, 3 parts of azodicarbonamide were added, and the second internal mixing was carried out at 140 ° C. The time is 5 minutes.

[0053] (2) The mixed material after banburying is extruded through a single-screw extruder at 210°C, and the average particle size of the pellets obtained by extrusion is about 25 mm.

[0054] (3) Putting the extruded pellets into an injection molding machine for one-time molding to obtain slippers, wherein the injection molding temperature is 220°C.

[0055] Wherein, the preparation method of SEBS is:

[0056] (1) Under the protection of high-purity nitrogen, 500g of cy...

Embodiment 2

[0061] (1) 40 parts of SEBS with a weight-average molecular weight of 200,000, 20 parts of white oil, 5 parts of zinc stearate, 5 parts of stearic acid, 5 parts of oleic acid amide, 1 part of antioxidant 1010, and 1 part of ultraviolet absorber were prepared. Mixed to obtain a mixture, and the mixture was added to an internal mixer at 110 ° C for the first internal mixing. After 5 minutes, 3 parts of azodicarbonamide were added, and the second internal mixing was carried out at 140 ° C. The time is 5 minutes.

[0062] (2) The mixed material after banburying is extruded through a single-screw extruder at 210°C, and the average particle size of the pellets obtained by extrusion is about 25 mm.

[0063] (3) Putting the extruded pellets into an injection molding machine for one-time molding to obtain slippers, wherein the injection molding temperature is 220°C.

[0064] Wherein, the preparation method of SEBS is:

Abstract

The invention relates to a SEBS (Styrene-Ethylene-Butylene-Styrene) composite material for slippers as well as a preparation method and application thereof. The SEBS composite material for slippers isprepared from the following components in parts by mass: 40 to 80 parts of SEBS, 10 to 30 parts of white oil, 3 to 20 parts of lubricant, 0.5 to 2 parts of antioxidant, 0 to 3 parts of ultraviolet absorbent and 2 to 5 parts of foaming agent. The SEBS composite material for slippers as well as the preparation method and application thereof not only has high elasticity, but also improves the problem of poor elasticity of a traditional SEBS composite material for slippers, and has greatly-improved comfort and a wide market prospect. Moreover, slippers can be made by one-time injection molding.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a SEBS composite material for slippers and a preparation method and application thereof. Background technique [0002] Usually, the materials used to manufacture shoes are mainly ordinary rubber, TPR thermoplastic rubber, PU polymer polyurethane synthetic materials. In addition, SBS or SEBS are usually used to make shoes. Generally, SEBS is mixed with other rubber materials to make shoes, and the elasticity of such shoes is not enough to meet the requirements of people on the elasticity of shoes, especially furniture slippers. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a SEBS composite material for slippers and a preparation method and application thereof for the problem of how to improve the elasticity. [0004] A SEBS composite material for slippers, comprising the following components calculated in parts by mass: [000...
