Problems solved by technology

Due to poor weather resistance and aging resistance, these foaming materials can only be used in the midsole of shoe materials, and are rarely used in back sheet materials. Moreover, the shoe materials produced by these materials have poor elasticity, poor anti-slip performance, and are prone to aging and cracking, so they can only be produced low end cheap shoes
[0004] However, the shortcomings of TPU, such as high hardness, poor wet resistance, and high density, also hinder its application.
CN101824201A discloses a method for functionalizing SEBS, but when the obtained functionalized SEBS is used for TPU modification, the effect of the modified TPU is not good. On this basis, how to obtain a suitable In-depth research on compatibilizers based on SEBS

Embodiment Construction

[0019] In order to clearly illustrate the technical features of the present solution, the present application will be described in detail below through specific implementation modes.

[0020] The compatibilizer obtained in this application has its own independent use, that is, it is used for TPU shoe materials, so this application is characterized based on the synthesis of TPU shoe materials, but it should be noted that the use of this method is not because the compatibilizer is not a separate product , but because the TPU shoe material is used as an end product, the effect of the compatibilizer on its physical and chemical properties is its ultimate goal.

[0021] The test procedure of this application is carried out according to the following steps:

[0022] 1 Synthesis of compatibilizer

[0023] S1. Blending raw material 1, the components of raw material 1 are shown in Table 1;

[0024] S2. Put the blended raw material 1 into a twin-screw extruder, and perform water ring ...

Abstract

A compatibilizer and its synthesis method as well as the TPU shoe base material containing the same and its synthesis method, including the following raw materials in parts by mass: SEBS interpolymer: 5-15 parts; naphthenic oil: 4-8 parts ; Prepolymer monomer: 0.5-1.5 parts; Initiator: 0.1-0.5 part; Described prepolymer monomer is made up of styrene, acrylic acid, butyl acrylate, and described styrene in prepolymer monomer The mass percentage is not lower than 15%, the mass percentage of the acrylic acid in the prepolymer monomer is not lower than 10%, and the mass percentage of the butyl acrylate in the prepolymer monomer is not lower than 40%. The compatibilizer obtained under the coexistence of styrene, acrylic acid and butyl acrylate in the present application can make the TPU shoe material have better physical and chemical properties. It is speculated that the three-dimensional structure is formed due to the reaction produced in the molding process, and then improves Its wear-resistant and anti-skid performance is improved, and its ductility is greatly improved.

Description

technical field [0001] The application relates to a compatibilizer and a synthesis method thereof, as well as a TPU shoe base material containing the compatibilizer and a synthesis method thereof. Background technique [0002] As we all know, the shoe sole material must have the characteristics of high elasticity, softness, wear resistance, oil resistance, hydrolysis resistance, wet slip resistance, high and low temperature resistance, and folding resistance. At the same time, shoe materials are beginning to be lightweight, which is the basis for this product development. [0003] So far, there are two main types of shoe backsheet materials: rubber and TPU, and other foam materials such as EVA, TPR, TPE, and PVC are also used. Due to poor weather resistance and aging resistance, these foaming materials can only be used in the midsole of shoe materials, and are rarely used in back sheet materials. Moreover, the shoe materials produced by these materials have poor elasticity, ...
