Embodiment 1

[0045] A kind of TPR sole, its raw material composition is as shown in table 1 by weight parts.

[0046] Among them, naphthenic oil is used as the softener, titanium dioxide is used as the filler, gum rosin is used as the resin, dicumyl peroxide is used as the crosslinking agent, antioxidant SP is used as the antiaging agent, and magnesium stearate is used as the lubricant.

[0047] Such as figure 1 Shown, the preparation method of this TPR sole comprises the following steps:

[0048] S1, preparation of masterbatch: plasticize butadiene rubber and anti-aging agent SP through a two-roller plastic mixer at room temperature, take it out for later use; raise the temperature of the two-roller plastic mixer to 150-160°C, melt polystyrene and add plastic The cis-butadiene rubber after mixing is homogeneously lowered to obtain the masterbatch;

[0049] S2, mixing: continue to put the masterbatch, SBS, titanium dioxide, gum rosin, dicumyl peroxide, magnesium stearate and zinc glycero...

Abstract

The invention discloses a TPR (thermoplastic rubber) sole and a preparation method thereof. The TPR sole is prepared from, by weight, 100-120 parts of SBS (styrene butadiene styrene); 8-10 parts of polystyrene; 6-8 parts of butadiene rubber; 35-40 parts of a softening agent; 5-7 parts of a filler; 6-8 parts of resin; 4-6 parts of a cross-linking agent; 1-2 parts of an anti-aging agent and 4-5 parts of a lubricant. The polystyrene and the SBS have good compatibility, the hardness, wear resistance, tear resistance and flowing property of the SBS can be improved, and the shear strength is enhanced. The butadiene rubber has the advantages of regular molecular chain, low hysteresis and heat generation amount, high elasticity, high wear resistance and high low temperature resistance, and the butadiene rubber and the SBS have the advantages of same soft segment B polarity, similar structure and favorable compatibility. The butadiene rubber is added into the SBS / PS rubber, so that the wear resistance, the flexing resistance and the low-temperature resistance of the TPR can be effectively improved, the TPR sole is comfortable to wear in a very cold place and cannot be hardened due to low temperature, the butadiene rubber is added, the heat generated by the TPR shoe under severe conditions is reduced, and the service life of the TPR shoe is prolonged.

Description

technical field [0001] The invention relates to the technical field of shoe materials, more specifically, it relates to a TPR shoe sole and a preparation method thereof. Background technique [0002] TPR material is a thermoplastic rubber material. TPR soles are generally a polymer material modified by blending thermoplastic elastomer SBS and other functional additives. It is formed after extrusion, injection, molding and other processes. Strong bending, good air permeability, strong bonding strength and other advantages. [0003] The Chinese patent whose publication number is CNA discloses a kind of preparation method of high anti-bending SBS composite shoe sole material, and its steps are as follows: (1) dissolving polypropylene mesh fibers in toluene, placing them in an ultrasonic oscillator to oscillate and remove the polypropylene mesh After 2 hours, take out the oil stains and impurities on the surface of the fibrous fiber, wash it with deionized water, dry it in an o...
