preparation example Construction

[0027] The present invention provides a kind of preparation method of composite response foam rubber-plastic shoe sole, comprises the following steps:

[0028] After mixing the low-hardness rubber compound with the high-hardness rubber compound, vulcanization and foaming are carried out, and the foaming ratio is (1.2-1.3): 1.1 to obtain foamed rubber; the low-hardness rubber compound and the high-hardness The melt index of the compounded rubber is between 2.5-3g / 10min;

[0029] The foamed rubber is combined with the midsole semi-finished product to obtain a composite responsive foamed rubber and plastic shoe sole.

[0030] The shoe sole prepared by the method of the invention has multiple hardnesses, can adaptively perform different functions under different exercise intensities or road surface environments, and can meet various response requirements in a multi-point bearing manner.

[0031] see figure 1 , figure 1 It is a process flow diagram for preparing shoe soles in so...

Embodiment 1

[0059] Weighing: (1) According to the low-hardness formula, the plastic main materials such as EVA7360M, OBC 9107, SEBS YH506, BIIR X2, BR9000 were weighed as the first group, and stearic acid, zinc stearate, zinc oxide, PIB, Wear-resisting agent is named for the second group; BIBP and foaming agent are named for the third group. (2) According to the high hardness formula, EVA 7470M, POE8003 9107, EPDM 5565, BIIRX2, BR9000 and other plastic main materials are weighed as the fourth group, and stearic acid, zinc stearate, zinc oxide, PIB, wear-resistant agent It is called for the fifth group; BIBP and blowing agent are called for the sixth group. See Table 1 for the specific formulation.

[0060] Mixing: (1) First pour the first group of materials into the internal mixer, and turn on the machine, and pour the second group of materials when the temperature rises to 80-85 degrees; when the temperature rises to 90-95 degrees, pour Add the third group of materials, and pour out th...

Abstract

The invention provides a composite response foaming rubber-plastic sole and a preparation method and application thereof. The method comprises the steps that a low-hardness mixed rubber material and ahigh-hardness mixed rubber material are mixed and then subjected to vulcanization foaming, the foaming ratio is (1.2-1.3):1.1, and foaming rubber is obtained, wherein the melt indexes of the low-hardness mixed rubber material and the high-hardness mixed rubber material are both 2.5-3 g/10min; and the foamed rubber is combined with a midsole semi-finished product to obtain the composite response foamed rubber-plastic sole. The sole disclosed by the embodiment of the invention has two hardness and two colors on a same outsole, has the functions of shock absorption, high elasticity, softness andsupporting performance, and can display different function feedback at each area point of the sole. Under different exercise intensities or road surface environments, the shoe sole material areas with different hardness self-adaptively play different functions, the requirement of intelligent response is met in a multi-point bearing mode, and the exercise experience of consumers is improved.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a composite responsive foamed rubber and plastic sole, a preparation method thereof and sports shoes. Background technique [0002] Under normal circumstances, for the sake of convenience, people rarely make too many requirements for the type of road surface when running. Most runners generally choose to exercise on the streets near their homes, and most of the streets are concrete cement roads, asphalt roads, brick roads, dirt roads and other road surfaces, and it is inevitable that they will encounter unevenness and sand. , small gravel, slippery road, smooth road and other complex road environments. When athletes face various complex road environments, they often need to make slight adjustments to their running style and posture. Especially when running on uneven roads, the unevenness of the road will put more pressure on the knees, and running on uneven roads for ...
