Description

Preparation method of anti-skid rubber composite material for soles

Technical Field

The invention relates to a preparation method of an anti-skid rubber composite material for soles, and belongs to the technical field of anti-skid rubber materials.

Background

The wet skid resistance or skid resistance is one of the most important properties of the sole material, and the value can be expressed by the dynamic friction coefficient and the static friction coefficient of the sole and a wet road surface, and the larger the friction coefficient is, the better the wet skid resistance is. Wet skid resistance is closely related to the safety and comfort of the footwear product.

For rubber for shoes, good anti-skid property is one of the basic functions of rubber products for soles, and is an important index for measuring the quality of shoes. The anti-skid performance of the sole refers to the anti-skid effect or the grip of the sole on the ground, and the quality of the anti-skid performance is directly related to the safety of the shoe when the shoe is worn. The anti-skid performance of the sole is not good, the sole is easy to skid and fall when walking on a wet and slippery and icy road surface, the air temperature is lower in most northern areas in winter, water is easy to accumulate on the road surface to ice, and people can slide more easily when walking on the road surface. In addition, along with the flourishing development of economy and the continuous progress of society, people build the road surface and the indoor ground more and more smoothly, which leads to the frequent occurrence of falling injury accidents, so that the anti-skid performance of the sole material is effectively improved. The anti-skid performance of the sole can be judged by the friction coefficient of the sole and the roadbed. Differences in the anti-slip properties of the sole can be caused for different materials, in different humidity environments, and on different road surfaces. Therefore, when the sole material is manufactured, the influence of various factors on the anti-skid performance of the sole is comprehensively considered, and the anti-skid performance of the sole is improved in a targeted manner according to different purposes of the footwear.

The friction phenomenon is very extensive, and the friction between parts in the same object is generally called internal friction, such as viscosity of fluid and the like; the friction between two objects is called external friction, and the friction can be classified into static friction and dynamic friction according to the state of the object; classifying according to the motion characteristics of the object, and dividing the motion characteristics into sliding friction and rolling friction; classified according to the surface condition of the object, dry friction and wet friction can be classified.

The friction of rubber on a hard and smooth surface is mainly adhesion friction, in the friction process, when the friction speed reaches a certain value, the rubber surface can generate deformation with different degrees, at this time, a separation wave with the surface deformation faster than the friction speed, called as a salad Mach wave, is generated, in the process of forward propagation of the salad Mach wave, the rubber is gradually stretched, peeled and then adhered by the hard rail surface, the friction force changes repeatedly, and the so-called 'stick-slip' vibration phenomenon with the periodic change of the friction force occurs.

In the condition of water wetting, the rubber surface can not be directly in actual contact with the friction substrate surface, and the water film is distributed between the rubber surface and the friction substrate surface to act as a lubricant for lubrication, so that the friction force is reduced sharply. When the thickness of the water film exceeds the height of the protrusions on the surface of the friction substrate, the frictional force between the two interfaces results from the shear stress of the water film between the interfaces. That is to say that when a water film is present between the two frictionally interactive surfaces to act as a lubricant, the frictional force depends solely on the hydrodynamics of the water film, which is also referred to as hydrodynamic lubrication. Rubber-like elastomers, on the other hand, undergo elastic deformations during the course of friction, which, when they play an important role in hydrodynamic lubrication, are referred to as elastohydrodynamic lubrication. The friction force generated between the two contact surfaces is small, and mainly comprises hysteresis loss generated by deformation and viscous resistance of the lubricant.

The friction mechanism of rubber on a polished smooth ice surface is the same as that on other smooth surfaces, and the friction force between two interfaces has a relationship with the viscoelastic property of each rubber.

The two main factors affecting the anti-skid performance of the sole are the sole material and the sole pattern. The sole pattern can influence the anti-skid performance of the sole to a great extent, particularly under the condition that the road surface is lubricated by a water film, the friction coefficient between the sole and the road surface is very low, and the design of the sole pattern is favorable for removing water on a contact surface and increasing the effective contact area between the sole and the road surface.

The sole material has a remarkable influence on the anti-skid performance of the shoe, and the anti-skid performance of the sole material can be changed due to the change of external factors such as pavement materials, pavement roughness, pavement pollutants and the like. When studying the anti-skid performance of the sole, the environmental temperature of the shoe when being worn is taken into full consideration, when designing and producing the anti-skid shoe, the influence of various factors is taken into full consideration, the sole friction coefficient can not be increased by independently considering sole patterns, the anti-skid performance of the sole material is improved by considering the improvement of the composition of the sole material, and particularly, the influence of the composition of the material is paid attention when being used on a special road surface such as an ice and snow road surface. In addition, the hardness of the material also has a certain influence on the anti-skid performance of the sole. However, this effect is not stable and cannot be used as an ideal parameter value for influencing the friction coefficient of the shoe sole.
