Problems solved by technology

However, the disadvantages of rubber soles are not only heavy weight and high cost, but also poor ozone resistance.
Thermoplastics such as thermoplastic polyurethane are valued for their excellent mechanical strength, elasticity, wear resistance and aging resistance, but polyurethane has poor anti-slip properties and is not suitable as a shoe sole material

preparation example Construction

[0129] The preparation method of the modified calcium carbonate of the present invention is: adding deionized water to a certain amount of calcium carbonate to disperse for 30 minutes (ultrasonic assistance can be used to improve the dispersion effect), then heating the system temperature to 60-70°C, adding surface The active agent is stirred and reacted for 2-3 hours, cooled to room temperature, filtered, the filter cake is washed with water, dried and ground to obtain the product.

[0130] Surfactant refers to a substance that can significantly change the interface state of its solution system by adding a small amount. With fixed hydrophilic and lipophilic groups, they can be oriented on the surface of the solution. The molecular structure of the surfactant is amphiphilic: one end is a hydrophilic group, and the other end is a hydrophobic group.

[0131] Still further preferably, the surfactant of the present invention is a silicone surfactant.

Abstract

The invention relates to the technical field of shoe materials, in particular to an antibacterial TPV (thermoplastic vulcanizate) material for nurse shoes. The TPV material is at least prepared from raw materials in parts by weight as follows: 10 parts of EPDM (ethylene propylene diene monomer), 1-3 parts of butadiene rubber, 1-3 parts of polypropylene, 0.1-0.3 parts of graft polypropylene, 4-6 parts of hydrogenated styrene-butadiene block copolymer, 10-15 parts of a softener, 0.1-0.3 parts of a sulfurizer, 0.1-0.3 parts of a vulcanization accelerator, 0-0.1 parts of an antioxidant and 5-10 parts of filler, wherein the filler is barium salt and calcium salt.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to an antibacterial TPV material for nurse shoes. Background technique [0002] Shoes are essential daily necessities for everyone, and the sole, as an important part of shoes, determines the comfort and safety factor of shoes when walking. As for nurses' shoes, since nurses often use some utensils during work, nurses' shoes need to have excellent dry slippery and wet slippery properties to ensure their safety. And in order to ensure the comfort of walking, it needs to have the characteristics of light weight, as well as certain elasticity and extensibility. In addition, since there may be many bacteria in medical places, nurse shoes also need to have properties such as antibacterial. [0003] Rubber is currently the material used in most shoe soles due to its good anti-skid properties, elasticity and extensibility. However, the disadvantages of rubber soles are not only h...
