Embodiment 1

[0025] Prepare the wear-resistant and fold-resistant polypropylene composite shoe sole material according to the following steps:

[0026] (1) Grind the barite with a pulverizer, transfer it to a pulverizer and grind it to a barite powder with an average particle size of 40 μm, wash it repeatedly with deionized water until the filtrate is neutral, then add it into deionized water, and stir it ultrasonically Until the dispersion is uniform, a slurry with a solid phase mass fraction of 4% is obtained, magnesium chloride and hydrofluoric acid are added in sequence, and ultrasonically stirred until the dispersion is uniform, transferred to a colloid mill for grinding for 30 minutes, transferred to an autoclave, and heated to 140°C. Stir and react at a constant temperature for 20 minutes at a speed of 160 rpm, add sodium stearate after pressure relief and continue to stir and react at a constant temperature for 30 minutes, filter after taking out, place in an oven and dry to constan...

Abstract

The invention provides a preparation method of an abrasion-resistant fold-resistant polypropylene composite sole material. The method comprises the following steps that 1, barite is ground into barite powder, washing is conducted, deionized water is added for even dispersion, slurry is obtained, magnesium chloride and hydrofluoric acid are added for even dispersion, grinding is conducted, the mixture is transferred into a high-pressure reaction kettle, heating is conducted, a stirring reaction is conducted, sodium stearate is added, filtration and drying are conducted, and barium sulfate crystal whiskers are obtained; 2, the deionized water is added to the barium sulfate crystal whiskers, constant temperature stirring is conducted to obtain a crystal whisker solution, borate surfactant is added, heating, stirring, cooling, washing, filtering and drying are conducted, and modified barium sulfate crystal whiskers are obtained; 3, polypropylene resin, a plasticizer, a lubricant, a stabilizer, an antioxidant, a foamer, an antibacterial and antifungal agent and the modified barium sulfate crystal whiskers are mixed, the mixture is moved to an internal mixer for internal mixing, transferred to an open mill for mixing and thinning, transferred to pelletizer for pelleting and drying and then transferred to an extruder for extruding, and mold forming is conducted. The sole material prepared through the method is excellent in abrasion resistance and folding resistance.

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a preparation method of a wear-resistant and folding-resistant polypropylene composite shoe sole material. Background technique: [0002] The English name of polypropylene is Polypropylene, abbreviated as PP. It is a crystalline polymer with regular structure. It is a light milky white pellet, odorless, non-toxic, and light-weight thermoplastic resin. The relative density of polypropylene is 0.90-0.91, which is the lightest among general-purpose resins. It has good mechanical properties and good heat resistance. Its melting point is about 170°C. Under no external force, it will not deform at 150°C. It has good chemical stability and is resistant to acids, alkalis and organic solvents. It is compatible with most chemicals (such as fuming nitric acid, Chromic acid solution, halogen, benzene, carbon tetrachloride, chloroform, etc.) have no effect and hardly absorb water. The disadvantage o...
