Problems solved by technology

Although the short-fiber composite rubber material produced by this patent has good wear resistance and anti-skid performance, the total amount of carbon fiber and glass fiber added in Examples 1-3 accounted for 15%, 9%, and 15% of the mass of the rubber compound respectively. , it can be seen that the addition of carbon fiber and glass fiber is relatively large, and there is a problem of greatly increasing the processing cost; and glass fiber is heavier than carbon fiber, and when the addition is large, it will directly increase the weight of the shoe, thus affecting shoe comfort

Embodiment 1

[0045] Preparation of fiber pellets:

[0046] Add 5.5g of zinc dimethacrylate, 0.25g of azobisisobutyronitrile and 0.05g of dodecanethiol to 250mL of ethanol, heat to 70°C for 3 hours, add 1g of basalt fiber after the reaction, and recover ethanol by distillation under reduced pressure. The distillation residue was dried at 70°C, crushed into particles, and calcined at 450°C for 3 hours to obtain fiber particles with an average particle size of 150 μm.

[0047] Preparation of rubber fiber composites:

[0048] (1) Add 680g styrene-butadiene rubber, 320g EPDM rubber, 250g carbon black N220, 20g rubber accelerator DZ, 10g rubber accelerator BZ, 20g anti-aging agent 4010NA, 20g dispersant FS-12 and 15g of sulfur, after mixing, add 100g of fiber particles, continue mixing, after the mixing is completed, the film is released to obtain a mixed film with a thickness of 0.5mm;

[0049] (2) Punch the mixed rubber sheet along the calendering direction to obtain a molded rubber sheet, s...

Embodiment 2

[0051]The difference between Example 2 and Example 1 is that the amount of fiber particles is adjusted to 80 g when the rubber fiber composite material is prepared.

Embodiment 3

[0053] The difference between Example 3 and Example 1 is that an additional 15 g of bistrifluoromethanesulfonimide was added as a tackifier during the preparation of the rubber fiber composite.

Abstract

The invention discloses a light antiskid rubber fiber composite material for outdoor shoe sole processing. The light antiskid rubber fiber composite material is prepared from the following raw materials in parts by weight: 60-80 parts of butadiene styrene rubber, 20-40 parts of ethylene propylene diene monomer, 10-30 parts of carbon black, 5-20 parts of fiber particles, 1-5 parts of a rubber accelerator, 1-5 parts of an anti-aging agent, 1-5 parts of a dispersing agent and 1-5 parts of sulfur. The butadiene styrene rubber and the ethylene propylene diene monomer are used as rubber components,a filler and auxiliary agents are added, and meanwhile, micro bulges are formed in the finally prepared rubber fiber composite material by adding the self-made fiber particles, so that the existence of the micro bulges does not influence normal walking of a wearer, but can play excellent wear-resistant and anti-skid properties.

Description

Technical field: [0001] The invention relates to the technical field of rubber materials, in particular to a lightweight non-slip rubber fiber composite material for outdoor shoe sole processing. Background technique: [0002] Anti-skid is the most basic performance requirement for shoes, and good anti-skid performance is the key factor to ensure the safety of the wearer. For outdoor hiking shoes, the requirements for the anti-skid performance of the soles are more stringent. Factors affecting the anti-skid performance of soles include normal load, contact area, static contact time, sliding speed, rubber hardness, surface roughness, viscoelasticity, temperature, surface dry and wet pollution status, etc., and the influence of these factors on the friction coefficient is not isolated, but interconnected. [0003] At present, the anti-skid performance of many shoes on the dry interface can basically meet the anti-skid safety requirements of shoes, but the anti-skid performan...
