[0045] EVA: 65

[0046] NR: 15

[0047] SBR: 15

[0048] CaCO3:4

[0049] Si-69 wear agent: 4

[0050] ZnO: 3

[0051] ZnST: 3

[0052] ST: 1.5

[0053] DCP: 1

[0054] AC: 1.8.

[0055] The preparation method is as follows:

[0056] First mix other raw materials except DCP and AC for banburying, add DCP and AC 5 minutes before the end of banburying, granulate after the end of banburying, and then one-time injection molding to obtain the light weight non-slip and high wear-resistant rubber Material.

[0057] During banburying, control temperature is 125 ℃, banburying time is 18min.

[0058] During one injection molding, the control temperature is 185°C and the time is 4min.

Embodiment 2

[0060] The formula of this embodiment is as follows (note: each raw material is by weight):

[0061] EVA: 60

[0062] NR: 10

[0063] SBR: 20

[0064] CaCO3:5

[0065] AG-209 wear agent: 3

[0066] ZnO: 2

[0067] ZnST: 4

[0068] ST: 2

[0069] DCP: 0.8

[0070] AC: 1.5.

[0071] The preparation method is as follows:

[0072] First mix other raw materials except DCP and AC for banburying, add DCP and AC 4 minutes before the end of banburying, granulate after the end of banburying, and then make the above-mentioned light weight non-slip and high wear-resistant rubber by one injection molding Material.

[0073] During banburying, control temperature is 120 ℃, banburying time is 20min.

[0074] During one injection molding, the temperature is controlled at 180°C and the time is 5 minutes.

Embodiment 3

[0076] The formula of this embodiment is as follows (note: each raw material is by weight):

[0077] EVA: 70

[0078] NR: 20

[0079] SBR: 10

[0080] CaCO3:3

[0081] Si-69 wear agent: 5

[0082] ZnO: 4

[0083] ZnST: 2

[0084] ST: 1

[0085] DCP: 1.2

[0086] AC: 2.

[0087] The preparation method is as follows:

[0088] First mix other raw materials except DCP and AC for banburying, add DCP and AC 6 minutes before the end of banburying, granulate after banburying, and then make the above-mentioned light weight non-slip and high wear-resistant rubber by one injection molding Material.

[0089] During banburying, control temperature is 135 ℃, banburying time is 12min.

[0090] During one-time injection molding, the temperature is controlled at 195°C and the time is 3 minutes.

Abstract

The invention relates to a rubber composite material and particularly relates to a light anti-slipping high-wear-resistance rubber material for a sole and a preparation method thereof. The light anti-slipping high-wear-resistance rubber material for the sole is prepared from the following raw materials in parts by weight: 55-75 parts of EVA (Ethylene Vinyl Acetate), 8-25 parts of NR (Natural Rubber), 8-25 parts of SBR (Styrene Butadiene Rubber), 2-6 parts of CaCO3, 2-6 parts of wear-resisting agent, 1-5 parts of ZnO, 1-5 parts of ZnST, 0.5-2.5 parts of ST, 0.5-1.5 parts of DCP (Dibasic Calcium Phosphate) and 1.2-2.5 parts of AC (Azodicarbonamide). Compared with the prior art, the components and the ratios of all raw materials are optimized and the light anti-slipping high-wear-resistance rubber material has the advantages of light weight, anti-slipping performance and wear resistance under the synergistic effect of the components with the ratios. The light anti-slipping high-wear-resistance rubber material is particularly suitable for manufacturing a light and anti-slipping sneaker sole.

Description

technical field [0001] The invention relates to a rubber composite material, in particular to a light-weight, non-slip and highly wear-resistant rubber material used for shoe soles and a preparation method thereof. Background technique [0002] The comfort level, service life, and special functions of shoes are all related to the performance of sole materials to a large extent. Present sole material is in the majority with rubber. Ordinary rubber soles have the advantages of wear resistance, non-slip, elasticity, and waterproof, but they have the disadvantages of heavy weight, non-slip performance that cannot meet high requirements, and poor shock absorption, which cannot meet the needs of strenuous sports. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of light, non-slip and high wear-resistant rubber material, which is used to make shoe soles and has the characteristics of light weight, wear resist...
