Embodiment 1

[0088] Embodiment 1, the preparation of the outsole of anti-seawater corrosion aging

[0089] The formulations are shown in Table 1.

[0090] 1) Mix, vulcanize, and granulate the rubber according to the formula ratio, and set aside;

[0091] 2) Put the material evenly in the rubber mold, and press the middle plate of the mold for 10 seconds;

[0092] 3) Open the middle plate of the mold and cover it with 0.15mm thick high-temperature-resistant nylon fine-grain cloth, close the mold and press it, exhaust once every 10s, and close the mold for 5min after exhausting 3 times, the curing temperature is 160±5°C, the pressure 80MPa;

[0093] 4) Open the mold after vulcanization, gently tear off the nylon fine-grain cloth, and then take out the molded outsole.

[0094] The properties of the rubber outsole semi-finished product thus obtained are shown in Table 2, and the structure is as follows figure 1 As shown, several drainage holes are formed on the side wall.

Embodiment 2

[0095] Embodiment 2, the preparation of the outsole of anti-seawater corrosion aging

[0096] The formulations are shown in Table 1.

[0097] 1) Mix, vulcanize, and granulate the rubber according to the formula ratio, and set aside;

[0098] 2) Put the material evenly in the rubber mold, and press the middle plate of the mold for 15 seconds;

[0099] 3) Open the middle plate of the mold and cover it with 0.15mm thick high-temperature-resistant nylon fine-grain cloth, close the mold and press it, exhaust once every 10s, and close the mold for 6 minutes after exhausting 3 times, the curing temperature is 160±5°C, 95MPa;

[0100] 4) Open the mold after vulcanization, gently tear off the fine nylon cloth, then take out the molded outsole, and form some drainage holes on the side wall.

[0101] The properties of the semifinished rubber outsole thus obtained are shown in Table 2.

Embodiment 3

[0102] Embodiment 3, the preparation of the outsole of anti-seawater corrosion aging

[0103] The formulations are shown in Table 1.

[0104] 1) Mix, vulcanize, and granulate the rubber according to the formula ratio, and set aside;

[0105] 2) Put the material evenly in the rubber mold, and press the middle plate of the mold for 12 seconds;

[0106] 3) Open the middle plate of the mold and cover it with 0.15mm thick high-temperature-resistant nylon fine-grain cloth, close the mold and press it, exhaust once every 10s, and then close the mold for 5.5min after exhausting for 3 times, the vulcanization temperature is 160±5°C, Pressure 90MPa;

[0107] 4) Open the mold after vulcanization, gently tear off the fine nylon cloth, then take out the molded outsole, and form some drainage holes on the side wall.

[0108] The properties of the semifinished rubber outsole thus obtained are shown in Table 2.

Abstract

The invention discloses a seawater corrosion and aging resistant rubber outsole and a preparation method thereof. The seawater corrosion and aging resistant outsole is prepared from the following rawmaterials in parts by mass: 100 phr of raw rubber; 40 to 50 phr of a reinforcing agent; 8-12 phr of a plasticizer; 3.0 to 5.0 phr of an active agent; 1.5 to 2.0 phr of a vulcanization accelerator; 1.0to 2.5 phr of an anti-aging agent; and 1.5 to 2.0 phr of a vulcanizing agent. The outsole resistant to seawater corrosion and aging has the following beneficial effects that 1, the rubber formula hasgood seawater corrosion resistance and hot sun aging resistance, and it is ensured that shoes prepared from the outsole have good durability; 2, the drainage holes are designed in the side wall of the sole, so that the probability of gravel particle blockage can be reduced, and the drainage effect is prevented from being influenced.

Description

technical field [0001] The invention relates to a rubber outsole resistant to seawater corrosion and aging and a preparation method thereof, belonging to the technical field of special rubber products. Background technique [0002] Seawater has a certain corrosion and aging effect on rubber materials. Long-term immersion in seawater and strong sunlight will accelerate the aging speed of rubber soles, thereby affecting the wearing life of shoes. For some special groups of people who often work in shallow reef beaches, the shoes are required to have better anti-stab performance, and at the same time, the shoes are required to be able to drain water quickly after landing. At present, the common shoes on the market are river-tracing shoes, and the soles have a certain drainage function, which can meet the wearing needs of ordinary people. However, for special groups who have been working in seawater for a long time (officers and soldiers guarding islands and reefs), the soles o...
