Example Embodiment
[0062] Example 1
[0063] In parts by weight, 100 parts of natural rubber latex, 5 parts of vulcanization package dispersion, 3 parts of potassium oleate aqueous solution, 1 part of potassium ricinoleate aqueous solution, 0.1 parts of potassium pyrophosphate, 0.2 parts of stabilizer laurel Potassium acid, 0.2 parts of stabilizer soy soft phospholipid. The mixed latex was aged in a water bath at 30°C for 10 hours. The temperature of the mixed latex was controlled at 26°C during production. The temperature of the curing agent is controlled to 22°C, the solid content is 20%, and the pH value is 5. The mold temperature is controlled at 40°C.
