[0060] Example 1 Natural rubber sole surface defect quick repair glue and preparation method thereof
[0061] The preparation method of the above-mentioned natural rubber sole surface defect quick repair glue is carried out in the following sequence of steps:
[0062] (1) Plasticizing of natural rubber
[0063] Put the natural rubber into the 450 open mill for plasticization, adjust the roller distance of the open mill to 1.5mm-2mm, pass the natural rubber thinly through six to seven times, and perform the plasticity test of the natural rubber. The required plasticity is 0.55-0.60, if it does not meet the requirements, continue to pass until it is qualified. In this way, a natural rubber that meets the mastication requirements is obtained;
[0064] (2) Preparation of raw materials
[0065] Accurately weigh the plasticized natural rubber and other required raw materials according to the following table, and set aside;
[0066] Material name Weight (kg) natural rubber100 Zinc oxid...
