Embodiment 1

[0060] Example 1 A kind of natural rubber sole surface defect rapid repair glue and preparation method thereof

[0061] The preparation method of the above-mentioned natural rubber sole surface defect fast repair glue, it carries out according to the following steps:

[0062] (1) Mastication of natural rubber

[0063] Put the natural rubber into the 450-type open mill for mastication, adjust the distance between the rollers of the open mill to 1.5mm-2mm, pass the natural rubber six to seven times, and test the plasticity of the natural rubber. The plasticity is required to be 0.55-0.60, if it does not meet the requirements, continue to thin it until it is qualified. In this way, natural rubber that meets the requirements of mastication is obtained;

[0064] (2) Preparation of raw materials

[0065] Accurately weigh the masticated natural rubber and other required raw materials according to the table below, and set aside;

[0066] material name Weight (kg) ...

Embodiment 2-7

[0079] The difference between embodiment 2-7 and embodiment 1 is only the difference in the consumption of the raw material composition involved, and its preparation method is the same, and the specific difference is as shown in the following table:

Abstract

The invention discloses quick repairing glue for surface defects of natural rubber soles and a preparation method of the quick repairing glue. Compared with the prior art, the quick repairing glue has the advantages that magnesium oxide is added to components of an active agent, so that the agent is suitable for vulcanization at a low temperature, the vulcanization speed can be raised, and the specific operation is convenient. The quick repairing glue can be adhered to the soles well; the soles repaired by the quick repairing glue can be highly chemically combined with the repairing glue and cannot fall off; and therefore, shoes and boots with defects can be effectively repaired by the quick repairing glue. The quick repairing glue is suitable for quick repair within small ranges of the defects, such as hungry joint and bubbles on the surfaces of the rubber soles, caused by formation pressure, rubber, dies and the like in production process of shoes and boots.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a natural rubber sole surface defect quick-repair glue and a preparation method thereof. Background technique [0002] In the production process of natural rubber soles, due to the influence of various factors such as vulcanization pressure, the fluidity of the rubber material, and the shape of the mold, some defects such as air bubbles and lack of rubber will exist on the surface of the sole after vulcanization and molding. Although these surface defects It will not affect the quality of wearing, but it will affect the appearance. So this needs to be modified. After retouching these finished shoes can be downgraded for factory sale. The current repair method is to spot wax on the defective part of the sole. Yet these paraffin waxes can cause it to come off from the sole because it does not form an effective combination with the rubber sole during the actual wearing process of ...
