Abstract

The invention relates to the technical field of shoelaces, and particularly relates to a manufacturing method of a soft rubber shoelace head. The manufacturing method comprises the following steps: 1, filling a cavity of a three-dimensional mould with a suspension position with a rubber material; 2, enabling one end of a shoelace to sequentially pass through the cavity of the three-dimensional mould, and tensioning two ends of the shoelace by using the suspension position; and 3, closing the three-dimensional mould and then carrying out vulcanization-shaping in a vulcanizing machine, wherein the rubber material comprises the following components in parts by weight: 90-120 parts of synthetic rubber, 40-55 parts of white smoke, 8-15 parts of softening oil, 1-4 parts of an accelerant and 3-6 parts of a processing agent. The shoelace head manufactured by using the manufacturing method has the relatively good physical property and flexibility without being easily broken, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of shoelaces, in particular to a method for making a soft rubber shoelace head. Background technique [0002] The current shoelaces are all wrapped with a layer of hard glue. During use, when the shoelaces are dragged to the ground, they are easy to be stepped on and sometimes crushed; sometimes the hard shoelaces fall into the shoes. Also because it is too hard, the instep of the human body will be pushed to the instep and even the skin on the instep will be injured; it is not very convenient to use, so it is necessary to reduce the hardness of the rubber wrapping the shoelace head, and the current process is difficult to wrap a layer of soft rubber on the shoelace head. glue. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art, and provide a method for making soft rubber shoelace heads, which can produce shoelace heads with certain flexib...
