Embodiment 1
[0031] The manufacturing method of steering wheel cover comprises the following steps:
[0032] (1) After heating the resin to 35°C, add a curing agent, mix well, spray it into the model of the massage part, obtain the massage part after casting, and perform demoulding treatment on the massage part;
[0033] (2) Heat the high molecular polymer to a temperature of 200°C, spray it into the anti-slip layer mold after melting, and fill the anti-slip layer mold;
[0034] (3) Pressure-hold the anti-slip layer mold as a whole in step (2) for 30 minutes to increase the density of the polymer in the anti-slip layer mould;
[0035] (4) The anti-slip layer mold in step (3) is cooled for the first time, and the temperature for the first time is 80°C;
[0036] (5) Demoulding the anti-slip layer mold that has undergone the first cooling treatment in step (4), to obtain an anti-slip layer with anti-slip lines on the inner surface;
[0037] (6) Take the elastic mesh and the massage part in ...
Embodiment 2
[0043]The manufacture method of steering wheel cover is the same as embodiment 1, and difference is:
[0055] The second cooling temperature in step (7) is 80°C.

Abstract
The invention relates to a manufacturing method of a steering-wheel sleeve. The manufacturing method comprises the following steps: adding resins into a solidifying agent so as to obtain a mixture, jetting the mixture into a massage-part mold, and casting the massage-part mold so as to obtain massage parts; heating and fusing high-molecular polymers, jetting the fused high-molecular polymers into an antislip-layer mold, and filling the antislip-layer mold; performing pressure maintaining on the whole antislip-layer mold; performing primary cooling on the pressure-maintained antislip-layer mold; performing mold release treatment on the cooled antislip-layer mold so as to obtain an antislip layer; taking elastic mesh cloth, and compressing and bonding the elastic mesh cloth and the massage parts by high-temperature hot treatment so as to obtain a first external ring sleeve body; performing secondary cooling on the first external ring sleeve body so as to obtain a second external ring sleeve body; and cutting the second external ring sleeve body till the surface of the second external ring sleeve body is larger than the outer surface of the antislip layer so as to obtain a third external ring sleeve body. The scheme adopted by the method disclosed by the invention is simple in manufacturing operation, and products are easy to obtain; manufactured products are high in safety coefficients, beautiful, and suitable for a wide range of popularization and use.
Description
technical field [0001] The invention relates to the field of manufacturing a steering wheel cover, in particular to a manufacturing method of a steering wheel cover. Background technique [0002] Steering wheel covers currently on the market are mostly rubber or leather products. For example, a steering wheel cover disclosed by the announcement number CN203727453U (2014-07-23) includes a steering wheel cover body that can completely cover the steering wheel. The inner side of the cover body is provided with a cladding layer, and the cladding layer is filled with automobile deodorant, and the outer material of the steering wheel cover body is leather. Rubber and leather products are not only not resistant to high temperature, but also not environmentally friendly. Although the appearance is beautiful, the leather production method is cumbersome, and most of the steering wheel covers obtained from rubber are disposable and do not have the function of recycling.
