Description

Method for manufacturing composite fabric

The present invention relates to a method of manufacturing a composite fabric, and more particularly to a method of manufacturing a composite fabric capable of using a continuous and discontinuous vulcanization procedure.

Nowadays, the demand for rubber thin products is increasing. The related thin products such as fire resistant protective clothing, medical bed cover and bag leather have been widely used in industrial and consumer goods.

The rubber compound usually needs to be added with high strength and high elasticity through the vulcanization process of the vulcanization section. High wear resistance, corrosion resistance and other excellent properties.

In general, the previous vulcanization process uses continuous production. Although the product can be completed at one time without segmentation, the line speed limit of the over-optical section and the abnormality of the vulcanization section machine often cause other sections to stop. In addition to causing excessive processing time, it may also affect the quality and stability of the rubber compound after sulfur addition.

In view of this, the inventors have made many researches and improvements on how to improve the vulcanization quality and efficiency of rubber rubber materials based on years of experience in the manufacture, development and design of rubber products, and finally obtained a practical invention.

After mixing for 5 minutes in the temperature range, the vulcanization additive was added and kneaded for two minutes at two rolls in a temperature range of 70 to 80 degrees Celsius. Further, the compound 13 formed by the kneading is attached to the adhesive layer 12 by a continuous rubber calender (Calender) 21 at a temperature ranging from 90 to 100 degrees Celsius, and the thickness of the rubber 13 is approximately 0.25. Between 0.3 cm.

Finally, step 16 is performed when the composite material is transferred to the vulcanization section of the production line, and the composite material is subjected to a Vulcanization procedure in an upright hot air oven (Oven) 22. It is worth mentioning that, in this embodiment, the vulcanization procedure may be a continuous vulcanization procedure or a discontinuous vulcanization procedure, wherein the continuous vulcanization procedure refers to a composite self-continuous rubber calender 22 After the output, the vertical hot air oven 22 is directly introduced into the vulcanization process; in addition, the discontinuous vulcanization process means that the composite material is produced from the continuous rubber calender 22, and then taken up and sent through the take-up seat 23. The other vertical hot air oven 22 is subjected to a vulcanization procedure.

In more detail, in the continuous vulcanization process and the discontinuous vulcanization process, the composite material is passed through the vertical hot air oven 22 to be 300 The vulcanization distance to 400 yards and the production rate of 15 to 25 meters per minute are vulcanized, so that the rubber 13 is crosslinked by the intermolecular molecules of the rubber to form a vulcanizate having a network structure of three, thereby having high strength. High elasticity, high wear resistance and corrosion resistance, and can eliminate permanent deformation, so that the rubber can be quickly and completely restored after deformation.

In summary, the method for manufacturing the composite fabric of the present invention can select a continuous vulcanization procedure or a discontinuous vulcanization procedure according to the condition of the production line, and even if the continuous vulcanization equipment on the production line is abnormal, the non-continuous vulcanization process can be used.
