Problems solved by technology

[0002] At present, there are many sandwiches on the market that are produced by coating and scraping. The sandwich cloth produced by this process has some technical defects, that is, the product’s lamination fastness is poor, and the material is peeled off and cracked due to long-term fatigue use. Although the two-layer process is firmly bonded, the surface of the coating is sticky due to the migration and precipitation of the internal plasticizer, making the product easy to stick to dust, cracking, and premature failure of the product, especially for conveyor belts for treadmills or industrial belts, etc. Materials, more wear-resistant materials are needed

Embodiment 1

[0041] The specific steps of the process are:

[0042] 1) Sending: the gray cloth is placed on the sending device for sending, and one end of the core tube on the sending device is equipped with a magnetic brake device for adjusting the tension;

[0043]2) Preheating and ironing: the gray cloth is preheated and ironed through the preheating and ironing device on the sending device; this step is a set of heating steel rollers, and the temperature is controlled at 80 degrees;

[0044] 3) Paste on the padding vertical scraper: dip the preheated gray cloth into the paste so that the warp and weft of the cloth are filled with paste, and then pass through a pair of rolls to roll off the excess paste, vertically Scrape the excess paste with a scraper, adjust the paste amount of each cloth by adjusting the viscosity of the paste, the pressure of the roll and the gap between the scrapers to 300g / m 2 ;

[0045] 4) Pre-plasticized gel treatment: drying the padded and pasted gray cloth ...

Abstract

The invention provides a process for a conveyor belt for a running machine, which comprises the steps of grey cloth delivery by grey cloth delivering device, preheating and ironing, pasting by a padding vertical scraper, pre-plasticization by a vertical drying oven, planishing and cooling, primary horizontal head coating, pre-plasticization and gelation, cooling and sizing, secondary head coating, drying oven plasticization, embossing, cooling, coiling and surface coating. The process adopts sandwich mesh fabric coating and a surface treatment process, is complete in process compared with common coating processing and can process vertical coatings, surface and bottom. The products processed by the process are good in air tight performance, suitable for outdoor use, long in service life, good in wear resistance and high in surface quality and have obvious economic value.
