Artificial leather is widely used in the fields of shoes, clothing, home decoration, etc. In its production, calendering and coating are the two key processes.
1.Calendering
Firstly, prepare materials by uniformly mixing PVC resin powder, plasticizers, stabilizers, fillers, and other additives according to the formula. Next, the mixed materials are fed into the internal mixer, where they are plasticized into uniform and flowable lumps under high temperature and strong shear force. Subsequently, the material is sent to the open mill, and as the rollers continue to rotate, the material is repeatedly squeezed and stretched, forming continuous thin sheets. This sheet is then fed into a multi roll rolling mill, where the temperature, speed, and spacing of the rollers need to be precisely controlled. The material is rolled layer by layer between the rollers to produce a semi-finished product with uniform thickness and smooth surface. Finally, after a series of processes such as lamination, printing, embossing, and cooling, the production is completed.
TopJoy Chemical has Ca Zn stabilizer TP-130,which is suitable for PVC calendered products. With its excellent thermal stability performance, it effectively prevents quality problems caused by thermal decomposition of polyvinyl chloride under specific pressure and temperature control, ensuring smooth stretching and thinning of raw materials, and forming uniformly thick artificial leather sheets. Used for car interiors and furniture surfaces, durable and comfortable.
2.Coating
Firstly, it is necessary to prepare a coating slurry by mixing PVC paste resin, plasticizers, stabilizers, pigments, etc., and using a scraper or roller coating equipment to evenly coat the slurry on it. The scraper can accurately control the thickness and flatness of the coating. The coated base fabric is sent into an oven, and under suitable temperature conditions, the PVC paste resin undergoes plasticization. The coating is tightly bonded to the base fabric, forming a tough skin. After cooling and surface treatment, the finished product has rich colors and diverse textures, which are commonly used in fashion fields such as clothing and luggage.
TopJoy Chemical has Ba Zn stabilizer CH-601,which has excellent thermal stability and good prossess excellent dispersion,can effectively prevent PVC from degradation and performance degradation caused by heat and light factors during processing and use.It has good compatibility with resin, is easy to disperse evenly in the resin, and does not cause roller sticking, which helps to improve production efficiency and product quality.
TopJoy Chemical has developed different heat stabilizers based on customers’ requirements for synthetic leather products, such as transparency and foaming, to assist in the production of high-quality synthetic leather products.Welcome to contact with us for deep cooperation.
