Plastic surface wallpaper production process 1, the composition of the plastic surface wallpaper. Simply put, polyvinyl chloride (commonly known as PVC) is evenly coated on the surface of the base paper to form a plastic surface wallpaper. In actual production, it is not possible to simply have PVC on the surface of the base paper, but there are other chemical materials that have been stirred and dissolved together. These mixtures are usually called: pastes. The main components of the paste consist of: PVC, DOP, calcium carbonate plus proper amount of stabilizer, titanium dioxide, and viscosity reducer in a certain proportion. In addition, according to different needs, it is necessary to add foaming agents, flame retardants, whitening agents, antioxidants and other accessories. PVC (polyvinyl chloride), Chinese name: PVC. It is the main constituent material of raw materials. DOP (dioctyl phthalate, Chinese name is: dioctyl acid ester, is a synthetic resin plasticizer, as a plasticizer, can make the wallpaper softer. Calcium carbonate (Caco3) plays a filling role, can improve the mechanical strength of the wallpaper. PVC, DOP Calcium carbonate is transparent after it has been gelatinized (chemical reaction, as described below), so it is necessary to add titanium dioxide to create a white background and play a hiding role.The stabilizer can make the gelation process proceed slowly. The agent is used to adjust the paste viscosity.
