Abstract

The invention discloses a PVC (polyvinyl chloride) environment-friendly hard sheet and a preparation method thereof, and relates to the field of PVC hard sheets. Wherein the PVC environment-friendly hard sheet comprises the following components: PVC, a heat stabilizer, an internal lubricant, a processing aid, an impact modifier, a release agent, titanium dioxide and a pigment; the heat stabilizer is a calcium-zinc stabilizer or a barium-zinc stabilizer; the PVC environment-friendly hard sheet is prepared through mixing, plasticizing, extruding, high-temperature instantaneous pressing and cooling and shaping processes in sequence, does not contain organic tin or other heavy metals, is safe and environment-friendly, does not separate out oily or powdery substances in the use process, and has the characteristic of high gloss.

Description

technical field [0001] The invention relates to the field of PVC hard sheets, in particular to a PVC environment-friendly hard sheet and a preparation method thereof. Background technique [0002] The PVC hard sheet used in the fields of toys, home decoration, packaging, decorations, etc. in the domestic market, because of its small thickness, only 0.2-0.6mm, so it heats up quickly during processing, but the heat resistance of PVC is poor. During the process, PVC often decomposes after being heated, resulting in a large number of black spots or impurity spots in the product. [0003] In order to reduce the difficulty of production and processing, most current manufacturers use additives containing heavy metals such as organotin stabilizers to improve the heat resistance of PVC, or use a large amount of external slipping agent or plasticizer in the formula to reduce the glass resistance of PVC. However, the hard PVC sheet prepared by the above method will precipitate oily or...
