Problems solved by technology

At present, people mainly add toner to the material to achieve the color requirements of the material, but because the toner is dispersed very unevenly in the reinforcement system, the color of the material is inconsistent; in addition, due to the addition of toner, it is easy to cause glass fiber and The interface separation between polyvinyl chloride resins makes the mechanical properties of the material drop significantly

Abstract

The invention provides a polyvinyl chloride material and a preparation method thereof, which is prepared from the following components in parts by weight: 50-100 parts of polyvinyl chloride, 5-35 parts of glass fiber, and 3-10 parts of synergistic coloring enhancer 0.5-5 parts of masterbatch, 0.1-0.5 parts of antioxidant, 0.1-1.0 parts of lubricant, prepared by mixing and extruding. The invention introduces ultra-low viscosity polyvinyl chloride, which ensures the overall fluidity and processability of the material; while the synergistic coloring enhancer keeps the material stable in mechanical properties, the overall material has very good coloring ability and good toner dispersion. Therefore, the prepared product of the present invention is bright in color, uniform in distribution, maintains good performance, and has good color uniformity.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyvinyl chloride material and a preparation method thereof. Background technique [0002] Polyvinyl chloride plastic (PVC for short) is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Pure polyvinyl chloride resin is a hard thermoplastic material, and its decomposition temperature is very close to the plasticization temperature. With the continuous development of its applications, people have put forward higher and more specific requirements for PVC. For example, people have more pursuits for the color of products, which requires processing materials to have various bright appearances. At present, people mainly add toner to the material to achieve the color requirements of the material, but the color of the material is inconsistent due to the very uneven dispersion of the toner in the reinforcement system; in addi...
