Abstract
The invention relates to a method for preparing a rigid transparent propenepolymer (PP) industrial sheet material. The raw materials in the method comprise, by weight percentage, 55-65 wt% of PP particles, 18-23 wt% of PPR particles and 18-23 wt% of organosilicone, wherein a full automation computer is utilized to measure and control the components, and the sum of the mass percentage of the raw materials is 100 wt%. The method comprises a step (1) of mixing the PP particles and the PPR particles to form a first grade alloying; a step (2) of adding the organosilicone, performing second grade blending, and obtaining a raw material composition after uniform mixing; a step (3) of raising the temperature of the raw material composition to 130 DEG C and performing automation low temperature blending and optimized control; and a step (4) of cooling and automatically conveying the materials, performing preparation extrusion and plastification through double screws, performing extrusion molding through a neck mould and stabilizing formalization of sizes and a cooling device to obtain the rigid transparent PP industrial sheet material. The rigid transparent PP industrial sheet material prepared by the method has high rigidity and reaches 100 Shorehardness or above, the good transparency reaches 70-80%, and the rigid transparent PP industrial sheet material is widely utilized in liquid level observation positions in a chemical device and a pipeline and is involved in industrialization production.
Description
technical field [0001] The invention belongs to the field of industrial sheet preparation, and in particular relates to a method for preparing a rigid transparent PP industrial sheet. Background technique [0002] In chemical equipment and many pipelines, etc., it is necessary to be able to see the liquid surface or the state of the fluid on the other side, and to improve the permeability of the product. [0003] In order to obtain a balance of rigidity and toughness for ordinary PP sheets, it is necessary to use copolymerized PP, so that the color of the sheet becomes opaque. In many industrial products, PPR materials with high transparency are used to produce plates, but the rigidity cannot be satisfied. Especially the surface hardness drops sharply. [0004] This field needs to develop a kind of industrial plate, its hardness and transparency are moderate, can be used in chemical equipment and many pipelines, it is convenient to observe the liquid surface or fluid on th...
