Problems solved by technology

Therefore, a large number of researchers began to engage in the comprehensive utilization research of phosphogypsum, and used phosphogypsum as a raw material for building materials, such as thermal insulation blocks, etc.; some researchers used it as a raw material for the preparation of calcium oxide and sulfur dioxide etc.; but despite this, the annual comprehensive utilization rate of phosphogypsum is less than 10%, making the comprehensive utilization and development of phosphogypsum still need to further increase the process

Abstract

The invention provides a method for preparing a PVC profile with the anti-aging effect and belongs to the technical field of PVC profile production. The method is prepared from, by weight, 90-110 parts of polyvinyl chloride resin, 50-60 parts of ardealite, 3-8 parts of titanium dioxide, 1-3 parts of polyvinyl alcohol, 1-2 parts of polylactic acid, 1-4 parts of stabilizer, 0.5-2 parts of antioxidant, 1-2 parts of lubricant and 1-2 parts of composite plasticizer. The method includes the steps of ardealite treating, mixing, extrusion forming and finished product forming. Polyvinyl alcohol is used for modifying ardealite, so that ardealite is used for replacing calcium powder used in the preparation process of a traditional PVC profile, the source of calcium powder for PVC is expanded, the cost of the calcium powder for PVC production is reduced, comprehensive utilization ways of ardealite are expanded, the comprehensive utilization rate of ardealite is increased, in cooperation with titanium dioxide, polylactic acid, stabilizer, antioxidant, lubricant and composite plasticizer, the notch impact strength, tensile strength, bending strength, bending modulus and elongation at break are increased to be better, the service life is longer, and the better anti-aging characteristic is achieved.

Description

technical field [0001] The invention belongs to the production technical field of PVC profiles, and in particular relates to a method for anti-aging PVC profiles. Background technique [0002] Phosphogypsum is the solid waste of the phosphate fertilizer industry, and phosphoric acid is the foundation of the phosphate fertilizer industry. The wet process phosphoric acid production process is the most commonly used phosphoric acid production process. In the wet-process phosphoric acid production process, sulfuric acid is first used to decompose phosphate rock powder to produce extraction slurry, and then filter and wash to obtain phosphoric acid, and phosphogypsum waste will be generated during the process of filter and wash. Generally, about 5-6 tons of phosphogypsum are produced for every ton of phosphoric acid produced, and 2.5-5 tons of phosphogypsum are discharged for every ton of diammonium phosphate produced. With the rapid development of my country's high-concentrati...
