preparation example Construction

[0026] The embodiment of the present invention provides a preparation method of a PVC substrate, which uses the above-mentioned components in the PVC substrate as raw materials for preparation, mainly by controlling the dosage of each component and the addition of stabilizers and plasticizers to overcome the brittleness of the substrate. Problems, so that the performance of the substrate is relatively excellent.

[0027] Specifically, in the preparation process, the raw materials are pulverized to a specified particle size, sieved, dried, mixed evenly in proportion, and then extruded.

[0028] In some embodiments, the mixing temperature of raw materials is 100-130°C, and the temperature of extrusion molding is 160-200°C. In terms of mass fraction, it is dried until the water content is 8-10%. By further controlling the process parameters, the raw materials can be mixed evenly under high-speed stirring, and the PVC floor with excellent performance can be prepared.

Abstract

The invention discloses a PVC substrate, a preparation method thereof and a PVC composite floor, and relates to the technical field of PVC floors. The inventor uses PVC resin, construction waste powder (without reinforcing steel bars), straw powder and lime powder as raw materials, a stabilizer and a plasticizer are added to prepare a PVC base plate, and the PVC base plate is prepared from, by weight, 550-630 parts of PVC resin, 700-780 parts of construction waste powder, 150-200 parts of straw powder, 500-600 parts of lime powder and 10-30 parts of an additive; the additives comprise a plasticizer and a stabilizer; wherein the construction waste powder is selected from at least one of waste cement powder and waste stone powder, and the straw powder is selected from at least one of wheat straw and corn straw. By adding the plasticizer and the stabilizer and regulating and controlling the dosage of each component, the PVC substrate with various properties meeting the requirements can be finally prepared, the preparation cost of the floor is remarkably reduced, and waste is turned into wealth.

Description

technical field [0001] The invention relates to the technical field of PVC flooring, in particular to a PVC substrate, a preparation method thereof and a PVC composite flooring. Background technique [0002] At present, the output of straw is very large. During summer harvest and autumn and winter, there is always a large amount of wheat, corn and other straws burned in the field, which produces a lot of thick smoke, which is not conducive to environmental protection in rural areas. Increase the research and development of comprehensive utilization technology of agricultural waste such as straw, and use straw resources scientifically and efficiently. On the one hand, it can turn waste into treasure, improve resource utilization, and increase farmers' income; healthy. [0003] In addition, with the rapid development of the construction industry, the accompanying construction waste is increasing. The amount of construction waste has accounted for more than 1 / 3 of the total ur...
