Description

Technical Field

[0001] The invention relates to the technical field of commercial floor production, in particular to an environmentally friendly commercial floor and a preparation method thereof. Background Art

[0002] Traditional ceramic floors, solid wood floors, and composite floors have the problems of being hard to the feet, easy to deform, and exceeding the formaldehyde standard. PVC floors came into being to meet people's needs. The main component of PVC floors is polyvinyl chloride materials. At present, the main components of PVC floors are PVC powder, stone powder, and additives that are extruded. This type of floor is not easy to decompose, and PVC itself contains halogens, which can easily decompose into toxic gases in the event of a fire, which is very toxic to humans. PVC floors contain a lot of PVC powder, and there are drawbacks such as long-term environmental pollution caused by waste gas boards and difficult to decompose. Therefore, in the process of tobacco planting, biochar slow-release tobacco planting fertilizer and its preparation method are needed.

[0003] The inventor found that there are at least the following problems in the prior art that have not been solved: 1. The existing floor is not easy to decompose, and PVC itself contains halogens, which are easy to decompose toxic gases in the event of a fire, which is very toxic to humans. The PVC floor contains a large amount of PVC powder, and there are long-term environmental pollution caused by waste gas boards, and it is not easy to decompose; 2. When manufacturing the floor, because the temperature in the extruder barrel is constant, the material extrusion quality is poor when the material is extruded, and it is inconvenient to shape the material, thereby reducing the quality and production efficiency of the floor production; 3. After the bottom plate is produced, the chemical properties inside the bottom plate are not tested, and it is impossible to determine whether the chemical properties of the floor meet the standards, thereby reducing the success rate of floor production. For this reason, the present invention designs a commercial floor with environmental protection function and a preparation method thereof. Summary of the invention

[0004] The purpose of the present invention is to provide a commercial floor with environmental protection function and a preparation method thereof, so as to solve the problems that the existing floor mentioned in the above background technology is not easy to decompose, and PVC itself contains halogen, which is easy to decompose toxic gases in the event of a fire, which is very toxic to humans. The PVC floor contains a large amount of PVC powder, and there is a long-term environmental pollution caused by waste gas plates, and it is not easy to decompose. In addition, when manufacturing the floor, because the temperature in the extruder barrel is constant, the material extrusion quality is poor, and it is inconvenient to shape the material, thereby reducing the quality and production efficiency of the floor production. Moreover, after the bottom plate is produced, the chemical properties inside the bottom plate are not tested, and it is impossible to judge whether the chemical properties of the floor meet the standards, thereby reducing the success rate of the floor production. To this end, the present invention designs a commercial floor with environmental protection function and a preparation method thereof.
