DETAILED DESCRIPTION
[0059] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application.

[0062] S1. Raw material processing, the raw material includes MBC, PVC material and catalyst, a certain proportion of MBC, PVC material and catalyst is mixed to form the raw material;
[0063] S2. The PVC material is in powder form and is added to the MBC along with the catalyst in a fluid state to form a raw material;
[0064] S3. The raw material is processed in an extrusion device and the MBC is mixed with the PVC material and the catalyst after entering the extrusion device.
[0065] As can be seen from the embodiment, the MBC (MBC is the abbreviation of Mineral Based Composite, which is the full name of Mineral Based Composite) is mixed with the PVC material and the catalyst, and the MBC is mixed with the PVC material and the catalyst before being melted at high temperature to a fluid state, and then the PVC material is directly mixed into the MBC in a fluid state, so that the PVC material is directly wrapped by the MBC, and is melted at the temperature of the MBC (the melting point of PVC is 212℃), so that the harm of the gas generated by the carbonization of the PVC material at high temperature to the human body can be effectively eliminated. It is known that the gas generated by the object during the carbonization process is the manifestation of the diffusion of the particulate matter of the object itself into the air, so that the PVC material in the MBC fluid will be wrapped by the MBC even when the carbonization phenomenon occurs, so as to reduce the harm during production and protect the workers.
[0066] During the mixing process, the MBC (in a fluid state) directly wraps the PVC material inside, which can effectively reduce the dispersion of harmful substances generated by the PVC material at high temperature in the air, thereby protecting the workers.
