Description

Technical Field

[0001] The invention relates to the technical field of floor films, in particular to a temperature-resistant deformable floor film and a preparation method thereof. Background Art

[0002] Floor membranes are rectangular rolls made from polyethylene granules through a series of secondary processes, including high-temperature melting, high-temperature lamination, and forming and cutting. They typically consist of polyethylene foam covered with a layer of PE or aluminum film. The polyethylene foam provides shock absorption, sound insulation, and floor leveling, while the PE film provides moisture resistance. Floor membranes are available in a variety of materials and types, including PVC, EVA, and woven fabric, to meet diverse renovation needs.

[0003] After searching, a milling device for a motor end cover with the publication number CN108580984A was disclosed, which includes: a milling machine, which includes a milling head; a positioning unit, which is arranged on the milling machine; a conveyor belt, on which the motor end cover to be processed is transported; a manipulator; wherein, the milling head includes a milling head; the positioning unit includes a cylinder with a base provided on the top of a piston rod, a pair of grippers that are overlapped and hingedly provided on the base, a bearing plate, a sleeve, a limit column, and multiple support columns. A center hole is formed in the center of the motor end cover, and a through hole is formed in the center of the bearing plate. The cylinder drives a pair of grippers to perform linear reciprocating motion in the vertical direction, so that the grippers are folded or expanded under the action of the limit column. The present invention automatically transports the motor end cover to be processed to the positioning unit through a conveyor belt and a manipulator, which effectively reduces the labor intensity of workers and improves production efficiency.

[0004] During the use of an existing temperature-resistant deformable floor film, the motor end cover is observed and monitored by a camera, and the condition of the motor end cover detected by the camera is adjusted and processed. However, during the processing of the motor end cover, the motor end cover will produce some debris and even some sparks. These debris or sparks can easily adhere to the surface of the camera, affecting the use of the camera and the processing effect. Moreover, when the motor end cover processing is monitored by the camera, it is easily affected by the surrounding light. Some motor end covers are in a relatively dark environment, which affects the camera's monitoring and makes it impossible to distinguish the processing situation. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a temperature-resistant deformable floor membrane and a preparation method thereof, which solves the problem that during use of the existing temperature-resistant deformable floor membrane, the motor end cover is observed and monitored by a camera, and the condition of the motor end cover detected by the camera is adjusted and processed. However, during the processing of the motor end cover, the motor end cover will produce some debris and even some sparks. These debris or sparks can easily adhere to the surface of the camera, affecting the use of the camera and the processing effect. Moreover, when the motor end cover processing is monitored by the camera, it is easily affected by the surrounding light. Some motor end covers are in a relatively dark environment, which affects the camera's monitoring and makes it impossible to distinguish the processing condition.

[0017] Preferably, the modified carbon fibers and silicon carbide fibers are carbon nanotube fibers covered with a titanium dioxide coating.

[0018] By adopting the above technical solution, the modified carbon fibers and silicon carbide fibers, which can be chopped or continuous, form a three-dimensional network structure within the coating matrix, thereby improving the material's crack resistance and impact resistance. This can increase the coating's fracture toughness and prevent breakage and flaking caused by impact.

[0019] Preferably, the auxiliary plasticizer is one of tributyl citrate, di-n-octyl phthalate, butyl benzyl phthalate, and diisononyl phthalate.

[0020] By adopting the above technical solution and adding auxiliary plasticizers, internal and external double plasticization is effectively produced, thereby generating a synergistic plasticizer, effectively improving the tensile properties of the PVC flame retardant floor film.
