Abstract

The invention discloses a technology for processing floor films, and relates to the field of floor film processing. The technology for processing the floor films includes steps of (1),mixing ingredients, to be more specific, weighing, by weight, PVC (polyvinyl chloride) resin powder, impact-resistant MBS (methyl methacrylate) resin, ACR (acrylamide) processing agents, di-iso-decylphthalate, internal lubricants, 3-10 parts of external lubricants and phosphate ester flame retardants, stirring the ingredients at the high speeds, and then carrying out cold stirring on the ingredients to obtain mixed materials; (2), carrying out extrusion, plasticization and calendaring molding on the mixed materials; (3), carrying out cooling and ageing treatment; (4), carrying out traction, winding and packaging. The technology has the advantages that the floor films are reasonable in composition proportion, high in light transmittance and suitable for large-scale industrial production, the technology isreasonable in design, and the toughness, the abrasion resistance, the flame retardance and the temperature resistance of the floor films can be enhanced.

Description

Technical field: [0001] The invention relates to the technical field of floor film processing, in particular to a processing technology of floor film. Background technique: [0002] Floor film is very important in the decoration industry. Because it has super shockproof, anti-collision, anti-friction, and corrosion-resistant characteristics, it can provide all-round protection for the decoration ground and floor, and effectively prevents sharp objects from falling during the decoration process. The ground is damaged, and the wear caused by the friction of the sole against the ground can also be avoided. When the traditional floor film processing process is used, the wheel sticking phenomenon is easy to occur; during the stretching process of the product, it is easy to cause serious whitening and affect the apparent transparency, and it is easy to appear difficult to coil. Therefore, it is necessary to develop a processing technology that can ensure the toughness, wear resis...
