Abstract

The invention relates to a PVC film for lamp box cloth and a preparation method of the PVC film and relates to the technical field of lamp box cloth. The PVC film comprises the following raw materials, by mass, 55-65 parts of PVC resin, 10-15 parts of a methyl methacrylate-butadiene-styrene terpolymer , 5-10 parts of chlorinated polyethylene, 15-20 parts of plasticizer, 2.5-3.5 parts of a stabilizer, 70-75 parts of heavy calcium carbonate, 1-3 parts of bentonite, 3.8-4.5 parts of anatase titanium dioxide, 0.01-0.05 part of a fluorescent whitening agent, 0.2-0.6 part of an ultraviolet light absorber, 0.1-0.5 part of a flame retardant, 0.1-0.3 part of a lubricant and 0.005-0.01 part of a pigment. By improving the thermal stability of the PVC film, the use stability of the lamp box cloth is improved, and the use time of the lamp box cloth is prolonged.

Description

technical field [0001] The invention relates to the technical field of light box cloth, in particular to a PVC film for light box cloth and a preparation method thereof. Background technique [0002] Light box cloth is mainly used as outdoor material or for the production of large-scale advertisements because of its good flexibility, uniform light transmission, long life, easy installation, and good ink adhesion. A layer of light box film is generally placed on the surface or bottom of the light box cloth. , used to improve the overall use effect of the light box cloth. PVC film is commonly used for light box film. The main component of PVC film is polyvinyl chloride, which is yellowish translucent, shiny and has good rainproof and antistatic properties. Therefore, it is more and more used in light box film. more extensive. [0003] The Chinese Patent Publication No. CN108641248A discloses a stretch-resistant PVC film for light box cloth and a preparation method thereof, c...
