Problems solved by technology

The disadvantage of rigid transparent PVC film is poor flexibility and elasticity, which limits its use in some specific occasions
[0005] The Chinese patent with the publication number CN 103467888A and the patent name "Soft PVC functional film with solar spectrum selective transmission and its preparation method" discloses a soft transparent PVC functional film although the The inhibition rate is as high as 99.8%, and the transparent soft PVC functional film can only effectively shield the single function of ultraviolet light
The Chinese patent with the publication number CN 104693646A and the patent name "A Transparent Plasticized PVC Functional Film and Its Preparation Method" discloses a transparent plasticized PVC functional film that can effectively shield ultraviolet rays and effectively shield high-energy visible light-blue light and infrared rays. Among them, the average transmittance of 400-500nm high-energy visible light (blue light) is 24.3-76.2%, and the inhibition rate of blue light is not high; when the average transmittance of 400-500nm blue light reaches 24.3%, the average transmittance of visible light is only 35.3%. The practical application of occasions with high requirements for shielding blue light is limited. For example, in some occasions, the average transmittance of blue light is required to be below 1%.
The above two kinds of plasticized PVC functional films are not flame retardant, which further limits their application in related fields such as electronics and electrical appliances.
[0006] In summary, the transparent plasticized PVC functional films currently in use only have the functions and functions of effectively shielding ultraviolet rays and effective high-energy visible light (blue light), especially for high-energy visible light (blue light). Transparent plasticized PVC functional films are not flame retardant

The invention discloses an inflaming-retarding transparent plasticized PVC (Polyvinyl Chloride) functional thin film and a preparation method. The inflaming-retarding transparent plasticized PVC functional thin film has the characteristics of selectively transmitting and absorbing a solar spectrum and multiple functions of efficiently shielding ultraviolet rays, infrared rays, energetic visible light-blue light and the like. The inflaming-retarding transparent plasticized PVC functional thin film has an average shielding rate, which is up to 99 percent or above, in a 200nm to 400nm of ultraviolet waveband and an average inhibition rate, which is up to 99 percent or above, for 400nm to 500nm of the energetic visible light (blue light), and meanwhile, has a limit oxygen index which is more than 30 percent. The inflaming-retarding transparent plasticized PVC functional thin film provided by the invention is prepared from the following raw materials by mass: 100 parts of PVC resin, 60 to 70 parts of compound plasticizer, 2 parts of compound heat stabilizer, 0.1 to 1 part of compound light stabilizer, 0.1 to 0.5 part of functional pigment and 0.5 to 1 part of surface graft-modified metallic oxide.

Description

technical field [0001] The invention relates to a PVC film and a preparation method thereof, in particular to a flame-retardant transparent plasticized PVC functional film and a preparation method thereof. Background technique [0002] Polyvinyl chloride resin (PVC) is a typical amorphous polymer with excellent transparency and is especially suitable for making transparent films. At the same time, the PVC resin structure only contains three atoms of carbon (C), hydrogen (H), and chlorine (Cl), and the content of chlorine atoms in the PVC resin composition is as high as 56.8% by mass, which makes it have very good flame retardancy , weather resistance and corrosion resistance, the literature reports that the limiting oxygen index (LOI) of PVC resin is more than 45%, and it belongs to the flame retardant polymer material in the air. Rigid transparent PVC film is made of PVC resin as the base material, compounded with a small amount of stabilizer, processing aid and lubricant,...
