Abstract

The invention relates to a preparation process for a polyvinyl alcohol film. The polyvinyl alcohol film is prepared from polyvinyl alcohol, nano-scale rare earth, ethyl vanillin, Tween 80 and castor oil. The preparation process is carried out according to the following process steps: polyvinyl alcohol is put in a water bath with the temperature of 85-95 to prepare a polyethylene film solution; ethyl vanillin and the castor oil are mixed uniformly to obtain a substance A for standby use; the nano-scale rare earth and Tween 80 are mixed uniformly to obtain a substance B for standby use; the substance A is added to the polyethylene film solution, and the mixture of the substance A and the polyethylene film solution is uniformly mixed to obtain a substance C for standby use; the substance B isadded to the substance C, uniform mixing is performed, and then the mixture of the substance B and the substance C is applied to a glass plate to prepare the polyvinyl alcohol film. The invention provides the polyvinyl alcohol film preparation process which is reasonable in process and provided with suitable aids to improve the antibacterial properties of plastics.

Description

technical field [0001] The invention relates to a preparation process of a polyvinyl alcohol film, which belongs to the technical field of composite materials. Background technique [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition or polycondensation of monomers, commonly known as plastics or resins. It can freely change its composition and shape. It is composed of synthetic resins and fillers, Plasticizer, stabilizer, lubricant, colorant and other additives. [0003] Plastics are widely used in many fields due to their advantages of low price, easy molding, chemical corrosion resistance and easy coloring; but at the same time, plastics themselves do not have antibacterial and anti-oxidation properties, so they are greatly restricted in the field of life technology. Therefore need to improve. Contents of the invention [0004] The purpose of the present invention is to provide a preparation process of a polyvinyl alcohol film with a ...
