specific Embodiment approach 1

[0007] The specific embodiment one: the preparation method of the polyvinyl chloride film used for inkjet painting in this embodiment is realized according to the following steps: one, 5 to 30 parts of nano-inorganic particles and 3 to 20 parts of epoxy soybean oil are packed into the mixer, and Mix at a speed of 500-1000r / min for 5-60 minutes to obtain a mixture; 2. Mix 100 parts of polyvinyl chloride resin, 30-80 parts of tris(2-ethyl)hexyl trimellitate, 0.1-5 parts of Antioxidant, 0.1-30 parts of titanium dioxide and 0.1-5 parts of ultraviolet absorber are added to the mixture, and mixed at a speed of 500-1000r / min for 10-60 minutes to obtain a mixture; 3. Put the mixture into PVC The calendering production line is used to make a polyvinyl chloride film, which is a polyvinyl chloride film for inkjet painting; wherein the nano-inorganic particles in step 1 are nano-calcium carbonate or nano-silicon dioxide.

[0008] Both antioxidants and ultraviolet absorbers currently used ...

specific Embodiment approach 2

[0009] Specific embodiment two: the difference between this embodiment and specific embodiment one is that in step one, 15 parts of nano-inorganic particles and 5 parts of epoxidized soybean oil are put into the mixer, and mixed at a speed of 800 r / min for 20 min. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0010] Specific embodiment three: the difference between this embodiment and specific embodiment one is that in step two, 100 parts of polyvinyl chloride resin, 50 parts of tris(2-ethyl)hexyl trimellitate, 1 part of antioxidant Agent, 5 parts of titanium dioxide and 1 part of ultraviolet absorber were added to the mixture, and mixed at a speed of 800r / min for 30min. Other steps and parameters are the same as those in Embodiment 1.

Abstract

A preparation method of polyvinyl chloride film for spray painting relates to a preparation method of a polyvinyl chloride film. The method resolves problems of complex technology, high cost, and low plasticizing efficiency of plasticizer and poor spray painting effect of polyvinyl chloride film for spray painting of polyvinyl chloride film precipitated from low plasticizer of existing preparation. The method is that: 1. Inorganic nano-particles and epoxy soybean oil are mixed to gain a mixture; 2. Polyvinyl chloride resin, triethyl trimellitate (2-ethyl), antioxidant, titanium pigment and ultraviolet absorber are added into the mixture to gain mixing materials; 3. The mixing materials are filled into a PVC calendaring production line to produce polyvinyl chloride film, namely, the polyvinyl chloride film for spray painting. The invention is characterized by simple technology, low cost, high plasticizing efficiency and good effect of spray painting.

Description

technical field [0001] The invention relates to a preparation method of a polyvinyl chloride film. Background technique [0002] The plasticizer in the polyvinyl chloride (PVC) film for inkjet painting not only endows the PVC film with a certain degree of flexibility and mechanical strength, but also has a certain impact on the quality of the inkjet painting picture. PVC film with high plasticizer content has higher color saturation and gloss, and plasticizer with low plasticizing efficiency often has poor inkjet effect. Plasticizers are easily precipitated by the environment and migrate to the surface of the film, which will affect the absorption of ink, resulting in a decrease in the definition of the spray painting, uneven color, and reduced gloss. Most of the new plasticizers are polyester compounds, but the plasticizing efficiency of polyester compounds is low. In order to obtain a good plasticizing effect, a large amount must be added, which increases the cost. Moreov...
