Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that since the label still has residual temperature after printing, the ink on the surface of the label is easy to fade when heated, so that the faded ink is easy to stick to the adjacent PVC sun visor, and, Since the PVC sun visors are stacked together, the label is under the pressure of the adjacent PVC sun visor, which makes the faded ink further adhere to the adjacent PVC sun visor, thus affecting the appearance of the finished PVC sun visor

Embodiment 1-4

[0052]A label that does not adhere to PVC, comprising a bottom paper layer, a glue layer, a label paper layer and an ink layer arranged sequentially from bottom to top; the ink layer is made of the following raw materials by weight:

[0053] Color pigment; 1-(4-nitrophenylazo)-2-naphthol; nano titanium dioxide; polysilazane; defoamer; diluent.

[0054] The preparation method of the ink layer is as follows: first mix 1-(4-nitrophenylazo)-2-naphthol, nano-titanium dioxide and polysilazane, stir at a speed of 100r / min for 20 minutes until uniform, Obtain a mixture; then add color pigments, defoamers and diluents to the mixture in sequence, stir at a speed of 60r / min for 30 minutes until uniform, and obtain an ink; finally print the prepared ink on the surface of the label paper layer , forming an ink layer.

[0055] The dosage of each raw material of the ink layer is shown in Table 2, and the dosage unit of each raw material in Table 2 is kg.

[0057]

Embodiment 5

[0059] The difference from Example 4 is that 28kg of polyethylene wax and 9kg of dioctyl sodium sulfosuccinate were mixed uniformly in advance, and then added to the mixture and mixed uniformly with other raw materials.

Embodiment 6

[0061] The difference from Example 4 is: 14kg of polyethylene wax and 20kg of dioctyl sodium sulfosuccinate were mixed uniformly in advance, and then added to the mixture and mixed uniformly with other raw materials.

Abstract

The invention relates to the field of labels, and particularly discloses a label not adhered to PVC (polyvinyl chloride), which comprises a bottom paper layer, a glue layer, a label paper layer and an ink layer which are sequentially arranged from bottom to top, the ink layer is prepared from the following raw materials in parts by weight: 2-9 parts of color pigment; 13 to 22 parts of 1-(4-nitrophenyl azo)-2-naphthol; 20 to 48 parts of nano titanium dioxide; 55 to 120 parts of polysilazane; 6 to 15 parts of a defoaming agent; and 10-26 parts of a diluent. The PVC sun shield has the effect that printing ink on the label is not prone to being adhered to the PVC sun shield.

Description

technical field [0001] This application relates to the field of labels, more specifically it relates to a label that does not stick to PVC. Background technique [0002] Self-adhesive label is a more commonly used label form, also called self-adhesive label material. It is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the base paper. After printing, die-cutting and other processing, it becomes a finished label. [0003] At present, self-adhesive labels with warning words are usually pasted on the sun visor of the car to remind people to pay attention to safety. In the production process of PVC sun visors, the labels with warning words are usually pasted on the PVC sun visors first, and then a number of pasted PVC sun visors are stacked together, and finally the finished PVC sun visors are stored in the warehouse. [0004] In view of the above-mentioned related technologies, the i...
