Embodiment 1-5
[0035] According to mass ratio, the content of each component is shown in the following table:
[0036] Table 1. Content table of each component of PVC floor printing ink in embodiment 1-5
[0039] Based on Example 1, the preparation method of Example 1 is as follows,
[0040] Step 1: Weigh the materials, weigh 8kg of vinyl acetate resin, 5kg of acrylic resin, 0.3kg of main dispersant, 0.7kg of auxiliary dispersant, 3kg of heat stabilizer, 3kg of toner, 7kg of cyclohexanone, and 10kg of butyl acetate according to the proportion , 4-methyl-2-pentanone 25kg, butanone 38kg;
[0041] Step 2: Add part of butanone 28.5kg, all of the main dispersant, all of the auxiliary dispersant, all of the toner, and part of the vinyl acetate resin 2.4kg into the stirring container, and stir for 30min at a speed of 1000rpm until the components are evenly mixed , to get a mixture;
[0042] Step 3: Add the mixture obtained by stirring in step 2 into a grinder, and grind it in circulation for 2 hours at a speed of 1000 rpm to obtain a ground semi-finished product;
[0043] Step 4: Add the semi-finished product obtained by grinding in step 3 into the stirring container, and add the rem...

Abstract
The invention discloses high-temperature-resistant PVC floor printing ink and a preparation method thereof, relates to the technical field of plastic floors, and aims to solve the problem that when the temperature of a floor is increased to 135-140 DEG C, the surface of a product is whitened and the like after hot-pressing lamination. According to the technical scheme, the ink is characterized by comprising the following components in percentage by mass: 8-12% of vinyl chloride-vinyl acetate resin, 3-5% of acrylic resin, 0.3-0.7% of a main dispersing agent, 0.3-0.7% of an auxiliary dispersing agent, 1-3% of a thermal stabilizer, 3-7% of toner, 3-7% of cyclohexanone, 10-16% of butyl acetate, 15-25% of 4-methyl-2-pentanone and 35-45% of butanone. After the acrylic resin with a high heat deformation temperature (about 100 DEG C in Heat Distortion Temp) is added, the high-temperature-resistant hot-pressing laminating performance of the PVC floor printing ink is improved; after the hot-pressing resistance and the laminating property are improved, the laminating speed of customers can be increased (the laminating time is shortened), and the productivity is improved; for thicker bottom film pressing, generally, a higher temperature is needed for lamination, so that the hot-pressing resistance of the ink is improved, and adverse phenomena such as high-temperature lamination whitening can be prevented.
Description
technical field [0001] The invention relates to the technical field of plastic floors, in particular to a high-temperature-resistant PVC floor printing ink and a preparation method thereof. Background technique [0002] Plastic floor (PVC floor), the main component is polyvinyl chloride material (PVC). The floor can be made into two types, one is homogeneous and transparent, that is, the pattern material from the bottom to the surface is the same; the other is composite, that is, the top layer is a pure PVC transparent layer, and the bottom layer is added Upper print layer and foam layer. PVC flooring is widely used in all aspects of home and business due to its rich patterns and diverse colors. [0003] The common hot-press lamination temperature for PVC plastic flooring in the industry is 125-130°C. Printing companies want to increase the lamination temperature to increase lamination efficiency. [0004] However, when the temperature was increased to 135-140°C, it was f...
