preparation example Construction

[0026] The invention provides a kind of mixed wax made from printing ink and its preparation method, which is realized by the following steps:

[0027] Step 1. Preparation of water phase

[0028] In parts by weight, add 1000 parts of water and 0.5 part of polyvinyl alcohol into the pressure reactor, and stir evenly.

[0029] Step 2. Preparation of oil phase

[0030] In parts by weight, mix 100 parts of PE wax and 4 parts of perfluoroalkyl ethyl acrylate monomer, add 0.2 parts of peroxide initiator, and stir evenly.

[0031] Step 3. Suspension Polymerization

[0032] Add the oil phase solution prepared in the beaker in step 2 to the pressure reactor equipped with the prepared water phase in step 1, stir slowly and then quickly, and then react from 50°C for 10, discharge after the reaction, and wash with water Microspheres until the water is clear to obtain the product.

[0033] Step 4. Blending and crushing

[0034] 94 parts of the surface-grafted polyethylene wax powder o...

Embodiment 2

[0036] 85 parts of the surface-grafted polyethylene wax powder obtained in step 3 are then mixed with 15 parts of PTFE powder, ground and crushed by weight in a fluidized bed jet mill to obtain the patented product. The number is SX-2.

Embodiment 3

[0038] 98 parts of the surface-grafted polyethylene wax powder obtained in step 3 are then mixed with 2 parts of PTFE powder, ground and crushed by weight in a fluidized bed jet mill to obtain the patented product. The number is SX-3.

Abstract

The invention provides mixed wax for printing ink and a preparation method for the mixed wax. The preparation method comprises the following steps: adding pure water and a polymerization inhibitor into a reaction kettle, adding a certain amount of dispersing agent, a proper amount of initiator and a certain amount of PE (polyethylene) wax / perfluoroalkylethyl acrylate mixture, raising the temperature to reaction temperature, and performing drying and discharging to obtain surface-grafted polyethylene wax powder after reaction; mixing the polyethylene wax powder and PTFE (polytetrafluoroethylene) powder, and pulverizing and crushing the mixture in a pulverizer to obtain a product. According to the mixed wax and the preparation method for the same, a small amount of perfluoroalkylethyl acrylate monomers with double bonds are introduced into a polyethylene wax skeleton as grafting monomers to improve the compatibility of a PE / PTFE polymer, and complete contact and uniform dispersion in a crushing mixing process can be ensured; in addition, multiple carbonyls are introduced into perfluoroalkylethyl acrylate to improve the intermolecular polarity of the mixed wax, damage the crystallinity of printing ink resin and maintain the polarity of the printing ink, so that the hue error resistance and scuffing resistance of the printing ink are improved.

Description

technical field [0001] The invention relates to a preparation method of mixed wax, in particular to a mixed wax made from printing ink and a preparation method thereof. Background technique [0002] Adding PTFE wax to the polymer coating can improve the non-adhesiveness of the countertop or the conveyor belt for conveying sticky items, and the sticky items will not stick to the waxy coating. PTFE wax is added to mineral oil or synthetic oil as a thickener to prepare special grease. Because PTFE wax has the characteristics of high and low temperature resistance, corrosion resistance and low friction, the thickened grease also has these valuable properties correspondingly, and can be used in special occasions with harsh environments. Adding PTFE wax into the ink can improve the non-adhesiveness of the ink and is suitable for high-speed printing. PTFE wax is white and can be added to any ink without affecting the color effect of the ink. [0003] EP-A-0890619 discloses, inte...
