Problems solved by technology

Covering plastic PP film is not only expensive, but also brings great difficulties to the repeated use of packaging, while the dispersion medium of oily calender oil is toluene or ethanol, which are organic solvents with great volatility. There are great toxic effects in actual operation or in the use of packaging
Some water-based calender oils on the market have low gloss, inconvenient operation, and poor wear resistance, especially because the temperature of the calendered steel coil is between 90-100 degrees, so it is difficult to remove the film from the steel coil

Embodiment 1

[0026] (1) 60 parts of thermoplastic acrylic emulsion and 30 parts of thermoplastic acrylic resin were dispersed for 10 minutes at room temperature under the premise of using 2 parts of isobutanol as an initiator to prepare No. 1 component (500 rpm).

[0027] (2) Mix 70 parts of deionized water into 30 parts of polyethylene wax and disperse at high speed for 30 minutes (1500 rpm) to prepare No. 2 component.

[0028] (3) Add No. 2 component in an addition amount of 0.7 to No. 1 component in a proportion of 92 parts, fully disperse for 30 minutes (500 rpm), add 0.3 parts of a polymeric water-based wetting agent, and then disperse for 20 minutes (600 rpm) and then add 2 parts of water-based anti-wear agent polytetrafluoroethylene wax, and add 5 parts of water at the same time, after dispersion for 20 minutes (800 rpm), static and stable for 20 minutes, filter and package.

Embodiment 2

[0030] (1) 70 parts of thermoplastic acrylic emulsion and 20 parts of thermoplastic acrylic resin were dispersed for ten minutes at room temperature under the premise of using 2 parts of isobutanol as an initiator to prepare No. 1 component (500 rpm).

[0031] (2) Mix 70 parts of deionized water into 30 parts of polyethylene wax and disperse at high speed for three minutes (1500 rpm) to generate No. 2 component.

[0032] (3) After adding No. 2 component in an addition amount of 0.5 to No. 1 component in a proportion of 92 parts and fully dispersing it for 30 minutes (500 rpm), add 0.5 part of a polymeric water-based wetting agent, and then disperse 20 minutes (600 rpm), add 2 parts of water-based anti-wear agent polypropylene wax, add 5 points of water at the same time, disperse for 20 minutes (800 rpm), stabilize for 20 minutes, filter and pack.

Embodiment 3

[0034] (1) 65 parts of thermoplastic acrylic emulsion and 23 parts of thermoplastic acrylic resin were dispersed for ten minutes at room temperature under the premise of using 3 parts of isobutanol as an initiator to prepare No. 1 component (500 rpm).

[0035] (2) 60 parts of deionized water was mixed with 25 parts of polyethylene wax and dispersed at high speed for three minutes (1500 rpm) to generate No. 2 component.

[0036] (3) Add No. 2 component in an addition amount of 0.6 to No. 1 component in a ratio of 85 parts and fully disperse it for 30 minutes (500 rpm), add 0.2 parts of a polymeric water-based wetting agent, and then disperse 20 minutes (600 rpm), add 3 parts of water-based anti-wear agent polypropylene wax, and add 7 parts of water at the same time, disperse for 20 minutes (800 rpm), stabilize for 20 minutes, filter and pack.

Abstract

The invention relates to water-based buffing oil for paper and a preparation method thereof. In the invention, thermoplastic acrylic emulsion as the main film forming emulsion, thermoplastic acrylic resin as dispersion resin and isobutanol as an initiator are dispersed at high speed at normal temperature, then other additives are gradually added, ployethylene wax is hydrolyzed by de-ionized water to generate a release agent with high temperature resistant effect, and then the release agent is added to the formula. The water-based buffing oil for paper obtained in the invention has little toxicity and odor, small environment pollution, high luster, especially good high temperature resistance and demolding property, and good stability in storage and use, and can be widely used for glazing and buffing finishing of the surfaces of various paper products.

Description

technical field [0001] The invention relates to a chemical coating, in particular to a calendering oil for paper. Background technique [0002] At present, in order to achieve a good surface decoration effect in the packaging industry, the surface of the packaging will be covered with a plastic PP film or an oil-based calendering oil will be used to decorate the surface. Laminating plastic PP film is not only expensive, but also brings great difficulties to the repeated use of packaging. The dispersion medium of oily calender oil is toluene or ethanol, which are organic solvents with great volatility. There are great toxic effects in actual operation or in the use of packaging. Some water-based calendering oils on the market have low gloss, inconvenient operation, and poor wear resistance, especially because the temperature of the calendered steel coil is between 90-100 degrees, so it is difficult to release the film from the steel coil.
