Embodiment 1

[0031] Example 1: Take 150g of waste polystyrene foam according to the formula, clean it, break it up, put it into a 1000ml three-neck bottle containing 550g of toluene, heat and stir it to 90°C, add 20g of compounding additives, stir evenly, and cool down When the temperature reached 40°C, the AK modified resin was obtained by filtering and discharging; the measured solid content was 32%, and the viscosity was 100 seconds. Take 280g of kaolin and 500g of AK resin, stir and disperse them, put them into a 2L sander and grind them for 3 hours, then check that the fineness reaches ≤15 microns, take them out and put them into a stirring container, add 2g of slip agent and antistatic agent 30g, the control speed is 60 rpm; stir for 30 minutes to make synthetic paper coating. Scratch test on PET synthetic paper film, the effect is good and meets the requirements. According to GB / T13217 "Gravure Plastic Ink Test Method" and GB / T6753.3 "Paint Storage Stability Test Method", the test ...

Embodiment 2

[0032] Example 2: Take 160g of waste polystyrene foam according to the formula, clean it, break it up, put it into a 1000ml three-neck bottle containing 600g of toluene, heat and stir it to 120°C, add 25g of compound additives, stir evenly, and cool down When the temperature reached 40°C, the AK modified resin was obtained by filtering and discharging; the measured solid content was 40%, and the viscosity was 120 seconds. Take 200g of kaolin and 500g of AK resin, stir and disperse them, put them into a 2L sander and grind them for 3 hours, then check that the fineness reaches ≤15 microns, take them out and put them into a stirring container, add 2g of slip agent and antistatic agent 35g, the control speed is 60 rpm; stir for 30 minutes to make synthetic paper coating. The scraping test on PP synthetic paper film has good effect and meets the requirements. According to GB / T13217 "Gravure Plastic Ink Test Method" and GB / T 6753.3 "Paint Storage Stability Test Method", the test r...

Embodiment 3

[0033] Example 3: Take 80 kg of waste polystyrene foam according to the formula, clean and smash it, put it into a 500L reactor with 220 kg of toluene, heat and stir, control the temperature to 100 ° C, add 10 kg of compounding additives, and stir After uniformity, the temperature was lowered to 40°C and the material was discharged to obtain an AK modified resin; the measured solid content was 38%, and the viscosity was 130 seconds. Put 100kg of kaolin and 150kg of AK modified resin into a high-speed disperser to disperse evenly, then transfer to a 20L vertical sand mill for grinding, and after 2 to 3 times, check that the fineness reaches ≤15 microns, then transfer to the mixing tank Add 0.1kg of slip agent and 0.12kg of antistatic agent, and stir at a slow speed for 40 minutes to obtain a synthetic paper coating. Put the synthetic paper coating on the ordinary gravure printing machine, and use the PVC film for trial printing, the effect is good and meets the requirements. A...

Abstract

The present invention discloses a synthetic paper paint and preparation and usage thereof, wherein the paint includes, in mass percent, waste polystyrene plastic foam 10-20%, white bole 20-30%, toluene 50-60%, anstatic agent 0.2-0.5%, slipping agent 0.1-0.3% and additive compound 2-3%. The preparation procedure is as following: adding toluene to the polystyrene plastic foam; melting the polystyrene plastic foam in temperature no higher than 150 DEG; then adding additive compound to make AK modified resin; dispersing the white bole with the obtained AK modified resin thoroughly and even, then seat grinding to degree of fineness smaller than or equal to 15micrometre; then dispersing the mixture of slipping agent, anstatic agent and the grinded material even at last to get the synthetic paper paint. Form a printable layer on the synthetic paper surface by the synthetic paper paint to improve synthetic paper printability for convenient of synthetic paper application on general mode of printing and common printing ink, hence expands synthetic paper application range.

Description

technical field [0001] The invention relates to a synthetic paper coating, its preparation method and its application on printing synthetic paper. Background technique [0002] Synthetic paper has a development history of more than 30 years. With the strengthening of global environmental protection awareness, ordinary fiber paper has caused a lot of pollution, which has accelerated the development of synthetic paper. The continuous emergence of new synthetic paper varieties has expanded the application range of synthetic paper. . However, synthetic paper in my country started relatively late and is mainly imported products. Because the printability of these synthetic papers has strict requirements on inks, only expensive special high-grade inks can be used. To make PP, BOPP, PVC, PET, HDPE, ABS, PS and other synthetic papers suitable for general printing methods and general printing inks, expanding the scope of use of synthetic paper is only an idea. [0003] With the rapi...
