Abstract


Now most of the existing hydrophobic boards are mainly made by coating polyolefin and paraffin wax or coating water-repellency,all of them are not green. So, doing research on green hydrophobic board has practical significance for updating technology, studying new packaging products, saving forest reserves and protecting environment.This project makes sure the ingredient of green anti-blushing agent, evaluate the environmental performance, and prove the performance index through experiment. The paper mainly include as follows:⑴Get wise to wetting mechanization of cardboard, determine the ingredient of green anti-blushing agent with the existing anti-blushing agent and research the mechanization .⑵Refer to the definition of the word of green, define the green anti-blushing agent, and evaluate the environmental conservation of anti-blushing agent with the existing evaluation methodology, confirm the evaluation index of hydrophobic property and moisture resistance.⑶According to the result, make hydrophobic board-sampling, test static water wetting angle 70.52°and 77.24°and water absorption rate 12.65 and 16.32,and the mechanical property——tensile strength 98.26N and 165.03N and elongation at break 24.8% and 29.2%, compare uncoated board and coated board to proving the property of hydrophobic boards. The result proved that this hydrophobic board has good property in hydrophobic and certain effect in improving strength.⑷Through analyzing the influencing factor of the production quality of coated board, determine the productive technology and main working procedure of hydrophobic corrugated board.
