Problems solved by technology

[0002] Laundry powder is a necessity for washing in daily life. It is usually packaged in a plastic bag to prevent leakage or deliquescence of the laundry powder. During the use and transportation of the laundry powder, it is usually dropped and piled up at random. Therefore, the laundry powder packaging bag must be It has high anti-drop performance and strength, otherwise it is easy to break and cause the powder in it to be missed, but the tear strength of the existing packaging bags is low, which cannot meet the demand, and when the washing powder is used in different fields and occasions, it may withstand Exposure to the sun for a long time, and may be in a high temperature environment for a long time, it is easy to cause the washing powder packaging bag to age and become brittle, easy to tear, and the washing powder will spill out

Embodiment 1

[0019] The specific preparation process of the antioxidant is as follows: ①Add 10g of mercaptosuccinic acid into 100mL of water and stir to dissolve, then add 16.7g of thionyl chloride solution to it, raise the temperature to 70-80°C for reflux reaction for 10-12h, and then dissolve the obtained product The solution was evaporated at 90°C. At this time, the unreacted thionyl chloride solution decomposed, and the solvent water evaporated at the same time to obtain mercaptosuccinyl chloride; ②Add 1.68g of mercaptosuccinyl chloride prepared in step ① and 50mL of water into the reaction vessel, stir to dissolve , and then add 2.88g of 1-piperidinethiocarbonylamine to it, raise the temperature to 60-65°C for reflux reaction for 15-16h, and then obtain the antioxidant through vacuum distillation.

Embodiment 2

[0021] The high-strength hydrophobic film is made by adding high-density polyethylene, low-density polyethylene, the antioxidant, dispersant, and surfactant prepared in Example 1 according to the mass ratio of 100:12.3:0.73:2.16:0.86 after extrusion Casting to obtain a high-strength hydrophobic film.

Embodiment 3

[0023] The preparation method of the high-strength hydrophobic film is the same as in Example 2, and the antioxidant prepared in Example 1 used in Example 2 is replaced by 1-piperidinethiocarbonylamine.

Abstract

The invention discloses a composite high-strength washing powder packaging bag. The specific preparation process of the packaging bag is as follows: add petroleum ether, Tween-80 and dodecylbenzenesulfonic acid to the prepared polymer, stir and mix for 20 ‑30min, then the mixture is evenly coated on the surface of the high-strength hydrophobic film, and immediately after the spraying is completed, a layer of high-strength hydrophobic film is compounded on the surface of the coating layer to obtain a three-layer sandwich plastic film. Curing for 2-3 hours to obtain a high-strength drop-resistant plastic film, and then prepare the high-strength drop-resistant plastic film into a packaging bag. The intermediate buffer layer of the packaging bag of the present invention contains a large amount of siloxane bonds, thereby improving the thermal stability of the plastic bag, so that when the packaging bag is aged at high temperature, its breaking strength does not change much, and further improves the thermal stability of the packaging bag. The thermal aging resistance and light aging resistance make the prepared packaging bag resistant to high temperature aging.

Description

technical field [0001] The invention belongs to the field of washing powder packaging film preparation and relates to a composite high-strength washing powder packaging bag. Background technique [0002] Laundry powder is a daily washing necessity. It is usually packaged in a plastic bag to prevent leakage or deliquescence of the laundry powder. During the use and transportation of the laundry powder, it is usually dropped and piled up at will. Therefore, the laundry powder packaging bag must be It has high anti-drop performance and strength, otherwise it is easy to break and cause the powder in it to be missed, but the tear strength of the existing packaging bags is low, which cannot meet the demand, and when the washing powder is used in different fields and occasions, it may withstand Exposure to the sun for a long time, and may be in a high temperature environment for a long time, will easily cause the washing powder packaging bag to age and become brittle, easy to tear,...
