Abstract

The invention discloses a packing bag coating and a preparation method thereof. The packing bag coating comprises the following raw materials by weight: 1 to 2 parts of tung oil, 1 to 2 part of tung oil anhydride, 0.3 to 0.5 part of a silane coupling agent, 20 to 40 parts of calcium carbonate, 15 to 25 parts of polypropylene, 10 to 20 parts of permethrin, 5 to 10 parts of cellulose base fiber, 5 to 10 parts of alanine, 3 to 7 parts of talcum powder, 2 to 5 parts of nano titanium dioxide, 1 to 2 parts of isobutyl methacrylate, and 5 to 7 parts of rosin resin. The preparation method comprises the steps of grinding, modifying, stirring and drying. After being treated with the packing bag coating, the surface of a material is excellent in lipophilic-hydrophobic property; moreover, rosin resin has a forming and enveloping function, and permethrin has corrosion-resistant and insect-killing functions, so that the coating is resistant to corrosion.

Description

technical field [0001] The invention relates to the field of packaging coatings, in particular to an anti-corrosion coating for packaging bags and a manufacturing method thereof. Background technique [0002] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, and it is one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water is only 0.01%, and the molecular weight is about 80,000-150,000. Good formability, but due to large shrinkage, thick-walled products are easy to sag, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product has good gloss and is easy to color. Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The chemical stability of polypropylene is very good, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, it is ...
