Antibacterial coating masterbatch, antibacterial coating woven bag and production method of antibacterial coating masterbatch

Abstract

The invention relates to antibacterial coating masterbatch which comprises 60+ / -4 parts of coating-grade polyethylene aggregates, 30+ / -3 parts of a nano antibacterial agent, 4+ / -1 parts of oxidized polyethlene wax and 6+ / 1 parts of an auxiliary. The production method comprises the following steps: mixing the various raw materials in a material mixing machine at a high speed for 5 minutes; introducing a raw material mixture into a double-screw granulator through vacuum suction; performing melt extrusion, water cooling, air drying, cutting and screening under the temperature of 210 to 270 DEG C, thus obtaining a finished product. The antibacterial rate is up to 99.07-99.62 percent; after the antibacterial coating masterbatch is soaked by one month, the antibacterial rate to various germs is still kept at 94.93 to 98.45 percent; the oxygen penetration amount (cm<3> / m<2>.d.0.1MPa) reaches 825 to 1,090; the contact angle is larger than 150 degrees.

Description

technical field [0001] The invention relates to a woven bag, in particular to an antibacterial coating film masterbatch, an antibacterial coating film woven bag and a production method thereof, belonging to the technical field of packaging materials. Background technique [0002] Since the development of flat wire woven bags in my country in 1966, the products have developed rapidly, and a series of products with various designs and colors and complete specifications and sizes have been formed. At present, plastic woven bags have been widely used in sea, transportation, packaging industrial and agricultural products, and in agricultural product packaging. At present, plastic woven bags have been widely used in aquatic product packaging, poultry feed packaging, covering materials for farms, sunshade for crop planting, windproof, hailproof sheds and other materials. Common products: feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, etc. [0003] I...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that the prior art has at least the following deficiencies: although plastic woven bags bring great convenience to people's lives, the currently produced plastic woven bags do not have an antibacterial function, especially those made with plastic woven bags. Plastic woven bags used for food, feed, and grain packaging are prone to bacteria during the packaging process, and there are food safety problems, and because oxygen and water are easy to permeate, the stored items, especially grains, grains, etc. are easy to deteriorate. Doesn't work well in the sales process
