Embodiment Construction

[0028] 1. Preparation of antibacterial plastic masterbatch

[0029] The purpose of preparing antibacterial plastic masterbatch is to

[0030] 1) Reduce nano-silver inorganic antibacterial agents that will be oxidized and blackened at a temperature higher than 100°C. (due to the formation of silver oxide)

[0031] 2) A small amount of nano-silver can be better dispersed in the plastic pellets.

[0032] Composition (weight ratio) of antibacterial plastic masterbatch:

[0033] Linear Low Density Polyethylene LLDPE 50-65

[0034] Low Density Polyethylene LDPE 10-18

[0035] Antimicrobial 20-20

[0036] Polyethylene wax 2.5-3.5

[0037] Zinc stearate 0.8-1.2

[0038] Titanium dioxide 1.6-2.4

[0039] Considering that the antibacterial masterbatch is easy to calculate when adding materials, we usually use an antibacterial masterbatch formula with an antibacterial agent content of 25%.

[0040] Examples of antibacterial plastic masterbatch production are as follows:

Abstract

An antibacterial and water-permeable plastic pellet for film, which is composed of linear low-density polyethylene LLDPE and low-density polyethylene LDPE as a matrix resin, and is kneaded by adding inorganic powder antibacterial masterbatch, elastomer resin, lubricant, and antioxidant It is made by extruding, heating, plasticizing and granulating. The antibacterial, breathable and waterproof film can be prepared by using the pellets to form a film and then biaxially stretch it. It can be widely used in baby diapers, dry mesh for women's sanitary napkins, disposable gloves, masks, food packaging and hygienic medical materials.

Description

technical field [0001] The invention belongs to a kind of plastic pellets and a preparation method thereof, in particular to an antibacterial, breathable and waterproof plastic for film which is processed with polyethylene resin as a matrix and added with additives such as elastomer resin, antibacterial agent and inorganic filler. Pellets and methods for their preparation. Background technique [0002] The development and application of antibacterial waterproof and breathable pellets has built a green barrier for the protection of human health, which is of great significance for improving the living environment of human beings, reducing diseases, and protecting the health of the whole people. [0003] With the implementation of a series of national green environmental protection and resource conservation policies, new plastics are gradually replacing traditional natural materials, wood and metal materials, and are favored by people for their excellent performance and rich co...
