Problems solved by technology

In order to meet the packaging requirements of various water-emulsion-based paste substances and their products such as toothpaste, cosmetics, and dairy foods, these macroscopic multilayer composite materials are relatively complicated in terms of material selection, processing technology, and processing equipment, and generally must use Multiple processing equipment can be processed and produced, which not only consumes a lot of scarce energy and aluminum resources, but also is difficult to degrade after use and disposal, causing environmental pollution that affects ecology
Even when recycled, disposal costs are quite expensive
At the same time, due to the complex composition and processing technology of the material, its price is also high.

Embodiment Construction

[0005] Get polyethylene resin (PE): 50 kilograms, modified calcium carbonate (CaCO3): 8 kilograms, ethylene-vinyl acetate copolymer resin (EVA): 3 kilograms, titanium dioxide (TiO2): 4 kilograms, photodegradation aid (HD--1): 3 kg, polyethylene wax (PE--WAX): 2 kg, titanate coupling agent (NDZ--130): 4 kg, auxiliary coupling agent (DL): 0.7 kg, Paraffin wax (WAX): 3 kg, zinc stearate (ZnSt): 4 kg, modified magnesium carbonate (MgCO3): 12 kg, optical brightener: 0.7 kg, white oil (liquid paraffin): 2 kg, ethylene Ethyl bis stearamide (EBS): 0.6 kg, ethylene-vinyl alcohol copolymer (EVOH): 3 kg. After mixing and stirring, under the shear action of a 1:48 twin-screw extruder (temperature controlled at 180 degrees to 200 degrees) and the interface stabilization of compatible polymers, the barrier polymers are first dispersed to form a stable The near-spherical multi-microphase structure, and then under the orientation and stretching of the die and roller of the calender, a multi-...

Abstract

A photodegradable plastic soft tube used for packing the water or cream-based paste is proportionally prepared from polyethen resin, modified calcium carbonate, ethene-vinyl acetate copolymer resin, titanium oxide powder, photodegradant, polyethene wax, titanate coupling agen, cocoupling agent, paraffin wax, zinc stearate, modified magnesium carbonate, etc.

Description

technical field [0001] The invention relates to a hose packaging functional material, in particular to a novel photodegradable all-plastic water-emulsion-based hose packaging functional material. Background technique [0002] At present, the traditional water-emulsion-based paste-like material tube packaging materials widely used in the market, such as aluminum-plastic composite materials, all-plastic multi-layer co-extrusion composite materials, etc., are all macroscopic multi-layer composite materials. In order to meet the packaging requirements of various water-emulsion-based paste substances and their products such as toothpaste, cosmetics, and dairy foods, these macroscopic multilayer composite materials are relatively complicated in terms of material selection, processing technology, and processing equipment, and generally must use Multiple processing equipment can be processed and produced, which not only consumes a lot of scarce energy and aluminum resources, but als...
