Problems solved by technology

The material selection of these macroscopic multi-layer composite materials not only consumes a lot of scarce energy and aluminum resources, but also causes pollution to the ecological environment.
Even when recycled, disposal costs are quite expensive
The processing technology and processing equipment are relatively complicated. Generally, multiple processing equipment must be used to process and produce. Due to the complex composition of materials and processing technology, the price is also high.

Embodiment 1

[0008] Polyethylene resin, ratio: 75%, the proportion of polyethylene resin: high-density polyethylene 30%, low-density polyethylene 30%, linear low-density polyethylene 15%;

[0009] Aromatic nylon chooses nylon 6, ratio: 16%;

[0010] Montmorillonite NB901, ratio: 3%;

[0011] Choose ethylene-vinyl acetate copolymer, ratio: 6%.

[0012] The above-mentioned components are mixed and granulated, and then compressed into a sheet using an extrusion calender to form a microscopic layered composite structure sheet, as shown in the attached electron microscope photo of the product.

Embodiment 2

[0014] Polyethylene resin, ratio: 85%;

[0015] Aromatic nylon chooses nylon 66, ratio: 5%;

[0016] Montmorillonite NB908, ratio: 3%;

[0017] Choose glycerol methacrylate graft, proportion: 7%. All the other are with embodiment 1.

Embodiment 3

[0019] The proportion of polyethylene resin is 80%, the proportion of nylon 1010 is 8%, the proportion of montmorillonite NB901 is 4%, and the proportion of glycerin methacrylic acid graft is 8%. Color masterbatch is also added in the batching, and the rest are the same as in Example 1.

Abstract

The invention relates to overall-plastic microcosmic layered composite material with the weight proportion of material as: 75~85% polyvinyl resin composed of HDPE, LDPE, and LLDPE, 5~16% aromatic nylon selected one between nylon 6, nylon 66 and nylon 1010, 3~8% montmorillonite selected one between NB901 and NB908, and 5~13% grafts selected one between ethylene-vinyl acetate copolymer, polyvinyl maleic anhydride grafts, and glyceryl methacrylate. Wherein, the preparation method comprises: using material to mix and granulate, using extrusion calendar to tablet and form for one time. The product can not only fit to package request for grease, organic solvent, etc, but also needs no special device, and is photodegradated.

Description

1. Technical field: [0001] The invention relates to an all-plastic microscopic layered composite material and a preparation method thereof, which are applied to the hose packaging of water-emulsion-based paste substances. 2. Background technology: [0002] At present, the traditional grease and organic solvent hose 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. The material selection of these macroscopic multilayer composite materials not only consumes a lot of scarce energy and aluminum resources, but also causes pollution to the ecological environment. Even when recycled, disposal costs are quite expensive. The processing technology and processing equipment are relatively complicated. Generally, multiple processing equipment must be used to process and produce. Due to the complexity of the material composition a...
