Problems solved by technology

[0002] At present, the materials used for extrusion and compounding in the extrusion compounding equipment of the plastic compound flexible packaging industry are usually plastic pellets, and these materials are petroleum by-products. However, my country’s oil resources are in short supply and the price of oil is often bullish, causing the price of petroleum by-products to also continue to rise. Leads to high production costs and wastes energy

Embodiment Construction

[0009] Principle of the present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0010] The present invention properly reduces the amount of plastic pellets on the basis of retaining the basic components of plastic pellets, the compound material used for extrusion, and adds non-plastic substances in an appropriate amount, that is, plastic pellets and non-plastic substances constitute the filler of the present invention. The non-plastic material is granular, with calcium carbonate CaCo formed by mechanical grinding 3 As the main component, a small amount of LDPE, coupling agent and dispersant are added, and they are pre-mixed with plastic pellets in a certain proportion and extruded by extrusion equipment.

[0011] The present invention works like this in the extrusion equipment: after the extrusion equipment stirs the filler of the present invention with the plastic pellets to be used such as LDPE or PP in a certain proportio...

Abstract

The present invention discloses one kind of stuffing for extrusion compounding and aims at reducing plastic consumption. The stuffing has the basic plastic components maintained, and added pellet comprising mechanically ground calcium carbonate powder as main component and small amount of LDPE, coupling agent and dispersant in certain proportion. The stuffing is applied in extruding soft plastic packing material for food, etc. and has raised physical performance, lowered production cost and saving in energy.

Description

1. Technical field [0001] The invention relates to an improvement of extruded composite materials belonging to the industry of plastic composite flexible packaging. 2. Background technology [0002] At present, the materials used for extrusion and compounding in the extrusion compounding equipment of the plastic compound flexible packaging industry are usually plastic pellets, and these materials are petroleum by-products. However, my country’s oil resources are in short supply and the price of oil is often bullish, causing the price of petroleum by-products to also continue to rise. Lead to high production costs, and waste of energy. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of exorbitant production cost and waste of petroleum resources in existing extrusion compounding equipment in the plastic compounding packaging industry, which all use petroleum by-products—plastic granules. [0004] The object of the p...
