Abstract

The invention discloses a high fill polyolefin composite film masterbatch and a preparation method thereof. The high fill polyolefin composite film masterbatch comprises the following raw materials in parts by mass: 70-80 parts of inorganic filler, 13-27 parts of high polymer resin, 0.5-1.5 parts of coupling agent, 0.5-1 part of lubricant, 0.1-0.2 parts of antioxidant and 0-0.2 parts of compatilizer. The masterbatch is prepared by the traditional plastics processing machine, the production technology is simple, the filling quantity of inorganic powder is large and can reach 80%, the price is low, the masterbatch can be directly used for extruded blow molding, extruded tape casting and extruded traction forming to prepare films in various thicknesses. The prepared films are green and environment-friendly new materials, have good water resistance, moisture protection, oil resistance, physical properties, printability and writability, and can serve as materials such as packaging paper, letter paper and wallpaper.

Description

1. Technical field [0001] The invention relates to a highly filled polyolefin composite film masterbatch, in particular to a highly filled polyolefin composite film masterbatch and a preparation method thereof. 2. Technical background [0002] The plastic film is composed of polymer resins, among which high-density polyethylene, low-density polyethylene, linear low-density polyethylene and polypropylene are the main ones. With the price increase of oil, the cost of raw resin has increased, but the price of finished products has remained at a relatively stable level, causing the plastic film industry to fall into trouble. [0003] In order to reduce the cost of the product, inorganic fillers are usually added to the resin, at the expense of part of the mechanical properties of the plastic film. However, at present, the filling amount of inorganic fillers in films in China is basically below 30%, and it is difficult to form them if the filling amount is above 30%, resulting i...
