Abstract
The invention discloses a flame-retardant bimodal polyethylene composite material which comprises the following components in parts by weight: 50-85 parts of bimodal polyethylene, 10-40 parts of flame retardant, 0.2-1.0 part of thermal stabilizer, 0.1-1.0 part of processing assistant, 0.1-10 parts of functional assistant and 0-30 parts of filling modifier. The flame-retardant polyethylene prepared by the method provided by the invention has favorable processability; under identical conditions, the injection-molding pressure of the flame-retardant polyethylene is only one-third of common polyethylene, and the use of the product is not affected when the thickness of product is reduced, thereby greatly saving energy consumption on production, saving raw materials and conforming to the development trend of conservation-oriented society; and in addition, the preparation method is simple and satisfies the requirement for industrial production.
Description
Technical field
The present invention relates to a kind of fire-retardant bimodal polyethylene matrix material and preparation method thereof, can be used for electrical package and other modified poly ethylene matrix materials that combustionproperty of material is had relatively high expectations and preparation method thereof.Belong to the high molecule alloy material field.
Background technology
Polyethylene, has in daily life and industrial and agricultural production widely and uses, as food product pack, electrical package, tubing, electric wire etc. because of it has good toughness, electrical insulating property and workability as one of five big general-purpose plastics.Along with the continuous development of polyolefin catalyst and production technique, the poly new variety with different qualities constantly are developed, and bimodal polyethylene is exactly one of them.
The characteristic feature of bimodal polyethylene product is that the polymeric chain in the molecule is divided into low relative molecular mass and high molecular weight two portions, the molecular weight distribution of each polymeric chain is all narrow, but the distribution of total molecular weight of polymer presents wide bimodal form.The harmony that this relative molecular mass distributes makes bimodal polyethylene possess good mechanical property and processing characteristicies such as melt strength height, good heat resistance, good rigidly, creep resistance simultaneously.
Different with common blended polyethylene, the high molecular part and the low molecular weight part of bimodal polyethylene have realized uniform mixing on the molecule rank, and the polyethylene of two kinds of different relative molecular weights has only been realized the mixing on the macroscopic view by twin screw, be difficult to reach the mixing on the microcosmic, therefore on physicals and processing characteristics less than same other bimodal polyethylene of level.
