Abstract

The invention belongs to the field of an organic high-molecular compound, and particularly relates to a PP(Propene Polymer)-PE(Poly Ethylene) alloy and a preparation method thereof. The PP-PE alloy is prepared from the following raw materials including PP, PE, titanium dioxide, rectorite, thiourea, wood fiber, a titanate coupling agent, sulfonated zinc polystyrene and maleic anhydride-glycidyl methacrylate bimonomer grafting high-density polyethylene. The preparation method comprises the following steps of A, weighing the titanium dioxide, the rectorite, the thiourea and the wood fiber according to the weight parts; putting the materials into a high-speed mixing machine; performing dispersion and mixing; and obtaining a mixture A; B, adding the titanate coupling agent and the sulfonated zinc polystyrene into the mixture A obtained in the step A in a spraying way to obtain a mixture B; and C, adding the mixture B obtained in the step B into an extrusion machine, and performing plasticization, fusion, compounding, machine head extrusion, strip pulling, cooling, pelletizing, drying and packaging to obtain the PP-PE alloy. The prepared PP-PE alloy has excellent mechanical performance, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the field of organic polymer compounds, in particular to a PP-PE alloy and a preparation method thereof. Background technique [0002] Polymer alloy materials are a class of new materials with high performance, functionalization and specialization obtained by physical blending or chemical grafting. Polymer alloy material products can be widely used in automobiles, electronics, precision instruments, office equipment, packaging materials, building materials and other fields. [0003] It can improve or increase the performance of existing plastics and reduce costs, and has become one of the most active varieties in the plastics industry, growing very rapidly. With the sustained and rapid development of my country's economy, the demand potential of my country's plastic alloy market is huge in the next few years, especially the rapid growth of electronic communications, automobiles, and construction industries, which will drive th...
