Embodiment 1

[0029] Weigh nylon 6 as 30%, polylactic acid 57%, ethylene-methyl acrylate-glycidyl methacrylate random terpolymer 6%, phthalates 4%, calcium dichloride 10 kg of 3% mixture. The polylactic acid and nylon 6 are dried for 2 hours first, and then nylon 6, calcium dichloride is blended uniformly in a high-speed mixer with a rotation speed of 800 rpm, and the mixture is added to the twin-screw extruder to melt Extrusion granulation, the extrusion temperature is 200~250℃. The extruded material is dried and blended with polylactic acid, ethylene-methyl acrylate-glycidyl methacrylate random terpolymer and phthalates again in a high-speed mixer at a rotation speed of 800 rpm It is uniform, and then added to the twin-screw extruder again for melt extrusion granulation, and the extrusion temperature is 190-220°C. The material obtained by re-extruding is dried and then added to the injection molding machine to inject the sheet. Then carry out the natural degradation experiment. Natural...

Abstract

The invention relates to a polylactic acid / nylon 6 compound metal biodegradation material and preparation method. The polymer blend compound metal comprises by weight the materials: 30%-50% of nylon 6, 30%-50% of polylactic acid, 5%-10% of compatibilizer, 2%-5% of plasticizer, and 2%-6% of chelating agent. The preparation method comprises the steps of firstly the polylactic acid and nylon 6 being desiccatingly treated for 2-3 hours; then the raw materials of nylon 6, chelating agent, and plasticizer being together mixed evenly in a high speed blender with a rotating speed of 800-1500 rotates / minute; then the well mixed mixture adopting a double screw rod extruder and melt blending to prepare granules, the granule preparation temperature being controlled between 200-250 DEG C; the obtained particle then being high speed blended with polylactic acid and the compatibilizer, the double screw rod extruder extruding out the prepared granules; then carrying out injection molding. The prepared film product solves the pollution problem to environment caused by the dissoluble plastic component nylon 6.

Description

Technical field [0001] The invention is to improve or solve the technical problem of the biodegradability of non-biodegradable polymer materials. It relates to a method for preparing a polylactic acid / nylon 6 blended gold biodegradable material by blending a biodegradable material polylactic acid and a non-biodegradable material nylon 6. Background technique [0002] The application range and dosage of polymer materials are increasing rapidly, but most of the polymer materials degrade very slowly in nature after being abandoned, which seriously pollutes the environment. In recent years, the white pollution caused by the difficulty of degrading waste plastics has become more and more serious. It has attracted widespread attention around the world, and some protection and restriction measures have been taken. For example, countries around the world have successively introduced restrictions or prohibits the use of non-degradable plastic packaging. Regulations. Therefore, the devel...
