Modification of waste plastics to produce special materials for hollow floor filling bodies and its preparation method

Abstract

The invention relates to a special material for hollow floor fillers produced by modification of waste plastics and a preparation method thereof, which relates to the field of polymer molding processing, and is to sort out usable waste plastics from recyclables, crush the sorted materials; put the crushed materials into Add water to the cleaning equipment for cleaning; put the washed materials into the dryer for drying treatment; take the dried materials and various additives according to 100 parts of waste plastics, 40 parts of modified wood powder, EAA6-8 1 part, 0.5-1 part of dispersant, 3-5 parts of black masterbatch; put the mixed material into the extruder for extrusion granulation, and put the extruded strips into the pelletizer Cut into granules by machine; pack the granulated granules into bags. The beneficial effect is to provide a method for processing waste plastics. It can not only change the situation that landfill and simple incineration are the main treatment methods for waste plastics in my country, but also contribute to the control of environmental pollution and create huge economic benefits.

Description

Technical field: [0001] The invention relates to the field of polymer molding and processing, in particular to the modification and granulation of waste plastics, in particular to a special material for producing hollow floor fillers by modification of waste plastics and a preparation method thereof. Background technique: [0002] my country is a country with relatively scarce resources per capita. The per capita possession of the main 45 kinds of resources is less than half of the world average. Waste plastic resources are called "urban treasures" by modern economists. As we all know, plastic raw materials are chemical products extracted from natural petroleum. Petroleum is the lifeblood of modern industry and is related to the energy of the country. According to the statistics of relevant departments, the plastic waste produced by a medium-sized city every year can meet the needs of 20 small and medium-sized plastic enterprises. Raw material demand, therefore, recycled pla...

Problems solved by technology

At present, my country's plastic waste treatment methods are mainly landfill and simple incineration. Landfill needs to occupy a lot of valuable land, and it will pollute the surrounding environment and groundwater resources. Simple incineration will also emit harmful gases and residues. Bad strategy
