Embodiment Construction

[0008] A flame-retardant waste plastic is composed of the following raw materials in weight percentage: 88% waste plastic, 7% flame retardant, 3% adhesive, and 2% lubricant. The waste plastic is polyethylene, polypropylene, polystyrene or polyvinyl chloride; the flame retardant is alumina trihydrate or zinc borate; the adhesive is epoxy resin adhesive; the lubricant is stearamide.

[0009] The pretreatment process of waste plastics: waste plastics, cleaning, drying, and testing. The cleaning system mainly includes: pre-washing part, cleaning part and rinsing part. Mainly the recycling technology in the cleaning system, the separation of impurities in the plastic and the control of plastic quality, and the optimization of process parameters. The cleaning system has high quality products after cleaning, short cleaning time, high efficiency and low energy consumption.

[0010] Modification and recycling of waste plastics is to add different modifiers according to the characteristics...

Abstract

The invention relates to flame retardant waste plastic, which is composed of the following raw materials, by weight, 88% of waste plastic, 7% of flame retardant, 3% of adhesive and 2% of lubricant. The waste plastic is polyethylene, polypropylene, polystyrene or polrvinyl chloride, the flame retardant is alumina trihydrate or zinc borate, the adhesive is epoxy resin adhesive, and the lubricant is stearamide. The flame retardant waste plastic is resource utilization of recycled waste plastic and is good in flame retardant effect.

Description

Technical field [0001] The present invention relates to plastics, in particular to a flame-retardant waste plastic. Background technique [0002] Waste plastic is a general term for plastics that have been used and eventually eliminated or replaced in civil, industrial and other purposes. According to different ways of reuse, it can be divided into: recycled plastic, reprocessed plastic, recycled plastic, reusable plastic, recyclable plastic, non-recyclable plastic. [0003] Recycled plastics: After pre-processing by factory molding, extrusion, etc., the leftovers or unqualified molded products are reprocessed in a secondary processing plant to prepare thermoplastics. In many specifications, recycled plastics are limited to clean plastics. They meet the requirements for new materials, and their product quality is actually equivalent to products made from new materials. Reprocessed plastics: Thermoplastics made from waste industrial plastics by non-original processors. Recycled p...
