Embodiment

[0011] The above-mentioned modified elastic plastic powder material includes the following mass percentage components: 45% residual oil residue, 30% waste rubber particles, 12% resin, 5% recycled plastics, and 8% SBS copolymer in addition. The method is: heat the residual oil residue to 155°C, then evenly add waste rubber particles, stir for 45 minutes, then shear and evenly add resin and stir for 45 minutes; cool down to 120°C, add SBS copolymer, continue to stir and swell for 45 minutes, and then Dry and grind to produce elastic plastic powder. The raw materials of the present invention include residues left after refining biodiesel from waste oil and recycled plastics. The present invention not only reduces production costs, but also recycles renewable resources to meet the performance requirements of road construction and paving fields, and has good environmental and economic benefits; the present invention has simple process , the prepared residual oil-based modified biop...

Abstract

The invention provides a method for preparing modified flexible plastic powder from residual and waste oil bases, belonging to the technical field of waste reclamation. The modified elastic plastic powder comprises, by mass, 45% of residual oil residues, 30% of waste rubber particles, 12% of resin, 5% of recycled plastics and 8% of a SBS copolymer. The preparation method comprises the following steps: heating the residual oil residues to 155 DEG C; then uniformly adding the waste rubber particles and carrying out stirring for 45 min; carrying out uniform shearing, then adding the resin and carrying out for 45 min; carrying out cooling to 120 DEG C and adding the SBS copolymer; continuing stirring and swelling for 45 min; and carrying out drying and grinding so as to produce the flexible plastic powder.

Description

technical field [0001] The invention belongs to the technical field of waste regeneration, and in particular relates to a preparation method for making elastic plastic powder by using residual waste oil base. Background technique [0002] Plastic powder is widely used in sports plastic playgrounds, playgrounds, corridors, sidewalks, etc. It is generally processed from waste tires and additives. With the rapid development of my country's urban sports industry, the amount of plastic powder is increasing rapidly. In recent years, domestic plastic powder consumption occasions have become more diversified. Road plastic powder cement mainly comes from petroleum, and as a non-renewable resource, petroleum is facing a crisis of imbalance between supply and demand. In addition, there are some defects in the performance of traditional fields and roads, which need further research and improvement. Therefore, it is urgent to develop a new type of binder to partially or completely repl...
