Waste rubber/plastic regenerated product set and preparation method thereof

Abstract

The invention provides a waste rubber / plastic regenerated product set and a preparation method thereof. The set comprises a product subset A or / and a product subset B, wherein the product subset A isacquired by thermal cracking of waste rubber or / and waste plastics, and the product subset B is acquired by non-thermal cracking. The B comprises conversion energy for blending or / and using the A, theregenerated rubber / plastic product subset B is acquired by a combination method, or / and the B further comprises core / shell-shaped regenerated rubber or / and plastics, the A at least comprises A1 or / and A6 or / and A7 or / and A8 or / and A9, the A1 is waste rubber / waste plastic thermal cracking heavy oil capable of serving as a rubber / plastic softening agent or / and thickening agent, the A6 is a crushedor recycled particle capable of serving as a rubber / plastic fine grinding promoting agent or / and a reinforcing / filling auxiliary material, cracking residues are grinded, sieved by a 200-mesh screen and subjected to PAH (polycyclic aromatic hydrocarbons) removal treatment to obtain the particle, the A7 is cracking residue burning ash capable of replacing or partially replacing slaked lime and serving as a burning tail gas absorbent, and the dampening pH (potential of hydrogen) of the cracking residue burning ash is larger than 8.

Description

technical field [0001] The present invention proposes a collection of waste rubber / plastic regenerated products and its manufacturing method, which involves the innovation of waste rubber / waste plastic through thermal cracking process and its product approach; it belongs to the combination method of waste rubber / waste plastic resource recycling or Coupled with the technical scope of the business model. technical background [0002] Traditional and classic waste rubber recycling products mainly come from three mainstream processes, namely: thermal reclaimed rubber, freezing or normal temperature fine rubber powder, and thermal cracking method to extract oil; traditional and classic waste plastic recycling products are also It is mainly obtained through three mainstream processes, namely: thermal extrusion granulation, normal temperature crushing granulation, and thermal cracking method for oil extraction. [0003] But the product that obtains by above-mentioned traditional c...

[0010] But CN99114968.8 described "distillation range components below 120 DEG C are used as softening agent in rubber industry", through practical application, it is found that there is a serious odor defect: because when the rubber industry uses this softening agent to produce rubber products, when rubber products In the thermal vulcanization process, it will always be molded into the mold with a heating range of 140°C to 180°C, then this kind of softener, which is a distillation range component below 120°C, will overflow from the blended product, resulting in thermal vulcanization in rubber product companies. The workshop and the surrounding environment are filled with unpleasant odors

[0016] Although the above-mentioned new methods have opened up a new field of combined methods for waste rubber / plastic regeneration, these works are only analyzed from a technical level, and there are still many deficiencies: First, as a sub-path in the combined method—pyrolysis , the cleanliness and high-quality and high-value of the oil obtained are thermally regenerated and finely crushed at room temperature, which are also sub-paths in the combination method. The joints have not yet been opened; The pyrolysis slag that is not sold well in the market is usually incinerated as fuel to recover heat, but the large amount of white ash after burning is not used as a resource; third, waste rubber / plastic regeneration is a high energy-consuming recycling industry. However, the thermal cracking sub-process in the combined method is an energy-gaining approach, and at present this energy-gaining approach has not yet been unimpededly connected to the high energy-consuming sub-path in the combined method; There is no literature report on how polycyclic aromatic hydrocarbons contained in oil and pyrolysis slag products can adapt to the market demand of low content; fifth, the steric barrier effect of rubber powder, especially ultrafine rubber powder, at least in graphene, Carbon nanotubes have not been reported on the application of synergistic applications in the field of rubber products
