Abstract
The invention discloses a method for recovering polystyrene waste plastic. The method comprises the following steps of: (1) sorting and cleaning collected polystyrene sheet waste; (2) drying the cleaned waste at the temperature of 110-120 DEG C; (3) smashing the dried waste; and (4) modifying the smashed waste, wherein a modifier used for modifying the waste in the step (4) consists of the following components in percentage by weight: 2-3 percent of a toughening agent, 1-2 percent of a plasticizing agent and 1-3 percent of a color masterbatch; the weight percentage is determined on the basis of the weight of the modified polystyrene sheet waste; and the toughening agent is a thermoplastic elastomer. According to the recovery method, polystyrene waste plastic can be recovered conveniently; and polystyrene waste plastic can be recycled by modifying, so that production cost can be reduced, and the problem of environmental pollution is solved.
Description
Technical field
The present invention relates to the plastics recovery field, particularly relate to a kind of recovery method of PS waste or used plastics.
Background technology
Advantage obtains using widely rapidly the disposable plastic goods because of its light weight, price be low, easy to use etc.But, well-known, in the convenient use of plastics, also caused unprecedented " white pollution " disaster.Being processed into the disposable product that has only several minutes use value to non-renewable petroleum resources is the significant wastage to Nonrenewable resources.And the present method that does not still have proper recycled disposable plastic goods waste material such as PS waste or used plastics.
Summary of the invention
The recovery method that the purpose of this invention is to provide a kind of PS waste or used plastics.
For this reason, technical scheme of the present invention is following:
A kind of recovery method of PS waste or used plastics may further comprise the steps:
1) collected PS sheet material waste material is chosen and cleaned;
2) under 110～120 ℃ the waste material after cleaning is being dried processing;
3) waste material after will drying is pulverized;
4) waste material after pulverizing is carried out modification.
Wherein, the properties-correcting agent that in the step 4) waste material is carried out modification is made up of components in weight percentage down:
Toughner 2～3%
Fluidizer 1～2%
Colour batch 1～3%.
Above-mentioned weight percent is a benchmark with the weight of the PS sheet material waste material that is modified.
Said toughner is thermoplastic elastomer, and preferably, said thermoplastic elastomer is styrene block copolymer (SBC) or thermoplastic sulfurized rubber (TPV).
The recovery method of PS waste or used plastics of the present invention; P-poly-phenyl ethene waste or used plastics recycles easily, carries out modification through p-poly-phenyl ethene waste or used plastics, and it can be utilized once more; Not only can reduce production costs, also solve environmental issue.
