Example Embodiment

[0018] In Example 1, the present invention modified waste plastics by developing a compatible and coupled modifier, and then used a process method to produce construction products. The principle is: the plastics contained in garbage plastics are basically thermoplastics such as PE, PP, ABS, EVA, and a very small amount of PVC, PET, etc.; through the use of acrylic ester copolymers, maleic anhydride Polyolefin resins, ethylene acrylic acid copolymers are grafted with polar monomers, maleic anhydride and other grafted plant fibers as polymer-compatible modifiers. The modifiers can be acrylate copolymers, Maleic anhydride-modified polyolefin resin, ethylene acrylic acid copolymer grafted with polar monomers on the molecular chain, or maleic anhydride and other grafted plant fibers, or two or two of them Any combination of the above materials. When the modifier is added, the weight ratio of garbage plastic pellets to modifier is 100: (1-2). By adding the above modifiers, the main...

Example Embodiment

[0019] In Example 2, the recycled garbage plastics are directly pelletized, and then the modifiers and fillers with compatibility and coupling properties are added and then the alloy is modified. When the modifiers are added, the garbage plastic pellets and modified The weight ratio of the agent is 100: (1-2), the filler can be any one of rice husk, bran powder, or wood flour, or any two or more of them can be combined in any way, modified The weight ratio of the plastic pellets to the filler is 100: (25-35). Since the main component of the filler is cellulose, the present invention uses organic fibers such as rice husk, bran powder, wood flour, etc. as fillers to physically modify waste plastics. The raw materials are green and environmentally friendly, so as to produce a new green and environmentally friendly plastic. Wood material. It is then made of plastic pellets to produce buried drainage combined pipelines for municipal construction, combined core molds or mold shells ...

Abstract

The invention relates to a recycling method of garbage plastic, and mainly solves the technical problems of high cost and large environmental pollution existing in the traditional technology methods. The technical schemes comprises the following steps: firstly directly granulating the recycled garbage plastic, then adding a modifier with compatibility and coupling performance and filler and mixing, then carrying out alloy modification, and then processing into plastic pellets to produce buried drainage combined pipelines for municipal building, combined core molds or mold shells for building structures, or wall heat-insulation inner molds. Through the recycling method provided by the invention, garbage plastic can be recycled, and the process method is relatively simple and generates little environmental pollution. The treated recycled plastic including garbage plastic can be used to manufacture in-situ cast reinforced concrete core molds or manufacture industrial and building articles, daily necessities and the like, and can also be used to manufacture production raw materials such as granulation materials.

Description

technical field [0001] The invention relates to a process for recycling waste plastics, in particular to a process for recycling, processing and reusing waste plastics. Background technique [0002] It is relatively easy to recycle and dispose of relatively large waste plastics that have a good overall recovery from the society, and the utilization rate is also the highest; There are many impurities, the treatment process is complicated, and the cost is high. Therefore, the scattered plastic daily necessities contained in domestic waste are basically not recycled. They are generally disposed of by landfill or incineration, which not only causes waste of resources, but also easily pollute the environment. Even if the scattered plastic daily necessities contained in domestic garbage are sorted out for reuse, the existing recycling method usually adopts the method of water separation and sorting, which consumes a lot of water. This process has high cost and great environmental...
