Problems solved by technology

In order to overcome the above problems, it is necessary to solve the compatibility problem between garbage plastics and between garbage plastics and fillers first, so it is necessary to develop a new type of multifunctional composite modifier, which must have a compatibilizer and a coupling agent. In order to improve the compatibility between waste plastics and between waste plastics and fillers, a new production process can be designed

Embodiment 1

[0018] Embodiment 1, the present invention modifies garbage plastics by developing a modifier with compatibility and coupling, and then produces construction products. The principle is: the types of plastics contained in garbage plastics are basically thermoplastics such as PE, PP, ABS, EVA, etc., and there are also very small amounts of PVC, PET, etc.; Grafting plant fibers such as polar monomers and maleic anhydride on the molecular chains of permanent polyolefin resins, ethylene acrylic acid copolymers are used as polymer compatible modifiers, and the modifiers can be acrylate copolymers, Any one of maleic anhydride-modified polyolefin resin, ethylene acrylic acid copolymer grafted with polar monomers, or grafted plant fibers such as maleic anhydride, or two or two of them Any combination of the above substances. When the modifier is added, the weight ratio of the garbage plastic pellets to the modifier is 100: (1-2). By adding the above-mentioned modifiers, the main chai...

Embodiment 2

[0019] Example 2, first directly granulate recycled garbage plastics, then add modifiers with compatibility and coupling properties and fillers to mix and carry out alloy modification. When modifiers are added, garbage plastic pellets and modified The weight ratio of the agent is 100: (1-2), and the filler can be any one of rice husk, bran powder, or wood powder, or any combination of any two or more of them, modified The weight ratio of the final plastic pellets to the filler is 100: (25-35). Because the main component of the filler is cellulose, the present invention uses organic fibers such as rice husk, bran powder, and wood powder as fillers to physically modify waste plastics, and adopts green and environmentally friendly raw materials to produce a brand new green and environmentally friendly plastic. wood material. It is then made into plastic pellets to produce buried drainage composite pipes for municipal construction, composite core molds or mold shells for building...

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...
