Problems solved by technology

[0002] In daily life and scientific research and production, a large amount of waste plastics are produced every day. Since plastics are polymer materials, they are not easy to degrade, and they are directly buried, which not only wastes precious resources, but also has a great impact on the soil. Burning treatment will also cause Harmful and other polluting environment has been banned; therefore, how to deal with waste plastics in an environmentally friendly manner has become a very critical issue

Embodiment Construction

[0020] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] A method for recycling plastics is characterized in that it mainly comprises the steps of:

[0022] Step 1: Precipitate, rinse with water in the pool, and after standing, remove impurities such as soil;

[0023] Step 2: Washing, cleaning the plastic with a degreasing solvent to remove oil and other organic matter, then rinsing with clean water and then drying;

[0024] Step 3: Crushing, pulverizing the degreased plastic;

[0025] Step 4: Dissolving, fully contacting the dissolving solvent capable of dissolving the plastic with the pulverized plastic, and in the presence of a phase separation agent, using a non-solvent to precipitate the plastic dissolved in the decomposition solvent, wherein the phase separation agent and the decomposition Compatible with solvents and incompatible with...

Abstract

The invention discloses a plastic recovery method. The plastic recovery method is characterized by mainly comprising the steps of: (1) precipitation: water is used for flushing in a pool; and such impurities as soil are removed after standing; (2) washing: oil removing solvent is used for cleaning plastic; (3) crushing: the plastic is crushed after oil stains are removed; (4) dissolving; and (5) recovery: plastic particles in the step (4) are recovered. The plastic recovery method has the following advantages: through multistage treatment, such impurities as soil can be removed through precipitation; the oil removing solvent is used for washing to remove such organic matters as the oil stains; the drying is performed after cleaning to conveniently perform the crushing work; after the plastic is crushed, the total surface area can be greatly increased; and finally, the plastic particles are dissolved through the dissolving agent for such operations as re-separation to obtain finer particles capable of reusing.

Description

technical field [0001] The invention relates to a plastic recycling method. Background technique [0002] In daily life and scientific research and production, a large amount of waste plastics are produced every day. Since plastics are polymer materials, they are not easy to degrade, and they are directly buried, which not only wastes precious resources, but also has a great impact on the soil. Burning treatment will also cause It has been prohibited to generate harmful and other environmental pollution; therefore, how to deal with waste plastics in an environmentally friendly manner has become a very critical issue. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a method for recycling plastics, which can process waste plastics more environmentally friendly. [0004] In order to solve the above-mentioned technical problems, the present invention provides a method for re...
