Recycling treatment method of waste plastic particles

Abstract

The invention discloses a waste plastic particle recycling treatment method, which comprises the following steps: waste plastic particles can be prepared into waste plastic powder, and then the wasteplastic powder is matched with wood fiber powder, clay, a plasticizer, a stabilizer, PE wax, stearic acid, a foaming regulator, a foaming agent and a dispersing agent to prepare a wood-plastic raw material; waste plastic resources can be fully utilized, and the prepared wood-plastic material is excellent in performance; according to the recycling treatment method, recycling processing equipment isused for processing the waste plastic particles; the waste plastic particles are crushed into powder; the waste plastic powder is conveyed into a first mixing tank and uniformly mixed with a plasticizer and a stabilizer; a first mixture is prepared, and then the first mixture is transported to a second mixing tank and mixed with other raw materials to obtain wood-plastic raw materials. Accordingto the present invention, the equipment has the high automation degree, the production efficiency of the wood-plastic material is effectively improved, and the problem that the waste plastic pollutesthe environment is well solved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a method for reusing waste plastic particles. Background technique [0002] With the wide application of plastics, the disposal of waste plastics has attracted increasing attention. Generally, there are three main ways to deal with waste plastics: landfill, incineration, and recycling. The recycling of waste plastics can not only reduce environmental pollution, but also save resources. It is the first choice for dealing with waste plastics. [0003] Combining plant fibers with recycled waste plastics to form wood-plastic composites can not only effectively solve some performance defects of a single material, but also the wide application of these wood-plastic composites in the fields of construction and engineering is crucial to solving the recycling of waste plastics. Utilization, long-term utilization is also a very effective way, and it is also an effective way to solve environmental ...

Problems solved by technology

[0006] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a recycling treatment method of waste plastic particles: by preparing wood-plastic materials from waste plastic particles, the wood-plastic materials include the following components: waste plastic powder, wood fiber Powder, clay, plasticizer, stabilizer, PE wax, stearic acid, foaming regulator, foaming agent, dispersant, by putting waste plastic particles into a drying box for heating and drying to obtain dry plastic particles , crush the dry plastic particles into powder, pass through a 100-mesh sieve to obtain waste plastic powder, add plasticizer and stabilizer to the waste plastic powder, heat and mix uniformly to obtain the first mixture, and process the wood fiber powder with alkali treatment to obtain alkali-treated lignocellulosic powder, acid-treating the clay to obtain acid-treated clay, uniformly mixing the alkali-treated lignocellulosic powder and acid-treated clay, and then drying until the moisture content is 2-3%, obtaining The second mixture, add stearic acid, PE wax, dispersant to the second mixture, heat and mix uniformly to prepare the third mixture, after mixing the first mixture and the third mixture uniformly, add foam regulator and foaming Fully stir the agent, cool it, and make wood-plastic raw materials, which solves the problems of poor mixing uniformity and interface compatibility of the existing wood-plastic composite system, and poor physical and chemical properties of the material.
