Embodiment Construction

[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the invention discloses a method for making environmentally friendly plastics, and the specific operation steps are as follows:

[0019] (1) Step S101: mixing, adding citric acid ester, glyceryl triacetate and antioxidants to cellulose diacetate, and then mixing to obtain a mixture, the mass ratio of the four substances in the mixture is <70% in turn: < 20%:<35%:<1%, then execute step S102;

[0020] (2) Step S102: heating, heating the mixture at a temperature range of 60°C to 120°C for 3 to 6 hours to fully melt and mix, and proceed to step S103 after mixing evenly;

[0021] (3) Step S103: Extrusion molding. On a twin-screw extruder, the heated mixture is extruded, then cooled, and finally shaped to form plastic sheets or pellets.

[0022] Wherein, the mass ratio of the cellulose diacetate is pr...

Abstract

The invention discloses an environment-friendly plastic making method, which includes the steps of: mixing cellulose diacetate, citrate, glyceryl triacetate and an antioxidant according to a mass ratio to obtain a mixture; then heating the mixture; and subjecting the heated mixture to plasticizing molding on an extruder. The method provided by the invention adopts the mixture of citrate and glyceryl triacetate to replace the original plasticizer, so that the plastic product produced by the invention is easy to degrade, thus reducing environmental pollution and realizing the environment-friendly plastic making method. The plastic making method provided by the invention reasonably sets the mass ratio of cellulose diacetate, citrate and glyceryl triacetate, ensures certain toughness of the plastic, and also successfully achieves plasticizing molding. A low heating temperature and reasonable time adjustment make the processed plastic product have more uniform color and higher strength. With higher stability, the plastic can be more durable.

Description

technical field [0001] The invention relates to the technical field of plastic manufacturing methods, in particular to an environmentally friendly plastic manufacturing method. Background technique [0002] The main component of existing plastic sheets or granules is cellulose diacetate, the use of cellulose diacetate can enhance the flexibility of plastic products, and compared with other materials, cellulose diacetate is easier to process, so the more More and more producers use cellulose diacetate as the main raw material for plastics. [0003] However, in the production process of plastics, it is often necessary to add phthalates and other substances as plasticizers. Such plasticizers are harmful to the human body, and plasticizers are difficult to be recycled and difficult to degrade. It is very large, which seriously pollutes the environment and affects the production and application of plastics to a large extent, which does not conform to the current concept of envir...
