Abstract

The invention discloses a production device for degradable polypropylene plastics and a preparation method of the degradable polypropylene plastics. The production device is characterized by comprising a bottom plate; a mixing box is fixedly installed on the upper surface of the bottom plate; a mixing mechanism is arranged in the mixing box; the mixing mechanism is installed on the surface of the mixing box through a bearing; a material conveying mechanism is arranged on one side of the mixing box; and the material conveying mechanism is fixedly installed on the upper surface of the bottom plate. A first discharging pipe is fixedly installed on the lower side of the mixing box; the first discharging pipe is connected with the material conveying mechanism; an installation rack is arranged on one side of the material conveying mechanism; and a reactor is fixedly installed on the installation rack. By arranging the mixing box, the degradable polypropylene raw material is easy to place; due to the mixing mechanism, all the raw materials are sufficiently mixed, and the improvement on the quality of the degradable polypropylene plastics is facilitated; and by arranging the material conveying mechanism, the raw materials mixed by the mixing mechanism are easily drawn into the reactor for heating and melting.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a production equipment for degradable polypropylene plastic and a preparation method thereof. Background technique [0002] Disposable plastic products are widely used in people's daily life due to the advantages of light weight, low price, and convenient use. The main components of ordinary disposable plastic products are organic polymer materials such as polyethylene, which are difficult to decompose in the natural environment, resulting in serious "white pollution" problems. With the advancement of science and the improvement of people's awareness of environmental protection, the research and development of biodegradable plastics have received more and more attention. [0003] For example, the Chinese patent whose authorized notification number is CN 108518937 A discloses a plastic granule processing equipment for engineering plastics production, including a base p...
