Problems solved by technology

The previous cleaning method is not ideal, and requires a lot of manpower and material resources, which greatly increases the cost
At present, the commonly used screw cleaning agents on the market have certain limitations in terms of cleaning efficiency, environmental protection, and cost. For example, environmentally friendly cleaning agents are difficult to clean the dead corners and gaps of the screw barrel, and the efficiency is low; while organic solvents Although screw cleaning agent can greatly improve the cleaning efficiency, there is another environmental pollution problem in the treatment of its products
At this stage, there are almost no effective and environmentally friendly screw cleaning agents in China, and the solid screw cleaning agents used are mainly imported.

Abstract

The invention discloses a double-screw high-efficiency environment-friendly pelletized particle cleaning agent and a production method thereof, and belongs to the technical field of high-molecular materials. The double-screw high-efficiency environment-friendly pelletized particle cleaning agent comprises matrix resin, inorganic powder, a lubricating agent and a coupling agent. The production method comprises the following steps of: (1) weighing the matrix resin, the inorganic powder, the lubricating agent and the coupling agent according to the proportioning part by weight; (2) drying the inorganic powder, adding the dried inorganic powder and the coupling agent into a highly-mixing machine, fully mixing and obtaining modified powder; (3) adding the modified powder in the step (2), the matrix resin and the lubricating agent in the high-speed mixing machine, adding the mixed materials into a hopper of an extruder, fusing, blending and extruding the mixed materials from the extruder, and carrying out bracing and granulation. The double-screw high-efficiency environment-friendly pelletized particle cleaning agent disclosed by the invention is convenient to take, low in price and convenient to clean and belongs to a nontoxic and pollution-free material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a twin-screw high-efficiency and environment-friendly granulation cleaning agent and a production method thereof. Background technique [0002] Plastic products have good performance, many varieties, easy processing and modification, and have become one of the indispensable materials in modern society. In the process of processing, there are more or less residues of plastic materials, especially for engineering plastic modification manufacturers, there has always been such troubles. According to the traditional cleaning method, the twin-screw screw needs to be disassembled when changing materials and colors. Down, clean with solvent or specific tools, and then install the belt after cleaning. In this way, it will take at least 1-2 days, which will not only cause waste of raw materials and environmental pollution, but also cause damage to the equipment screw ...
