Preparation method of environment-friendly chemical mixed additive

Abstract

The invention discloses a preparation method of an environment-friendly chemical mixed additive. The preparation method is characterized by comprising the following steps: (1) finely crushing additive powder and controlling the particle diameter of the finely-crushed additive powder to be 2000-5000 meshes; (2) adding the finely-crushed additive powder and a right amount of stearic acid powder into a high-speed stirrer, and controlling the rotation rate of the stirrer to be 1000 r / min or higher until all the powder is fully mixed to be a viscous material; (3) cooling and solidifying the viscous material to obtain a solid material; (4) putting the solid material into a pelletizer for pelletizing, so as to obtain mixed additive particles after the pelletizing; (5) putting the mixed additive particles on a sieve for sieving until qualified products with particle diameters of 2-6 mm are obtained. The prepared mixed additive is a particle mixture, innovative in mixing of the additive powder and pelletizing, and has the most important characteristic of being environment-friendly; meanwhile, the mixed additive is convenient in application, less in waste, lower in cost, smaller in space, and accurate in material adoption; through the adoption of the mixed additive, the physical properties and the quality of plastic rubber products can be more stable and higher respectively.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly chemical mixing auxiliary agent. Background technique [0002] In the plastic chemical industry, it is necessary to use a large amount of chemical additives. There are many types of chemical additives. One chemical additive is usually used for one purpose, but often different plastic and rubber products need to add a variety of chemical additives. Various chemical additives Chemical additives need to be mixed and used, and most of the common properties of chemical additives are powder materials, which brings many problems, the most important of which is environmental protection. In the process of using chemical additives, one or more different additive powders need to be added to the internal mixer according to the required weight and mixed with large materials (referring to rubber raw materials) for mixing.

Problems solved by technology

In the process of using chemical additives, one or more different additive powders need to be added to the internal mixer according to the required weight and mixed with large materials (referring to rubber raw materials) for mixing. The application is inconvenient, and the labor intensity of the workers is high. A large amount of dust will be generated during this process. It is estimated that the auxiliary powder material that becomes dust and escapes can account for more than 20% of the total amount of additives, which makes the materials used for additives inaccurate. The amount of additives often has a great impact on the quality of plastic and rubber products. Although most of the dust will be sucked away by the vacuum equipment equipped in the workshop and cause waste, a small part will seriously pollute the environment, and it is difficult to meet environmental protection standards. , even if workers wear masks to produce, their health will be seriously affected

Not only that, powder additives will generate dust during transportation, loading and unloading, etc., which will affect the environment. In addition, various additives with various names are stacked together, which takes up a lot of space and piles up costs; It is difficult for the material to mix evenly with the aniseed material in the aniseed material, and the dispersion is not good, so it is easy to make the physical properties of the produced plastic and rubber products unstable and the quality is not good
