Preparation process of plastic processing lubricant

Abstract

The invention relates to the technical field of plastic processing lubricants, in particular to a preparation process of a plastic processing lubricant. A reaction kettle used in the process comprises a tank body, a discharge port is formed in one side of a bottom plate of the tank body, a feed port is formed in one side of an upper cover of the tank body, a motor is fixedly arranged in the middle of the upper cover, the output end of the motor is rotationally connected with a rotating shaft, the rotating shaft extends into the tank body and is connected with a plurality of stirring blades, a plurality of heating assemblies are uniformly distributed in the side wall of the tank body, a grinding block is fixedly arranged on the rotating shaft at the upper part in the tank body, the upper end of the grinding block is arranged as a conical surface, and a gap is formed between the periphery of the grinding block and the inner wall of the tank body. According to the preparation process of a plastic processing lubricant, through the arrangement of the grinding block, the heating surface area of materials is increased, the feeding and melting speed of the materials is increased, the preparation time is shortened, and the working efficiency is improved; and meanwhile, the materials can be ground and refined, so that the materials are more easily and uniformly stirred, and a better lubricating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic processing lubricants, in particular to a preparation process of plastic processing lubricants. Background technique [0002] my country's plastic production and processing volume ranks second in the world, and its annual demand accounts for 10 percent of the world's total consumption. The actual situation in China is: there are many general-purpose plastics produced, resulting in a surplus of products, while the production of engineering plastics is small, and a large number of imports are required to fill the gap every year. Taking polypropylene as an example, it imported 162 tons in 2000 and 5.2 million tons in 2009. [0003] Strengthening the modification of plastics and increasing the production capacity of engineering plastics is one of the major research projects in the petrochemical industry during the 11th Five-Year Plan. At present, there are two common methods: one is to use polymer sy...

Problems solved by technology

[0007] In order to make up for the deficiencies of the prior art and solve the problem that the stirring effect of the existing reactor is not good, which leads to the poor fluidity of the internal materials, it is difficult to ensure that the materials are evenly stirred, and therefore it is difficult to ensure the quality of the prepared lubricant. The present invention proposes A kind of preparation technology of plastic processing lubricant
