A kind of mechanical parts protective wax and preparation method thereof

Abstract

The invention discloses a protective wax for mechanical parts and a preparation method thereof. The modified curing agent is prepared by the following process: first, aniline, formaldehyde and concentrated hydrochloric acid with a concentration of 25% are introduced into a stirring tank together, heated to 55 After reacting for 3 hours at high temperature, neutralize it with sodium carbonate solution, then introduce ammonia water into it, after step-by-step precipitation, filter and remove impurities, the mixed solution is exported to the absorption tower, and then dilute sulfuric acid with a concentration of 30% At the same time, phosphine gas is introduced into it. Under the pressure of 1.5MPa and temperature of 65 degrees, it is absorbed by the absorption tower for 2 hours, and after recrystallization and purification with deionized water, it is filtered and cooled to obtain modified Curing agent; in the present invention, the solvent is evenly preheated and blended with other raw materials, so that each system is in a constant temperature premixed state, and then blended in batches in sequence, and then more violent molecular-level movement occurs. In order to obtain a protective wax with better consistency on the microscopic surface.

Description

technical field [0001] The invention relates to the technical field of protective wax, in particular to a protective wax for mechanical parts and a preparation method thereof. Background technique [0002] Protective wax is a kind of traditional paint maintenance material, which can penetrate into the gap or adhere to the surface to increase the brightness and protect the product. Waxes on the market can be divided into three categories: liquid wax, paste wax and hard wax, and most of them are used for smearing and coating of mechanical parts, vehicles, metal objects and furniture. [0003] However, in the existing protective wax for mechanical parts, there are problems of poor heat resistance and poor curing effect. When the ambient temperature during use is too high, it is easy to cause the viscosity of the protective wax to decrease, and then dissolve and fall off. The service life and scope of the product have been seriously affected; and in the preparation process of t...

Problems solved by technology

[0007] Firstly, the third rotating shaft drives the cam to rotate, and the cam cooperates with the cam groove at the bottom of the blending tank to drive the blending tank to move up and down, and then drives the first rotating shaft and the blending blade at one end to rotate according to the first bevel gear , that is, the up-and-down movement of the blending tank is coordinated with the rotation of the blending blades to solve the problems of poor uniformity and obvious stratification during blending, so that all raw materials in the blending tank can be fully mixed. From a microscopic point of view, the molecules of each raw material can be completely dispersed without agglomeration, which greatly improves the quality of the produced product, and in the whole working process, the up and down movement of the blending tank will make the first slide The block, the connecting rod and the second slider move together, and are elastically deformed according to the first memory spring, the second memory spring and the buffer air bag, and then the blending tank can be fully supported by the common restoring force of the three , and greatly reduce the shaking of the blending tank itself or the influence of external forces when it is working, effectively improving the stability of the work
