preparation example Construction

[0042] The second aspect of the present invention provides a method for preparing a surface conditioner. The specific preparation steps of the surface conditioner include: weighing raw materials according to the formula amount, adding the raw materials into a reaction kettle and mixing them uniformly, standing still, and packaging to obtain the finished product.

[0043] In some preferred embodiments, the standing time is 5-8 days.

[0044] In some preferred embodiments, the surface conditioner is suitable for surface treatment of zinc-based phosphating agents, manganese-based phosphating agents, and calcium-based phosphating agents; further preferably, the surface conditioner is especially suitable for manganese-based phosphating agents. The surface treatment of the workpiece before the use of phosphating agent.

Abstract

The invention relates to the technical field of surface treatment, in particular to a surface conditioning agent and a preparation method thereof. The raw materials comprise 5%-10% of manganese salt, 0.07%-0.15% of a blackening aid, 6%-10% of sodium salt, 0.1%-1% of an accelerant and the balance water. The surface conditioning agent prepared by the invention has the following advantages that (1) a workpiece treated by the surface conditioning agent can obtain a more uniform and compact film layer after phosphorization, and the corrosion resistance of the workpiece is improved; (2) the obtained surface conditioning agent can improve the workpiece surface treatment efficiency and shorten the phosphating time; (3) the obtained surface conditioning agent can improve the appearance attractiveness of the workpiece, so that a phosphating film is glittering, translucent, smoother, black and brighter; and (4) the obtained surface conditioning agent is high in adaptability, can achieve a synergistic effect with various phosphating agents, has an excellent enhancement effect, is easy in raw material obtaining and simple and convenient in process, has the advantages of economy and environmental protection, and is wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a surface conditioner and a preparation method thereof. Background technique [0002] "Surface adjustment" is referred to as surface adjustment, which is a means to improve the physical and chemical properties of the material surface through physical and chemical methods, so as to achieve the best specific function of the material surface in various occasions. It is often used on the surface of metals before phosphating deal with. The quality, crystal shape and size of the phosphating film depend to a large extent on the cleaning and treatment of the metal surface, which can be divided into 3 categories: (1) mechanical action treatment, such as wiping, brushing, wiping, grinding, Sandblasting, shot blasting, and wiping steel with cloth or steel balls can improve the quality of the phosphating film, and the crystallization will be finer and more uniform. However, this m...
