Problems solved by technology

However, if the piston is made of aluminum, and the cylinder body is also made of aluminum, and the form of no cylinder liner is adopted, no effective friction pair can be formed between the piston skirt and the cylinder liner, which will further reduce the life of the engine and bring a great deal to the safety of the car. Hidden danger
Due to the high density of iron in the printing liquid of iron printing, the iron printing liquid is uneven and easy to precipitate; compared with graphite printing, the adhesion between the iron printing coating and the substrate is more difficult to control; the appearance of the iron printing coating is easy to cause unevenness

Embodiment 1

[0030] The invention relates to a printing solution for iron printing coating on the surface treatment of piston skirt, and its raw materials include high temperature resistant resin, stainless steel powder, diluent, curing agent and curing accelerator. Prepare about 5kg of printing liquid, and its specific raw materials and dosage are as follows:

[0031]

[0032] Among them, 100% stainless steel powder particle size < 63 μm, 99.5% stainless steel powder particle size < 40 μm, the same below. According to the printing solution of the iron printing coating used for the surface treatment of the piston skirt of the present invention, the content of the stainless steel powder can be 10% to 15%.

[0033] Compared with printed graphite, due to the high density of iron (stainless steel powder) in the printed iron coating, it is easy to precipitate, and its bonding force with the aluminum substrate is not good. In order to overcome this difficulty, in the formula of the present in...

Abstract

The invention relates to a printing solution of an iron printing coating. The printing solution is prepared from raw materials as follows: high-temperature resistant resin, stainless steel powder, a diluent, curing agents and curing accelerators, wherein the high temperature resistant resin is epoxy resin E-44, the diluent is N-methyl pyrrolidone, the curing agents comprise dicyandiamide and dimethylformamide, and the curing accelerators comprise triethylenetetramine and tetraethylenepentamine. The iron printing coating is prepared from the printing solution by screen printing, environmental pollution is avoided, fewer materials are wasted, thickness of the iron printing coating is uniform, and adhesion is firm. The printing solution is completely suitable for aluminum pistons and cylinders to form an effective friction pair, and thus, the service life of an engine is prolonged while weight of the engine is reduced.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of aluminum pistons, and relates to a printing solution for iron-printed coating and a method for preparing the iron-printed coating. Background technique [0002] For a car, the engine is like the "heart" of the car, and the piston is the "center" of the engine, which directly affects the reliability and durability of the engine. The piston skirt is an important part of the piston. The working condition of the piston skirt-cylinder liner friction pair directly affects its function guarantee. The piston skirt-cylinder liner system is one of the most important friction pairs in automobile engines with the most demanding working conditions. First, it is also the friction pair with the largest friction loss in the engine. Moreover, the piston is in a harsh working environment. The piston is directly in contact with high-temperature gas, and the instantaneous temperature can reach above 250...
