In recent years, the high-tech product "metal parts repair agent" developed by our country has been widely used in products such as construction machinery. The repair agent is mainly used for parts repair in mechanical products, such as castings, machined parts, etc. In the manufacturing process, there will be defects and processing errors that cause the scrapping of parts. At the same time, the wear of parts will also cause the failure of parts. Repairing with a repair agent can make the parts work normally. Therefore, the repair agent has great economic and social benefits. In order to make the repair agent more standardized, this standard is specially formulated. Some of the test methods in this standard implement the national standard.

Determination of tensile strength of butt joints of adhesivesDetermination method for tensile shear strength of adhesives (metal to metal)General technical rules for epoxy coating materials for sliding guidesUse solvent-based metal cleaner to remove surface oil stains and increase the bonding strength between the repair agent and the substrate. 3.1.2 Roughening and grinding
Use tools (angle grinder, emery cloth, file or sandblasting gun, etc.) to remove loose objects, rust and surface contaminants on the surface, or use acidic rust remover to remove rust, then rinse with clean water and dry. 3.1.3 Re-cleaning
Use solvent-based metal cleaner to clean the roughened surface again to ensure the surface is clean. 3.2 Preparation
3.2.1 Weighing
3.2.1.1 Weighing tool: balance with an accuracy of 0.1g. 3.2.1.2 Use their respective material removal tools to weigh components A and B according to the required ratio of the metal parts repair agent. 3.2.1.3 If weighing is inconvenient, use a measuring cup to visually estimate the volume ratio for preparation. Approved by China Machinery Industry Federation on June 22, 2001, implemented on October 1, 2001
3.2.2 Mixing
JB/T10283—2001
The repair agent consists of two components, A and B, which should be mixed evenly. The correct mixing method is to mix the two components together with a modulation tool, and stir and press in one direction until the color is consistent. The stirring speed should not be too fast to avoid mixing in bubbles. 3.3 Coating
3.3.1 Processing and molding method: Apply the mixed repair agent to the surface to be repaired after surface treatment. The first layer should be thin and pressed repeatedly with force to ensure that the repair agent is fully infiltrated with the metal surface, and then apply thicker layer by layer, leaving a margin for processing. 3.3.2 Mold molding method: The repair layer is not processed but molded with a high-precision mold, such as a model coated with a release agent after grinding, which can form a high-precision coating surface. First, apply or spray the release agent on the mold surface to form a uniform film; apply the mixed repair agent to the surface to be repaired and the inner surface of the mold according to method 3.3.1, and finally close the mold for positioning and pressing. 3.4 Curing
3.4.1 Ordinary metal parts repair agent
a) Cure the repaired part at a temperature of 15-40℃ and a relative humidity of less than 80% for 24 hours. b) If the temperature is lower than 15℃, appropriate heating measures should be taken to achieve complete curing. c) After curing at room temperature, heat to 80~100℃ and keep warm for 3 hours, which can improve the comprehensive performance of the repair layer by 10%~30%. 3.4.2 Fast-curing metal parts repair agent
a) Cure the repaired part at a temperature of 15~40℃ and a relative humidity of less than 80% for 12 hours. b) After curing at room temperature, heat to 80~100℃ and keep warm for 2h, which can improve the comprehensive performance of the repair layer by 10%~30%. 3.5 Machining
3.5.1 After curing, the parts can be machined (turning, grinding, drilling, tapping, etc.) to achieve the required dimensional accuracy. 3.5.2 If there are exposed pores on the surface after machining, repeat 3.1~3.5. 4 Basic performance requirements
