Problems solved by technology

The traditional stainless steel and plastic bonding technology is to use adhesives to bond stainless steel and plastic together at room temperature or in a heated environment. The combination obtained in this way has poor bonding strength, limited applications, and cannot meet the actual use strength requirements of the product. The stainless steel treated by this method has a low bonding strength with the attached plastic on the surface, poor firmness, and low pull-out force

Abstract

A stainless steel surface nanoscale treatment technology comprises following steps: S1, stainless steel is put into a first surface treatment agent, and is soaked for 4 minutes to 6 minutes at the temperature of 50 DEG C to 60 DEG C; S2, the stainless steel obtained in the S1 is washed three times at the normal temperature; S3, the stainless steel obtained in the S2 is put into a second surface treatment agent, and is soaked for 2 minutes to 3 minutes at the normal temperature; S4, the stainless steel obtained in the S3 is washed three times at the normal temperature; S5, the stainless steel obtained in the S4 is put into a third surface treatment agent and is soaked for 1 minute to 2 minutes at the temperature of 40 DEG C; S6, the stainless steel obtained in the S5 is washed three times at the normal temperature; S7, the stainless steel obtained in the S6 is put into an ultrasonic cleaning machine containing pure water to be cleaned and is cleaned for 3 minutes at the normal temperature; S8, the stainless steel obtained in the S7 is put into a drying machine to be dried, the drying temperature ranges from 110 DEG C to 120 DEG C, the drying time ranges from 9 minutes to 12 minutes, and after drying, the steel is taken out. A stainless steel product manufactured through the technology has the high combination strength with plastic, and is good in firmness and high in drawing force.

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a stainless steel surface nanoscale treatment process. Background technique [0002] With the diversified development of electronic 3C products and household appliances, more and more products combining stainless steel and plastic are used in the market, and the performance and precision of the combination of stainless steel and plastic are increasingly demanding. The traditional stainless steel and plastic bonding technology is to use adhesives to bond stainless steel and plastic together at room temperature or in a heated environment. The combination obtained in this way has poor bonding strength, limited applications, and cannot meet the actual use strength requirements of the product. The stainless steel treated in this way has low bonding strength with the attachment plastic on the surface, poor firmness, and low pull-out force. [0003] Therefore, the pr...
