Process for bonding stainless steel and carbon steel composite plate

Abstract

This invention relates to a bonding process of non-corrosive steel carbon steel sandwich, which comprises the following steps: a) acid cleaning and derusting the carbon steel plate, surface cleaning the non-corrosive steel at the same time; b) bushing high-intensity adhesive on the surface of carbon steel plate or non-corrosive steel, and sticking them together; c) extruding the adhered non-corrosive steel and carbon steel plate, making them stick to sandwich; d) extruding the sandwich with planisher, and then cleaning excess adhesive dirt; e) forming roll bending type with rolling machine ,or forming plate type with guillotine.

Description

technical field

[0001] The invention relates to the technical field of metal reprocessing, in particular to a processing method for combining two metal plates into one. Background technique

[0002] At present, stainless steel and carbon steel composite panels are used for the metal shell, exterior decoration, guardrail pipes, and anti-theft doors and windows of the products. The advantage of this kind of composite plate is not only that the price is much cheaper than that of pure stainless steel plate, but also on the basis of retaining the beautiful appearance of stainless steel plate, it increases the strength and expands the scope of use.

[0003] There are currently only two production methods for stainless steel and carbon steel composite panels. The first method is the rolling method adopted by Yanghai Special Steel Co., Ltd., Zhuhai City, Guangdong Province: First, cut a 0.5 mm thick stainless steel plate into a small plate, coat a layer of medium with graphite as t...

Examples

Embodiment 1

[0020] The production steps are as above, except that the pickling agent used is dilute sulfuric acid, the cleaning agent is alcohol, and the adhesive is 502 cyanopropene.

Embodiment 2

[0022] The production steps are the same as Example 1, except that the pickling agent used is dilute hydrochloric acid, the cleaning agent is acetone, and the adhesive is 410 instant adhesive.

Embodiment 3

[0024] The production steps are the same as Example 1, except that the pickling agent used is dilute nitric acid, the cleaning agent is a commercially available cleaning agent, and the adhesive is 4110 instant adhesive.
