Problems solved by technology

However, this production process is relatively simple, only one kind of polymer resin can be coated, and only double-layer composite panels made of a single polymer resin can be produced; and this production process does not treat the surface of the raw material strip before compounding And protection, affecting the bonding performance of the product
The peel strength of the stainless steel / galvanized composite film plate or the stainless steel / aluminum composite film plate produced by this method is generally slightly higher than 50N / cm, and the product bonding strength is low, and the product is easy to fold in the subsequent hemming process or after a period of time. Cracking occurs, resulting in quality hazards

Embodiment 1

[0019] Referring to the figure, after the upper stainless steel coil and the lower aluminum coil are processed by the surface treatment unit 6, the chemical coating machine 11 coats a layer of chemical coating liquid on the composite surface of the upper stainless steel coil and the composite surface and exposed surface of the lower aluminum coil , After drying by the chemical coating drying oven 12; then the roller coater 14 coats a layer of liquid polymer resin on the surface to be compounded, and the back coater 15 coats the liquid polyurethane coating on the exposed surface of the lower aluminum coil and enters the T shape Drying furnace 16 performs polymer resin, paint solvent volatilization and preheating of raw material strips. The temperature in the furnace is 200°C; and the compounding unit 17 completes the compounding. The rolling pressure of the compounding roller of the compounding unit is 50t; after spraying The cooling unit 18 is forced to cool to normal temperatur...

Embodiment 2

[0022] Referring to the figure, after the upper layer of stainless steel coil and the lower layer of galvanized coil are processed by the surface treatment unit 6, the chemical coating machine 11 coats the surface of the stainless steel to be laminated and the surface of the galvanized coil each with a layer of chemical coating liquid. The chemical coating drying oven 12 is dried; then a layer of liquid polymer resin is coated on the upper stainless steel surface to be laminated and the galvanized coil surface to be laminated by the roller coater 14 respectively. The back coater 15 does not coat the protective coating and enters The T-shaped drying furnace 16 performs the volatilization of the polymer resin solvent and the preheating of the raw material strip, and the preheating temperature is 280℃; and the compounding unit 17 completes the compounding, and the rolling pressure of the compounding roller of the compounding unit is 80t; then it passes through the cooling unit 18 i...

Embodiment 3

[0025] Referring to the figure, after the upper layer of stainless steel coil and the lower layer of aluminum coil are processed by the surface treatment unit 6, the chemical coating machine 11 coats a layer of chemical coating liquid on both the stainless steel and aluminum coil surfaces to be composited. Drying in the drying oven 12; then the roller coater 14 coats a layer of liquid polymer resin on the upper stainless steel composite surface and the lower aluminum coil composite surface respectively. The back coater 15 does not apply environmentally friendly paint and enters the T-shaped drying Dry furnace 16 performs polymer resin solvent volatilization and preheating of raw material strips. The temperature in the furnace is 380°C; and the compounding unit 17 completes the compounding, and is forced to cool to room temperature through the cooling unit 18, and finally passes through the finishing unit 22 for finishing. Complete processing and complete finished product collect...

Abstract

The invention belongs to the technical field of sheet metal production and relates to a production method for a stainless steel film plate. The production method comprises the following steps: performing surface cleaning and surface activating treatment on a stainless steel roll and a lower-layer galvanized coil (or aluminum roll) and then coating a layer of liquid macromolecule resin by using a roll coater; using a middle T-shaped drying oven for drying the strip and the macromolecule resin, compounding upper and lower layers by using a compounding unit and cooling by using a cooling unit; lastly, trimming, smoothening and coiling for collecting. The invention has the beneficial effects: due to the application of a three-layer type structure and the T-shaped drying oven, the workshop space is reasonably utilized, the layout of the whole production line is more compact and reasonable, the length of the production line is saved and the investment cost and the production cost are saved.

Description

Technical field [0001] The invention belongs to the technical field of sheet metal production, and relates to a method for producing a stainless steel film sheet. Background technique [0002] In the existing production method of double-layer vibration-damping composite plate (see Baosteel "Production Process of Vibration-damping Composite Steel Plate", patent publication number CN1268411A), the main method is to coat a layer of polymer resin on the surface of a single steel plate, and Another steel plate is preheated, and then through the preheating furnace and curing furnace to complete the volatilization and curing reaction of the polymer resin solvent, and through operations such as hot rolling and cold rolling, the production of composite materials is completed. However, this production process is relatively simple, only one type of polymer resin can be coated, and only a double-layer composite board made of a single polymer resin can be produced; and this production process...
