Embodiment 1

[0016] A steel plate 1 enters the glue coating machine 3 from the conveyor belt 2, and after being coated with a layer of polymer damping resin glue by the glue coating machine 3, it enters the lower drying tunnel 5 of the heating furnace 4 for heating, so that the solvent in the resin is volatilized and the resin is mainly used. agent activation. At the same time, another steel plate 13 is input from the conveyor belt 2 into the upper drying tunnel 6 of the heating furnace 4 for preheating, the lower drying tunnel 5 and the upper drying tunnel 6 respectively heat the steel plates 1 and 13 for 1 to 3 minutes, and the The steel plates are sent out of the heating furnace 4 at the same time, automatically aligned and laminated by the mechanical control of the prior art, and the steel plates 1 and 13 are hot-compressed and laminated sequentially through five pairs of thermal lamination rollers 8, and the damping resin layer between the steel plates 1 and 13 is simultaneously Heati...

Embodiment 2

[0018] The processing steps of this embodiment are the same as those of Embodiment 1. The main materials and process conditions of this embodiment are: steel plates 1 and 13 are cold-rolled steel plates with a thickness of 1 mm; The film thickness is 65 μm; the temperature of the heating furnace 4 is 200°C, and the heating is for 2 minutes; among the five pairs of hot composite rolls, the surface temperature of the first pair of rolls is 300°C, and the surface temperatures of the second to fifth pair of rolls are respectively 450°C, The time for the steel plate to pass through the first to fifth pairs of pressure rolls is 18 seconds respectively; the surface temperature of the sixth pair of cold composite rolls is 80°C, the time for the steel plate to pass through the pair of pressure rolls is 20 seconds, and each pair of rolls adopts conventional linear pressure. The peel strength value of the prepared composite damping steel plate is 80N / cm, the tensile shear strength is 15M...

Embodiment 3

[0020] The processing steps of this embodiment are also the same as that of Embodiment 1. The main materials and process conditions are: steel plates 1 and 13 are cold-rolled steel plates with a thickness of 1mm; the damping resin is the same as that in Example 1 or Example 2; , the surface temperature of the first pair of rolls is 180°C, the surface temperature of the second to fifth pair of rolls is 250°C, and the time for the steel plate to pass through the first to fifth pair of rolls is 30 seconds respectively; the surface temperature of the sixth pair of cold composite rolls The temperature is 50°C, the time for the steel plate to pass through the pair of rollers is 20 seconds, and each pair of rollers adopts conventional linear pressure. The peel strength value of the prepared composite damping steel plate is 40N / cm, the tensile shear strength value is 6.5MPa, and the vibration damping characteristic η value is 0.20.

Abstract

The compound damping steel plate making process and apparatus adopts one identical heating furnace with upper stoving channel and lower stoving channel for preheating steel plate and heating glued steel plate separately, and five pairs of heating and laminating rolls to roll and combine two steel plates, with the damping resin layer between two steel plates being heated, pressurized and cured simultaneously. The present invention has effectively lowered power consumption, excellent steel plate laminating performance and simplified technological process, and may be applied widely in making compound damping steel plate with high molecule resin as the damping and adhering layer.

Description

technical field [0001] The invention relates to the technical field of steel plate manufacturing, in particular to a manufacturing method and a manufacturing device of a composite steel plate with vibration and noise reduction functions using polymer resin as a damping and bonding layer. Background technique [0002] The closest prior art with the present invention is the Chinese invention patent whose application number is 00115432.X, titled "Production Technology of Vibration Damping Composite Steel Plate". The production process includes the production method of the composite steel plate and a set of manufacturing equipment for the composite damping steel plate to realize the production method. After a layer of polymer damping resin is rolled on a steel plate by a roller coater, it enters a heating Furnace heating to volatilize the resin solvent or activate the resin main agent, and at the same time put the other steel plate into another heating furnace for preheating; th...
