Production process of composite metal plastic belt

Abstract

The invention relates to a production process of a composite metal plastic belt. The whole set of production process comprises the steps of material selection, uncoiling, adhesion, preheating, hot-lamination composition, hot-drying solidification, cooling, loop storage, coiling and coil unloading. The production process of the composite metal plastic belt has the advantages that the comprehensive performance of a composite metal plastic belt product is stable; the composite metal plastic belt product does not stick to a film; the peeling strength between a steel belt and a plastic film is high; the production efficiency is remarkably improved; resources can be saved.

Description

technical field [0001] The invention relates to a production process of a steel-plastic composite belt, which belongs to the application field of thermal processing and manufacturing. Background technique [0002] At present, the production of steel-plastic composite belts adopts preheating, thermal lamination, cooling, and other auxiliary equipment to complete the composite of plastic film and chrome-plated steel belts, but the steel-plastic composite belts made by the existing technology have certain defects Disadvantages: First, the comprehensive performance is unstable and greatly affected by the ambient temperature. In summer, the temperature is too high during winding due to insufficient cooling, and the film is easy to stick. In winter, the peeling strength between the plastic film and the chrome-plated steel strip is low due to the low temperature; The reason is that the preheating oven and the post-treatment heat curing oven are too short, and the speed of the unit ...

In summer, the temperature is too high during winding due to insufficient cooling, and the film is easy to stick. In winter, the peeling strength between the plastic film and the chrome-plated steel strip is low due to the low temperature; The reason is that the preheating oven and the post-treatment heat curing oven are too short, and the speed of the unit is low, which affects the production capacity; the third is that the winding machine needs to be shut down when changing rolls, which not only makes the production efficiency low but also causes a large waste of resources (because the shutdown will lead to preheating To the winding section, the steel-plastic composite tape is unqualified)
