A process for adding expanded graphite to core raw materials on a color steel insulation board production line

Abstract

A process for adding expanded graphite to the core material raw material on the color steel insulation board production line, including using a batching tank for batching, stirring and transporting to the storage tank, and sending it to the POLY unit for storage after stirring; sending the isocyanate stored in the ISO unit into The first working tank, after the stirring is completed, it is sent into the distribution mixer through the metering pump; the polyol composition containing expanded graphite stored in the POLY unit is sent to the second working tank, and sent to the distribution mixer after stirring; mixed with expanded graphite The polyol composition and isocyanate are mixed by a cloth mixer and then foamed. The present invention establishes a production process suitable for adding expanded graphite to polyol raw materials on the production equipment of polyurethane double-sided color steel insulation board continuous line double crawler machine, including a device for adding expanded graphite, graphite is added to the raw material through a batching unit Neutralize and stir, and then through the stirring of the constant temperature unit and the mixing of the mixing unit, it ensures the uniform mixing of graphite in the raw materials and the quality of the product.

Description

technical field [0001] The invention belongs to the field of color steel plate production, and in particular relates to a process for adding expanded graphite to core material raw materials on a color steel heat preservation plate production line. Background technique [0002] Color steel sandwich panel is a common product in the current building materials, not only can be very good flame retardant, sound insulation, but also environmentally friendly and efficient. The color steel sandwich panel is made of upper and lower layers of metal panels and a middle polymer heat insulation core. It has the characteristics of easy installation, light weight, environmental protection and high efficiency, and the closed-cell molecular structure used in the filling system can prevent condensation of water vapor. The color steel sandwich panel not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decorative properties and corrosion ...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no technology in the industry to specifically add graphite to the raw materials of polyurethane color steel insulation boards. Therefore, a process of adding expanded graphite to the core material raw materials on the color steel insulation board production line is designed to improve product quality.
