A2 level fireproof core board and manufacturing method thereof

Abstract

The invention discloses an A2 level fireproof core board and a manufacturing method thereof. The core board consists of a fireproof core layer and a polymeric membrane bonding material, wherein the fireproof core board is of a sheet structure, and the sheet can be rolled into a roll. The method comprises the following steps: batching, discharging, baking, binding, cooling and rolling. The internal density of the core board is increased, so as to improve fireproof strength and enable combustion performance to meet the requirements of A2 level; the sheet can be rolled into the roll to be packed, other customers can machine the roll into a fireproof composite board according to self production requirements by combining with a metal plate as an aluminum plate, a copper plate or a stainless steel plate, as a result, the production cost is reduced, the sources are saved, and batch production is facilitated.

Description

technical field [0001] The invention relates to a fireproof core board and a manufacturing method thereof, in particular to an A2 grade fireproof core board which can be manufactured by rolling the core board and a manufacturing method thereof. Background technique [0002] At present, the plastic core material uses the flammable material polyethylene as the base material. Its disadvantage is that when the fire detection is carried out in the vertical combustion furnace, the core material and the aluminum plate are easy to delaminate at high temperature, causing the polyethylene to be separated from the flame at high temperature. In direct contact, polyethylene is easy to burn and drip, which can ignite fires. In addition, indoor and outdoor building decoration materials are flammable, resulting in frequent fires. At present, although the fire-resistant aluminum-plastic panels involved are energy-saving and environmentally friendly products, due to Directly inject the slurry...

[0002] At present, the plastic core material uses the flammable material polyethylene as the base material. Its disadvantage is that when the fire detection is carried out in the vertical combustion furnace, the core material and the aluminum plate are easy to delaminate at high temperature, causing the polyethylene to be separated from the flame at high temperature. In direct contact, polyethylene is easy to burn and drip, which can ignite fires. In addition, indoor and outdoor building decoration materials are flammable, resulting in frequent fires. At present, although the fire-resistant aluminum-plastic panels involved are energy-saving and environmentally friendly products, due to Directly inject the slurry into the die and adopt the traditional method of heating and pressurizing, its strength is not enough, the fire resistance is not high, there are still potential safety hazards, and it cannot meet the market demand. In addition, no matter whether the plastic core material is made by the traditional method Fire-resistant aluminum-plastic panels, the core structure of which cannot reach A2-level fire resistance, and its own structure cannot be made into a specific shape. In the finished product, it is integrated with aluminum plates or other metal plates for transportation, which increases costs and reduces fire resistance. The scope of use of the core board is not easy to promote and apply
