Manufacturing method of grade-A2 fireproof aluminum composite plate

Abstract

The invention discloses a manufacturing method of a grade-A2 fireproof aluminum composite plate. The grade-A2 fireproof aluminum composite plate is manufactured from 83kg-93kg of calcium carbonate, 130kg-142kg of silicon micro-powder, 87kg-97kg of quartz sand, 10kg-15kg of pearlite, 7kg-12kg of polypropylene staple fiber, 40kg-50kg of silicon dioxide, 58kg-67kg of aluminium hydroxide, 12kg-27kg of zinc molybdate and 135kg-145kg of acrylic based emulsion. The method comprises the following steps of: 1, preparing materials; 2, discharging and pasting non-woven fabrics; 3, roasting, stripping the non-woven fabrics and rolling; 4, cooling, grinding, gluing and roasting; and 5, adhering, cooling and shearing. By adopting the manufacturing method of the fireproof aluminum composite plate, liquid materials are roasted into a solid state to form the core materials through roasting for eight times by an oven and rolling by a rolling mill, and the core materials and the aluminum plate are difficult to delaminate under the high-temperature condition, and the fireproof intensity is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a fireproof board, in particular to a method for manufacturing an A2 grade fireproof aluminum composite board. Background technique [0002] At present, in the general aluminum-plastic panel, because the plastic core material is made of flammable polyethylene as the base material, when the fire detection is carried out in the vertical combustion furnace, the heat transfer speed of the aluminum plate is very fast, and the core material at high temperature It is easy to delaminate from the aluminum plate, so that the polyethylene is in direct contact with the flame at high temperature, and at the same time, the polyethylene is easy to burn and drip, thus igniting a big fire. In addition, the indoor and outdoor building decoration materials are flammable, resulting in frequent fires and endangering people's lives and property. It has caused huge losses and cannot meet the national A-level indicators, so ...

Problems solved by technology

[0003]The A-level fire-resistant aluminum-plastic panel currently achieved is an energy-saving and environmentally friendly product, which is suitable for airports, stations, subways, stadiums, shopping malls, and offices. Buildings, high-end cultural and entertainment centers and other public places, because the slurry is directly injected into the mold and then heated and pressurized by the traditional method, the fire protection level cannot reach the national A2 standard, and there are still potential safety hazards
