Abstract

The utility model belongs to a central air conditioning, fire protection and smoke exhaust magnesite foam insulation PLASTIC LAMINATED, including various steel deck (1) and (b) aluminium foil (b) layer (3), characterized in that bonds between various steel deck (1) and (b) aluminium foil (b) layer (3) has magnesite foaming layer (2). Magnesite foaming layer (2) thickness be L, L=1.0 -2.0cm. The utility model discloses a satisfy GB8624's fire prevention heat preservation national standard, filled the blank of the compound tube material of internal central air conditioning air pipe, the low price, material resource is sufficient, preparation simple process.

Description

Central air-conditioning, fire control smoke exhausting magnesite foamed heat insulating PLASTIC LAMINATED

Technical field

The utility model belongs to PLASTIC LAMINATED, particularly a kind of central air-conditioning, fire control smoke exhausting magnesite foamed heat insulating PLASTIC LAMINATED.

Background technology

Insulated fire plate is a kind of sheet material of the processing and fabricating of central air-conditioning composite air duct, and the thickness of usual sheet material is 2 ~ 2.5 centimetres, and upper and lower surface is made by thin aluminum top and color steel, and intermediate layer is heat insulation core material.The polyurethane composite air duct produced from Italian ALP in 2002 enter domestic since, revolutionizing ventilating duct of central air conditioner by iron duct is the situation of main material. due to composite air duct, the cost of material is low, lightweight, processing technology thereof is simple, and the advantages such as the processing and fabricating cycle is short are favored by user deeply.

But polyurethane composite air duct is after entering domestic ventilating duct of central air conditioner market, be proven and have the following disadvantages, fire-protection rating is low, and difficult combustion C level is assert in polyurethane composite air duct core fire-protection rating current NFA evaluating center. require that ventilating duct of central air conditioner core does not fire A level according to national Building Fire Protection specification GB50016.Shandong University one professor have developed phenol aldehyde modified foamed heat insulating sheet material .2010 NFA evaluating center to the identification of metlbond compound air pipe core fire-protection rating on the basis of polyurethane composite air duct, metlbond compound air pipe core fire-protection rating difficult combustion B1 level, the standard-required of GB50016 can not be met, more can not make fire control smoke exhausting pipeline.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, there is provided a kind of thermal conductivity factor at 0.045W/(MK), good effect of heat insulation, ventilating duct of central air conditioner can be made, fire control smoke exhausting pipeline can be made again, reach national GB8624 fireproof heat insulating standard central air-conditioning, fire control smoke exhausting magnesite foamed heat insulating PLASTIC LAMINATED.

The technical scheme that the utility model technical solution problem adopts is: a kind of central air-conditioning, fire control smoke exhausting magnesite foamed heat insulating PLASTIC LAMINATED, comprise color steel layer and aluminium foil layer, be characterised in that at color steel layer and aluminium foillayer intennediate bond has magnesite foaming layer.

The thickness of described magnesite foaming layer is L, L=1.0-2.0cm.

The beneficial effects of the utility model are: this utility model meets the fireproof heat insulating national standard of GB8624, have filled up the blank of domestic ventilating duct of central air conditioner multiple tube material, cheap, and material resources is sufficient, and manufacture craft is simple.
