Embodiment Construction

[0012] The present invention will be further described in detail according to the examples below.

[0013] Such as Figure 1~3 As shown, the polymer composite fireproof smoke exhaust duct is composed of a range hood or exhaust fan, a fire check valve 2 and a roof hood 3 . The fire check valve 2 is arranged on the outer, middle and upper part of the exhaust duct 1, and is connected with the range hood or the exhaust fan, and the roof air cap 3 is arranged on the upper end of the exhaust duct 1. The roof hood can also be designed as a round cap.

[0014] The fire check valve 2 can prevent the flue gas from flowing back, and its valve is detachable, which is convenient for cleaning oil. At the same time, it can effectively prevent the high-temperature smoke from spreading to other floors in the event of a fire.

[0015] The preparation method of the polymer composite fire-proof flue gas duct base material is to use 35% cement, 17% sand, 22% sub-stone as aggregate, and 1.5% epo...

Abstract

The invention discloses a polymer composite fireproof-type dry powder mortar base material and a preparation method thereof. A polymer composite fireproof-type smoke exhaust duct is composed of an air suction device, a fireproof check valve and a roof hood, wherein the fireproof check valve is arranged at the external middle-upper part of the exhaust duct and is connected with the air suction device, and the roof hood is arranged at the upper end part of the exhaust duct. The preparation method of the base material of the polymer composite fireproof-type smoke exhaust duct comprises the steps of: at first, taking 30 to 40% of cement, 15 to 20% of sand and 20 to 25% of stone as aggregate, and then adding 1 to 2% of high polymer organic polymer powder, a small amount of additive for curing, water removal and defoaming and fireproof material to produce, by specific equipment, specific raw material for manufacturing the smoke exhaust duct, which is called the base material for short and used for be manufactured into thin-wall member. The base material has the advantages of excellent fireproof property, good corrosive, alkaline, impact, compression and bending resistance, high bonding strength, and high rupture strength, and the service life of the product made of this base material is 2 to 3 times as long as that of common sand mortar products.

Description

technical field [0001] The invention relates to an exhaust duct, in particular to a polymer composite fireproof smoke exhaust duct and a preparation method thereof. Background technique [0002] In recent years, the exhaust flue market has been relatively chaotic. Single, double, triple, and models are extremely irregular. Due to the different materials used by manufacturers, they do not comply with relevant national industry regulations, seriously disrupting the market, and causing great harm to the national construction industry and people. Daily life brings great harm. The production base material of the exhaust duct of the present invention is used for the production of a single exhaust duct, and is applicable to exhaust ducts for mechanical exhaust of multi-storey and high-rise residential kitchens and toilets with forty floors and below forty floors, and can also be used Used as other ventilation ducts. Contents of the invention [0003] The invention provides a ki...
