Fireproof, moistureproof, anti-corrosion and anti-cracking integrated smoke exhaust pipe

Abstract

Disclosed is a fireproof, moistureproof, anti-corrosion and anti-cracking integrated smoke exhaust pipe. The fireproof, moistureproof, anti-corrosion and anti-cracking integrated smoke exhaust pipe isa hollow pipe in an integrated structure; the pipe wall is made of inorganic pulp sheets; the inorganic pulp sheets are prepared from raw materials including magnesium oxide, magnesium chloride, sawdust, perlite, glass fiber grids, water, modifier and magnesite halogenide-resistant agent, wherein the modifier is prepared from phosphoric acid, magnesium sulfate heptahydrate, ferrous sulfate and aluminum sulfate; specifically, the raw materials for preparing the inorganic pulp sheets are composed of, by weight part, 3-5 parts of magnesium oxide, 3-5 parts of magnesium chloride, 1-3 parts of sawdust, 1-3 parts of perlite, 0.1-1.0 part of modifier, 0.1-0.5 part of magnesite halogenide-resistant agent and water as balance. The fireproof, moistureproof, anti-corrosion and anti-cracking integrated smoke exhaust pipe has the advantages that heat resistance and high fireproof performance can be achieved, and the requirements on safe fire protection can be met; the sheets are moistureproof andless prone to causing breakage or collapse of the smoke exhaust pipe; cracks as well as shortcomings such as gas and oil leakage, wall decorative surface pollution and influence on overall appearancecan be avoided; by means of integrated installation, time and labor can be saved, and labor cost can be reduced; sense of safety and comfort of residents can be enhanced.

Description

technical field [0001] The invention relates to a housing construction accessory, in particular to a fire-proof, moisture-proof, anti-corrosion, anti-crack integral smoke exhaust pipe. Background technique [0002] With the rapid development of my country's economy and technology and the improvement of people's living standards, people's living conditions have also been greatly improved. In recent years, Chinese residents generally live in modern new buildings. There are pipes for smoke exhaust or exhaust to prevent cooking fumes from the kitchen or odor from the bathroom from entering the room, polluting the air, corroding household appliances in the room, and damaging human health. At present, the walls of kitchens and bathrooms in various buildings are equipped with smoke exhaust pipes for exhausting oil fume or hot gas. Existing smoke exhaust pipes are generally assembled from plastic panels, wood-based panels or cement mortar panels. Exhaust and smoke exhaust pipes have...

Problems solved by technology

At present, the walls of kitchens and bathrooms in various buildings are equipped with smoke exhaust pipes for exhausting oil fume or hot gas. Existing smoke exhaust pipes are generally assembled from plastic panels, wood-based panels or cement mortar panels. Exhaust and smoke exhaust pipes have the following defects: 1. Poor fire resistance, easy to burn, and fail to meet the requirements of safety and fire prevention; Cracks not only cause air leakage and oil leakage, but also cause cracks in the wall finish or falling off of tiles, which affect the overall appearance of the house; 4. Installation is troublesome and increases labor costs
