Abstract

The invention relates to an inorganic ecological fireproof blast pipe board, and a production method and an application thereof. The fireproof blast pipe board is produced from, by weight, 100 parts of gelling powder, 60-86 parts of a compounded glue, 0-40 parts of a mineral filler, 0.8-10.0 parts of reinforced fibers and 0-5.8 parts of a fiberglass mesh, wherein the gelling powder is prepared through compounding a calcium-containing inorganic matrix, alga powder and a magnesium-based gelling material according to a weight ratio of (10-40):(8-28):(32-72). The invention further discloses the production method and the application of the fireproof blast pipe board. The fireproof blast pipe board microscopically has a network cross connection structure, macroscopically has a smooth surface anda good flexibility, and solves the general problems of rough surface, brittle cracking and the like of existing fireproof boards and products; and above components are reasonably matched, so the fireproof blast pipe board has air purifying, bacterium resisting and humidity regulating effects and other ecological properties, and also has the efficacy of resisting water and moisture, reducing the weight and accumulating heat.

Description

technical field [0001] The invention belongs to the technical field of green ecological environment building materials, and in particular relates to the preparation and application of an inorganic fireproof air duct board. Background technique [0002] There are about 100 million square meters of new ventilation ducts in my country every year. The traditional use of galvanized iron ducts has four major disadvantages: easy to rust, loud noise, 10% air leakage, and 10% energy loss due to cold and heat bridges. Later, in order to solve the shortcomings of iron sheet air ducts rusting, FRP air ducts appeared. However, FRP air ducts are organic materials, which can burn and spread rapidly in case of fire, and produce thick smoke and poisonous gas. Therefore, GB50045 "Code for Fire Protection Design of High-Rise Buildings" It is stipulated in the regulations: "Non-combustible materials should be used for ventilation pipes." Since then, a large number of researches have focused on ...
