Low-cost fireproof material

Abstract

The invention belongs to a fireproof material and relates to a low-cost fireproof material which comprises the following raw materials in parts by weight: 20-25 parts of black mud powder or black mud particles or 55-70 parts of furnace slag powder or furnace slag particles or a mixture of black mud powder or black mud particles and furnace slag powder or furnace slag particles, 7-10 parts of industrial magnesium chloride, 7-10 parts of sillimanite powder, 7-10 parts of sepiolite, 7-10 parts of high-aluminum cement, 1-4 parts of polypropylene fibers, 3-5 parts of asbestos cellulose, 1-3 parts of a foaming agent and 1-3 parts of an AES active agent. The material is good in fireproof performance, is low in cost, is small in density and can be used for manufacturing fireproof equipment such as a fireproof door.

Description

technical field [0001] The invention belongs to fireproof materials, in particular to a low-cost fireproof material. Background technique [0002] The current fire doors are basically using perlite series products as the core material for fire doors. Perlite is a non-toxic, odorless, non-combustible and non-corrosive material. This product is mainly used for building roofs and walls. Thermal insulation, heat insulation; lightweight aggregate of building materials; various industrial equipment, pipeline insulation layer; agricultural and horticultural soilless cultivation, water and fertilizer conservation, etc., are widely used in petroleum, chemical, electric power, construction, metallurgy and other industries . The operating temperature of perlite is -256-800°C, and the fire-resistant temperature is low, which makes the fire doors produced by it far from those in Europe and the United States. Fire doors are of great significance as fire protection, so the fire-resistant...

Problems solved by technology

The new national standard GB12955-2008 implemented on January 1, 2009 has further improved the quality requirements for the production of fire doors, among which (Class A fire resistance time: 1.5h, Class B fire resistance time: 1.0h), "Door The maximum service temperature of fire doors in "Fire Resistance Test Methods for Roller Shutters" is 1200°C. The existing fire doors cannot meet the requirements of the new national standards. Therefore, it is urgent to find fire door materials with good fire performance and low manufacturing cost.

[0004] At present, there are many kinds of fire doors such as straw fire doors and sawdust fire doors on the market, but they have poor heat insulation performance, short fire resistance time, and are easy to catch fire, which cannot meet the requirements of the new national standards and the "Code for Fire Protection in Building Design"
