Description

Manufacturing method of inorganic flame retardant and its flame retardant {Process of Inorganic fireproof material and its fireproof material}

The present invention relates to a method for producing an inorganic flame retardant and a flame retardant obtained by the method.

Flame retardant is a material that has the effect of suppressing or mitigating combustion by improving materials such as wood, fiber, paper, urethane, etc., which are easy to burn, by physical or chemical methods. It functions by interfering with certain combustion stages such as heating, decomposition, protective film, endothermic action, and heat generation. Polymers and general paints, which are widely used in Korea as well as in the world, have various outstanding performances, but they are vulnerable in terms of internal combustion. It is strictly applied in the fields of equipment, automobiles, building materials, ship aircraft, and electric wire.

Currently, non-combustible and heat-insulating materials used in Korea are currently using organic chemical products such as gypsum board, styrofoam, glass wool, or ceramic fibers. These organic chemical products were easily burned in the event of fire, toxic gas was generated, and it was necessary to take asphyxiation, loss of life, and property loss. The demands for the development of building materials such as non-combustible materials and insulation materials have been recovered endlessly. The problem is reaching its limit.

In addition, the insulation materials used in construction, such as Styrofoam, glass fiber, urethane, and rock wool, have been widely used throughout the industry. However, as the main culprit of global warming and environmental destruction, products made from these materials will be turned away from consumers.

In particular, Styrofoam wastes take up to 500 years to decay in the ground and produce many toxic gases during combustion. Urethane foam is mixed with isocyanate and polyol and sprayed in the field to fill the blank or molded into a sheet, but it contains freon, pentane, and carbon dioxide, which proved to be very inadequate for environmental pollution. In recent years, it is not used.

Glass fiber also has good thermal insulation and processability, but it causes industrial illnesses due to fine dust when handling, which avoids manpower handling and damages the environment during waste disposal.

Conventional flame retardants are mainly halogen-based organic flame retardants, mainly bromine-based or chlorine-based, these are good in terms of effectiveness, but due to the serious problems in the environment and human body stability caused by harmful gases such as dioxin, Improvements as well as development of alternative materials are required.

In order to minimize the spread of flame and loss of life in the event of fire, the demand for flame retardants is increasing in various fields, and the requirements thereof are also diversified.

The recent trends and development directions related to flame retardants are summarized below.

In accordance with these domestic and international trends, we will develop an inorganic flame retardant in the form of liquid and powder that is environmentally friendly and has the stability of non-combustible raw materials.

By itself, it has strong binding power to combustible materials such as urethane, paper, fiber, plastics, and wood, and has high heat resistance and water absorption, and does not generate toxic gas during combustion. To provide an inorganic composition.

In addition, it is added to paints, resins, paints and pigments as necessary to provide an environmentally friendly inorganic compound-based flame retardant in the form of powders and water-soluble liquids that can be used as intermediates of final products having flame retardant properties.

The present invention is to add a high flame retardant property by adding to wood, synthetic resin or other various building materials.
