Problems solved by technology

For example, adding graphite particles to it can achieve the fire protection level of B2, but it still cannot solve the phenomenon of its melting drop
The prior art CN10176114A discloses a flame retardant EPS foam with a method of adding a flame retardant and an adhesive with a particle size of 1-50 μm, and the surface of the expandable polystyrene beads and the primary foam particles Coating improves the insulation and flame retardancy of expanded polystyrene foam. The flame retardant used is metal or non-metal oxide, but because the flame retardant used is compatible with the polystyrene shot Poor performance, the mechanical properties of the prepared polystyrene foamed materials are difficult to meet the requirements of use, and this technology is only for expanded polystyrene, not suitable for all flame retardant insulation materials

Abstract

The invention relates to a flame-retardant thermal-insulation composition which is prepared from the following raw materials in parts by weight: 5-10 parts of silicate, 2-7 parts of phosphate, 1-3 parts of silicon dioxide, 1.0-2.0 parts of magnesium oxide, 0.5-1.5 parts of kieselguhr and 0.5-1.5 parts of water. The flame-retardant thermal-insulation composition can be used for coating various thermal-insulation particles, has favorable compatibility, and can enable some coated combustible organic materials with small heat conductivity coefficient and favorable thermal insulation effect to form a closed high-polymer particle-structure thermal-insulation material. The invention also relates to a thermal-insulation material and thermal-insulation board comprising the flame-retardant thermal-insulation composition and a preparation method thereof.

Description

【Technical field】 [0001] The invention belongs to the field of construction, and relates to a flame-retardant thermal insulation composition, a thermal insulation material containing the same and a preparation method. 【Background technique】 [0002] At present, in the field of wall thermal insulation, thermal insulation materials are widely used: EPS board (expanded polystyrene board); XPS board (extruded polystyrene board); polyurethane board; polystyrene board; inorganic insulation board, etc. . Among them, EPS boards, XPS boards and polyurethane boards are the main ones, accounting for more than 80% of the total external wall insulation. EPS boards and XPS boards are essentially polystyrene boards, and the main materials of both are polystyrene; they are thermoplastic organic foam boards. The use of these thermal insulation materials in buildings provides effective thermal insulation for building energy conservation, but due to the defects of these thermal insulation bo...
