High-smoke suppression and high-oxygen index phenolic aldehyde fire-proof heat-preserving board and preparation method thereof

Abstract

The invention relates to a high-smoke suppression and high-oxygen index phenolic aldehyde fire-proof heat-preserving board and a preparation method thereof and belongs to the technical field of a building fire-proof material. The high-smoke suppression and high-oxygen index phenolic aldehyde fire-proof heat-preserving board comprises the following components in parts by mass: 100 parts of phenolic resin, 10 to 20 parts of expansive fire retardant, 5 to 10 parts of liquid fire retardant, 5 to 8 parts of coal ash, 1 to 2 parts of tiny silicon powder, 1 to 2 parts of magnesium hydroxide, 5 to 7 parts of foaming agent, 5 to 7 parts of foam stabilizer and 20 to 30 parts of curing agent. The preparation method of the high-smoke suppression and high-oxygen index phenolic aldehyde fire-proof heat-preserving board comprises the following steps of 1) preparing a mixed slurry, i.e. (1) optionally selecting a formula, (2) mixing the phenolic resin and the liquid fire retardant, (3) mixing the expansive fire retardant, the hollow coal ash, the magnesium hydroxide and the tiny silicon powder, and adding the mixture into the mixed liquid, (4) adding the foaming agent and the foam stabilizer, and uniformly stirring the materials, and (5) adding the curing agent, stirring the materials, and filling the mixture into a die; and 2) molding and curing to obtain the fire-proof heat-preserving board. The fire-proof heat-preserving board has the advantages of convenience in construction, good fire resistance, low water absorption per volume, capability of meeting the requirements of high smoke suppression and high oxygen index of inner and outer wall heat-preserving boards, and the like.

Description

technical field [0001] The invention belongs to the technical field of building fireproof materials, and in particular relates to a phenolic fireproof heat preservation board with high smoke suppression and high oxygen index and a preparation method thereof. Background technique [0002] Currently, one of the major sources of energy consumption in buildings is the loss of energy through the materials that make up the building envelope. In order to prevent energy loss, the application of thermal insulation materials is the most direct and effective way to save energy in buildings. Building insulation materials are mainly divided into two categories: organic and inorganic. Organic and inorganic insulation materials can be used alone, in combination or with other materials after proper compounding, thus forming a variety of building insulation materials and building external insulation systems. Phenolic foam is an organic hard foam insulation material, which has the dual advan...

Problems solved by technology

The oxygen index and smoke suppression degree of the phenolic insulation boards currently used cannot meet the current national requirements for thermal insulation materials for interior and exterior walls of buildings. This is the main problem restricting the application of phenolic insulation materials.
