Abstract

The invention relates to a high-performance fireproof composite sheet material and a preparation method thereof. The high-performance fireproof composite sheet material comprises two upper and lower steel plates and a fireproof layer arranged between two steel plates, wherein the fireproof layer and two upper and lower steel plates are bonded by a high-viscosity adhesive which is composed of a component A and a component B; the component A is prepared from the following raw materials by weight: 80 to 100 parts of modified phenolic resin, 80 to 100 parts of modified epoxy resin, 40 to 60 partsof butyronitrile, 40 to 50 parts of polyvinyl butyral, 40 to 50 parts of a silane coupling agent, 5 to 10 parts of inorganic fireproof fiber, 2 to 5 parts of hollow microsphere and 2 to 5 parts of expanded vermiculite; and the component B is prepared from the following raw materials by weight: 30 to 50 parts of sodium silicate, 10 to 20 parts of hexamethylenetetramine, 10 to 20 parts of magnesiumoxide powder, 10 to 15 parts of high aluminum powder and 1 to 1.5 parts of sodium hexametaphosphate. Compared with the prior art, the sheet material provided by the invention has significant fire-retardant performance, can be rapidly expanded or carbonized once a fire disaster occurs, has long duration of fire resistance and high surface strength, and is insusceptible to cracking.

Description

technical field [0001] The invention relates to a composite board, in particular to a high-performance fireproof composite board and a preparation method thereof. Background technique [0002] The use of the board is relatively extensive, and the characteristics of the board also have a greater impact on the use of the board. There are many types of boards, with different materials. The fire rating of the board is an important technical indicator of the safety performance of the board. At this stage, ordinary boards have a low fire rating and poor fire performance, which cannot effectively meet the needs of the market. [0003] In recent years, fires caused by insulation boards in my country have been heard from time to time, and the frequency and the huge loss of personnel and property are shocking. Looking at the insulation board market, the currently commonly used insulation boards mainly include polystyrene boards, extruded polystyrene boards, and polyurethane Foam, et...
