Abstract

The invention relates to the technical field of fireproof and thermal insulation materials, in particular to a fireproof thermal insulation board and a preparation method thereof. Its board body is made of polystyrene particles, and the surface of the board body is coated with a mixed flame retardant. The flame retardant is prepared from the following components by weight: thermosetting resin: 10‑40 parts; inorganic powder: 0.5-20 parts; elastic toughening agent: 1-5 parts; waterproofing agent: 1-3 parts; curing agent: 2-10 parts; water: 2-6 parts, mix the above components in a mixing tank in proportion be made of. The preparation method of the fireproof insulation board is to pre-foam the polystyrene particles and dry the polystyrene particles, then carry out the coating particle molding treatment, and finally cut and pack the board according to the required size. The fireproof and thermal insulation board prepared by the invention has cheap and easy-to-obtain raw materials, good flame retardancy, low smoke toxicity, low density, high compressive strength, low thermal conductivity, good weather resistance, and is harmless to the environment and human body.

Description

technical field [0001] The invention relates to the technical field of fireproof and thermal insulation materials, in particular to a fireproof thermal insulation board and a preparation method thereof. Background technique [0002] The combustion of polystyrene is a very intense and complex thermal oxidation reaction, characterized by thick smoke or blazing flames. The general process of combustion is that under the continuous heating of an external heat source, polystyrene first undergoes a free radical chain degradation reaction with oxygen in the air to produce volatile combustibles, which will ignite and burn when they reach a certain concentration and temperature. Part of the heat released by the combustion is supplied to the degrading polystyrene, further aggravating its degradation, producing more flammable gases, and the flame will spread rapidly in a short period of time to cause a big fire. Due to the occurrence of many building insulation fire incidents in recen...
