Problems solved by technology

However, due to its poor fire performance, this product can only meet the national B1 fire protection standard at present, and it will produce deadly poisonous gas when burned. Although rock wool has the function of heat insulation and A-level fire prevention, it belongs to the industry with high energy consumption, high emission and high pollution. It wastes resources and affects the environment. It cannot prevent moisture and absorb water, which is harmful to human health. The construction cost is high. non-degradable

Embodiment Construction

[0043] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0044] see figure 1 , the preparation method of a kind of nano fireproof polystyrene foam board of the present invention, comprises following synthetic steps:

[0045] S1. Mixing of raw materials: 40-50 parts of polystyrene raw material, 40-50 parts of fumed silica, 2-5 parts of nano-aerogel, and 2-5 parts of graphite are mixed in parts by mass. Fully mix ethylene and 2-10 parts of white high-temperature ceramic glaze;

[0046] S2, heating and stirring: put the mixed material in a stirring device with electric heating function to heat up and stir, so that the material is fully mixed, the temperature in the stirring device is 50-70 ° C, and the stirring time is 10-20 minutes;

[0047] S3. Baking and bonding: put the evenly stirred polystyrene material in the oven and continue to heat up and bake to make the polys...

Abstract

The invention discloses a nano-fire-proofing polystyrene foam board and a preparation method thereof. The nano-fire-proofing polystyrene foam board comprises the components of a polystyrene raw material, fumed silica, nanometer aerogel, graphene and white high temperature ceramic glaze. The fumed silica, the nanometer aerogel, the graphene and the white high temperature ceramic glaze are added to the polystyrene raw material so that the conventional polystyrene foam board is modified; therefore, the polystyrene foam board can also achieve a fire-proofing effect on the premise of the conventional heat insulation function. The nano-fire-proofing polystyrene foam board and the preparation method thereof, disclosed by the invention, have the advantages that the polystyrene foam board having the heat insulation function and capable of realizing A-grade fire-proofing modification is produced through formula adjustment, the fire safety is enhanced, the heat insulation material cost is reduced, a purpose of saving energy and reducing emission is achieved and a technical blank is filled.

Description

technical field [0001] The invention relates to the technical field of fireproofing, heat insulation and heat preservation of buildings, in particular to a nano-fireproof polystyrene foam board and a preparation method thereof. Background technique [0002] Polystyrene foam board - also known as foam board, EPS board is composed of expandable polystyrene beads containing volatile liquid foaming agent, which is a white object heated and formed in a mold after heating and pre-expanding. The structural characteristics of closed cells are mainly used for building walls, roof insulation, composite panel insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc. are very widely used. [0003] Polystyrene foam board is cheap to manufacture and one of the materials with the best thermal insulation effect. It is widely used in construction and packaging fields. However, due to its poor fire performance, this product can only mee...
