Abstract

The invention provides a production process of an inorganic modified polyphenyl granule incombustilble heat insulation plate, and relates to the field of a building material. The production process comprises the following steps of adding magnesium oxide powder into a magnesium chloride solution; after the uniform stirring at the normal temperature, adding polyphenyl particles, expanded perlite, reinforced fiber, aluminum hydroxide and water glass; performing stirring at the normal temperature; then, adding polyvinyl acetate emulsion, dimethyl methylphosphate and tri(2-chloroethyl) phosphate; performing stirring at the normal temperature; pressing and forming the mixture by a roller; then, laying gridding cloth onto the surface of the bottom surface of a forming plate; obtaining a heat insulation plate semi-finished product; performing primary cutting on the heat insulation plate semi-finished product; after the natural curing, performing secondary cutting; obtaining a heat insulation plate finished product. The produced heat insulation plate has the advantages of good fireproof and flame retardant performance and high intensity toughness.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a production process of an inorganic modified polystyrene particle non-combustible thermal insulation board. Background technique [0002] Polystyrene insulation board is made of polystyrene resin supplemented by polymer, while heating and mixing, injection of catalyst, and then extruded to produce continuous closed-cell foaming rigid new environmental protection and energy-saving foam plastic board. Its interior is an independent airtight The air bubble structure is a high-quality heat insulation and thermal insulation material commonly used in the construction industry. [0003] Polystyrene insulation board has excellent thermal insulation performance. It is mainly made of polystyrene, and polystyrene is an excellent low thermal conductivity material. It is supplemented by extrusion to form a compact honeycomb structure. Thus effectively preventing heat conduction, the polyst...
