Flame-retardant high-temperature-resistant sheet material and producing method thereof

Abstract

The invention discloses a flame-retardant high-temperature-resistant sheet material which is characterized by being composed of following raw materials, by weight, 100 parts of foam phenolic resin, 5-8 parts of epoxy resin, 10-15 parts of a flame-retardant agent, 8-10 parts of polyurethane capped by oleyl alcohol, 8-10 parts of a paraffin emulsion, 8-10 parts of polyethylene glycol, 1-2 parts of glass fibers, 1-2 parts of a foam-homogenizing agent AK-8804, 3-5 parts of dichloride methane, 2-4 parts of an acidic curing agent, 1-2 parts of zinc oxide, 15-18 parts of fly ash, 0.5-0.7 parts of sodium silicate and 200-300 parts of water. The paraffin emulsion prepared from the polyurethane is very good in stability. With addition of the epoxy resin, compared with a pure phenolic foam material, the sheet material is improved in both compression strength and bending. The flame-retardant agent enables the foam to have an excellent burn-resistant and heat-insulating performance, thereby greatly increasing the service life of the sheet material; furthermore, the fly ash can further enhance the strength of the sheet material. The sheet material can be widely used in public and civil buildings and decorations and other fields and can be used for replacing other building and decorative materials.

Description

technical field [0001] The invention relates to a thermal insulation board and a production method thereof, in particular to a flame retardant and high temperature resistant board and a production method thereof. Background technique [0002] The shape of the plate product is flat, the ratio of width to thickness is large, and the surface area per unit volume is also large. This shape feature brings its characteristics in use: the surface area is large, so the ability to contain and cover is strong. It is used in chemical industry, containers, construction, metal products, and metal structures. It can be cut, bent, stamped, welded, and made into various product components. It is flexible and convenient to use, and occupies an extremely important position in the departments of automobile, aviation, shipbuilding and tractor manufacturing. It can be bent and welded into All kinds of structural parts such as section steel, steel pipe, large I-beam, channel steel and other compl...
