Abstract

The invention relates to a high-flame retardation and high-strength polyurethane heat insulation coat and a production method thereof. The problems of low flame retardation property, low strength, poor heat insulation property and slow construction of polyurethane heat insulation coats in the prior art are mainly solved in the invention. The high-flame retardation and high-strength polyurethane heat insulation coat sequentially comprises a polyurethane foaming layer (1), a fully-covered or locally-covered steel wire mesh or glass fiber material (2), a polyurethane foaming layer (3) and a glass steel, metal plate material or flame retardation engineering plastic protection layer (4) from inside to outside, wherein the protection layer is arranged on the external surface of a protected object. The coat and the production method thereof well solve the problems, and can be used in industrial construction of tanks or pipelines.

Description

High fire-retardance high-strength polyurethane insulation coat and preparation method thereof
Technical field
The invention belongs to a kind of urethane insulation coat and preparation method thereof, especially with regard to a kind of poly- ammonia of high fire-retardance high intensity Ester insulation coat and preparation method thereof.
Background technology
Heat-insulating and fire-proof energy-saving material is most important for some places and equipment, especially high to heat-insulating and fire-proof requirement Place and equipment such as freezer, refrigerator, natural gas transportation tank body, pipeline etc., therefore the selection of heat-insulating fireproof material is most important. Because polyurethane has the incomparable heat-insulating property of other materials, roof, wall, the smallpox of building are had been widely used for The key building such as plate, floor, insulation of door and window position, its demand is presented the trend of rapid growth.With some places Or the raising that equipment is required heat-insulating and fire-proof, simple polyurethane can not meet the demand of heat-insulating and fire-proof high intensity, it is necessary to right Polyurethane heat-insulation fire proofing re-optimization or design form a kind of high fire-retardance high-strength polyurethane insulation coat.
The coat of existing tank body or pipeline prepares first spraying polyurethane foaming layer, is then sprayed outside polyurethane foaming layer Polyurea layer is applied, then is cut with iron sheet and is coated on outside polyurea layer.Its poor flame retardant properties, low intensity, heat insulating ability are poor, construction is slow.
A kind of Chinese flame-retardant high-strength insulation polyureas coat of patent CN103863714B offers, including polyurethane foaming layer, First polyurea layer, steel wire and the second polyurea layer, its polyurethane coating material are made up of polyalcohol and isocyanates mixing, at it The excellent fire resistance of polyurethane coating material, high intensity cannot be realized under experiment condition, it is impossible to provide excellent heat-insulating property, Construction is slow.
Chinese patent CN104452987A provides a kind of improved compound polyurethane thermal insulation board, it include from outside to inside according to First overcoat of secondary tight bond, the first layer of polyurethane, aerogel layer, the second layer of polyurethane, the second overcoat, overcoat is Fiberglass, aluminium alloy, magnesium alloy, ABS engineering plastics, HDPE plastic, PC plastics or FRP plastics, gel layer are silicon systems aeroge Layer, the first layer of polyurethane thickness is 2~80mm, and the second layer of polyurethane thickness is 2~80mm.But under the conditions of its experiment Its poor flame retardant properties, low intensity, poor thermal insulation property, construction are slow.
