Abstract
The utility model discloses a heat insulating sandwich plate which belongs to construction material. The heat insulating sandwich plate comprises a heat insulating layer, an upper metal substrate and a lower metal substrate which are tightly clung to the upside and the downside of the heat insulating layer. The outer surface of the upper metal substrate is coated from the inside to the outside with an anticorrosion coating and a weatherproofing polyester coating; and the outer surface of the lower metal substrate is coated with an anticorrosion coating; wherein, the anticorrosion coating is heavy-anticorrosion epoxy powder coating or zinc based epoxy powder coating, and the heat insulating layer is foaming material. The heat insulating sandwich plate has the advantages of anticorrosion, weatherproofing and heat insulating performance and can be applied to roofs and wall surfaces of steel-structure factory buildings and other heat insulating places.
Description
Technical field
The utility model relates to a kind of insulation sandwich board, belongs to building material technical field.
Background technology
Along with enlargement of cities, expanding economy, many enterprises, station, airport are with resettlement, enlarging and newly-built, and major part adopts steel building.Sandwiched plate is energy-conservation because of having, and coefficient of thermal conductivity is little, no heat bridge phenomenon; The construction environmental protection, pollution-free, clean easily; Speed of application is fast, is easy to mechanized construction; Endurance quality is superior, is out of shape the advantage of little, corrosion-resistant and chemical resistance of concrete and is widely adopted.
At present, sandwiched plate heat insulating material commonly used is polyurethane foam or rock wool, the anticorrosion waterproof of sandwiched plate two sides brushing paint.But the polyurethane foam cost is higher, has harmful isocyanates in foaming process, contaminated environment; The rock wool cost is low, but heat insulation effect is poor, in the wet environment unstable properties, seldom adopts at aspects such as freezer, dwelling house, hospitals.And sandwich board surface adopts oil paint coating to carry out anticorrosion waterproof, and contaminated environment wastes energy.
Summary of the invention
The purpose of this utility model is the above-mentioned defective that overcomes prior art, and a kind of insulation sandwich board is provided, and it is moderate to have a cost, and heat-insulating property is better, and is pollution-free, the characteristics of energy-conserving and environment-protective.
The technical solution adopted in the utility model is: a kind of insulation sandwich board, it is characterized in that comprising insulation layer, fit tightly metal substrate and following metal substrate on the insulation layer two sides, be coated with successively from inside to outside at the external surface of last metal substrate corrosion-inhibiting coating and polyester weathering resistance coatings are housed; Be coated with at the following external surface of metal substrate corrosion-inhibiting coating is housed.
Corrosion-inhibiting coating thickness is 40-100 μ m.
The weather-proof coating layer thickness of polyester is 50～80 μ m.
Insulation layer is an expanded material, and insulation layer thickness is 10mm-100mm.
Metal substrate is steel plate or galvanized sheet.
The utility model has the advantages that: compared with the prior art, this product adopts the powdery paints coating, environmental protection, and moderate cost, high insulating effect is easy to suitability for industrialized production, and material source is extensive, has application promise in clinical practice.This warming plate can be widely used in the roofing and the metope of steel-structure factory building.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a section structure schematic diagram of the present utility model.
Among the figure: 1, polyester coatings, 2, corrosion-inhibiting coating, 3, metal substrate, 4, insulation layer, 5, metal substrate, 6, polyester coatings.
The specific embodiment
As shown in drawings, metal substrate 3 is a cold-rolled steel sheet.With cold-rolled steel sheet shaping, preliminary treatment, then with cold-reduced sheet 3 single faces spraying epoxy double antiseptic powder coating, deliver to 200 ℃ of curing oven heating 5min and solidify, become corrosion-inhibiting coating 2, thickness 40-60 μ m; With cold-reduced sheet 5 single faces spraying epoxy double antiseptic powder coating, deliver to 200 ℃ of curing oven heating 5min and solidify, become polyester weathering resistance coatings 6 thickness 60-100 μ m.Coating keeps flat downwards on the conveyer belt, enter foamed coating spray room, steel plate 3 sprays polyester powder coating while hot on anticorrosive coat, and this steel plate is sent into 200 ℃ of curing ovens again heat about 5min, become polyester weathering resistance coatings 1, thickness 50-80 μ m, afterwards with steel plate 3 coatings of application polyester coatings to overlying on the steel plate 5 that comes out in foamed coating spray room, two plates are sent into 200～220 ℃ curing oven heating make fully and solidify, foam, product.
