Abstract
The utility model provides an insulation material with a composite layer structure, which relates to a novel insulation material and is especially suitable for the insulation of a high temperature body. The utility model is characterized in that the inner layer of the insulation material is made by adopting the composite form of the mineral wool and the polyurethane materials, the outer layer of the insulation material is a polyurethane foam tile (board), an air layer is formed between the inner and the outer layers, and the inner and the outer surfaces of the outer layer are sprayed with mercury to form a heat counter radiation layer. The insulation material integrates the advantages of two materials of the mineral wool and the polyurethane, and a heat transmission method is blocked effectively. The insulation material can be used widely for the insulation work of chemical industries, buildings, process pipelines, mines, cold storages, refrigerators and oil fields.
Description
The utility model belongs to a kind of insulation material of new structure, particularly a kind of insulation material that is used for high-temperature body.
The existing material category that is used for the insulation aspect is more, and common have insulation materials such as rock wool, perlite, felt, mineral wool, polyurethane foam plastics, can obtain certain heat insulation effect though use these materials, and they all exist not enough aspect.For example rock wool is mingled with many glass fibres, influences workmen's health during construction; Perlite thickness and weight are bigger, and cracking infiltration easily, reduce heat insulation effect; Mineral wool department wet at water and the grease seepage can not use; Though polyurethane foam is than above-mentioned different materials advanced person, it is not easy to the insulation to high-temperature body, when insulation body surface temperature surpasses 120 ℃, will produce aging, metaboly, has shortened the insulation cycle and this material heat insulating work expense is higher.Patent documentation since in 1985 by retrieval, find the patent No. 88210316, name is called the utility model patent of " sandwich construction heat insulation tile ", this watt adopts the linear pad of the horizontal adding of corrugated paper and the bonding back of thin aluminium foil to roll and forms, because the space between space between the corrugated paper corrugation and layer and the layer, has very little thermal conductivity factor, add the anti-heat radiation effect of thin aluminium foil, thereby having intercepted heat effectively scatters and disappears, can obtain comparatively desirable heat insulation effect, yet though because corrugated paper belongs to fibrous material in advance through steeping colored alkali immersion treatment, under hot environment, toast for a long time, the cellulosic carbonization phenomenon will occur, be not easy to insulation high-temperature body.In addition, because the button of this kind heat insulation tile seam and the joint sealing between forward and backward watt are not tight, cause heat to scatter and disappear easily.Again on the one hand, because the aluminium foil price is comparatively expensive, strengthened the cost of heat insulating work.
The purpose of this utility model just provides a kind of insulation material of lamination layer structure, it overcome " sandwich construction heat insulation tile " be difficult for be applied to high-temperature body insulation, bad sealing and with the high deficiency of aluminium foil cost, and than other insulation material have high insulating effect, cost is low, intensity is high, service time is long, in light weight, water imbibition is little, the advantage of easy operating.
The technical solution of the utility model is achieved in that
Be compounded to form inner layer material with mineral wool and polyurethane material; Form cladding material at the inside and outside surface spraying of polyurethane foamed material mercury; Inside and outside layer material overlaps, intussusception, and the mode by embedding mutually end to end, perhaps relies on the outer surface fin of inner layer material to make between the inside and outside layer and forms air layer; At outer field surrounded external protection.When carrying out pipe insulation with this material, the inside and outside layer of each joint tube is formed by two semi-cylindrical shaped watt make-ups respectively, and the button seam do not coincide, and is that afterbody that head by back one joint tube embeds last joint tube connects and forms between every joint tube; Wherein two straight flanges of internal layer watt have fin or groove, form the connecting mode of mutual insertion during make-up.When this material was used for plane or special-shaped vessel insulation, the air layer between the inside and outside layer was by attached to the fin on the inner layer outer surface at interval.
The utility model is compared with existing insulation material, particularly compares with " sandwich construction heat insulation tile ", has following advantage and good effect.
The first, be applicable to insulation and high insulating effect to high-temperature body.Because the internal layer of this material adopts the composite construction form of mineral wool and polyurethane foam, thereby combine the advantage of these two kinds of materials, overcome the shortcoming of simple polyurethane foam or cellulosic corrugated paper non-refractory simultaneously.
The second, sealing is tight.Particularly when this material is applied to pipe insulation, because the head of every joint tube embeds the afterbody of last joint tube, and two straight flanges of internal layer watt have fin or groove, form mutual plug-in type connecting mode during two slices watts of make-ups, guaranteed the strictness sealing between joint and the joint, heat scatters and disappears few.In addition, have certain angle at interval because inside and outside layer watt button is sewn on the space, it is few to have guaranteed that also button seam place heat scatters and disappears.
The 3rd, compare with " sandwich construction heat insulation tile ", the utlity model has advantage with low cost.Introduction had been done in the front, and " sandwich construction heat insulation tile " is to be bonded by aluminium foil and corrugated paper, and the aluminium foil price is more expensive, and be difficult for corrugated paper bonding, fragmentation easily when rolling.The utility model adopts the method at inside and outside laminar surface spraying mercury, has both played the antiradiation effect to heat, has overcome the high shortcoming of cost again.
The 4th, the utility model has also that manufacture technology is simple, and installation is easy to maintenance, and is free from environmental pollution, and capacity is less, and thermal conductivity factor is low, the intensity height, and good flame resistance, durability is long, and water imbibition is little, antidetonation, anticorrosive, remarkable advantages such as sound insulation.
The utility model lamination layer structure insulation material, its heat preservation principle is such:
The mineral wool of internal layer and the thermal conductivity factor of polyurethane foam are little, and wherein are mingled with many minor air cells, and the air layer of adding between the inside and outside layer all has less thermal conductivity factor, has intercepted hot conductive process.Owing to adopt strict seal means to intercept the convection of heat process.Because the mercury spraying method is adopted on outer inside and outside surface, has formed hot antiradiation system.In a word, the structure of this material has intercepted three kinds of transfer modes of heat fully and effectively, thereby can obtain heat insulation effect well.
