Abstract
The utility model relates to an improvement for the external application heat insulation thermal insulation material such as thermal pipelines or containers, which is characterized in comprising the composition of an inner insulation layer and an outer insulation layer. The inner insulation layer comprises at least one layer of rock wool, slag wool, or aluminosilicate fiber. The insulation outer layer is made of glass fiber. The utility model makes full use of the advantages of the two materials, enables the complement of each other, and improves the comprehensive performance of the insulation products greatly.
Description
Model utility is about the improvement to external application heat preserving and insulating materials such as heat distribution pipeline or containers.
The thermal insulation of external application such as heat distribution pipeline or container insulation or refrigerant pipe adopts individual layer rock wool, mineral wool, aluminum silicate fiber or glass fibre to make thermal insulation pipe or warming plate usually.Yet the individual layer thermal insulating material can not reach desirable heat insulation effect because of its inherent defect.For example aluminum silicate fiber, rock wool, mineral wool, they not only have excitant to skin, and thermal conductivity and unit weight are higher relatively, and water-proof performance is poor, easily moisture absorption deliquescing, not anti-storage, intensity is low after the moulding, consumptive material is many, and thermal insulation property descends greatlyyer in wet environment, thereby thermal loss is big; The glass fibre temperature tolerance is poor, generally can only be used for heat distribution pipeline or vessel insulation about 100 ℃, can not use for higher temperature more than 100 ℃.
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, provides a kind of improved cheap, applied widely, product strength height, good heat insulating, the compound insulating material of high comprehensive performance.
The model utility purpose realizes that basic design is the pluses and minuses complementation that makes thermal insulating material, forms novel using in hot environment, and the product strength height, the compound insulating material of good heat insulating.Specifically, the model utility compound insulating material is characterized in that having insulation internal layer and insulation skin to be composited, and said insulation internal layer has at least one deck rock wool, mineral wool or aluminum silicate fiber to form, and said insulation skin is a glass fibre.Model utility insulation internal layer can be selected rock wool, mineral wool or aluminum silicate fiber according to different serviceability temperatures, or its compound body.Thermal insulator can adopt rock wool or mineral wool to make internal layer below 300 ℃, thermal insulator can adopt aluminum silicate fiber more than 300 ℃.Insulation layer thickness is decided according to serviceability temperature, is generally 4-20cm.The thermal insulator temperature is low can to adopt single internal layer structure, and the thermal insulator temperature is higher should to adopt two internal layers.The spun-glass insulation outer layer thickness is excellent with the 15-40% of total thickness, is preferably 20-30%.The said glass fibre of model utility comprises centrifugal glass fibre and ultra-fine fibre glass.
Description below in conjunction with several indefiniteness embodiments further specifies model utility.
Fig. 1 is a composite structure thermal insulation pipe cross section structure schematic representation.
Fig. 2 is the tabular insulation block structural representation of composite structure.
Embodiment 1: referring to Fig. 1, be example with 300 ℃ of thermal insulator temperature, be rolled into earlier the insulation internal layer 1 of wall thickness 12cm with rock wool, through 220 ℃ of solidifying and setting 1 hour, and then cladding 2cm glass fibre 2, through 140 ℃ of solidifying and setting 40 minutes.
Embodiment 2: being rolled into wall thickness with aluminum silicate fiber is 5cm insulation internal layer, through 250 ℃ of solidifying and setting 1 hour, solidifies 40 minutes at 150-160 ℃ after cladding the 1.5cm glass fibre again.
Embodiment 3: be rolled into the insulation internal layer of wall thickness 4cm with alumina silicate, after 250 ℃ of solidifying and setting, clad 4cm mineral wool or rock wool again, after 180 ℃ of solidifying and setting, clad the 2cm glass fibre again, through 135 ℃ of solidifying and setting.
Embodiment 4: referring to Fig. 2, is example, piles the warming plate 3 of thick 14cm with aluminium silicate fiber with 500 ℃ of thermal insulator temperature, and after the heat cure typing, again coated with the glass fibre 4 of 6cm, the heat cure typing.
Model utility is owing to adopt resistant to elevated temperatures rock wool, mineral wool or aluminum silicate fiber thermal insulating material to make internal layer, outer compound cheap, thermal conductivity is low, nonhygroscopic glass fibre is done outer, made full use of two kinds of materials advantage separately, and the while has overcome the shortcoming of two kinds of materials, makes it complementary, thereby makes the heat insulating products performance improve greatly.Not only overall thermal conductivity is low than prior art, and good heat insulating can be used for the insulation of all temps, and water-proof performance is good non-hygroscopic, storge quality is good, and rigidity and structural strength height are stood repeatedly and moved, and it is low that next has unit weight, beautiful shape, lossless cost is low, and construction coats convenient.That model utility can be made into is tabular, tubulose, band shape or watt shape, is used for various high temperature heat distribution pipelines or container external application insulation, can make somebody a mere figurehead and lay, and is fit to direct-burried or trench laying again, equally also is suitable for the engineering thermal insulation of refrigerant pipe.
Said glass fibre of model utility or glass wool are synonym.
