Description
Technical field
The utility model relates to a kind of composite panel.
Background technique
Along with glass reinforced plastic composite board widely using in automobile and other industries, the performance of glass reinforced plastic composite board also needs to improve constantly.The effect of heat insulation of current refrigerator car to compartment board has high requirements, and traditional glass reinforced plastic composite board effect of heat insulation has much room for improvement, and manufacturing process is to be improved.About the problem of refrigeration carriage board, the thermal conductivity of current polyurethane foam is 0.023w/ (m
2* k), compare with XPS, extruded sheet, expansion polyphenyl plate, phenolic foam board, rock cotton board etc., polyurethane foam board is that in current all thermal insulating materials, thermal conductivity is minimum, but this material is high molecular polymer, belong to very easily comburant, can not store in hot environment or use, and difficulty produces flat smooth effect.
Application publication number is that the Chinese patent of CN102700628A discloses a kind of glass fibre reinforced plastics skeletal structure foaming refrigerator car insulation railway carriage or compartment plate, this insulation railway carriage or compartment plate comprises inside panel, exterior skin, railway carriage or compartment framework, railway carriage or compartment framework is between inside panel and exterior skin, the inner side surface of exterior skin is provided with glue-line, railway carriage or compartment framework comprises core and is wrapped in the frp layer of core appearance, be provided with cavity in the middle of the framework of railway carriage or compartment, in cavity, be filled with polyurethane foam contoured foam; Near inside panel or exterior skin place is unsettled is fixed with layer of glass grid cloth in cavity, between fiberglass gridding cloth and inside panel or exterior skin, be provided with spacing.This insulation railway carriage or compartment plate adopts glass fibre reinforced plastic integral skeleton, has the advantages that intensity is high, lightweight, water-proof performance is good, however most of glass fibre reinforced plastics to the relative density of water between 1.4 ~ 2.1, be that the railway carriage or compartment plate of skeleton still has room for promotion in weight with glass fibre reinforced plastics.
Aerogel is a kind of solid matter form, the solid that density is minimum in the world, and thermal insulation property is fabulous, if can be applied in compartment board, will bring good result.But about aerogel products, the gentle gel felt of airsetting rubber powder is not suitable for the interlayer doing compartment board, therefore needs to find a kind of suitable aerogel material, and uses suitable technique to use it for manufacture composite sheet.
Model utility content
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is: provide a kind of lightweight, ultralow heat conduction once-through composite panel that intensity is high, stable.
For solving the problem, the technological scheme that the utility model is taked is as follows:
A kind of ultralow heat-conductive composite material plate, comprises surperficial sticky, the first composite felt, the second composite felt, aerogel heat-insulating plate, water conservancy diversion composite felt; Described surface is sticky, the first composite felt, the second composite felt, aerogel heat-insulating plate, water conservancy diversion composite felt are laid successively; The first described composite felt is common composite felt; The second described composite felt is the composite felt with guide functions.
Further, the material of main part of described aerogel heat-insulating plate is aerosil.
Further, the thickness of described aerogel heat-insulating plate is 10 ~ 40cm.
The beneficial effects of the utility model
1. more most of material is compared, aerogel heat-insulating plate density low ， that the utility model uses Wei≤250kg/m
3, the hot Xi Shuo≤0.019w/(m of Dao
2* k), there is high-strength light, the feature that effect of heat insulation is good.Comparatively polyurethane material is compared, and aerogel heat-insulating plate burning-point is high, flatness is high, can improve product surface smoothness.
Accompanying drawing explanation
Fig. 1 is ply angles schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model content is described in further detail.
As shown in Figure 1, a kind of ultralow heat-conductive composite material plate, comprises surface sticky 11, first composite felt 12, second composite felt 13, aerogel heat-insulating plate 14, water conservancy diversion composite felt 15.Sticky 11, first composite felt 12, second composite felt 13 in surface, aerogel heat-insulating plate 14, water conservancy diversion composite felt 15 are laid successively.First composite felt 12 is common composite felt.Second composite felt 13 is for having the composite felt of guide functions.Further preferably, for selecting suitable material, for reaching better lightweight, effect of heat insulation, the material of main part of the aerogel heat-insulating plate 14 in the utility model is aerosil.Further preferably, the thickness of aerogel heat-insulating plate 14 is 10 ~ 40cm, and the thickness of the preferred aerogel heat-insulating plate 14 of the utility model is 25cm.
The hot Xi Shuo≤0.019w/(m of aerogel heat-insulating plate Dao that the utility model uses
2* k), not only intensity meets compartment board requirement, can also reduce the thickness of interlayer, and use aerogel heat-insulating plate material to be about 60cm as the compartment board thickness of sandwich of layers, as calculated, the thickness that the utility model makes compartment board can reduce 13mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
