The waterproof and breathable block of glass wool
Technical field
The utility model relates to a kind of structure design category of block of glass wool, specifically, relates to a kind of structure design category of waterproof and breathable block of glass wool.
Background technology
Glass wool is with the melten glass fibrillatable, form the material of cotton shape, have do not fire, nontoxic, corrosion-resistant, the plurality of advantages such as unit weight is little, coefficient of thermal conductivity is low, chemical stability is strong, the insulation of generally acknowledging at present superior performance, heat insulation, damping material, but hydroscopicity and the water absorption rate of glass wool are larger, under dampness, the significantly decline of the heat insulation effect of glass wool, tensile strength, the safety of the energy-conservation and outer heat preservation system of impact building.Therefore, block of glass wool exists the water-proof breathable properties problem in the application of various cladding systems or curtain wall at present, usually way is to paste one deck aluminium-foil paper or plastic sheeting on the block of glass wool surface, this aluminium-foil paper or plastic sheeting do not possess water-proof breathable properties, in case moisture enters heat insulating material inside, the performance of glass wool and the durability of building structure will be had a strong impact on.
The utility model content
The purpose of this utility model provides a kind of waterproof and breathable block of glass wool, and what solve that block of glass wool exists in cladding system or curtain wall are used does not possess the water-proof breathable properties problem.
The waterproof and breathable block of glass wool of the utility model design forms (seeing Fig. 1) by glass wool (1), glass fabric (2) and waterproof ventilated membrane (3), be provided with one deck waterproof ventilated membrane (3) on glass wool (1) top layer, between waterproof ventilated membrane (3) layer, be provided with layer of glass cloth (2).
Described waterproof ventilated membrane (3) is to be made through film-forming process by the formulated waterproof and breathable agent of waterproofing agent of organosilicon, amino fire retardant, silane coupler, urea and phenolic resins.
The waterproof and breathable block of glass wool of the utility model design is owing to be provided with the middle waterproof ventilated membrane that glass fabric is arranged of one deck on the glass wool top layer, make outside moisture be difficult to enter into heat insulating material inside, space enclosing structure and inner damp vapour are discharged, thereby what solve that block of glass wool exists in cladding system or curtain wall are used does not possess the water-proof breathable properties problem, and reach energy-conservation, improve the effect of building durability.
The waterproof and breathable block of glass wool of the utility model design is compared with the block of glass wool that one deck aluminium-foil paper or plastic sheeting are pasted in the surface, has following advantage:
1. have excellent water proofing property, its water resistance greater than the water column effect 4h of 100cm after test leakproof behind.
2. have preferably gas permeability, its water vapour permeability can reach 1500g/m
224h.
3. this block of glass wool is owing to have water-proof breathable properties, and coefficient of thermal conductivity is lower, obtains its application life prolonging.
Description of drawings
The structural representation of the waterproof and breathable block of glass wool that accompanying drawing 1 designs for the utility model.
Among the figure: the 1-glass wool; The 2-glass fabric; The 3-waterproof ventilated membrane.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the waterproof and breathable block of glass wool is comprised of glass wool (1), glass fabric (2) and waterproof ventilated membrane (3), wherein, glass wool (1) single face top layer is provided with one deck waterproof ventilated membrane (3), is provided with layer of glass cloth (2) in the middle of waterproof ventilated membrane (3) layer.
When the waterproof and breathable block of glass wool is used for curtain wall construction, the one side that is provided with waterproof ventilated membrane is arranged on the outside, another side then is bonded on the base course wall.
