Description
GLAZING SPACER BAR
This invention relates to a novel spacer for use in a sealed multiple glazed unit, particularly a doubk glazed unit.
Although the invention will be described in terms of a double glazed unit, it could also be used for multiple glazed ILnits e.g. triple glazed ILnits.
Known double glazed units typically consist of two glazing panes. usually of glass, which are sealed to and separated by a self-supporting spacer, usually of bar of metal or a plastics extrusion, around the outer edges of the glazing panes. The spacer bar may be hollow and may be formed into any shape by bending and/or by joining (e.g. using corner keys) as is well known in the industry. The spacer bar is sandwiched and sealed between the two glazing panes to form a unit, defining a cavity (interspace) between the glazing panes. The sealing against the glazing panes may be by way of a sealant and/or adhesive e.g. butyl rubber, pohzsuphide or poyuretliane. again as is known in the industry. In order to improve the heat insulation performance of the glazed unit, it is desirable although not essential to introduce an inert gas such as argon and/or xenon or similar gas into the cavity, in which case if the spacer bar is not constructed of 100% metal it is usual to have a composite hollow spacer bar with a gas barrier of metal tape (e.g. of steel or aluminium) around its outer edge i.e. facing away from the cavity (interspace). However the prcscnt invention provides for grcatcr heat insulation still. In addition, a thermoplastic spacer bar eliminates the problem of static electricity build-tip. This probkm is weH known in the industry. When a conventional metal spacer bar is substituted for an energy efficient polymer spacer bar, there is static electricity build-up because of the non-metallic spacer bar material. The static build-up may reduce moisture absorption capacity of the scaled unit, the said spacer system provides solution to this problem.
The present invention rdates to a spacer bar for a multiple glazed unit in which the spacer bar has a body having one or more cavities, wherein the body comprises a thermoplastic polymer and a blowing/foaming agent.
In one embodiment, the spacer bar body is hollow.
Presence of a foamed structure in the spacer bar body reduces the thermal conductivity of the spacer bar, The reduction in therma' conductivity can be significant, for example up to 40% when compared with a non-foamed spacer bar, S The spacer bar body may be porous.
The spacer bar body may be formed of a thermoplastic polymer comprising polypropylene (PP), polyethylene (PB). polycarbonate (PC). polvamidc (PA) commonly known as Nylon, polyvinyl chloride (PVC). p&ystyrene (PS) and or styrenic polymers and co-polymers, or any combination thereof In one embodiment thc thermoplastic polymer comprises or is polypropylene (PP).
The Mowing/foaming agent may be endothermic or exothermic, Thc blowing/foaming agent may comprise 4. 4'-Oxybis-bcnzencsulfonylhydrazidc (OBSH), azodicarbonaniide (ADA). bicarbonates or biurets.
In one embodiment, the spacer bar body may comprise a desiccant, The desiccant may be in the form of a powder. The desiccant may comprise an aluminosilicate, silica geL calcium su'phate, a montmoriflonite clay, calcium chloride, molecular sieve dcsiccants. activated charcoal or combinations thereof The desiccant may be a or 4A desiccant, Presence of a desiccant in the spacer bar body aids in absorbing moisture inside a glazing unit when the spacer bar is in usc in a glazing unit and increases the lifetime of the product. The presence of desiccant in the spacer bar body may also save time and energy of a sealed unit manufacturer by reducing the amount of desiccant which may need to be inserted into any cavity within the spacer bar.
One or more of the cavities of the spacer bar body may contain desiccant. The desiccant may be 3A or 4A desiccant beads.
In one embodiment, the spacer bar body further comprises a reinforcing material. The reinforcing material may be ally suitable material, for example chopped g'ass fibres, milled glass fibres, glass beads, glass bubbles, polymer fibres, ceramic fibres and natural fibres or any combination thereof, The proportion of reinforcing material S within the spacer bar body may be in a range from S to 50% by weight or more preferably from 25 to 50% by weight. Reinforcing material is addcd to improve the mechanical strength/stiffness, dimensional stability and thermal resistance.
In one embodiment, the spacer bar body may further comprise a coupling agent in combination with the reinforcing material. The coupling agent may be polypropylene functionalised with maleic anhydride or SCONA TPPP 9112, The spacer bar body may further comprise one or more pigment masterbatches. Each pigment masterbatch may comprise polypropylene (PP), polyethylene (PE), polyamide (PA), ethylene vinyl acetate, ethylene copolymers or other polymer and or copolymers.
The ability to include a pigment masterbatch allows sealed unit manufacturers to match the colour of the spacer bar to the glazing system.
The spacer bar body may comprise a UV stabibser, The UV stabfliser may be Tinuvin 213. Presence of UV stabiliser eliminates the problem of Li V/thermal degradation and or cracking as well as colour change during the work life.
The spacer bar body may comprise a thermoplastic polymer content in range of 10 to 80%, a reinforcing filler content in range of S to 60%, a moisture absorbing desiccant powder in range of 10 to 70%, a foaming agent in range of 0.1 to 7%. a UV stabiliser in range of 0.1 to 5%, an anti-static agent/additive in range of 0.1 to 5%, a coupling agent in range of 0,1 to 3% and a pigment masterbatch in range of 0.1 to 10%.
The spacer bar body of the present invention may be backed or coated with a moisture, moisture vapour and/or gas barrier. The moisture, moisture vapour and/or gas barrier may be metalized polymeric, poh'ester, muftdayered polyethvene or a nietalhsed polyester film/tape. The barrier may be a fUm/tape with a thickness that is in the range of ito 1000 microns.
The spacer bar may be vacuum sealed in a suitable metahzed polymeric packaging and boxed for storage.
S The spacer bar body may be elongate. The spacer bar body may be self-supporting.
The spacer bar body may have a thermal conductivity iii the range of 0.11 to 0.18, preferably in a range of 0.12 to 0.16 W/(m.K).
The spacer bar body may have a continuous cross section. The cross section of the spacer bar body may alternatively be provided with apertures and/or breaks around or in its perimeter, which may extend along all or part of its length.
