Definitions

  • the invention relates to techniques for manufacturing insulating glazing which include transparent plates assembled with a gasket plastic material.
  • this first bead also plays a temporary role, before the polymerization of the elastomer constituting the second barrier: it allows all the handling of the assembled glazing before the elastomer of the second bead can play its role without the deformations, in particular, the crushing of the first bead does not cause deviations in the tolerances of the insulating glass (overall thickness, sliding of one glass in relation to the other) which would be unacceptable.
  • the characteristics of the first cord are such that they guarantee good quality glazing as long as two conditions are met: the thickness of the blade gas between the plates remains limited (for example at most around 12 mm) and also, the polymerization of the elastomer of the second bead is performed at the place of manufacture, before packaging and shipping and in general, before it is possible to handle the assembly without pity. We want to be able to free our from these constraints without necessarily harm other qualities of the product.
  • the task of the invention is to provide a material which allows the production of insulating glazing with an internal gas space greater than 12 mm and preferably of the order of 16 or 18 mm or even more.
  • the invention provides a product intended to constitute the first cord insulating glass without metal interlayer, the second bead being produced by polymerization of an elastomer, its composition comprises in particular polyisobutylene and butyl rubber, and the weight proportion of butyl rubber is less than 6%, the composition comprising a polymer hot-melt in a weight proportion of 1.5 to 4%.
  • This polymer hot melt has a melting temperature range above 90 ° C and it essentially composed of copolymers based on ethylene, acrylic acid, derivatives of acrylic acid and ionomers.
  • the weight proportion of polyisobutylene is included between 40 and 70% with a polyisobutylene fraction of molecular weight less than 1000 between 10 and 20%.
  • the product of the invention comprises a weight proportion of colloidal silica included between 0 and 20%, carbon black from 10 to 40% and molecular sieve from 0 to 5%.
  • the invention also relates to the application of the product to the production insulating glazing whose plates are separated by spaces included between 11 and 20 mm and the production of insulating glazing which is packaged before polymerization of the elastomer constituting the second bead. Of preferably, this is carried out at room temperature.
  • the shapes of the parts of the beginning and the end of the first cord are complementary bevels, thinning one compensating for the thickening of the other.
  • the junction of the beginning and end of the first bead is performed on a straight edge of the glazing.
  • the conditions that must be respected concern the thickness of the gas slide and the conditions of polymerization of the bead in elastomer.
  • the latter usually consists of polysulfide.
  • the conditions for its polymerization are either rapid polymerization (of a duration of about an hour) in an oven where the temperature is around of 50 ° C or, for a much longer duration at temperature ordinary.
  • rapid polymerization of a duration of about an hour
  • oven and staff on the production lines to make it work. We want to be able to delete this step which loads the cost of the product. But on the other hand, we wish not to lengthen unnecessarily the duration of storage of the product on the production lines.
  • the solution would be to be able to immediately package the product, as soon as the coating of the polysulfide is finished.
  • the pressures and vibrations exerted on the product during manipulations to pack it in the box or on the easel then at the time loading and during transport and unloading are not bearable by the glazing, it deforms, undergoes variations in thickness, crushing in some places compensated by thickening in others, and sliding of one glass in relation to the other (or to the others).
  • it is essential to improve the mechanical performance of the product constituting the first bead.
  • a second elastomeric sealant (4) is deposited by coating, in the state pasty then gradually hardens. This sealant (4) seals the two glasses and protects the first sealant (3) against liquid water.
  • the innovation described below relates to an improvement of the first putty (3).
  • This composition has the advantage of allowing the manufacture of a 6 or 10 mm thick seal, very waterproof and sufficiently adherent to insulating glass panes.
  • Insulating glass without metal interlayer assembled with this composition very largely satisfy the requirements of standards and directives concerning the durability of insulating glass: in particular 56 day high humidity test at 55 ° C / 95% relative humidity and the test described in NF P 78-451 and in the UEATC directive of October 1985 for approval of insulating glass.
  • this sealant can be made from inexpensive and can be extruded and applied to glass at a temperature from 80 to 120 ° C and at high speed, up to 50 cm / s.
  • the first relates to the trend of elastomeric sealants of the second bead (4) to show a slight shrinkage which results in a thickness reduction of 0.1 to 0.2 mm.
  • the second is a function conditions for the polymerization of the elastomer.
  • the polymerization of some sealants can be significantly accelerated by temperature: for example, a polysulfide typically requires 6 hours to cure at 20 ° C and only 1 hour 30 in an oven at 50 ° C. But at 50 ° C the pressure increases in the blade air from the glazing which can cause some deformation of the first seal (3) in the upper part, the glazing being held vertically.
  • the inventors to solve the problem have thought of reducing substantially the amount of butyl rubber introduced into the composition. Whereas in the most common variant of the first bead putty this proportion was 10% they reduced it to 5% and even in one case to 2%.
  • PIB polyisobutylene
  • the butyl rubber used was a commercial composition consisting of a copolymer of isoprene and isobutylene in a proportion about 5-95%, GDP was also a trade product with molecular weights between 8,000 and 15,000 for solid GDP and 800 for the newly introduced liquid GDP, for the polymer hot melt, it was a copolymer composition based on ethylene, acrylic acid, derivatives of the same acid and ionomers.
  • sealant of the invention can obviously be used with any sealant which allows control of the extruded form.
  • the bevel itself is not essential. It suffices to have between the start and the end of the extrusion a space, a slot, sufficiently narrow and / or a putty sufficiently malleable and sticky so that at the time of pressing, the plugging of the slot is guaranteed.
  • FIG. 5 shows such an example without a bevel with the ends 11 and 12 of the adjacent convex cord 3 which have merged.
