Fire protection glazing, method of making same and materiał used in this method |
摘要 |
A glazing assembly for protecting against fire exhibits at least two panes adhesively bonded together via a spacer and a water-comprising intermediate layer which fills the intermediate space between the panes. The spacer is composed of a string, applied by extrusion over the peripheral region of a pane, made of a butyl polymer obtained from 40 to 65% by weight of polyisobutylene, from 10 to 25% by weight of carbon black and from 10 to 40% by weight of filler. Within these ranges, the composition is chosen so that the butyl polymer exhibits, at a temperature of 80° C., a transverse or shear modulus of elasticity of G* of 1.2 to 2.2 MPa. |
