Abstract
The present invention relates to the method of using intumescence carriers which are reaction products of aluminum compounds, phosphorus-containing acids, boron-containing acids and alkanolamines and can optionally contain up to 36 mol of water per mol of aluminum compound employed for fireproof glasses.
Claims5
The method of fireproofing laminated glass constructions, which comprises filling or coating said laminated glass constructions with an intumescence carrier wherein said intumescence carrier is the reaction product of
- 1. 1 mol of an aluminum compound selected from the group consisting of aluminum oxides, aluminum-oxide hydrates, aluminum hydroxides, and aluminum carbonates, with
- 2. 2 to 5 mol of a phosphorous-containing acid selected from the group consisting of orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid, polyphosphoric acid, phosphonic acid, and phosphinic acid,
- 3. 2-9 mol of a boric acid, and
- 4. 2 to 9 mol of an alkanolamine.
