DEVELOPMENT OF METHODS FOR PRODUCING IMPROVED-QUALITY MINERAL WOOL INSULATION TILES AND BINDERS FOR PRODUCTION

摘要

In an effort to improve the quality and thermal insulation performance of mineral wool insulation, and to reduce the emission of formaldehyde from mineral wool tiles based on carbamide-formaldehyde, a new method has been developed for the production of a new carbamide-formaldehyde resin for the production of mineral wool tiles, by forming a mineral wool carpet from pulp. The resin is reported to contain 20 times less free formaldehyde, and is synthesised in three stages. A series of sand-resin bars were manufactured to model mineral wool tiles and to test properties such as strength, water resistance and formaldehyde emissions. Details are given of the production of a new-generation Timlak material which is claimed to correspond entirely to equivalent foreign thermal insulation.
