Abstract

The invention relates to a halogen-free, barrier-forming fire retardant coating and to the use thereof, characterized in that the fire retardant coating comprises at least one terpene- and / or polyterpene-based film-forming binder.

Description

Background technique [0001] Fire-resistant coatings capable of forming a barrier layer are also called intumescent coatings, which are characterized in that they foam under the action of the corresponding temperature in the event of a fire and prevent, or at least temporarily block, the access to the ceiling by this foaming of the aforementioned fire-resistant coating. , heat penetration on steel structures, walls, cables, pipes and other materials. [0002] US-A-49652961 describes a flame retardant material consisting of a flame retardant coating material and an electrically conductive material. The flame-retardant coating material here consists of effervescent and char-forming substances, gas-generating compounds, film-forming binders, corresponding solvents and optionally further constituents. [0003] US-A-4879320 claims a flame retardant composition similar to that described in US-A-49652961, however instead of the conductive material a ceramic fiber material is added. ...
