Abstract
A permanently plastic Plasticine for fire-protection applications is described, comprising a matrix composition, which contains fire-protection additives and conventional auxiliary materials and is based on organic polymers, and a method for its preparation and its use for the fire-protecting sealing of openings, cable and pipe bushings in walls, floors and/or ceilings, of joints between ceiling parts and wall parts, between masonry openings and construction parts, which are to be installed, such as window frames and door frames, between ceilings and walls and between exterior walls and curtaining facades, for the purpose of thermal insulation and/or fire protection, are described.

Permanently plastic Plasticine for fire-protection applications, comprising a matrix composition based on organic polymers and containing a fire-protection additive and conventional auxiliary materials, characterized in that the matrix composition represents a mixture of an aqueous polymer dispersion (A) and a low-molecular weight, permanently plastic, liquid polymer (B) in a ratio by weight of (A) to (B) of 6:1 to 1:2.5.
Method for the preparation of the Plasticine, comprising a matrix composition based on organic polymers and containing a fire-protection additive and conventional auxiliary materials, characterized in that the matrix composition represents a mixture of an aqueous polymer dispersion (A) and a low-molecular weight, permanently plastic, liquid polymer (B) in a ratio by weight of (A) to (B) of 6:1 to 1:2.5, characterized in that a) a homogeneous mixture of the aqueous polymer dispersion (A), water and optionally one or more stabilizers (E) is formed,
- b) the mixture is adjusted to a pH ranging from 8 to 9,
- c) the low molecular weight, permanently plastic, liquid polymer (B) is mixed in,
- d) optionally pigments (F), fillers (G) and optionally additives with ceramizing activity (1), ablative activity (C2) and/or flame-inhibiting activity (C4) are incorporated and homogenized,
- e) optionally the intumescing additive (C3) is added, at least one of the fire-protection additives C1 to C4 being incorporated, and the mixture is homogenized, optionally extruded and optionally dried.
