Abstract
The present invention provides a synthetic resin composition from which a combustion residue produced by combustion is rigid. The synthetic resin composition of the present invention is configured such that the strength of the combustion residue of the composition after combustion in an atmosphere of 800° C. for 20 minutes is 0.5 N/mm2 or more. Thus, the combustion residue produced by combustion is very rigid. The combustion residue is capable of reliably holding a state where a joint part is filled therewith and clogged even during a fire, preventing flames from passing through a sealing part such as the joint part, and imparting excellent fire-proof performance to a wall part of a building construction.
Claims13
A synthetic resin composition comprising a synthetic resin, a mineral having a Mohs hardness of 5 or more, and a binder component, a strength of a combustion residue of the synthetic resin composition after combustion in an atmosphere of 800° C. for 20 minutes being 2.0 N/mm2 or more,
- wherein the binder component contains at least one compound selected from the group consisting of glass frit and a boric acid compound, and
- wherein a content of the mineral in the synthetic resin composition is 50 parts by mass or more relative to 100 parts by mass of the synthetic resin.
