Patent ID: 8002136

Claim:
An explosion-proof material comprising a high-porosity sheet ( 11 ), said high-porosity sheet ( 11 ) being rolled up into a multilayer material body ( 1 ) with one side edge ( 12 ) of said high-porosity sheet ( 11 ) as an axis, and along a direction perpendicular to this side edge ( 12 ), characterized in that a skeleton( 13 ) is inserted in the gaps between any two layers of the multilayer material body ( 1 ) to fix and support the material body ( 1 ), wherein said skeleton ( 13 ) is at least one of formed by interweaving a carriage ( 131 ) and a stiffening ring ( 132 ), the stiffening ring ( 132 ) being located in the middle of the carriage ( 131 ) and fixed on it, the shape of the skeleton( 13 ) corresponding to the shape of material body ( 1 ); composed of columns( 133 ) and beam( 134 ), said columns( 133 ) are inserted between the high-porosity sheet ( 11 ) of the material body ( 1 ) and project on the upper and lower end surfaces of the material body( 1 ), and the beam( 134 ) is connected with the projection parts of columns( 133 ) on the upper and lower end surfaces of material body ( 1 ); composed of more than one framework( 135 ), these frameworks( 135 ) setting up between the multilayer high-porosity sheet ( 11 ) of the material body( 1 ), and the multiple frameworks( 135 ) connecting at their top and bottom; and composed of two parts, the upper skeleton and the lower skeleton( 136 ), the upper and lower skeletons( 136 ) respectively including mutually connected end frames( 1361 ) and insertion frames( 1362 ), said end frames( 1361 ) respectively putting over the upper and lower end surfaces of the material body( 1 ), and said insertion frames( 1362 ) inserting in the gap between the multilayer high-porosity sheet ( 11 ) of the material body( 1 ), for the purpose of fixing and supporting.
