1. it is liquid cement agitation is uniform；
2. by the glue after stirring according to the alkali-free of every square metre of 1400g even spread to 380 grammes per square metres without on wax glass felt；
3. the alkali-free of coated glue is successively added on corrosion resistant plate without wax glass felt, being often superimposed one layer will will be upper
Glass felt roll-in after glue strikes off；
4. the glass felt after roll-in is struck off is put into drying room, and 45 degrees Celsius dry 24 hours, obtain heat foamable glass felt plate
Blank；
5. heat foamable glass felt plate blank is put into into normal temperature high voltage on hydraulic press to suppress 30 minutes；
6. the heat foamable glass felt plate blank after compacting is put into into again 45 degrees Celsius of drying 2-6 hours of drying room；
7. burr are cut off, polybag damp-prrof packing is obtained final product.
Beneficial effect：The present invention by high-temperature foaming agent cause material itself by heat foamable produce thickness on expanding, 130
After degrees Centigrade 1 hour, the heat foamable glass felt plate thickness foaming and intumescing to the 200%～250% of original thickness, expansion rate
Significantly larger than common thermal expansion glass mat；And the heat foamable glass felt plate foaming solidify afterwards are shaped, the rigidity for becoming hard is swollen
Swollen body, thickness will not bounce back, and present without rigid loose shape after thermal expansion glass mat expanded by heating common at present.
