Embodiment 1
[0042] 1kg of epoxy resin is made into aqueous dispersion, 7kg of cellulose xanthate is dissolved in aqueous sodium hydroxide solution, and the two are mixed to form a liquid adhesive with a concentration of 70wt%.
[0043] Provide PET non-woven fabric 15kg, area density 35g / cm 2 , Porosity 85%. Provide two layers of aramid 1313 fiber textile layers with the same thickness, the total weight is 70kg, and the area density of each aramid fiber textile layer is 65g / cm 2 , Aramid fiber linear density 44tex.
[0044] Two layers of aramid fiber textile layer sandwich the PET non-woven layer to form a superimposed base fabric.
[0045] Add m-xylylenediamine to the liquid adhesive, and then apply the liquid adhesive to the superimposed base fabric, and use a roller or brush to apply pressure to promote the penetration of the liquid adhesive from the aramid fiber textile layer on one side to the Aramid fiber textile layer on the other side. During the infiltration process, the molec...
Embodiment 2
[0049] 1kg of epoxy resin is made into aqueous dispersion, 10kg of cellulose xanthate is dissolved in aqueous sodium hydroxide solution, and the two are mixed to form a liquid adhesive with a concentration of 65wt%.
[0050] Provide PET non-woven fabric 20kg, area density 23g / cm 2 , Porosity 85%. Provide two layers of aramid 1313 fiber textile layers with the same thickness, with a total weight of 70kg and an area density of 70g / cm 2 , Aramid fiber linear density 44tex.
[0051] Two layers of aramid fiber textile layer sandwich the PET non-woven layer to form a superimposed base fabric.
[0052] Add m-xylylenediamine to the liquid adhesive, and then apply the liquid adhesive to the superimposed base fabric, and use a roller or brush to apply pressure to promote the penetration of the liquid adhesive from the aramid fiber textile layer on one side to the Aramid fiber textile layer on the other side. During the infiltration process, the molecular chains of epoxy resin and ce...
Embodiment 3
[0056] 1kg of epoxy resin is made into aqueous dispersion, 12kg of cellulose xanthate is dissolved in aqueous sodium hydroxide solution, and the two are mixed to form a liquid adhesive with a concentration of 80wt%.
[0057] Provide PET non-woven fabric 20kg, area density 35g / cm 2 , Porosity 85%. Provide two layers of aramid 1313 fiber textile layers with the same thickness, with a total weight of 70kg and an area density of 80g / cm 2 , Aramid fiber linear density 44tex.
[0058] Two layers of aramid fiber textile layer sandwich the PET non-woven layer to form a superimposed base fabric.
[0059] Continue to pressurize to a pressure ≥ 1.5 atmospheres, maintain the pressure, add m-xylylenediamine to the liquid adhesive, and then apply the liquid adhesive to the superimposed base fabric, and apply pressure with a roller or brush to promote the liquid state. The adhesive penetrates from the aramid fiber textile layer on one side to the aramid fiber textile layer on the other si...
