Wherein, borax soln concentration described in step b is 3-5%;Dilute sulfuric acid concentration described in step c is 40-50%.
The present invention reaction mechanism and have the beneficial effect that:
Under the catalytic action of dilute sulfuric acid, using polyvinyl alcohol, formaldehyde and expanded graphite as raw material, poly- second is obtained by fabricated in situ
Enol formal compound, then using glycerine and starch as pore-foaming agent, pentane be foaming agent, make polyvinyl alcohol contracting first by heating
Aldehyde compound, glycerine, starch and pentane mixture foam to obtain polyvinyl formal compound porous material, have processing
The adsorption capacity of waste water from dyestuff, by adding expanded graphite, the specific surface area of porous material is added, improves its adsorption capacity;
With polyvinyl alcohol (PVA) for adhesive, nonhazardous, but its poor water resistance is first modified with borax to polyvinyl alcohol, borax with
Reaction is crosslinked between polyvinyl alcohol, improves the water resistance of polyvinyl alcohol;It is sub- with oxidant hydrogen peroxide, catalyst sulfuric acid again
Iron, urea carry out oxidative degradation and hydrophobically modified to it, to reduce the viscosity of glue, improve its solid content and water resistance, are dredged
Water-based energy is got well and the PVA glues of good combination property, good to the hydrophobically modified effect of porous material.
