The reaction of 3. major-minor solidifying agent (also claiming major-minor initiator, water and inorganic peroxy salt) and putty base-material:
Auxiliary initiator (inorganic peroxy salt) is only water-soluble like peroxidation sulfuric acid potassium, sodium, ammonium salt, is insoluble in organic solvent and the resin, prepares in the process at putty and adds auxiliary initiator in the main base-material (resin) of putty usually.
When construction, join main initiator water in the putty; Auxiliary initiator in the putty is met water can very fast dissolving and produce the main base-material (resin) that radical causes in the putty cross-linking polymerization takes place; And the auxiliary base-material generation hydration reaction (gel) in water and the putty produces Ca (OH) again in the hydration reaction process simultaneously
2Facilitate the auxiliary initiator in the putty further to decompose the generation radical so again; Main base-material and contained vinyl monomer and unsaturated polyester that these radicals quicken again to cause in the putty play polyaddition reaction; The auxiliary initiator (inorganic peroxy salt) of main initiator (water) in the putty has all been run out, putty during also by beginning rare thick body of paste be solidified into solids gradually.
Having realized using water as the putty product that solidifying agent prepares the present invention through above-mentioned each step can be in room temperature (normal temperature) down dry (curing).
