| Abstract: | Sodium Silicate as base material is modified by using sodium fluorosilicate in appropriate amount and organic amine as modfication accalerator to coordinate the interrelation of viscidity and water tolerance and gelation time. Firming agent is prepared by using phosphoric acid, silicon oxide, zinc oxide, aluminium salt, calcium salt and barium salt as raw materials. The polymerization of sodium silicate and gel condensation of silicon dioxide are accelerated by using the firming agent.Auxiliary film forming matter is made of phenypropyl emulsion. Then the prescription is optimized by orthogonal method.Thus a sodium silicate composite coating with good water tolerance and strong adhesion is prepared. The coating is characterized by cheap in cost, pollution free and aging resistant. It can be applied as fire proofing coating and outer wall coating. |
