Description
Technical field
The present invention relates to a kind of coating, be specially a kind of hydrophobicity silicate frie retardant coating and preparation method thereof.
Background technology
" floods and fires have no mercy ".Fire is the common wicked problems that the whole world faces, and it has caused huge life and property damage to human society.Inorganic paint has excellent fire line, ventilation property, resistance to crocking and good synthesized environmental protection performance.Along with people's is greatly developed inorganic fireproof coating and has been become new trend again the fire line of trade sales coating, the more and more strictness of requirement of environmental protection aspect.
Frie retardant coating at first grows up from inorganic fireproof coating.Abroad, adopted aqueous fire-proof coating very early, it is sticker that 20th century just had with water glass in early days, adds the inorganic fireproof coating that mineral are filler.Water glass is the frie retardant coating of base-material, can produce silicate foam shape thermofin when meeting fire, has good flame retardation effect, does not produce advantages such as toxic gas, but because of its poor water resistance, coating is prone to come off and has limited it and used to receive water logging to steep afterwards.In order to improve its water tolerance, adopt usually sour modification, with methods such as compound, the crosslinking curing modification of organic membrane, deficiencies such as lack but exist solidification value height, poor stability, coating to be prone to layering, shelf-time.In addition, water glass is that the high fragility of the coating hardness of base-material is big, its easy of crack of filming.Thereby, how to improve the key issue that water tolerance, snappiness and film-forming properties that water glass is the frie retardant coating of base-material become inorganic silicate coating.
Summary of the invention
