A kind of antimicrobial form asphalt waterproofing paint
Technical field
The present invention relates generally to a kind of coating, particularly relates to a kind of antimicrobial form asphalt waterproofing paint.
Background technology
Emulsified bitumen coating has certain water-repellancy and preservative property, due to the restriction of the performance of pitch own, the work-ing life of Emulsificated asphalt water-proof painting material is short, the poor-performing such as low temperature flexibility and thermotolerance, being applicable to classification of waterproof is waterproof layer and underground is moistureproof, the construction of corrosion protection coating between the industry of III, IV grade and covil construction roofing, lavatory are bathed, and is cheap low-grade waterproof paint, therefore, improve the over-all properties of Emulsificated asphalt water-proof painting material, so that it is necessary for expanding usage range.
Summary of the invention
The object of the invention is just to provide a kind of antimicrobial form asphalt waterproofing paint.
The present invention is achieved by the following technical solutions:
A kind of antimicrobial form asphalt waterproofing paint, it is made up of the raw material of following weight parts:
Pitch 63-70, acrylate and vinyl acetate emulsion 6-7, polyacrylamide 2-3, Sodium Silicofluoride 1-2, polypropylene glycerol aether 1-2, aminopropyltriethoxywerene werene 1-2, aluminium hydrate powder 1-2, swelling perlite powder 12-20, fluorite powder 10-20, methylisothiazolinone 2-3, film coalescence aid 2-4, water are appropriate;
Described film coalescence aid is made up of the raw material of following weight parts:
EVA emulsion 40-50, polyvinyl acetate emulsion 5-6, vinyltriethoxysilane 4-5, dipropylene glycol butyl ether 1-2, cetomacrogol 1000 2-3, aluminium hydroxide 2-4, tin-antiomony oxide 0.1-0.2;
Above-mentioned cetomacrogol 1000 is mixed with aluminium hydroxide, stirring reaction 10-15 minute at 50-60 DEG C, tin-antiomony oxide is added after being cooled to normal temperature, obtain Preblend, EVA emulsion is mixed with polyvinyl acetate emulsion, stir after evenly and add vinyltriethoxysilane, 400-500 rev/min dispersed with stirring 2-4 minute, adding above-mentioned Preblend and each raw material of residue, 100-120 DEG C of insulation leaves standstill 1-2 hour, obtains described film coalescence aid.
A preparation method for antimicrobial form asphalt waterproofing paint, comprises the following steps:
Above-mentioned pitch is heated to 140-150 DEG C, adds polyacrylamide, Sodium Silicofluoride, methylisothiazolinone, obtain Preblend; Swelling perlite powder, fluorite powder are mixed with aminopropyltriethoxywerene werene, 500-600 rev/min dispersed with stirring 4-5 minute, join in above-mentioned Preblend after discharging, by colloidal mill grinding evenly, add each raw material except film coalescence aid, fully it is uniformly mixed at 90-100 DEG C, it is cooled to normal temperature, add film coalescence aid, fully stir, obtain described antimicrobial form asphalt waterproofing paint.
It is an advantage of the invention that:
The coating of the present invention and base face cohesiveness are strong, and good water-proof effect, weathering resistance, acid-alkali-corrosive-resisting, resistant of high or low temperature, contamination resistance, germ resistance are strong.
