A kind of high rigidity, vapor-proof waterproof paint
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of high rigidity, vapor-proof waterproof paint.
Background technology
Existing waterproof paint has multiple, some constructing operation complexity and poor performance; Some waterproof effects are poor, and weather resistance is poor; What have needs not only construct trouble but also exist batching to be forbidden to cause degradation to affect waterproof effect of field mix; The easy generation bubble having, surface gloss is bad, and it is necessary therefore producing a kind of high performance waterproof paint.
Summary of the invention
The object of the invention is just to provide a kind of high rigidity, vapor-proof waterproof paint.
The present invention is achieved by the following technical solutions:
, a vapor-proof waterproof paint, it is comprised of the raw material of following weight parts:
The fluoro-silicone emulsion 60-70 of solid content >=25%, talcum powder 7-9, Tremoliteor Tremoliteasbestos powder 15-20, calcined kaolin 1-2, superfine alumina silicate 2-3, soybean protein powder 2-4, polyvinyl acetate emulsion 10-20, sodium starch phosphate 1-2, methacrylic acid ten trifluoro monooctyl ester 2-3, ammonium meta-vanadate 0.3-0.4, dehydrated alcohol 2-4, adhesive aid 10-20, deionized water 10-30;
Described adhesive aid is comprised of the raw material of following weight parts:
Polyvinyl acetate emulsion 30-40, polyvinyl alcohol 6-10, Radix Notoginseng powder 2-3, carbomer 4-6, N-ethyl-neighbour, para toluene sulfonamide 0.5-1, sodium silicoaluminate 2-3, water are appropriate;
Above-mentioned sodium silicoaluminate is mixed with polyvinyl alcohol, be preheating to 30-40 ℃, ball milling 10-15 minute, joins in this compound weight 3-5 water doubly, be heated to 75-85 ℃, fully stir, add Radix Notoginseng powder, carbomer, rising temperature is 100-120 ℃, being stirred to temperature is 25-30 ℃, add each raw material of residue, fully ball milling, obtains described adhesive aid.
A preparation method for high rigidity, vapor-proof waterproof paint, comprises the following steps:
Above-mentioned talcum powder, Tremoliteor Tremoliteasbestos powder, soybean protein powder, sodium starch phosphate, deionized water are mixed, after stirring, add polyvinyl acetate emulsion, 400-500 rev/min of dispersed with stirring 10-15 minute, add again each raw material of residue, high-speed stirring, to mixing, obtains described high rigidity, vapor-proof waterproof paint.
Advantage of the present invention is:
Waterproof paint waterproof of the present invention, vapor-proof, strong adhesion, becomes film hardness good, not easy to foaming, and resistance to deterioration is good, and hardness is high, good mechanical property, cementability is good, and compactness is good.
