The asphalt emulsion comprises, by mass, 15% of asphalt, 15% of naphthenic oil, 20% of styrene-butadiene rubber latex, 20% of chloroprene latex, 7% of acrylic emulsion, 1% of emulsifier, 1.5% of anti-aging agent, 0.5% of dispersant and 20% of water in soap solution.
The powder slurry comprises 20 percent of tap water, 1 percent of dispersant and 79 percent of nano calcium powder by mass percent
The procedure for preparing the high solid content water-based non-curable waterproofing paint of this example is the same as that of example 1.
The coatings prepared in examples 1 to 8 were tested according to the test method prescribed in national standard GB/T16777-2008 "test method for waterproof coating for building" (official reference), and the results are shown in Table 1, which is the average value of the tests in each example of the present invention.
From the comparison results in table 1 above, it can be seen that:
(1) the coating prepared by the invention has good performances such as high-temperature strength and the like, and the average solid content of the coating exceeds 75 percent and can reach 80 percent at most, which is far higher than that of a commercial waterproof coating;
(2) the waterproof paint has good high-temperature resistance, the average heat-resistant temperature of the waterproof paint is 80 percent, the highest heat-resistant temperature can reach 95 ℃, and the waterproof paint is suitable for waterproof treatment of exposed or roof-top and other high-temperature base surfaces.
(3) The waterproof paint has good low temperature resistance, can reach-30 ℃ on average, can not break at the lowest temperature of-35 ℃, has no cracks, and is suitable for the waterproof treatment of the base surface in the low-temperature area in the north.
(4) The waterproof coiled material has good adhesive property, can be constructed on wet base surfaces and dry base surfaces, can be matched with a waterproof coiled material for use, has good adhesive force and stress resistance, and has the outstanding characteristic of being fully adhered to various base surfaces and not leaking water.
Of course, the above description is not limited to the above examples, and the undescribed technical features of the present invention can be implemented by or using the prior art, and will not be described herein again; while the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that various changes, modifications, additions and substitutions can be made without departing from the spirit of the invention and the scope of the invention as defined in the accompanying claims.
Claims (1)
