step 2: melting 70 parts of asphalt to obtain asphalt liquid, adding 1 part of asphalt liquid and water glass into the rosin soap emulsion prepared in the step 1, and stirring for 20min to obtain emulsified asphalt, wherein the asphalt is 60 # petroleum asphalt;
step 3: adding water into bentonite, 8 parts of styrene, 8 parts of butyl acrylate and 4 parts of oleic acid at 50 ℃ for stirring for 30min, adopting a gradient heating mode for stirring, increasing the temperature by 10 ℃ every 10min at room temperature, and stirring for 30min until the temperature reaches 50 ℃;
step 4: and (3) stirring and mixing 26 parts of the mixture obtained in the step (3) and the liquid polyurethane resin in emulsified asphalt at the temperature of 40 ℃ to obtain the liquid waterproof coiled material.
Comparative example 2 differs from example 5 in that bentonite was not pretreated.
Comparative example 3:
step 1: heating 90 parts of deionized water to boiling, adding 5 parts of sodium hydroxide to dissolve the deionized water, adding 7 parts of rosin soap in a fine powder state under stirring, and continuously stirring for 90min to obtain rosin soap emulsion, wherein the rosin soap is rosin sodium soap;
step 2: melting 70 parts of asphalt to obtain asphalt liquid, adding 1 part of asphalt liquid and water glass into the rosin soap emulsion prepared in the step 1, and stirring for 20min to obtain emulsified asphalt, wherein the asphalt is 60 # petroleum asphalt;
step 3: pretreating 16 parts of bentonite with the particle size of 100 meshes, dispersing the bentonite in 16 parts of deionized water under the stirring action to form bentonite suspension, adding 4 parts of octadecyl trimethyl ammonium chloride, stirring and dissolving, filtering, drying the filtrate, and grinding to prepare the organic bentonite;
step 4: adding water into 8 parts of organic bentonite, 8 parts of styrene, 8 parts of butyl acrylate and 4 parts of oleic acid at 50 ℃ for stirring for 30min, adopting a gradient heating mode for stirring, heating to 10 ℃ every 10min at room temperature, and stirring for 30min;
step 4: and (3) stirring and mixing the mixture obtained in the step (3) in emulsified asphalt at the temperature of 40 ℃ to obtain the liquid waterproof coiled material.
Comparative example 3 differs from example 5 in that no liquid polyurethane resin was added.
The liquid waterproof coiled materials prepared in examples 1 to 5 and comparative examples 1 to 3 were subjected to aging-related tests including high temperature resistance and low temperature resistance, and the test results were as follows:
in the test result, the high temperature resistant project, the test value is the bearable point value of the liquid waterproof coiled material, and after exceeding the point value, the liquid waterproof coiled material has dripping condition; and the test value is a point value which can be born by the liquid waterproof coiled material, and after the test value exceeds the point value, the liquid waterproof coiled material has cracks. As shown by test results, the high temperature resistance and the low temperature resistance of the general examples are better than those of the comparative examples, the emulsified asphalt of the comparative example 1 alone has obvious disadvantages in terms of high temperature resistance and low temperature resistance, the liquid waterproof coiled material is slightly worse in terms of low temperature resistance because the bentonite is not subjected to pretreatment in the comparative example 2, and the liquid waterproof coiled material is slightly worse in terms of high temperature resistance and low temperature resistance because the liquid polyurethane resin is not added in the comparative example 3.
For the waterproof performance and the bonding strength test of the waterproof roll foundation, the liquid waterproof roll in the embodiment meets the standard requirement.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
