preparation example Construction

[0029] The embodiment of the present invention also provides a method for preparing a nano-waterproof material for construction, which includes the following steps:

[0030] Preparation of mixed emulsion: mix acrylic resin and silicone acrylic emulsion, then add dodecyl alcohol ester dropwise while stirring, and obtain mixed emulsion after the stirring reaction is completed;

[0031] Mixing of filler additives: sieve diatomaceous earth, then put it into a blender with nano-titanium dioxide and nano-silica powder, first add 5-10 parts of water, then add dispersant, defoamer, bactericide and the remaining water, stir and mix to obtain filler additives;

[0032] Finished product preparation: Mix the mixed emulsion with filler additives, stir and react to get the finished product.

[0033]In the above examples, firstly, through the above mixed emulsion preparation steps, the acrylic resin and the silicone acrylic emulsion are mixed, and the dodecyl alcohol ester is added dropwise...

Embodiment 1

[0044] The embodiment of the present invention provides a nano-waterproof material for construction, which is prepared through the following steps:

[0045] Mixed emulsion preparation: Mix 50g of acrylic resin with 30g of silicone acrylic emulsion, then add 0.5g of dodecyl alcohol dropwise while stirring at 60-80°C, the stirring rate is 1000rpm, and react for 45min. After the stirring reaction is completed, a mixed emulsion is obtained;

[0046] Mixing of filler additives: Take 10g of diatomaceous earth and pass through a 300 mesh sieve, and then put 10g of nano-titanium dioxide with a particle size of 25nm and 1g of nano-silicon micropowder with a particle size of 60nm into a blender, first add 5g of water, and mix at 60 At ℃, add 0.5g of dispersant, 0.5g of defoamer, 0.2g of bactericide and the remaining 10g of water while stirring, stir at 1000rpm for 45min, and obtain the filler additive after stirring;

[0047] Finished product preparation: Mix the mixed emulsion and fill...
