Embodiment 1
[0027] The invention discloses a recyclable stable foam, which is composed of a base liquid and an antifoaming agent, wherein: the base liquid includes: 0.5-1.5 parts of a foaming agent, 0.1-0.3 parts of a stabilizer, 6- 8 parts of inhibitor, 1-3 parts of wetting reversal agent and 100 parts of water; the defoamer is silicone oil emulsion type defoamer, and the volume percentage of defoamer and base liquid is 0.066-0.068%. In this scheme, said foaming agent, stabilizer, inhibitor, wetting reversal agent and defoamer can adopt the existing products of various models common in the art, and the preparation method can adopt the existing products in the art. Conventional preparation methods in the art.
Embodiment 2
[0029] As a comparatively best embodiment of the present invention, adopt following scheme to have best effect through following test:
[0030] The base liquid includes in parts by weight: 1 part of foaming agent, 0.2 part of stabilizer, 7 parts of inhibitor, 2 parts of wetting reversal agent and 100 parts of water; the defoamer is silicone oil emulsion type defoamer The volume percentage of foaming agent, defoamer and base fluid is 0.067%.
