Embodiment 1
[0032] Embodiment 1, a kind of preparation method of silicon dioxide particle for scrub cream
[0033] The preparation method of silicon dioxide granule for described scrub, comprises the following steps:
[0034] S1, the water glass with a modulus of 3.4 is diluted with water to dissolve and aged for 4 hours, and then the aged water glass is diluted with water to be configured into water glass solutions with a concentration of 0.7mol / L and 1.2mol / L respectively;
[0035] S2, configuration concentration is that the sulfuric acid solution of 5mol / L and the sodium sulfate solution that mass percentage is 12% are standby;
[0036] S3, add 4m in reaction tank 3 The sodium sulfate solution prepared in step S2 was heated to 50° C., and after starting the stirring device, 4 kg of sodium polyacrylate and 2 kg of hydroxypropyl cellulose were added, and stirred and dispersed for 20 min at a stirring frequency of 35 Hz;
[0037] S4, in the state of stirring, continue to add dropwise simu...
