Abstract
The invention provides a preparation method of an organic silicon defoamer. The organic silicon defoamer contains the following raw materials in parts by weight: 30-40 parts of dimethyl silicon oil, 28-38 parts of silicone grease, 15-18 parts of polyoxyethylene stearate, 12-18 parts of sorbitan tristearate, and 120-143 parts of water. The preparation method comprises the following steps: heating one third of 120-143 parts of water to 60-68 DEG C; adding sorbitan tristearate and polyoxyethylene stearate under a stirring condition; after uniform melting, adding silicone grease and dimethyl silicon oil under a stirring condition; adding the rest water at the temperature of 60-68 DEG C; and stirring for 40 minutes, thereby obtaining the defoamer. The defoamer is applicable to the field of papermaking and other industries of automobile anti-freezing liquid and the like, and a good effect can be achieved just by adding 20g of defoamer into 1t of paper pulp.
