Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Examples
When the hydrophobic plastic agent is implemented, the hydrophobic plastic agent mainly comprises the following raw materials in parts by weight: based on the total weight of the prepared molding agent, the content of the hyperfine silicon dioxide is 5 to 8 percent, the content of the starch is 35 to 40 percent, and the balance is water. Wherein, the specification of the superfine silicon dioxide is 400 meshes, namely the particle size of the powder is about 38 microns, and the customization requirement of the product is that the passing rate of a 400-mesh screen is not less than 90%.
The process for preparing the hydrophobic plasticizer comprises the following steps, S1: fully mixing silicon dioxide powder and water according to a ratio, controlling the temperature to be 80-90 ℃, wherein the frequency of a first stirring motor is 10Hz and the stirring time is about 1.5h when stirring and mixing;
