[0036] Example 1
[0037] The preparation method of the base material: 30 to 40% by weight of polyvinyl alcohol glue, 3 to 5% by weight of vinyl acetate-ethylene copolymer emulsion, 0.1 to 0.2% by weight of modified polypropylene fiber and 6 ~10% parts by weight of sodium carboxymethyl cellulose are put into a stirrer (stirring speed ≥120 rpm) and stirred at room temperature for 30 seconds to 1 minute to form a stable colloidal dispersion system, and then add 50-60% Parts by weight of light active calcium carbonate are stirred at room temperature for 8-20 minutes to prepare base material.
[0038] The preparation method of the auxiliary materials: at room temperature, 6-20% by weight of vitrified microbeads (accessory one) and 2-5% by weight of expanded polystyrene (accessory two) particles are added to the concrete mixer and mixed , Then add 5 to 15% by weight of water and stir for 3 to 5 minutes; form a mixed slurry, then add 20 to 25% by weight of white cement (accessory 3) and...
