Embodiment Construction
[0012] A preparation method of calcium sulfate whisker floor tiles includes the following process steps:
[0013] 1) Prepare the ingredients, which are composed of the following parts by weight: 13 parts of plastic particles, 12 parts of silica gel, 33.5 parts of plasticizer, 1.5 parts of dispersant, 95 parts of high-strength gypsum, 11 parts of titanium dioxide, 3 parts of calcium sulfate whiskers , 3.5 parts of dibasic lead stearate, 3.2 parts of coupling agent titanate, 5 parts of diatomaceous earth, 0.6 parts of pigment;
[0014] 2). First crush the high-strength gypsum and titanium dioxide, then put them into the mixer together with plastic particles, silica gel and plasticizer, stir at 1350r / min for 20 minutes, add the remaining raw materials, and then stir at 1200r / min for 30 minutes , The temperature is controlled at 120℃, and the mixture is prepared;
[0015] 3) Put the mixture into a steam-curing kettle at 290°C, from normal pressure to 1.3MPa, the pressure increase proce
