The invention relates to a preparation method of nano porcelain-imitating sand grains. The preparation method of the nano porcelain-imitating sand grains comprises the following steps: S1, preliminarily preparing silicon dioxide nano powder; S2, performing further crushing treatment on the preliminarily prepared silicon dioxide nano powder by performing ultrasonic crushing in the starting process of an ultrafine crusher, so as to obtain a finished product of silicon dioxide nano powder; S3, preparing a mixed material group; S4, pressing the mixed material dough into sheets, then putting the mixed material dough sheets into a mold, and pressing the mixed material dough sheets into granular mixed material dough particles; and S5, after demolding the mixed material cluster particles, heating the mixed material cluster particles at high temperature again, and finally naturally cooling the mixed material cluster particles to prepare the nano porcelain-imitating sand grains. According to the preparation method of the nano porcelain-imitating sand grains, the materials are all healthy materials, so that the health of children is not harmed, the wear resistance of mixed material balls and particles is improved, and the mixed material balls and particles are not decolored.
本发明涉及一种纳米仿瓷沙粒制备方法，所述一种纳米仿瓷沙粒制备方法包括如下步骤：S1：初步制备二氧化硅纳米粉；S2：对初步制备的二氧化硅纳米粉，超细粉碎机开启的过程中，介入超声粉碎进行进一步粉碎处理，得到成品的二氧化硅纳米粉；S3：制得混合材料团；S4：将混合材料团压制成片，接着将混合材料团片放入模具中，压制成颗粒状的混合材料团颗粒；S5：混合材料团颗粒脱模后，将混合材料团颗粒再次进行高温加热，最后混合材料团颗粒自然降温，制备成纳米仿瓷沙粒。该纳米仿瓷沙粒制备方法，改材质采用的均为健康材质，不会对儿童的健康产生危害，增大了混合材料团颗粒的耐磨性，混合材料团颗粒也不会产生脱色的情况。
