The invention discloses an ardealite curb and a preparation method thereof, belongs to the technical field of ardealite curb processing, and aims to solve the problems of long production cycle, large use amount of a gel material, low compressive strength and high cost of the existing curb. The ardealite road tooth is prepared from the following components in parts by weight: 350 to 550 parts of modified ardealite, 156 to 244 parts of stone, 233 to 367 parts of aggregate, 24 to 38 parts of ash residue, 4 to 6 parts of polyvinyl alcohol, 0.8 to 1.2 parts of calcium formate, 1.6 to 2.4 parts of hydroxypropyl methyl cellulose and 8.6 to 13.5 parts of accelerator, the components are uniformly mixed and stirred, then water is added for stirring, a semi-dry mixture obtained by stirring is filled into a mold, the mold is punched and formed after vibration, and demolding and natural curing are performed after forming. The use of a gelling agent is reduced, the production cost is reduced, the production period is shortened, and the economic benefits of enterprises are greatly improved.
本发明公开了一种磷石膏道牙及其制备方法，属于磷石膏道牙加工技术领域，以解决现有道牙生产周期增长、凝胶材料使用量大、抗压强度低和成本高的问题。一种磷石膏道牙，按照重量份数计包括以下组份：改性磷石膏350‑550份、石子156‑244份、骨料233‑367份、灰渣24‑38份、聚乙烯醇4‑6份、甲酸钙0.8‑1.2份、羟丙基甲基纤维素1.6‑2.4份和速凝剂8.6‑13.5份；本发明组份混合搅拌均匀，再添加水进行搅拌，搅拌得到的半干混合料填入模具内，经震动后冲压成型，成型后脱膜自然养护。本发明减少胶凝剂的使用、减少生产成本低和降低生产周期，极大提高企业经济效益。
