Marble with high wear resistance, and preparation method thereof

ZHANG DONGFA

The invention relates to the technical field of marbles and preparation methods thereof, and especially relates to a marble with high wear resistance, and a preparation method thereof. The invention aims to improve the wear resistance of the marble. The marble comprises, by weight, 50-70 parts of white cement, 30-50 parts of marble powder, 10-20 parts of aluminum ore, 10-20 parts of glass powder,15-25 parts of bentonite, 5-10 parts of saturated polyester resin, 2-5 parts of a dispersing agent and 1-3 parts of a modifier. The preparation method comprises the following steps: calcining the aluminum ore, grinding, uniformly stirring and mixing with other components, and molding, curing, cutting and polishing the obtained material to obtain the marble. The problems that marble is low in wearresistance, short in service life and poor in impact resistance are solved. The aluminum ore is added into the manufacturing raw materials of the marble, and the aluminum ore is calcined and then ground, so the density of the marble is increased, and the impact resistance of the marble is enhanced; and the hardness and the wear resistance of the marble are improved by controlling the dosage ratioof the white cement to the marble powder to the aluminum ore to the saturated polyester resin.

本发明涉及大理石及其制备方法技术领域，用于提高大理石的耐磨性，尤其涉及一种耐磨度高的大理石及其制备方法，按重量份数计包括以下原料：50‑70份的白水泥，30‑50份的大理石粉，10‑20份的铝矿，10‑20份的玻璃粉，15‑25份的膨润土，5‑10份的饱和聚酯树脂，2‑5份的分散剂，1‑3份的改性剂；制备过程中首先将铝矿进行煅烧之后研磨，再与其他成分搅拌混合均匀，再经过经过成型、固化、切割、抛光后即可得到该大理石；解决了大理石耐磨性低、寿命短、耐冲击性能差的问题，该大理石的制作原料中通过加入铝矿，将铝矿煅烧后研磨，增加了大理石的致密度，增强大理石的耐冲击性，通过控制白水泥、大理石粉、铝矿、饱和聚酯树脂之间的用量比，提高了大理石的硬度和耐磨性能。
