Abstract

The invention discloses an ultrathin quartzite plate and a preparation method thereof, and relates to the technical field of plate processing. The ultra-thin quartzite plate is prepared from 30%-50% of quartz sand, 20%-30% of quartz powder, 10%-30% of unsaturated polyester resin, 10%-15% of zirconium phosphate, 5%-10% of nanometer aluminum oxide, 0.1%-2% of an accelerant, 1%-5% of a curing agent and 1%-5% of a coupling agent, wherein the particle size of the nanometer aluminum oxide is 1-5 nm. A certain amount of zirconium phosphate and nano aluminum oxide are added into a raw material system, and the composition of the raw material system is adjusted, so that the prepared quartzite plate has relatively high compactness, and the hardness of the plate is further improved. The thickness of the quartzite plate is processed to be 0.9-1.0 cm, and meanwhile, the Mohs hardness value is kept to be 7.5 or above.

Description

technical field [0001] The invention belongs to the technical field of quartz stone plate processing, and in particular relates to an ultra-thin quartz stone plate and a preparation method thereof. Background technique [0002] Quartz stone slab is a new type of artificial marble made of more than 90% quartz crystal combined with resin and other additives. Quartz stone plate has the advantages of high hardness, no radiation, zero pollution, high temperature resistance and wear resistance. As the thickness of the quartz stone plate decreases, its hardness and wear resistance are greatly reduced, so the thickness of the artificial marble (that is, the quartz stone plate) is generally above 1.2cm. The thickness of artificial marble is less than 1.2cm, not only the molding rate is low, but also the hardness requirement is difficult to meet the actual demand. [0003] For this reason, reducing the thickness of artificial marble and making it have higher hardness is an important...
