Abstract

The invention discloses a wear-resistant quartz stone sheet material. The wear-resistant quartz stone sheet material comprises the following components in percentage by mass: 25 to 36% of quartz powder, 40 to 50% of quartz sand, 1 to 2% of a silane coupling agent, 1 to 2% of a curing agent, 1 to 3% of sodium silicate, 5 to 10% of polypropylene fiber, and 8 to 15% of polyurethane resin. According to the invention, sodium silicate, the polypropylene fiber and the polyurethane resin are added and matched with other raw materials, so that wear resistance of the artificial quartz stone sheet material can be effectively improved and the strength of the artificial quartz stone sheet material is enhanced, and then the quartz stone sheet material can withstand the influence of the external environment on performances of the sheet material, and can be used in low temperature or high temperature and in other places with relatively harsh environments.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a wear-resistant quartz stone plate and a preparation method thereof. Background technique [0002] At the beginning of the 21st century, artificial quartz stone technology was introduced into China from abroad. Nowadays, artificial quartz stone is the latest artificial building material with high strength, high hardness, high temperature resistance, corrosion resistance, aging resistance, easy cleaning, wear resistance, The incomparable advantages of natural stone such as pure material and no radiation. Today, as natural stone is being exhausted as a non-renewable resource, artificial quartz stone is the best substitute. At the same time, artificial quartz stone can use waste glass as raw material, thus realizing resource reuse while protecting the environment. These advantages make Artificial quartz stone has become an upstart in the architectural decora...
