Abstract

The invention discloses a limestone tailing ceramic tile adhesive. The adhesive is characterized by comprising the following components in parts by weight: 350-400 parts of cement, 50-100 parts of heavy calcium carbonate powder, 20-50 parts of redispersible latex powder, 1.5-5 parts of cellulose ether, 1-3 parts of calcium formate, 0.5-1 part of a layered water repellent agent, 0.3-0.5 part of sodium gluconate and the balance of limestone tailings, and the total amount of the components is 1000 parts. According to the ceramic tile adhesive disclosed by the invention, all aggregates adopt limestone tailings to replace quartz sand, tensile bonding strength and slippage of soaking, thermal aging, freezing and thawing cycle airing time and the like all meet related standard requirements, and the tensile bonding strength and original strength performance are greatly improved.

Description

technical field [0001] The invention relates to the field of solid waste recycling, in particular to an adhesive for limestone tailings ceramic tiles. Background technique [0002] Cement is one of the pillar industries of my country's building materials industry. In 2020, the total amount of cement produced in the country will exceed 2 billion tons. In the process of cement production, a large amount of limestone needs to be mined as raw materials. Calculated based on the consumption of 1.5 tons of limestone per ton of cement production, At least 3 billion tons need to be mined every year, accompanied by a large amount of non-metallic tailings, which will pollute the water and soil and cause great damage to the human environment. How to rationally use solid waste and reduce the production cost of products is the future building material industry trends. [0003] Traditional cement is used in the current high-density ceramic tiles, which can cause safety hazards such as easy ...
