Abstract

The invention discloses a nano additive which comprises the following raw materials in parts by weight: 300-400 parts of 30011C cellulose, 350-500 parts of calcium formate, 50-150 parts of vinyl acetate-vinyl polymerization latex powder, 50-100 parts of SM20, 30-60 parts of bentonite and 30-60 parts of a retarder. Due to adoption of hydroxypropyl methyl cellulose, within a certain addition amount,the workability of mortar can be improved, and the operable time of slurry can be ensured; due to adoption of SM20, the pressure resistance strength and the density can be improved; due to adoption of the vinyl acetate-vinyl polymerization latex powder, the bonding strength of the mortar can be improved; due to adoption of the calcium formate, the early stage strength of the mortar can be improved; due to adoption of the bentonite, the application property of the mortar can be improved; and due to adoption of the retarder, the operable time of the mortar can be prolonged.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a nano additive. Background technique [0002] Due to the beautiful decoration, easy care, easy maintenance and long service life of ceramic tiles, most modern home decoration materials use ceramic tiles as wall and floor decoration materials, and more and more consumers will use ceramic tiles on the wall. As we all know, most of the pasting of domestic tiles in the early days was only on the floor tiles, and the paving of the floor tiles only needed cement and yellow sand. With the upgrading of consumption, more and more tiles are put on the wall, and the quality of the tiles is also upgrading. The hardness and density of the tiles are getting higher and higher, and the water absorption rate is decreasing. This makes ordinary cement sand unable to meet the paste of high-quality tiles. It is prone to safety risks such as shrinkage and tile falling off caused by hollowing. The...
