Abstract

The invention relates to a self-clean self-purification cement-based facing material and a production method thereof. The self-clean self-purification cement-based facing material comprises the following components in parts by weight: 20-30 parts of white silicate cements, 5-10 parts of mineral admixtures, 0-20 parts of quartz sands of 20-30 meshes, 20-30 parts of quartz sands of 40-70 meshes, 20-30 parts of quartz sands of 70-100 meshes, 1-4 parts of kieselguhr, 2-4 parts of zeolite, 0.2-0.6 part of nanometer titanium dioxide, 0.5-2.0 parts of EVA redispersible latex powder, 0.2-0.8 part of organic silicon water repellent, 0-1 part of ferric oxide inorganic pigment and 0.1-0.7 part of other chemical additive. The self-clean self-purification cement-based facing material, provided by the invention, has the advantages of good self-clean property, good self-purification property, good air purification capacity, good adhesive property, good construction property, good endurance quality, higher compression strength and the like, when the self-clean self-purification cement-based facing material is used for decoration of facings of an inner wall space and an outer wall space of a building, the air purification effect and the decoration effect are good, and the self-clean self-purification cement-based facing material can be applied for decoration engineering of all kinds of facings of walls of buildings.

Description

technical field [0001] The invention belongs to the technical field of building materials and also relates to the technical field of functional materials, in particular to a self-cleaning and self-purifying cement-based facing material and a preparation method thereof. Background technique [0002] With the development of my country's economy, people's living standards have improved, and the construction industry has flourished. As an emerging building wall facing material, cement-based facing materials have many advantages and characteristics, such as breathable and water-permeable properties compared with organic coatings. Good, good applicability with wall materials, durable bonding, aging resistance, color not easy to fade, etc. Compared with ceramic tiles, it has the advantages of light weight and convenient construction, especially suitable for surface decoration of wall insulation systems. It can significantly reduce the load of the wall insulation system, and when it i...
