Abstract
The invention discloses a fireproof facing mortar composite layer. The fireproof facing mortar composite layer comprises a screed-coat, a surface layer and a coating, wherein the screed-coat is mainlyprepared from low-temperature calcination graphite, portland cement, quartz sand, rubber powder and a water-retaining agent, the surface layer is prepared mainly based on an aluminate cement-rich composite cementing material system (HAC-OPC-CS), and the coating is mainly prepared from silicone acrylic emulsion and nano-hybrid resin. By the multilevel composite fireproof mechanism of the screed-coat, the surface layer and the coating, the fireproof facing mortar composite layer achieves relatively good fireproof performance on the whole. The mortar composite layer obtained by the invention hasgood binding power with the basic surface of a wall body, and as inorganic materials account for the vast majority of ingredients, the mortar composite layer is particularly suitable for the decorative design of architectural outer walls of villas, foreign-style houses and the like.
Description
technical field [0001] The invention relates to the field of wall insulation materials, in particular to a fire-resistant decorative mortar composite layer. Background technique [0002] At present, the commonly used exterior wall decoration materials on the market are roughly divided into three systems: ceramic tile system, paint system, and facing mortar system. The three major systems have their own advantages and disadvantages. The tile system is limited by the nature of the tile itself (self-weight, size, water absorption, air permeability, etc.), and it is more prone to bonding failure, resulting in hollowing or even falling off. It is not suitable for thermal insulation systems. Paste; the bonding strength of the coating system is mainly derived from the van der Waals force of the organic material, peeling and peeling occur from time to time, and poor air permeability leads to frequent bubbling of the coating product, and yellowing of organic pigments under ultraviole...
