Application of starch octenyl succinate, building mortar, putty and tile glue

Abstract

The invention provides an application of octenyl succinic acid modified starch in building mortar, putty or tile glue. According to the invention, starch octenyl succinate is added into cement-based mortar (thermal insulation mortar, bonding mortar, anti-crack mortar and cement mortar for plastering an inner wall), gypsum-based mortar (thermal insulation gypsum plastering mortar, gypsum mortar for plastering a bottom layer of the inner wall or gypsum mortar for plastering a surface layer of the inner wall), cement-gypsum mixed mortar building mortar ( lightweight mixed mortar for interior wall bottom layer plastering, cement main material-based self-leveling mixed mortar or gypsum main material-based self-leveling mixed mortar), cement-based putty (exterior wall waterproof putty or cement-based interior wall putty (N-type)), gypsum-based putty (sound-absorbing gypsum putty for interior wall surface layer plastering, gypsum interior wall putty (Y-type), gypsum interior wall putty (N-type) or ash-calcium-based interior wall putty (N-type)) or tile adhesive, so the building mortar, the putty or the tile adhesive is ensured to have the properties of light weight, sound absorption, impression and the like, and meanwhile, the building mortar, the putty or the tile adhesive is ensured to have high strength.

Description

technical field [0001] The invention relates to the technical field of cement gypsum-based mixed mortar, in particular to the application of starch octenyl succinate, construction mortar, putty and tile glue. Background technique [0002] The requirements for wall materials in today's market are light weight, durability, low renovation rate, high strength, and scratch resistance. Construction mortar, putty, and tile adhesive are important components of the interior and exterior walls, which directly affect the quality of the walls of the building. However, the existing building mortar, putty, and tile adhesive generally have insufficient strength. For example, the strength cannot be guaranteed when light weight, sound absorption, and appearance are guaranteed, and the insufficient strength leads to premature cracking, falling off, and wall damage. There are many problems such as shortened body life, shortened wall renovation period, and high post-maintenance costs. Conten...

However, the existing building mortar, putty, and tile adhesive generally have insufficient strength. For example, the strength cannot be guaranteed when light weight, sound absorption, and appearance are guaranteed, and the insufficient strength leads to premature cracking, falling off, and wall damage. There are many problems such as shortened body life, shortened wall renovation period, and high post-maintenance costs.
