Abstract

The invention relates to anti-freezing anti-cracking anti-leaking mortar for inner and outer wall plastering, and belongs to the field of building materials. The anti-freezing anti-cracking anti-leaking mortar is characterized by being prepared from, by weight, 20-30 parts of cement, 50-65 parts of medium-fine sand, 1.0-2.0 parts of a waterproof agent, 0.1-0.3 part of tributyl phosphate, 0.1-0.3 part of triethanolamine, 0.3-1.5 parts of high-strength high-modulus polyvinyl alcohol fibers, 3.0-6.5 parts of 108 an adhesive, 0.1-1.4 parts of an anti-freezing agent and 10-15 parts of water. Compared with the prior art, the anti-freezing anti-cracking anti-leaking mortar has the advantages that the binding power between the mortar and a building basement layer can be greatly increased, the advantages of being high in viscosity, capable of resisting cracking and leaking and the like are achieved, and the problems of wall leaking and mildewing caused by a wall material or improper construction can be effectively solved.

Description

technical field [0001] The invention relates to a mortar in the field of building materials, in particular to an antifreeze, crack, and leakage-proof mortar for plastering interior and exterior walls. Background technique [0002] The surface construction of the interior and exterior walls of construction projects generally adopts grass-roots plastering. Exterior wall decoration sticks exterior wall bricks or colored paint, and interior wall decoration "scrapes white" or pastes wallpaper. Grass-roots plastering has become a typical "concealed project". The mortar used for base plastering is generally common mortar, which is to mix construction sand and cement in a certain proportion and add an appropriate amount of water to stir evenly. Using this kind of mortar to plaster the interior and exterior wall ash generally has weak cohesive force, easy cracking, sticky bricks are easy to hollow out and fall off, easy to leak in rainy season, and easy to mold on the interior wall i...
