Problems solved by technology

[0004] The current mortar is generally not waterproof, easy to crack and other defects
For example, when traditional mortar is applied to bricklaying, the wall surface is prone to cracking or permeable; while traditional mortar is applied to decorative plastering, since the mortar is not waterproof, it will crack as soon as the plastering mortar dries out, and it will last for 3-5 years. will fall off naturally

Abstract

The invention discloses a waterproof anti-crack mortar composition. The composition specifically comprises quartz sand, cement, light calcium carbonate, hydroxypropyl methyl cellulose, segmented fibers, starch ether and redispersible rubber powder. According to the mortar, the hydroxypropyl methyl cellulose, the anti-cracking fibers, the starch ether and the redispersible rubber powder are used asauxiliary materials for improving the comprehensive performance of the mortar, so that the waterproof anti-crack mortar composition has remarkable waterproof, anti-cracking and anti-falling effects,and the service life of the mortar is more than three times that of traditional mortar. By using the method, the construction amount is reduced, the construction efficiency is improved, the labor costis reduced, and the cost is greatly reduced. Meanwhile, the product is simple to use, can be used by adding a proper amount of water and then stirring uniformly, is convenient and quick, is an idealnovel building material, and is very worthy of vigorous popularization.

Description

technical field [0001] The invention belongs to the field of new production technology of building materials, and in particular relates to a waterproof and crack-resistant mortar composition. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. It is also called mortar and mortar. [0003] Commonly used mortars are cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. According to the composition materials, ordinary mortar can also be divided into: ①lime mortar. It is made of lime paste, sand and water in a certain ratio, and is generally used for masonry and plastering layers that do not require high strength and are not subject to moisture; ②Cement mortar. It is made of cement, sand and water according to a certain ratio, and is generally used for masonry, walls or floors in humid environments or in...
