Problems solved by technology

There are also various problems in the construction process of different thermal insulation mortars. At present, most of the new wall materials in China cannot meet the requirements of 65% energy-saving standards. Quality problems such as cracking, falling off, and water seepage in the wall have left major safety hazards for the external insulation project

Abstract

The invention relates to a ready-mixed plastering mortar for an exterior wall, and a production method thereof. The ready-mixed plastering mortar is characterized by comprising the following raw materials in parts by weight: 60-70 parts of artificial sand, 12-13 parts of cement, 10-12 parts of II-grade pulverized coal ash, 2-3 parts of glass beads, 2-3 parts of redispersible latex powder, 1 part of hydroxypryopyl guar gum ether, and 0.1-0.5 part of additive. According to the ready-mixed plastering mortar for the exterior wall, by adopting glass beads, redispersible latex powder and hydroxypryopyl guar gum ether as functional auxiliaries, the mortar has excellent tensile adhesive strength, heat retaining property and water retaining property; and through adopting the additive, the anti-seepage, anti-cracking and shrinkage reduction properties of the mortar can also be remarkably improved.

Description

technical field [0001] The invention belongs to the processing field of ready-mixed mortar, in particular to a ready-mixed plastering mortar used for exterior walls and a production method thereof. Background technique [0002] Mortar is one of the most widely used building materials in construction engineering, and it is widely used in masonry and plastering of buildings. In my country's current construction projects, more than 60% of buildings still use wall materials such as bricks and blocks, and the construction mortar used in masonry and plastering construction is still mainly cement mortar or mixed mortar. [0003] With the technological progress of the construction industry and the improvement of civilized construction requirements, the on-site mixed mortar has increasingly shown its inherent defects, such as unstable mortar quality, large waste of materials, single type of mortar, low degree of civilized construction, and environmental pollution. Therefore, it is i...
