Joint filling material for building exterior wall

Abstract

The invention discloses a joint filling material for a building exterior wall. The joint filling material is prepared from, by mass, 100-200 parts of cement, 100-200 parts of coal ash, 100-200 parts of building debris powder, 100-200 parts of lime powder, 50-70 parts of calcium carbonate, 70-100 parts of sintered pellets, 80-100 parts of mineral powder, 100-150 parts of iron powder, 10-15 parts of antioxidant, 10-15 parts of water reducer, 30-50 parts of quartz powder and 200-250 parts of water. The joint filling material can be effectively attached between tiles to seal tile joints, the phenomena of cracking and shedding can be effectively avoided after sealing, and then the phenomenon that moisture permeates into the wall and makes the tiles shed is avoided.

Description

technical field [0001] The invention relates to a joint filling material for building exterior walls. Background technique [0002] The laying of ceramic tiles has become a common decoration in daily life. From home to hotels and other public places, from the ground to the wall, the decorative effect brought by ceramic tiles cannot be underestimated. However, in the process of laying and laying, bricks and bricks The joints between the blocks need to be specially treated. At present, the commonly used joint sealant is cement mortar, which has low adhesion and is prone to cracking after curing, thereby absorbing water. If it encounters thermal expansion and contraction, it will Cause the tiles to burst, or too much water seeps in and the adhesion between the tiles and the wall is not strong enough to fall off. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of caulking material for exterior walls of buildi...
