Problems solved by technology

After the ceramic tile mortar is pasted with ceramic tiles, the mortar is prone to dry shrinkage during the condensation process, resulting in hollowing of the ceramic tiles. The current solution is to brush a layer of back glue on the back of the ceramic tiles to effectively solve the problem of ceramic tiles. The hollowing problem of the pasted ceramic tiles, but in the actual operation process of the back glue, the construction is cumbersome and the cost is high
Therefore, the present i

Abstract

The invention provides ceramic tile pasting mortar and a preparation method thereof. Waste tires are used for preparing machine-made sand, the existence of black garbage is effectively reduced, and meanwhile, the modified waste tire particles have very high ductility and excellent energy absorption performance, and can effectively prevent the dry shrinkage phenomenon of the mortar in the solidification process. A binding agent is added, the binding force of the mortar to the ceramic tile is increased, meanwhile, the binding agent is alkaline, the interface on the back face of the ceramic tile can be slightly reacted, the roughness of the interface is increased, and the binding agent can adhere and cure the mortar interface more easily. A modified retarder is added, so that the coagulation speed of the mortar is slowed down, the mortar does not react with groups outside modified waste tire particles and a binder, meanwhile, the modified retarder has the effect of a plastic stabilizer, the anti-sagging property of the mortar is improved, the micro-reaction inside the mortar is stabilized, and the bonding capacity of the mortar and a matrix interface is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a dry-mixed ceramic brick bonding mortar. Background technique [0002] Nowadays, with the rapid development of industry and economy, the amount of waste tires is increasing every year, and the resulting solid waste pollution has become a serious environmental problem. According to statistics, in 2015, the number of waste tires produced in my country was about 150 million, and it increased rapidly at a rate of 8% to 10%. A large number of waste tires accumulate for a long time. On the one hand, a large amount of land resources are wasted to form "black pollution", and at the same time, it is easy to cause fires and cause "secondary pollution". Due to the special composition and structure of waste tires in the process of processing, the fire caused is difficult to control, and a large amount of toxic pollutants and smoke are produced, causing serious pollution to the environment...
