Gypsum-based building mortar and preparation method thereof

Abstract

The invention relates to the technical field of building mortar, in particular to gypsum-based building mortar and a preparation method thereof. The mortar comprises an aggregate A, an auxiliary material B, an emulsion C and a flavoring liquid D. Gypsum is selected as a main processing raw material and is prepared into the aggregate A, so that the cohesiveness and strength of the finished mortar are effectively improved; various kinds of soil are selected to be processed into an auxiliary material B, the auxiliary material B is mixed into the aggregate, large gaps exist between molecules of the auxiliary material, effective components of the aggregate, the emulsified liquid and the flavoring liquid can be effectively wrapped, the cohesiveness of the finished mortar is improved, and meanwhile because of addition of soil auxiliary materials, the fluidity of the finished mortar is effectively improved; furthermore, the emulsion C is added, so that the finished product mortar is smoother,but the cohesiveness is very strong, and the finished product mortar is not easy to adhere to a bricklaying tool; finally, by adding the flavoring liquid D, the smell of the finished product mortar iseffectively improved, and the original pungent smell is weakened, so that the finished product mortar has light grass fragrance, and meets building requirements of people.

Description

Technical field [0001] The invention relates to the technical field of construction mortar, in particular to a construction mortar based on gypsum and a preparation method thereof. Background technique [0002] Mortar is a binding material used in building bricks. It is made by adding water to a certain proportion of sand and cementing materials, such as cement, lime paste, clay, etc. It is also called mortar or mortar. The commonly used mortars are cement mortar, mixed mortar, or cement-lime mortar, lime mortar and clay mortar. [0003] However, with the development of the construction industry, the past construction mortar can no longer meet the needs of the industry, and people increasingly need high-quality construction mortar; and gypsum, which has strong cohesiveness, is more environmentally friendly than lime, and is more in line with people Demand. Summary of the invention [0004] Based on the above, the present invention provides a gypsum-based construction mortar and di...
