Home decoration cement additive and application thereof

Abstract

The invention provides a home decoration cement additive and application thereof. The home decoration cement additive is prepared from the following raw materials in percentage by mass: 15 to 35% of air entraining component, 0.1 to 5% of water-retention thickening component, 0.1 to 5% of fluidity and bonding power improving component, 1 to 10% of retarder component, 0.1 to 5% of antibacterial andfresh-keeping component, and the balance of water. The application is characterized in that the home decoration cement additive can be applied into home decoration the cement; the cement additive is used in a liquid state, the mixing amount is equal to 0.015 to 0.03% of the home decoration cement by mass, and the cement additive is added into a mill together with materials in the powder milling process of the home decoration cement. The cement additive has the advantages that the water-retention property is good, the delaminating degree and viscosity loss of mortar are small, the bonding poweris strong, the setting time is adjustable, the construction workability is good, and the like; the cement additive can be widely applied to cement plastering, brick building, bedding, tile sticking and the like.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a cement admixture for home decoration and its application. Background technique [0002] At this stage and even for a long period of time, my country will be the world's largest cement producer and consumer, but at present, the domestic cement production capacity is seriously overcapacitated, and the cement market competition is becoming increasingly fierce and chaotic. Therefore, the classification of cement products and the needs of user groups It has become a consensus to "de-homogenize" cement products to get rid of market difficulties and improve product competitiveness. Most of the bagged cement in the civilian market is used for interior decoration. Due to its demand, stable price and short payment cycle, it has always been an important source of profit for cement companies. Lafarge Cement, Italian Fuping Cement, Huaxin Cement, China Resources Cement, ...

Problems solved by technology

The decoration of civil self-built houses is a non-continuous operation. The amount of mortar used is small, it is inconvenient to store, and it cannot be purchased directly from the mixing station. Obviously, it does not meet the conditions for using ready-mixed mortar. The common practice is to directly purchase ordinary cement and sand (separately Add mortar king, rubber powder, or other functional materials) and mix water to make mortar. Without scientific proportioning and accurate measurement, the ease of construction of this mortar is often not satisfactory
