Easy plaster and additive thereof

Abstract

The invention discloses easy plaster and an additive thereof, and relates to the technical field of building materials, and the easy plaster comprises the following components: ash cement, modified emulsified asphalt powder, modified polyacrylamide, cordierite powder, capillary crystalline master batch, magnesium lithium silicate, coarse whiting, 50-80-mesh mullite sand, 70-140-mesh sintered sand, a water reducing agent and an early strength agent. According to the invention, the easy plaster is subjected to a polymer modification technology and an asphalt modification technology, proper functional fillers and additives are selected, technical improvement is carried out aiming at the defects of various easy plaster products, and the prepared finished product has the following comprehensive characteristics: 1) the easy plaster has the effects of impermeability, bonding, water resistance, leakage stoppage and the like; 2) the flexible performance is excellent, the influence of deformation, settlement and the like can be endured, and cracking is avoided; 3) the shrinkage is low, no shrinkage crack is generated after construction, and the quality is stable; (4) the bonding strength is high, and the anti-sliding performance is good; 5) the weather resistance and the aging resistance are good; and 6) the unit area consumption is less, and the method is more environment-friendly and economical.

Description

Technical field [0001] The present invention relates to the field of building materials, in particular to a kind of glue mud and additives thereof. Background [0002] Yijiao mud generally refers to the polymer yi glue mud, polymer yi glue mud is an advanced cementitious polymer composite material, composed of dispersible latex powder and a certain proportion of ordinary Portland cement, fine sand and functional additives mixed and mixed and blended and prepared. It is a good substitute for C2 type tile glue and polymer cement waterproof mortar. [0003] Yi glue mud because of its large adhesion, good impermeability, waterproof and environmental protection and other properties, as an excellent waterproof material, it is mainly used in industrial and civil building waterproof and veneer brick (or natural finish stone) pasting project, and adhesion and waterproof performance is its main consideration of the performance factors, its excellent waterproof and bonding performance, in t...

AI Technical Summary

Problems solved by technology

As a result, there are many types of Yijiao products on the market, and the product quality is uneven. The main product defects are: 1) As a rigid waterproof material, its flexibility is poor, and it is difficult to resist the settlement of buildings, especially new buildings. Deformation, leading to cracking, waterproof failure; 2) high shrinkage, resulting in large deformation in the drying process after construction, cracks and other defects; 3) low bonding strength and easy to slip, especially when bonding facing bricks or natural When facing stone materials, there is a risk of falling bricks; 4) The opening time is short, and the construction needs to be completed in a short period of time, otherwise it will easily lead to insufficient bonding strength after the drying time, which will cause certain troubles for workers; 5) Durability Poor aging performance, especially when used in water-immersed parts and parts with obvious alternation of cold and hot, after a certain period of time, the performance will drop sharply, which is prone to quality problems

6) The amount of beneficial cement per unit area is large, the cost is high, and it is uneconomical
