Preparation method of cracking-resistance and maintenance-free plastering mortar, product and construction method thereof

Abstract

The invention discloses a preparation method of a cracking-resistance and maintenance-free plastering mortar, which comprises the following steps of: (1) preparing raw materials; (2) feeding; and (3) stirring and mixing, so as to prepare the improved plastering mortar. The invention also discloses a product prepared by using the preparation method and a construction method of the product. The method provided in the invention has the advantages of simple preparation process, easiness in implementation and high production efficiency. The product provided in the invention has the advantages of reasonable formulation design, high strength, good workability, easy construction, better stretching and bonding strength, difficulty in cracking, generation of no dusting or hollowing, less maintenance or no maintenance, and the maintenance cost is effectively reduced. The construction method provided by the invention has the advantages of simple process, easiness in implementation and good plastering effect, the construction period is shortened, the construction efficiency is effectively improved and the construction method is beneficial to wide generalization and application.

Description

technical field [0001] The invention belongs to the field of plastering mortar, and in particular relates to a preparation method of anti-cracking and maintenance-free plastering mortar, a product thereof, and a construction method. Background technique [0002] The amount of plastering mortar in construction engineering is second only to concrete, and it is the most important part of construction, and it also accounts for the largest proportion of dry-mixed mortar. [0003] A good plastering mortar can protect the building and the wall. It can resist the erosion of the building by wind, rain, snow and other natural environments, and improve the durability of the building. [0004] The importance of plastering mortar has not been fully valued. The status quo of the traditional plastering mortar currently used is: [0005] 1. The mix ratio is simple, cement, lime, river sand, water, no need to consider other aspects of performance to introduce functional additives; [0006]...

AI Technical Summary

Problems solved by technology

[0005] 1. The mix ratio is simple, cement, lime, river sand, water, no need to consider other aspects of performance to introduce functional additives;

[0006] 2. The quality of raw materials is not stable. Because of insufficient attention to plastering mortar, some poor-quality cement is often used as plastering mortar; river sand with large mud content is also frequently used; as for the fineness of river sand, it is basically There is no requirement, just use it;

[0007] 3. The mixing equipment is primitive and simple, the mortar is not evenly mixed, and the quality fluctuates greatly

[0008] 4. For the sake of speed, the thickness of one-time plastering is too large

[0009] 5. After construction, the maintenance is not in place or not maintained

[0010] Due to the above reasons, the traditional mortar produced has poor workability, low construction efficiency, insufficient water retention capacity, fast drying and fast curing, and the mortar is prone to problems such as looseness, cracking, powdering, hollowing, etc., and cannot protect the wall well.
