Mortar water retention and heat preservation polymer additive, and preparation method and equipment

Abstract

The invention discloses a mortar water retention and heat preservation polymer additive which is composed of the following components in parts by weight. 45-55 parts of a water-retaining agent, 1.5 to2.5 parts of a thickening time control enhancer; 6-7 parts of a water reducing agent, 0.2 to 0.7 part of an air entraining agent; 81 to 89 parts of deionized water; 1-3 parts of an aggregate, 0.1 to0.2 part of a defoaming agent; 0.2 to 0.3 part of an accelerating agent; and 1.5-2.5 parts of waterproof agent. The invention further discloses a preparation method and equipment of the mortar water retention and heat preservation polymer additive. The key point is that through synchronous improvement of the mortar water retention and heat preservation polymer additive, the preparation method andthe equipment, the mortar construction quality is improved with ensured mortar dispersity, the mortar is more stable, the strength can be ensured, the additive can be completely stirred through the preparation equipment, the stirring time is shortened, the working efficiency is effectively increased, the generalization performance is good, the working time is substantially shortened, the industrial processing can be achieved, and the effect is excellent.

Description

technical field [0001] The invention relates to the technical field of mortar additive manufacturing, in particular to a mortar water-retaining and heat-retaining polymer additive, a preparation method and equipment. Background technique [0002] With the development of society, the single function of mortar can no longer meet the needs of construction. At present, cement is used as the main cementing material to meet the requirements of energy-saving, soil-saving, and waste-reducing new wall masonry materials for wall reform. It mainly includes lime sand bricks, autoclaved aerated concrete blocks, hollow blocks, concrete hollow bricks, etc. The above blocks are used in various building constructions, and the walls made of the above-mentioned new wall masonry materials, It is called a new type of block wall, but this type of block has higher requirements on the workability, cohesive force and water retention of mortar. At the same time, the water retention and heat preservat...

Problems solved by technology

A good air-entraining agent can introduce as many as 1 billion air bubbles into the concrete, and the pore diameter is mostly 0.05-0.2mm, generally in the shape of a discontinuous sealed ball, evenly distributed, and good stability, which can significantly improve the frost resistance of concrete. However, in the mortar, the more air bubbles, the smaller the pressure bearing capacity of the mortar. Therefore, it is impossible to make the mortar have better pressure resistance, and the use of building types is more limited, and it cannot be more Good enough to meet the use of buildings. In the existing additive mixing device, its mixing efficiency cannot be effectively improved, and the effect of industrialization promotion is not good enough to meet the needs of social development.
