Description
Technical Field
The invention relates to a building energy-saving heat preservation agent and a preparation method thereof, in particular to an external wall external heat preservation adhesive for building energy conservation and a preparation method thereof.
Background
Today, the continuous growth of social demands and the increasing level of consumption are that the energy shortage problem becomes a great problem in recent years for restricting the continuous coordinated development of the economy and society of China, and even affecting the quality of life of people. The building industry is always a high energy consumption industry, on one hand, energy is short, the situation is severe, on the other hand, building energy consumption is extremely wasted, building energy conservation is difficult, and the building energy conservation is the weakest link in the construction of an conservation-oriented society.
The heat preservation of the outer wall is a key link of building energy conservation. Strengthen and attach importance to the wall body heat preservation work, strive to reduce energy consumption, improve the comfort level of living environment, and is a good thing for the national and civil benefits.
The external heat preservation of the outer wall of the building is a new building energy-saving technology appointed and popularized by the country in recent years, and has the advantage of incomparable internal heat preservation. The external thermal insulation of the outer wall is generally to paste a thermal insulation board on the surface of the treated external wall base layer, then smear corresponding anti-cracking mortar, and lay a reinforcing net at the same time. In order to enhance the viscosity of the adhesive, the interface mortar needs to be painted on the wall surface of the base layer once. The external wall external heat insulation system is more, and the most is a polystyrene foam board externally hung glass fiber grid cloth reinforced polymer mortar. The key point of success and failure is that the polyphenyl board and wall surface bonding material is used for selecting the polymer mortar cover surface material with crack resistance and water resistance requirements on the polyphenyl board surface.
However, the existing materials and processes of the common external wall external heat insulation system have a plurality of defects, and common quality problems are as follows: (1) The heat-insulating board is adhered to the outer side surface of the foundation wall, a cavity is formed between the heat-insulating board and the foundation wall easily, the adhered surface is small and can not withstand the extrusion and pulling of positive and negative wind pressure to the heat-insulating wall, the cracking of the heat-insulating layer is easily caused, and the heat-insulating board can be locally lifted off under extreme conditions so as to be difficult to repair. (2) The plastic-coated glass fiber mesh cloth is used as a reinforcing rib, the bonding force between the plastic-coated glass fiber mesh cloth and mortar is insufficient, an isolation layer is formed, and the waterproof protection facing layer is easy to fall off. (3) The glass fiber mesh cloth is directly paved on the heat insulation board, so that the anti-cracking effect is not achieved, the isolation effect is formed, and the protection layer falls off. (4) The local adhesion fails to squeeze the adjacent parts, and the parts or large areas are formed to fall off under the action of wind force and gravity. (5) The stress changes of frequent thermal expansion and contraction are easy to crack under the influence of the temperature changes of seasons and day and night, and especially the tablet falls off in severe cold areas under the influence of water inflow and freeze thawing between layers. In a word, if the materials are selected and applied improperly, the external wall external heat insulation system can have faults such as severe cracking.
In addition, the adhesive for external wall building heat preservation sold in the market at present is mainly in a dry powder state and needs to be mixed and prepared on site. Some manufacturers provide liquid adhesives, but users need to mix auxiliary agents such as cement, filler, additives and the like according to the requirements when using the adhesives, and the operation of the adhesives is complex. And when the external thermal insulation system of the outer wall adopts bonding mortar (also called polymer thermal insulation board bonding mortar) as a bonding agent for bonding the thermal insulation boards, the phenomenon of poor thermal insulation effect is common, the adhesion capability is low, the cost is high, and the quality and the safety of the external thermal insulation engineering of the outer wall of the building are greatly and negatively influenced.
