Problems solved by technology

The first form has the following problems: 1. The thermal conductivity of traditional mortar is generally greater than 0.9W / m.k. The thermal insulation effect of the system can only rely on the thermal insulation board itself. The mortar hardly contributes to the thermal insulation performance of the system, which indirectly reduces the Insulation effect of insulation cladding
2. Since the current insulation board technology mostly uses strip sticking or point sticking, the insulation structure of this cavity method reduces the wind pressure resistance of the system; at the same time, the surface of the current insulation board uses mortar and grid cloth as an anti-crack protection layer , the specific gravity of the selected mortar is often greater than 1.8g / cm 3 , this insulation system increases the load of the insulation coating itself, so the current insulation board system has hidden dangers of low safety; 3. Not long after the insulation coating is completed, the thermal insulation board is affected by the temperature. Thermal expansion and contraction stress, or the use of poor-quality plastering mortar, the cracks on the surface of the system are prone to cracks, and it is easy to be invaded by rainwater, thereby reducing the thermal insulation effect of the system; When the method of strengthening heat preservation is adopted, galvanized metal mesh is often used to strengthen the insulation coating. The disadvantage of this method is that the galvanized metal mesh is easily corroded in the alkaline environment of cement, and the galvanized metal mesh and The mortar is gradually detached and loses its due strengthening effect
5. The bonding strength is low. When the external negative wind pressure is large or the surface load is large, there will be unsafe hidden dangers in the thermal insulation coating. At the same time, the bonding mortar has certain requirements for the treatment of the thermal insulation board interface. The interface treatment puts forward higher requirements, such as brushing the interface agent, or grinding the surface, which increases the construction procedure and complexity
6. Metal corner guards are used at the external corners of the building. The metal corner guards are easily corroded by the alkaline environment, resulting in hollowing and cracking of the external corners of the building.
The problems of the second form are: 1. Waste of raw materials
When spraying polyurethane outdoors, it is greatly affected by wind and temperature, and about 30% of the polyurethane material will be wasted
2. The flatness of the thermal insulation layer after spraying is poor, and the surface of the thermal insulation layer needs to be leveled before the construction of the next process can be carried out, which increases the thickness of the thermal insulation layer, increases the load of the system, and increases the construction cost. process

Abstract

The inner deposited and outer hung heat insulating coating for wall includes a moistureproof interface layer, a heat insulating board, a light protecting mortar layer with netted cloth and a surface decoration layer successively attached to the outer surface of the outer wall, and has heat insulating blocks and deposited foamed polyurethane layer between the heat insulating board and the outer wall. The making process includes the following steps: adhering heat insulating blocks to the wall; adhering the heat insulating board to the blocks to form cavity in between; depositing foamed polyurethane material to the cavity; smearing the light protecting mortar layer while sandwiching netted cloth; and forming the surface decoration layer. The present invention has raised heat insulating effect, strengthened heat insulating layer strength, high safety coefficient, saving in time and material.

Description

technical field [0001] The invention also relates to a method for making a thermal insulation coating for a wall, in particular to a method for manufacturing a thermal insulation coating for an internally cast and externally hung wall. Background technique [0002] In the current wall insulation industry, there are common thermal insulation forms with better effects, one is a thin plaster system for bonding mortar and pasting insulation boards, and the other is a thick plaster system for spraying polyurethane. The construction procedure of the thermal insulation board thin plastering system is: apply the bonding mortar on the thermal insulation board, then bond the thermal insulation board to the wall, apply anti-cracking mortar on the surface of the board after the bonding is firm, and embed the grid in the mortar at the same time Cloth reinforcement, and then make a finishing layer on the surface of the anti-cracking mortar. The construction procedure of spraying polyuret...
