Embodiment 1
[0026] refer to figure 1 , a new type of building energy-saving wall, from the outside to the inside are the base layer 1, the insulation layer 2, the plastering layer 3, and the finish layer 4, the base layer 1 and the insulation layer 2 are connected by an adhesive, so A reinforced mesh cloth 5 is provided between the plastering layer 3 and the facing layer 4, and the thermal insulation material of the thermal insulation layer 2 includes crop straws, adhesives, waterproofing agents, preservatives, and flame retardants. The adhesive is isocyanate resin, the waterproofing agent is paraffin wax emulsion; the preservative is borate powder; the flame retardant is magnesium hydroxide.
Embodiment 2
[0027] Embodiment 2 The construction method of the new building energy-saving wall body
[0028] Such as figure 2 As shown, a new type of building energy-saving wall and its construction method, including the following steps:
[0029] Step 1. Apply adhesive on the base layer and paste the insulation material to form the insulation layer;
[0030] Step 2. Add a layer of plastering layer on the insulation layer, and lay glass reinforced mesh cloth on the plastering layer;
[0031] Step 3. Make a finishing layer on the reinforced mesh cloth, and the finishing layer adopts paint and facing bricks.
[0032] Such as figure 1 Shown, the preparation method of the thermal insulation material of described thermal insulation layer is:
[0033] Step 1: Clean and remove weeds: prevent the mixed weeds from easily rotting in a humid environment, which will affect the quality of straw bricks;
[0034] Step 2: cutting: cutting the cleaned straw with a cutting machine to obtain straw fibe...
Embodiment 3
[0040] The performance test of embodiment 3 energy-saving wall body
[0041] The fire protection grade of the material can reach F90, the shrinkage rate is generally 0.02mm / m, the sound insulation is 50dB, and the thermal conductivity is ≤0.05W·(mk) -1 , Compared with brick walls, it can reduce the weight by 75-80%, and reduce the cost by 30%.
