Abstract: A wall to be insulated is shown generally at 200. Applied to the wall 200 is a layer of insulating material 210, and on top of the insulating mixture is a layer of skimmed plaster 230. The thickness of the cumulative layers of insulator and skimmed plaster is represented by T'. Insulating material 210 has a thickness of less than 25 mm, more preferably a thickness of less than 4-8mm. The insulating material layer 210 is a mixture of cork granules, aerogel and binder. The cork granules comprise natural cork with particle size of 0.5-2mm in diameter. The aerogel may have an average particle size of 100-3500 µm. Preferably, the aerogel may have an average particle size of 500- 3500 µm. Even more preferably, the aerogel may have an average particle size of 1000-3500 µm. The binder may be a vapour permeable acrylic emulsion.

Abstract: A two-component curing composition for metal surface treatment, a method for mounting a film on a metal surface, and a surface structure are provided in the present invention. The two-component curing composition comprises: 15-35 wt% of a liquid epoxy resin; 20-35 wt% of a curing agent for epoxy resin; 5-15 wt% of a diluent; 10-25 wt% of a weight reducing agent; and 5-20 wt% of a flame retardant; wherein the two-component curing composition comprises a part A and a part B, the part A comprising the liquid epoxy resin, the part B comprising the curing agent for epoxy resin, and the diluent, the weight reducing agent and the flame retardant are present in one or both of the part A and the part B. The two-component curing composition for metal surface treatment has good open time and surface drying time when applied, and has a very high bonding strength to the metal surface to be treated and aging resistance. By means of the use of the composition, convenient, simple, and quick mounting of a film on the metal surface (e.g., a surface of a vehicle body) can be realized.
