Accompanying drawing explanation
Fig. 1 is material profile schematic diagram of the present utility model.
In figure: 1---antistatic backing; 2---damping layer; 3---substrate layer.
The specific embodiment
As seen from Figure 1, the utility model is bonded by three layer construction, comprises antistatic backing 1 above, middle damping layer 2, substrate layer below 3.
Antistatic backing 1: this layer, in outermost layer, consists of antistatic sheet material, this antistatic material sheet resistance value is 10
4Ω to 10
9between Ω, for damping layer 2, possesses larger modulus of elasticity.Any one among common use antistatic poly (methyl methacrylate) plate, antistatic polyvinyl chloride panel (anti-static PVC plate), anti-static ceramic plate, antistatic polycarbonate plate (antistatic PC plate), antistatic PET plate (antistatic polyester sheet), Antistatic Nylon plate, antistatic inorganic-organic hybrid plate class.The sheet material that material that antistatic backing is used general reference is processed through antistatic, comprise the finished product sheet material made through antistatic technique and common sheet material later stage through antistatic auxiliary agent or anti-static coatings, material spray, be coated with, the compound sheet material of means such as sticky, pressure.
Damping layer 2: being lifelong viscoplasticity polymer damping material,, containing organic solvent, is not environmentally friendly environmental protection sound insulation adhesive.Damping layer 2 has two functions, and the one, the bonding and obstruct as the gluing between antistatic backing 1 and substrate layer 3, the 2nd, play damping action.Damping layer is lifelong viscoplasticity polymer damping material, is a kind of aqueous, environmental protective sound insulation adhesive before solidifying, and directly antistatic backing and substrate layer is bonded together.Versatility based on environment for use, its glass transition temperature is lower, is generally (but being not limited to) subzero below 20 ℃.
Substrate layer 3: form constrained damping structure with antistatic backing 1 together with damping layer 2, possess certain mechanical property and larger surface density sheet material.Conventionally use among gypsum plank, glass magnesium plate, calcium silicate board, metal sheet, ceramic wafer, cement fibrolite plate etc. any one.The material that substrate layer is used can be selected according to the required physical and chemical index of reality, soundproof effect etc. kind and the thickness of specified material.
As above three layer construction forms constrained damping structure, on anti-static ability, to be the material that uses of antistatic backing 1 require to require configuration with mechanics, fire prevention, moistureproof and waterproof, weather-proof etc. according to antistatic skin, and it is 10 that antistatic requires very strict occasion configuration surface resistance value
