Definitions

  • the present invention relates to a flocking belt for use on a car seal, and more particularly to a flocking belt capable of eliminating the abnormal sound of glass rise and fall of an automobile seal.
  • Acoustic anomalies are a common type of automotive mechanical failure. When such a fault occurs, the driver of the car can hear a dull or sharp sound from the engine, or other parts can be rattled due to abnormal friction. This abnormal sound sometimes occurs. A certain frequency or interval alternates or does not appear to occur intermittently.
  • various parts such as the guide groove of the automobile glass, the door frame of the automobile, the trunk of the automobile, or the sunroof of the automobile are all abnormal.
  • the general solution is to use plastic or rubber sealing strips or sponge strips to fill the gap to reduce the abnormal noise of the car.
  • reduction does not mean elimination. This dynamic noise still occurs during the driving of the car, and the problem cannot be solved better with the seal or sponge strip alone.
  • the flocking layer itself does not have good adhesion and wear resistance, so that it can not resist the vibration of the window glass of the car in the process of contact with the window glass of the automobile, resulting in the window glass of the car being lifted and lowered.
  • the vibration process frictional sliding occurs with the flocked pile layer, and abnormal noise is generated.
  • Electrostatic flocking is the physical property of the same-sex repulsive anisotropy, which causes the fluff to carry a negative charge.
  • the object that needs flocking is placed under zero potential or grounding conditions, and the fluff is attracted by the flocked object with different potential.
  • the vertical acceleration accelerates to the surface of the flocked object. Since the flocked object is coated with the adhesive, the fluff is vertically adhered to the plant body, so the electrostatic flocking is a process that utilizes the natural characteristics of the electric charge.
  • a flocking belt capable of eliminating the abnormal sound of the glass of the automobile seal comprising a flocking film, a flocking glue, a fluff and a silicon fluororesin, and rolling the flocking glue on the flocking film at the place
  • the flocking glue is electrostatically inserted into the pile; the silicon fluororesin is sprayed on the pile.
  • the electrostatic flocking can make the fluff erected on the glue water, and the erected fluff can be completely sprayed with the silicon fluororesin.
  • the silicone resin has high adhesion, on the one hand, it can be firmly attached to the pile, on the other hand, it can be firmly attached to the glass; and because the silicone resin has high wear resistance, it can be lifted and lowered in the automobile glass. During the process, the silicone resin adhered to the glass can withstand the internal intermolecular friction between the glass and the silicone resin.
  • a silicone resin for waterborne wood lacquer which is an anionic emulsion of pure acrylate, special material and core-core copolymerization of normal temperature crosslinking monomer. It has excellent adhesion and wear resistance of polyurethane resin, and has excellent resistance to hot and cold water, excellent weather resistance, chemical resistance, and good pigment wettability and mechanical stability. At the same time, the disadvantages of easy aging of the polyurethane resin and the poor compatibility of the acrylic and polyurethane mixed emulsions and poor chemical stability are avoided.
