Adhesive sheet for noise and shock absorption, and saw blade making use of it, and manufacturing methods therefor
An adhesive sheet for noise and shock absorption and a saw blade making use of it and manufacturing methods therefor for use in joining components of a cutting or grinding apparatus to generate vibrations and noises such as a cutting saw machine for a grinding or cutting material such as brick, concrete, granite, marble, etc. The adhesive sheet according to the present invention is composed of a resin adhesive such as denaturalized epoxy resin, phenol resin, rubber, or compound composition thereof etc., and a noise and shock absorption material infiltrated with the resin adhesive, and fabricated by infiltrating the noise and shock absorption material such as non-woven fabric, paper, or textiles with the resin adhesive such as denaturalized epoxy resin, phenol resin, rubber, or compound composition thereof etc., and drying the infiltrated noise and shock absorption material at a predetermined temperature for several minutes and hardening it by half.The saw blade for use in the cutting or grinding apparatus of the present invention is composed of a wheel body for connecting with a shaft of an electric motor having upper and lower wheel portions, and an adhesive sheet layer including a noise and shock absorption material disposed between upper and lower wheel portions of the wheel body, and fabricated by positioning the adhesive sheet for noise and shock absorption between upper and lower wheel portions of the wheel body, and hardening wheel portions and the adhesive sheet therebetween at a predetermined temperature and pressure for given times.
