The invention discloses an
adhesive special for
viscoelastic damping, having a formulation composed of:
neoprene-240, duprene B-30, magnesia,
zinc oxide, resins (giving specific names of the resins) and
carbon black, N-phenyl-alpha-
naphthylamine (an anti-aging agent A). A manufacturing method thereof comprises the steps: using a mill, adding enough cooling water, regulating the roller spacing to the minimum thereof, putting in crude rubbers, plasticating the rubbers over 10 times, widening the roller spacing to 2-4 mm, adding a variety of accessory ingredients, plasticating inversely for three times, regulating the roller spacing to about 1mm, packing 3-6 triangle bags, putting 1-2mm heavy-gage rubber sheets for
backup; preventing the rubber sheets from
adhesive bonding,
cutting the rubber sheets into rubber strips and immersing the rubber strips in a
solvent for over 24 hours, stirring the
solvent until sufficient
dissolution thereof is realized, wherein, the concentration of the solution is 20-25%; acquiring the
adhesive special for
viscoelastic damping. The body materials have similar
solubility parameters and high
cohesive strength, are resistant to
seawater, oil and
flame and possess high mutual
viscosity and
adhesion strength with the adhered materials like a steel plate, besides, the initial
viscosity of the adhesive is excellent.
