Embodiment Construction

[0025] A special adhesive for viscoelastic damping, its formula consists of:

[0026] Neoprene - 240:20 parts

[0027] Neoprene B-30: 80 parts

[0028] Magnesium oxide: 4 parts

[0029] Zinc oxide: 5 parts

[0030] Resin: 20 parts

[0031] Carbon black: 15 parts

[0032] N-phenyl-α-naphthylamine (antiaging agent A): 1 part

[0033] like figure 1 The special adhesive for viscoelastic damping shown, its manufacturing method:

[0034] Equipment used: open mill, turn on the cooling water of the open mill, adjust the roller distance to the minimum, put in raw rubber, thin pass plasticizing more than 10 times, widen the roller distance to 2-4mm, add various compounding agents, Reverse refining 3 times, adjust the roller distance to about 1mm, make 3-6 triangle bags, and lay down 1-2mm thick film for backup; to prevent the film from sticking.

[0035] Dissolution: Cut the film into strips, soak in solvent for more than 24 hours, stir until fully dissolved, the solution concen...

Abstract

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.

Description

technical field [0001] The invention belongs to rubber adhesives, in particular to a special adhesive for viscoelastic damping and a construction method. Background technique [0002] The existing viscoelastic damping adhesive has poor performance: the initial tack of the adhesive is poor. The bonding strength of the adhesive cannot be guaranteed, and the bonding and peeling strength with the damping rubber sheet is low, and the construction is complicated. Contents of the invention [0003] The invention provides a special adhesive for viscoelastic damping and a construction method. It achieves similar dissolution parameters to the main material of the viscoelastic damping rubber sheet, high cohesive strength, seawater resistance, oil resistance, flame resistance, etc. It has good mutual adhesion with bonded materials such as steel plates, high bonding strength, and good initial tack performance. . Ensure that the adhesive has high bonding strength, good initial tack a...
