The performance indicators of the prepared damping glue are: solid content 34%; glue viscosity 5.5Pa·S (25°C); T-peel strength 26.2N / cm; tensile shear strength 7.4MPa; tanδ≥0.20 temperature range: -10~75℃.

Embodiment 2

[0032] Masticate 132g of nitrile 26 on a twin-roller for 5-10 minutes, then add 14g of zinc oxide and knead until the Vickers plasticity is 0.25 for later use; then masticate 120g of nitrile 40 on the twin-roller until the Vickers plasticity is 0.35 for subsequent use; then add nitrile 26 mixing material and nitrile 40 mixing material together into stirring 1000g butyl acetate, 600g dimethyl carbonate and stir until fully dissolved; then add 80g phenolic resin, 20g chlorinated polystyrene Stir ethylene, 28g chlorinated polypropylene, 186g epoxy resin, 36g curing agent and 7g 1,1-bis(tert-butylperoxy)cyclohexane until completely dissolved and form a uniform viscous liquid to obtain the damping plate Use normal temperature damping glue. The performance indicators of the prepared damping glue are: solid content: 28%; glue viscosity: 3.8Pa·S (25°C); T-peel strength: 27.3N / cm; tensile shear strength: 7.7MPa; tanδ≥ 0.20 temperature range: -10~75℃.

Embodiment 3

[0034]Masticate 120g of nitrile 26 on a two-roller machine for 5-10 minutes, then add 14g of zinc oxide and knead until the Vickers plasticity is 0.25 for later use; then masticate 120g of nitrile 40 on a two-roller until the Vickers plasticity is 0.35 for subsequent use; then nitrile 26 joins the mixing material and nitrile 40 mixing material together in stirring 800g butyl acetate, 800gMIBK and stirs until fully dissolved; then add 80g phenolic resin, 20g chlorinated polyethylene and 28g chlorine Thin polypropylene, 160g of bisphenol A epoxy resin (E-51) and 40g of bisphenol A benzoxazine, 31g of DDS and 7g of 1,1-bis(tert-butylperoxy)cyclohexane were stirred until completely dissolved The normal temperature damping glue for the vibration damping plate can be obtained in the form of a uniform viscous liquid. The performance indicators of the prepared damping glue are: solid content: 28%; glue viscosity: 4.5Pa·S (25°C); T-peel strength: 29.3N / cm; tensile shear strength: 9.5MP...

Abstract

The invention discloses damping glue for a vibration reducing plate and a preparation method thereof. The component formula of the damping glue is as follows: 3 to 10 parts of nitrile-butadiene rubber 26 (NBR 26), 5 to 7 parts of nitrile-butadiene rubber 40 (NBR 40), 2 to 4 parts of additive, 2 to 12 parts of epoxy resin (EP), 1 to 5 parts of phenol formaldehyde resin (PF), 1 to 2 parts of curingagent, 0.3 to 0.5 part of peroxide, 0.5 to 1 part of zinc oxide, and 65 to 75 parts of solvent. The preparation process of the damping glue is as follows: the NBR 26 is firstly plasticated on a double-roll machine for 5 to 10 minutes, and then the zinc oxide is added and mixed with the NBR26 until the Williams plasticity is between 0.2 and 0.3; then the NBR40 is plasticated on the double-roll machine until the Williams plasticity is between 0.3 and 0.4; the mixed material is added to the solvent being stirred and stirred until being completely dissolved; and afterwards, the PF, the additive, the EP or a compound thereof, the curing agent and the peroxide are stirred until being completely dissolved into an evenly thick liquid, and then the normal-temperature damping glue for the vibrationreducing plate can be acquired. The main performances of the manufactured damping glue are as follows: the solid content is 25 to 35 percent; the glue solution viscosity (measured by a rotational viscometer) is 3.5 to 7 Pa.S (25 DEG C); the T-peel strength is larger than 20N/cm; the tensile shear strength is larger than 7MPa; tangent Delta is larger than or equal to 0.20; and the temperature range is minus 10 DEG C to 75 DEG C.

Description

technical field [0001] The invention relates to a damping glue for a vibration-damping steel plate and a preparation method thereof, in particular to a damping glue for a vibration-damping plate with a wide damping temperature range and a high damping factor in the use temperature range and a preparation method thereof. Background technique [0002] The vibration-damping steel plate made of steel plate and polymer material is a new type of material that has developed rapidly at home and abroad in recent years. It utilizes the high damping characteristics of polymer materials and has a significant effect of damping vibration and noise. An ideal product to replace pure metal sheets. Since the 1990s, the United States, Japan, Europe and other developed countries have done a lot of work in the research and application of vibration damping steel plates, and have been widely used in aerospace, automobile, machinery and other industries, and have received good economic benefits. ....
