[0178] Preparation of two-part precursor compositions

[0179] Preparation of Part A

[0180] The JEFFAMINE D230 was set in a 2-1 mechanical mixer to which the EPIKOTE 232 was partially added and mixed at room temperature. Mixing was continued for 60 min at room temperature. The mixture was then heated to 80 °C and kept at this temperature for 60 min. Calcium nitrate and imidazole were added and mixed until both materials were completely dissolved. After adding ANCAMINE K54, the mixture was then cooled to room temperature. Add glass bubbles to the homogeneous mixture and mix for about 30 min. Then, the DUALITE microspheres were added and mixed for 15 min, resulting in a homogeneous white paste. The ingredients were used in the amounts indicated in Table 1.

[0181] Preparation of Part B

[0182] The base resin of the present invention (Part B) was prepared in a 2 liter mechanical mixer by combining the ingredients listed in Table 2. Water cooling was used to main...

Abstract

A curable precursor composition for preparing a vibration dampening composition having a density of less than 0.9 g / cm3 said precursor composition comprising (i) one or more rigid epoxy resin (ii) one or more flexible epoxy resin, (iii) a first set of hollow microspheres, (iv) a second set of hollow microspheres wherein the microspheres of the first set are different in composition from the microspheres of the second set and, a curing agent capable of cross-linking the rigid and flexible epoxy resins. Also provided are vibration dampening compositions obtainable from the precursor compositions and methods of preparing such vibration dampening compositions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from GB 0724378.5, filed 14 December 2007, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The compositions provided herein and methods of making those compositions relate to epoxy-based vibration damping compositions. Background technique [0004] Due to the environment in which multiple transport vehicles, electronic equipment, and machines are deployed or used, they are subject to noise and vibration. Such noise and vibration can indicate problems with their use or function, and can be annoying or harmful to users of such equipment or instruments. Therefore, there is a need to reduce the impact of such noise and vibration on instruments, equipment and their users. Noise and vibration are reduced by placing or fixing to these vehicles or equipment extension dampers in several patent applications. Stretch dampers are typically c...
