heat-curing reactive systems

Abstract

The present invention relates to thermosetting formulations comprising (a) a triglyceride fraction whose fatty acid distribution contains at least 5% by weight, especially at least 60% by weight, of one or more omega-3 fatty acids and / or one or more omega-6 fatty acids; (b) at least one vulcanizing agent selected from the group consisting of (b1) sulfur, (b2) peroxide vulcanizing agents, (b3) quinones and / or quinonedioximes, and / or (b4) disulfides nitrobenzene; and (c) at least one inorganic filler.

Description

technical field [0001] The present application relates to thermosetting formulations based on triglyceride moieties containing omega-3 fatty acids and / or omega-3 fatty acids, to a process for preparing said formulations, and also to said formulations as acoustic damping adhesives, sealants or Use of coating compositions. Background technique [0002] Metal sheets with very thin walls are commonly used in the production of automobiles, machines and devices to reduce their weight. Mechanically moving parts or running motors inevitably cause these thin-walled metal plates to vibrate at frequencies usually within the audible range of the human ear. These vibrations are propagated through the entire vehicle, machine or installation in the form of solid-borne sound, which can be released into the air at a distance as disturbing noise. Therefore, in order to reduce the sound emission and eliminate the structure-borne sound, the thin-walled metal sheets used, especially in the man...

Problems solved by technology

However, these systems have disadvantages, especially for industrial applications with high production volumes; because water cannot be removed from the sprayed coating quickly enough due to the large coating thickness

Another disadvantage of these conventional methods of sound attenuation is that these materials are used for the single purpose of sound attenuation
