Abstract

The present invention provides a self-adhesive and environment-friendly damping rubber plate. The self-adhesive and environment-friendly damping rubber plate comprises a metal plate, reinforcing ribs, release paper and damping rubber, wherein the damping rubber comprises the following raw materials in parts by weight: 15-70 parts of modified rubber, 1-5 parts of pigments, 10-30 parts of a flame-retardant agent and 15-45 parts of a damping filler. The present invention provides a preparation method of the self-adhesive and environment-friendly damping rubber plate at the same time. The method comprises the steps of: adding raw materials, preparing the damping rubber, coating the damping rubber, adding the reinforcing ribs, pressing upwards and downwards, and paving a layer of release paper. The self-adhesive and environment-friendly damping rubber plate has the beneficial effects the self-adhesive and environment-friendly damping rubber plate has a high damping value in different temperature ranges, is of an enhanced structure, and is environment-friendly, free of pollution to the environment and good in flame-retardant property.

Description

Technical field [0001] The invention relates to the field of damping materials, in particular to a self-adhesive environmentally friendly damping rubber sheet and a preparation method thereof. Background technique [0002] With the development of modern science and technology, people have higher and higher requirements for working and living environments, and vibration and noise control have increasingly become a problem that needs to be solved urgently. Because the viscoelastic damping material has high damping characteristics and can suppress vibration and noise in a relatively wide frequency band, it can be used for vibration and noise reduction of mechanical components, such as automobiles, ships, locomotives, etc. [0003] Viscoelastic damping material is an active noise reduction material, most of which are polymer materials such as rubber. The technical principle of vibration reduction and noise reduction is to bond viscoelastic damping material on the surface of the vibrati...
