Problems solved by technology

At present, in order to obtain higher flame retardancy, it is usually necessary to add a large amount of flame retardant fillers, which is not conducive to the damping and self-adhesive properties of damping materials.
[0006] In summary, the existing preparation methods of butyl rubber-based damping materials are difficult to satisfy the damping performance, flame retardancy and self-adhesive performance required by damping rubber at the same time.

Abstract

The invention discloses a self-adhesive flame retardant butyl rubber damping material and a preparation method thereof. The rubber material is prepared from the following components in parts by weight: 100 parts of butyl rubber, 50 to 400 parts of damping and adhesion aids, 50 to 400 parts of tackifying resin, 100 to 800 parts of compound flame retardant and 0 to 1000 parts of filler. The self-adhesive and flame retardant butyl rubber damping material obtained by the invention has the characteristics of wide-temperature-range damping, high damping peak, and excellent self-adhesive property and flame retardant property. According to the self-adhesive flame retardant butyl rubber damping material and the preparation method thereof, the self-adhesive flame retardant butyl rubber damping material is prepared by using a simple blending method through the proper formula adjustment; the method has the advantages of simple and convenient method, low cost, simple industrialization, high production efficiency and good industrial application prospect.

Description

technical field [0001] The invention relates to the preparation of a self-adhesive flame-retardant butyl rubber-based damping material, which belongs to the technical field of flame-retardant damping materials. . Background technique [0002] While the rapid development of modern industry and transportation has brought convenience to people, problems such as vibration and noise have become more and more serious, which has brought serious harm to people's health and social production. Vibration and noise pollution has become one of the four major environmental pollution in the world. Damping material is a material that can convert mechanical vibration energy or sound energy into heat energy and dissipate other forms of energy to play a shock-absorbing effect. It is widely used in mechanical equipment, construction engineering, transportation and other fields. [0003] Due to its unique viscoelasticity, polymer materials have a significant damping effect compared with metal ...
