High-density, high-flame-retardation sound-insulation protection rubber and preparation method therefor

Abstract

The invention provides a preparation method for high-density, high-flame-retardation sound-insulation protection rubber and belongs to the rubber field. Firstly, ethylene propylene diene monomers are subjected to plastication and struck into roll films; then chlorinated polyethylene rubber is subjected to thin-passing plastication and struck into roll films; the plastified ethylene propylene diene monomers and the plastified chlorinated polyethylene rubber are placed in a banbury mixer and subjected to rubber combining; then zinc oxide, stearic acid, an activator, an antioxidant, an ultraviolet ray absorber, a fire retardant, an iron-containing compound, a softener and an inorganic filling material are added, mixing is carried out, a ram is lifted, the material is cleaned, mixing and discharging are carried out; sulphur and a vulcanization accelerator are added, thin-passing is carried out, the roll spacing is widened, and batch-off and storing are carried out; a sample is taken, and vulcanization performance test is carried out; the material after storing is subjected to plastication and batch-off, and molding is carried out by a calendar; drum-type vulcanization operation is carried out. The protection rubber is advantageous in that the protection rubber has characteristics of high density, high flame retardation, weather resistance, corrosion resistance and scraping prevention, especially the protection rubber meets the building fire protection B level standard and the processing performance of the material is good.

Description

technical field [0001] The invention belongs to a sound insulation and damping protection material and a preparation method, in particular to a high-density, high flame-retardant sound insulation protection rubber in the field of polymer materials and a preparation method. Background technique [0002] Sound insulation and noise reduction have attracted more and more attention from the society, and have been involved in various industries, especially the noise in the construction and locomotive industries has the greatest impact on people. Most of the traditional sound insulation materials in the building and locomotive industries have low density and cannot achieve a good sound insulation effect. The reason is that high-density sound insulation mats require high filling, high production costs, and are difficult to bend and difficult to construct. In order to change it, a large amount of plasticizer is added, and the precipitation of the plasticizer causes a safety hazard of...
