Problems solved by technology

However, the oil extension ability of styrene-ethylene branched polydiene-styrene triblock copolymer is not good, and the hardness and flexural modulus of the material cannot be reduced by a large amount of oil extension. The disadvantages of high hardness, poor mechanical strength and flexibility, and the inability to prepare large-thickness coil products
In addition, the preparation method of styrene-ethylene branched polydiene-styrene triblock copolymer is difficult, there is no localization, and the price is expensive, which makes it impossible to apply in large quantities

Abstract

The invention discloses a high-molecular environment-friendly elastic sound insulation material. The material comprises the following components in parts by weight: 10-20 parts of an allyl elastomer,5-15 parts of a styrene elastomer, 40-120 parts of a filler, 1-15 parts of a plasticizer and 2-10 parts of an assistant. The high-molecular environment-friendly elastic sound insulation material has the advantages of high density, high strength, high flexibility, high sound insulation performance, high environment friendliness, excellent high and low temperature resistance and the like. The invention further discloses a preparation method of the high-molecular environment-friendly elastic sound insulation material. The method comprises the following steps: premixing the styrene elastomer and the plasticizer in a dispersion machine, adding the obtained mixture and the allyl elastomer into an internal mixer, carrying out melting and uniform mixing, adding other components, carrying out melting, conveying the plasticized materials into a single-screw extruder, and carrying out extrusion, squeezing, stretching and shaping to obtain the high-molecular environment-friendly elastic sound insulation material. The preparation method is simple to operate, low in cost and suitable for industrial promotion.

Description

technical field [0001] The invention belongs to the technical field of sound-insulating materials, and in particular relates to a high-density, high-strength, high-flexibility, high-sound-insulating polymer environment-friendly elastic sound-insulating material and a preparation method thereof. Background technique [0002] The existing polymer sound insulation materials mainly use polyvinyl chloride resin (PVC) as the base material, adding a large amount of phthalic acid plasticizers, antimony trioxide and inorganic fillers to achieve flexible materials, high flame retardancy and high density. Performance requirements, widely used in rail transit, construction and other fields. Due to the need to add a large amount of plasticizers and antimony trioxide and other flame retardants to this material, the environmental protection is poor, and it cannot meet the EU RoSH environmental protection directive. The toxicity of smoke and smoke is very high, which limits the application...
