Flame-retardant high-damping thermoplastic elastomer material and preparation method thereof

Abstract

The present invention discloses a flame-retardant high-damping thermoplastic elastomer material, which comprises the following raw materials by weight: 30-70 parts of a polyamide resin, 60-100 parts of a thermoplastic elastomer, 40-60 parts of ethylene propylene diene monomer, 20-30 parts of an ionic liquid modified filler, 20-40 parts of a halogen-free flame retardant agent, 10-20 parts of a flame retardant aid, 7-10 parts of an anti-scorching agent, 3-6 parts of a vulcanizing agent, 5-15 parts of an active agent, and 2-5 parts of an accelerating agent. The invention further provides a preparation method of the flame-retardant high-damping thermoplastic elastomer material. According to the present invention, the polyamide resin, the thermoplastic elastomer and the ethylene propylene rubber are blended as the matrix, such that the tensile strength, the flexural modulus and the cross-linking polymerization degree of the product can meet a certain application range; by adding the ionic liquid modified filler, the damping coefficient is improved, the vibration reducing, the buffer or the vibration shielding are improved, and the effective action temperature zone of the damping performance of the rubber material is expanded; and by using the step-by-step heating processing process, the matching of the process and the formula is scientific and reasonable, the production cost is saved, and the industrial production is easily achieved.

Problems solved by technology

[0002] With the rapid development of science and technology and modern industry, problems related to vibration and noise pollution have become increasingly prominent. Frequent vibration and excessive noise will cause serious harm to human production and life: ① Vibration causes damage to building structures, such as automobiles Damage to bridges caused by resonance, damage to buildings caused by earthquakes and strong winds; ② Interfering with the normal operation of instruments and equipment, especially high-tech equipment, reducing their precision, increasing mechanical wear, and shortening their service life; ③ Noise caused by vibration , seriously pollute the environment and affect human health. At present, vibration and noise pollution has gradually become one of the three major environmental hazards, which can be compared with water and air pollution. Therefore, vibration reduction and noise reduction have developed into an urgent problem to be solved.

[0003] The use of damping materials and technologies is one of the most effective ways to reduce vibration and noise, and has attracted widespread attention. Among damping materials, elastic materials are the most widely used, but rubber elastomer damping materials have poor flame retardancy and damping temperature The range is narrow, which largely limits the application fields of rubber elastomer damping materials
