Problems solved by technology

But its sound insulation effect is poor
In addition, there are more electrical components in automobiles nowadays, and there are hidden dangers in the safety of circuits. Information about spontaneous combustion of automobiles is common in the news, and automobile interiors that use a large number of engineering plastics become fuel when spontaneous combustion occurs, accelerating or intensifying combustion, which is extremely harmful to personnel.

The invention discloses a sound-absorbing and heat-insulating automotive interior material and a preparation method thereof. The material comprises, by weight, 30-50 parts of polyurethane resin, 40-60 parts of ethylene propylene diene monomer, 20-40 parts of epoxy modified organic silicon resin, 4-6 parts of polypropylene, 10-20 parts of hexagonal boron nitride, 20-25 parts of porous powder quartz, 22-26 parts of an inorganic flame retardant, 5-8 parts of carbon nanocone, 1-3 parts of a plasticizer and 80-120 parts of deionized water. The sound-absorbing and heat-insulating automotive interior material provided by the invention is prepared from natural environment-friendly materials, is odorless, pollution-free and non-irritant, has good flame-retardant and heat-insulating properties, has good mechanical structure performance, and is environment-friendly, safe and practical.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a sound-absorbing and heat-insulating automotive interior material and a preparation method thereof. Background technique [0002] In recent years, my country's auto industry has developed rapidly, and the number of small family cars has been increasing year by year. With the increase in the number and frequency of use of cars and the changes in people's consumption patterns, people not only value the appearance of the car when buying a car, Instead, it pays more attention to the interior environment of the vehicle. Therefore, high-quality interior materials must be used in the production and assembly of automobiles in order to meet the increasingly stringent requirements of consumers, especially in terms of sound insulation and heat insulation. [0003] Existing car interior materials seldom consider sound insulation and heat insulation functions. Now the noise polluti...
