Non-woven fabric-coated regenerated foam mixed sheet foot pad for sound insulation in automobiles and preparation method thereof

Abstract

The invention discloses a soundproof non-woven fabric wrapped regenerated foam hybrid sheet foot pad in a vehicle. The foot pad comprises a regenerated anti-flaming rubber and plastic foam sheet and an anti-flaming water-and-oil-repellent non-woven fabric. The anti-flaming water-and-oil-repellent non-woven fabric wraps out of the regenerated anti-flaming rubber and plastic foam sheet. The manufacturing method comprises: wrapping the anti-flaming water-and-oil-repellent non-woven fabric on the periphery of the regenerated anti-flaming rubber and plastic foam sheet; and heating cloth cover in a die to seal edges, and adhering sheet to the cloth cover, to complete manufacturing of the foot pad. Through the above method, the foot pad can recycle and reuse rubber and plastic foam to reduce environmental pollution and save resources and energy. The foot pad can reduce noise in a cab, and improves comfortableness for driving of a driver. The soundproof non-woven fabric wrapped regenerated foam hybrid sheet foot pad in a vehicle is harmless for people.

Description

technical field [0001] The invention relates to the field of automobile foot pads, in particular to a foot pad with a sound-insulating non-woven fabric in an automobile and a mixed sheet of regenerated foam and a preparation method thereof. Background technique [0002] my country is a big country of automobile manufacturing and consumption. my country's automobile scrapping standards have been revised many times. In May 2013, the Ministry of Commerce issued the "Regulations on Compulsory Scrapping Standards for Motor Vehicles", which made relevant regulations on the scrapping standards and years of various motor vehicles. defined. Generally speaking, the period of scrapping a car is 10-15 years, which is basically similar to the situation abroad. According to the experience of mature foreign markets, scrapped cars account for 5-7% of the total number of cars each year. We conservatively estimate the number of 154 million cars in 2014 based on 3%-5%. We estimate that the cur...

Problems solved by technology

[0003] At present, in order to reduce vibration and noise, the truck driver's cab adopts mechanical spring and air spring vibration reduction technology, which improves the ride comfort of the car, but the sound insulation effect of the driver's cab is poor, causing peculiar smell in the car, and some models have an unpleasant smell.

Dizziness and discomfort after driving for a long time, which affects the driving safety of the driver
