Detailed introduction

(邱小姐:一九九六) Interior sheet extruder, automotive sheet production line (Ms. Qiu: 1996)

Sound insulation, noise reduction, vibration damping interior sheet, sheet extrusion production line
Automotive sound insulation materials are materials designed for vehicle noise. The main automotive sound insulation materials are butyl rubber, which is an environmentally friendly damping sheet, rubber and plastic, and EVA / EPDM sheet.
1 The causes of noise and vibration of automobiles and their requirements for anti-vibration damping materials. As a walking machine, automobiles must emit noise and vibration. Generally, the sounds we hear mainly come from engines, gearboxes, wind, tires and moving parts. Impact friction and so on. One part is transmitted through the air; the other part is transmitted through the car body after being vibrated. It can be seen that to eliminate or reduce noise, one is to eliminate or reduce the source of noise; the other is to try to prevent the transmission and vibration of noise. The thermoplastic sheet described in this article belongs to the latter. The sound-proof materials can be roughly divided into three types: sound-proof materials, sound-absorbing materials and shock-proof damping materials. According to the actual car inspection, to reduce the noise of the car to the standard state, each car must use several kilograms to dozens of kilograms of anti-vibration and sound insulation materials. In order not to increase the vehicle's own weight too much, these materials must have a damping effect, and the specific gravity must not be too large. The lower the cost, the better. Most recently developed are multifunctional composite materials. Thermoplastic shock-proof and sound-insulating materials mainly play a role of sound insulation and damping. 2 Raw materials and process status of products Although there are many basic materials for thermoplastic shock-proof and heat-insulating sheets, due to the popularity and fashion of automobile products, all manufacturers still use low-price asphalt. shou 选,因为它具有耐热性好的重要特点。此外,%"号石油沥青也是不可缺少的牌号之一。 Among the many grades of bitumen, ## petroleum asphalt is selected by various companies because it has the important characteristic of good heat resistance. In addition,% "petroleum asphalt is one of the indispensable grades. As we all know, although asphalt has many advantages, its fatal disadvantage is that its performance is too sensitive to temperature. Turning asphalt into a material that does not flow when exposed to heat and does not crack when it is cold is a research goal that science and technology workers are diligently seeking. There are many types of plasticizers for asphalt. Due to cost considerations, we do not use regular plasticizers, but use cheaper materials such as recycled tread rubber and motor oil. Due to the development of science and technology, thermoplastic elastomers have been widely marketed in recent years, which has brought more space for asphalt modification. Such as polyolefin elastomer, polystyrene elastomer, etc., are good materials modified by asphalt. Mechanical oil is also an optional plasticizer for asphalt, and it is also useful to regenerate engine oil to reduce costs. Another important component of shock-absorbing and damping materials is the filler, because it can not only improve the material performance, but also further reduce the cost. There are many types of filling materials that can be used as shock-absorbing damping materials. For example, according to the basic properties of the material, it can be divided into two categories: organic and inorganic; if it is based on the geometry of the material, it can be divided into four categories: powder, flake, granular and fiber. Specific examples are as follows: inorganic materials include wollastonite powder, asbestos powder, talc powder, sepiolite powder, graphite powder, mica powder, light calcium powder, etc .; organic materials include resin powder, recycled rubber powder, starch, etc .; flake materials include graphite. Powder, mica powder, vermiculite powder, etc .; fibrous materials include asbestos, wollastonite, and ground cotton fibers. In addition, anti-vibration damping materials are often filled with some tackifiers, lubricants, etc. Common types are calcium stearate.
