Description
Technical Field

Background
The automatic door of the automobile is usually provided with an ultrasonic radar in a metal door plate, ultrasonic signals are emitted through an ultrasonic transducer, the metal door plate is excited and generates high-frequency resonance signals, and then the high-frequency resonance signals are received by a receiver, so that the automatic opening effect of the automobile door is achieved.
Since other obstacles around the vehicle body are excited and generate high-frequency resonance signals when the ultrasonic transducer transmits ultrasonic signals, the receiver receives interference signals. In order to improve the interference of an obstacle with an ultrasonic radar, a damping sheet is generally attached between the ultrasonic radar and a door panel to suppress a high-frequency resonance signal of the obstacle.

Although the high-density flame-retardant damping film can effectively inhibit the high-frequency resonance signals of the obstacle, the high-density flame-retardant damping film is easy to fall off from the metal door plate due to high density and heavy weight of the high-density flame-retardant damping film.

The isolation layer is release paper with the thickness of 0.1mm;
the high-density butyl damping layer is self-made high-density butyl damping sizing material with the thickness of 2.9mm and the density of 2.7g/cm 3 ；
The limiting layer is an O-state aluminum plate with the thickness of 0.1mm.
In the comparative example, the total weight of the high-density butyl damping rubber material is 300kg, and the components and parts by weight thereof are shown in the following table:

A commercially available butyl damping shim is different from example 1 in that the density of the butyl damping compound in the commercially available butyl damping shim is 1.56 g/cm 3 The modified butyl rubber is replaced by the oat petrochemical 1751 butyl rubber (with Mooney viscosity of 51) with the same weight, the polymethylstyrene-co-styrene resin is replaced by the Isoman Piccotac 9095 with the same weight, the filler is formed by mixing calcium carbonate and talcum powder according to the weight ratio of 1:1, and the addition amount of the PP/NBR thermoplastic vulcanized rubber is 0.
Comparative example 3
A butyl damping fin differs from example 1 in that in the butyl damping compound used to prepare the butyl damping layer, an equal weight of Yanshan petrochemical 1751 butyl rubber (Mooney viscosity 51) is used in place of the modified butyl rubber.
Comparative example 4
A butyl damping fin is different from example 1 in that in the preparation of butyl damping compound of butyl damping layer, equal weight PP/EPDM thermoplastic vulcanizate, ekkimen Mobil Santoprene TPV 8211-35 is used instead of PP/NBR thermoplastic vulcanizate.
Comparative example 5
A butyl damping fin differs from example 1 in that in the butyl damping compound used to prepare the butyl damping layer, an equal weight of Islaman Piccotac 9095 was used in place of the polymethylstyrene-co-styrene resin.
The density of the butyl damping compound obtained in comparative examples 3 to 5 of the present invention was measured, and the measurement result showed that the density of the butyl damping compound obtained in comparative examples 3 to 5 was 1.63 g/cm 3 。
The butyl damping sheets obtained in example 1 and comparative examples 1 to 5 of the present invention were tested for weight reduction, peel force, loss factor, combustion performance, ELV, formaldehyde content and radar gain, and the test results are shown in the following table:
as can be seen from the data analysis of the above table, example 1 has a relative 38.1% weight reduction over comparative example 1, but no clutter was detected by the radar at both the-40℃and 5 ℃. Therefore, the butyl damping sheet has the characteristics of light weight, easiness in bonding with a metal door plate and radar clutter suppression in a high-low temperature range. The reason for this is probably that in the total raw material for the preparation of the butyl damping compound, the methyl styrene segment in Exxpro 3035 rubber is partially compatible with the polymethylstyrene-co-styrene resin Kristalex 5140, but the polymethylstyrene-co-styrene resin will still exist as microspheres resulting from microscopic phase separation, forming a physical cross-link which may be the main reason for the ability of example 1 to suppress high frequency vibration energy at a high temperature of 95 ℃. The ability of the butyl damper to suppress high frequency vibrations at-40℃is related to the fact that the rubber segments of the modified butyl rubber and the PP/NBR thermoplastic vulcanizate remain entangled in the low temperature region, and is expected to be related to the absorption of high frequency vibrations by benzene rings and acrylonitrile and other groups in their molecular structures.
Example 1 significantly increased peel force at 180 ℃ baking relative to comparative example 2, no clutter was detected by radar in the temperature range-40 ℃ to 95 ℃. Therefore, in the total raw materials for preparing the butyl damping rubber, the butyl damping rubber prepared by mixing the modified butyl rubber, the PP/NBR thermoplastic vulcanized rubber, the polymethyl styrene-co-styrene resin, the barium sulfate and other raw materials can improve the radar clutter suppression capability and the high-temperature baking resistance capability of the finally obtained butyl damping sheet in a high-low temperature range. Although the 20℃loss factor in comparative example 2 reached 0.25, clutter still occurred in the radar at normal temperature. The reason for this analysis may be that the presence of the NBR dispersed phase which has been crosslinked in the PP/NBR thermoplastic vulcanizate is due to the physical interaction of the methylstyrene segment and the polymethylstyrene-co-styrene resin in the modified butyl rubber, and that the ferroferric oxide powder has a high density and has a partial ferromagnetism. Wherein, when the ferroferric oxide high-density filler is filled to the same density, the volume ratio is relatively small, and the stripping adhesion of the sizing material is better. The natural ferroferric oxide powder has a favorable effect of inhibiting high-frequency vibration and can be related to the natural ferroferric oxide powder which has certain magnetism and thus has certain electromagnetic effect under the high-frequency vibration. Therefore, the butyl damping rubber material prepared from the modified butyl rubber, the PP/NBR thermoplastic vulcanized rubber, the ferroferric oxide powder and the polymethyl styrene-co-styrene resin is used as the butyl damping layer, high-frequency vibration can be effectively restrained in a temperature range of-40 ℃ to 95 ℃, the baking resistance is outstanding, the bonding effect of the butyl damping sheet and the metal door plate is improved, and interference of an obstacle on an ultrasonic radar is improved.
Example 1 significantly increased peel force at 180 ℃ baking relative to comparative example 3, no clutter was detected by radar in the temperature range of 85 ℃ to 95 ℃. Example 1 no clutter was detected by the radar at both-40 ℃ and-30 ℃ relative to comparative example 4. Example 1 compared to comparative example 4, no clutter was detected by the radar at both 85 ℃ and 95 ℃. Therefore, the butyl damping layer prepared from the modified butyl rubber, the PP/NBR thermoplastic vulcanized rubber and the polymethyl styrene-co-styrene resin can improve the radar clutter suppression capability and the high-temperature baking resistance of the finally obtained butyl damping sheet in a high-low temperature range.
