Description of the invention (f) < Technical field > The present invention is a composite blanket material, especially for automobile interior use. It has light weight, good sound absorption, high strength, antibacterial, anti-ultraviolet, etc. Characteristics of composite blankets. < Existing technology > Car interior is like a person's intrinsic beauty. The quality it displays is related to the car's distinguished level. Of course, the car interior is not only focused on the beauty of the car. It may be functional. For the purpose, such as the interior carpet of a car, in addition to creating a home-like comfort, the carpet at the place where the fire is suspected (inclined floor under the dashboard, also known as dash / LWR) must have fire and sound absorption effects. The entire car carpet needs to have sound absorption characteristics. Traditionally, car interior carpets, which are generally mass-produced at low prices, use a type of recycled cotton called fe 1 t. Such recycled cotton does have a cost consideration. It can meet the demand for the interior carpet materials of affordable Volkswagen, but the fe I t recycled cotton has poor sound absorption and cannot provide the excellent quiet effect of the cabin. Because it cannot be integrally formed when the carpet is formed, subsequent bonding is very labor-intensive, and The use of too much glue to make the car room produce an unpleasant odor, coupled with the excessive weight makes it difficult to install and position, and its texture is breathable Poor and inadequate strength, so it is easy to cause wet mold smell in the car memory under long-term use, and the trampled carpet is also not easy to recover and cause depression, these are all fe 1 t recycled cotton cannot be used as high-grade car carpet materials s reason. Due to the above-mentioned shortcomings of f e 1 t recycled cotton, the industry has published paper sizes that apply Chinese National Standard (CNS) A4 specifications (210X 297 mm).

A7 B7 V. Description of the invention (the) A PU material foamed with MD IB ase isocyanate is issued. The biggest characteristic of this PU material is the basic The commercial sound absorption rate is low and the conventional fe 1 t recycled cotton jacket is more effective at intermediate frequencies. Therefore, it has a significant effect on the quietness of the cabin that is valued by high-end cars. However, this PU foam also has a number of Disadvantages, such as the need to use sheet chlorocarbon as a foaming agent in the production process, so it is easy to cause damage to the beauty layer: Moreover, the weight of this PU material is heavier than fe1t recycled cotton, and the breathability is also Poor, because it is difficult to be ideal in terms of installation, positioning and use: especially the excessive weight of PU itself, which is undoubtedly worse for the overweight phenomenon caused by continuous addition of today's cars: even if it has more fe 1 t recycled cotton Carpets made for better strength are less likely to sag, but their high manufacturing costs and excessive weight are probably the only ones that can withstand high-volume cars. < Solutions > Looking at the blanket materials currently used in automobiles, whether it is low-cost fe 1 t recycled cotton or high-priced MDI Ba se isocyanate foamed PU materials, they are more or less There are few inapplicable shortcomings, so it is urgent to find a good alternative material: this material must have sound absorption properties even beyond the PU material foamed by MDI Base isocyanate, and its strength is better than fe 1 t Recycled cotton, MDI Base isocyanate PU foam is high, the most important thing is that its reset is lower than MD IB ase isocyanate PU foam; in other words, the material must have good sound absorption, light weight Quantitative and high-strength properties, and the composite blanket of the present invention is a material that meets the above-mentioned functional characteristics: it is made of TDI Base isocyanate, polyol, antibacterial agent, flame retardant, UV-resistant agent and water foaming agent. This paper · size applies to China National Forest Standards (CNS) A4 specification (210X297 mm) (Please read the notes on the back before filling this page) Order A 7 _B7_ V. Description of the invention (3)) After mixing and foaming separately Mix and mix and pour into a mold to make Combined with p VC or carpet, and after high temperature reaction and high temperature drying, it is made into a P VC board or carpet and TDI Base isocyanate foamed PU positive sound-absorbing cotton. A molded composite: the composite A piece of PET-like cotton is bonded under the foaming PU forward sound-absorbing cotton; the composite material thus constructed has a foaming PU forward sound-absorbing cotton with excellent forward incidence sound absorption at low and intermediate frequencies, so that The compartment built by this material has a high level of tranquility: Furthermore, the PU forward sound-absorbing cotton foamed by TDI Base isocyanate has the same weight as the MDI Base isocyanate. The foamed PU material is light, so the interior carpet made from this material is easier to construct when installed and positioned, and does not cause excessive increase in vehicle weight: In addition, the foamed PU is attached to the bottom of the sound-absorbing cotton or separated into the pad. The P ET susceptible cotton, with its horizontal mesh structure, provides sufficient structural strength of the upper PU positive sound-absorbing cotton, so that it will not cause depression and springback under long-term use: In addition, the present invention utilizes TDI Base isocyanate foaming PU light sound-absorbing cotton The setting characteristics, combined with the strength reinforced by PET cotton, make the car interior carpet formed from this in addition to good sound absorption, light weight and high strength, and other intangible economic benefits, and its convenience after light weight The effects of assembling and reducing the weight of the automobile also tangibly reduce the manufacturing and use costs of the present invention.

This can be seen from the speculative data in Tables 1 and 2. Table 1 is the forward sound absorption of foamed PU cotton made of MDI Base, TDI Base, and TM isocyanate. Table 2 shows the sound absorption coefficients of foamed PU cotton of MDI B a ^ e 'TDI Base and TM isocyanate at various frequencies. It can be seen from the test pieces of Table 1 and I 2 Under the same thickness, the paper size of TM is in accordance with the Chinese National Standard (CNS) A4 specification.

Description of the invention (G) The weight of the test piece is only 60% of the weight of the MD IB ase test piece, that is, at the same thickness, the foamed PU cotton of TDI Base isocyanate is more than that of MDI Base isocyanate. Foamed PU cotton is light, and the data shows that PU cotton foamed with TD IB ase isocyanate can indeed improve the car caused by PU cotton made with MD IB ase isocyanate foam. The weight is too heavy and the placement and positioning difficulties caused by overweight are buried; in fact, the foamed PU positive sound-absorbing cotton made of TDI Ba se isocyanate can even be more Weighing half of the foamed PU cotton shrinking to MDI Base isocyanate to obtain a more lightweight performance; furthermore, from the analysis of the sound absorption of the two, TDI Base isocyanate The sound absorption rate of foamed PU forward sound-absorbing cotton at low and medium frequencies is not affected by its light weight, and can still reach the sound absorption rate level of foamed PU cotton such as MDI Base isocyanate * even by the table It can be seen in 1 that its low and medium frequency sound absorption rate stability is also better than MDI Base: it is a foamed PU positive sound absorption cotton using TDI Base isocyanate, in addition to being lightweight , Its low- and medium-frequency sound absorption rate is no less than that of MDI Base isocyanate foamed PU cotton, which proves that it can indeed be used as a blanket for car interiors, so that the car room has excellent quietness degree. Please refer to the second chart to improve the carpet sag phenomenon caused by the lack of strength of conventional PU 1 t recycled cotton and MDI B ase isocyanate foamed PU cotton: Therefore, the present invention This problem can be solved by PET fiber cotton attached or cushioned to the bottom of the sound-absorbing cotton; this kind of PET woven cotton (also known as PDF sound insulation cotton) is a kind of paper with horizontal net paper and applicable Chinese national standard (CNS ) A4 specification (2 丨 0X297mm) (Please read the note on the back before filling in this page) Order A 7 ___________ 5.
