Polycarbonate PC is widely used general plastic, has excellent comprehensive performance and molding processing type, is relatively low in price, has a leading position in the plastic, and is widely applied to daily life. The glass fiber system is added to effectively make up the performance defect of the polycarbonate, thereby further reducing the cost.
With the current trend of light weight of automobiles, the glass fiber reinforced polycarbonate system is increasingly applied to various parts of automobiles, such as front section frames, bumpers and the like. An increasing number of fiberglass-reinforced polycarbonate systems are entering automobiles, with another problem being odor and VOC. With the advent of the passenger car air internal quality standards policy, odor and VOCs have been a major hurdle around major host plants and even the general public. The interior of the automobile is a sealed environment, and the odor emitted by the parts and the volatile small molecular substances in the automobile can not be effectively and quickly discharged to the outside and can only be absorbed by the personnel in the automobile, so that a series of hidden dangers are brought. Science has shown that some substances in VOC can cause direct harm to human body and environment, for example, high content of VOC can cause damage to sensory nerves such as vision and hearing, even cause nervousness or depression after being in such environment for a long time; for another example, formaldehyde can irritate the pharynx and lungs of humans, causing dyspnea, headaches, chest tightness, and even emphysema. In the conventional solution, such as the solution described in CN201310308220.6, which uses nano zinc oxide and nano titanium dioxide to achieve low odor and low VOC by changing the addition amount of the mass ratio and vacuum extraction, although the ideal effect can be achieved, the price of nano zinc oxide and nano titanium dioxide is expensive, and the effect of achieving low odor and low VOC by adding these two additives is not feasible in the actual factory production, but only some small molecular substances with lower boiling points can be extracted by this method, and the rest substances with higher boiling points remain in the material and cannot be eradicated really; CN201010543461.5 also uses a similar solving method, and uses a compound deodorant to achieve the purposes of removing odor and low VOC, but the zinc ricinoleate is used as a leading deodorant to have a remarkable effect on removing sulfur micromolecules, and the effectiveness of aldones on other micromolecules such as benzene is still needed to be studied, so that the glass fiber reinforced polycarbonate which has the requirements of low odor and low VOC can not be really achieved.

TABLE 2 Performance test results for low odor glass fiber reinforced polycarbonate composites
From the performance tests of the examples and comparative examples shown in table 2, it can be seen that the odor and VOC content of the glass fiber reinforced polycarbonate system can be significantly improved without reducing the mechanical properties of the composite material by using the method of the present invention using the combination of two types of odor removing agents. In comparative example 6, experimental example 7, experimental example 8, comparative experimental example 1 and comparative example 1, it can be seen that in the composite system with the same mixture ratio, the odor grade of the composite material has a gradient change with the increase of the glass fiber content and the interfacial compatilizer content, the odor and VOC content can be effectively improved by adding the odor removing agent, after the odor removing agent is added, the odor grade of the composite material is increased from 4.0 to 3.3, and the TVOC content is reduced from 68.1 to 5.4, which is reduced by as much as 90%. And as can be seen from comparison of examples 4 and 5, the odor and VOC content of the composite material can be improved by the addition of the deodorant, and the mechanical properties of the composite material can be improved to a certain extent, because the polymeric deodorant is added, in the melt extrusion process, the deodorant can effectively polymerize free small molecules, and meanwhile, in the polymerization process, some interface compatilizer monomers which are not grafted participate in the grafting reaction, in combination with examples 7 and 8, the mechanical properties of the composite material are slightly improved by adding the polymeric deodorant, which proves that the addition of the polymeric deodorant does not negatively affect the composite material, but promotes the grafting of the compatilizer, and improves the mechanical properties of the composite material. Comparing experimental example 4, experimental example 5, comparative example 2 and comparative example 3, it can be seen that the addition of a single deodorant is not as effective as the use of two deodorants, because the use of a single deodorant cannot rapidly and completely remove small molecules, and the small molecules which cannot be removed remain in the material, so that the purposes of low odor and low VOC cannot be really achieved.
In summary, the low-odor glass fiber reinforced polycarbonate composite material described in the product achieves the effects of low odor and low VOC by adding two different types of odor removing agents on the basis of the traditional glass fiber reinforced system, not only can the requirements of low odor and low VOC be met in the low glass fiber filling, but also the odor and VOC value of the composite material are not much different from that of the low glass fiber content system in the high glass fiber filling. Meanwhile, under the condition of adding a certain amount of compatilizer, the mechanical property of the composite material can be improved by adding the polymeric deodorant, and the requirements of low odor and low VOC can be met.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
