Description
Technical Field
The invention belongs to the field of high molecular polymer materials, and particularly relates to a flame-retardant antibacterial polymer alloy material as well as a preparation method and application thereof.
Background
In recent years, with the improvement of the living standard of people and the enhancement of the health consciousness, the demand for various antibacterial material products, in which the antibacterial plastic products account for a large proportion, has been increasing, and various living products, including refrigerators, air conditioners, various food containers, packaging bags, washing machines, toy products, dust collectors, and the like, all use various thermoplastic antibacterial plastics.
PBT, the chemical name of which is polybutylene terephthalate, has developed rapidly since its industrial production. Many factories in China use PBT plastics. As one of five engineering plastics, PBT is popular among people due to the characteristics of good physical and mechanical properties, good electrical properties, easy molding and processing and the like. The PBT resin can be applied to various potentiometer products matched with industries in various fields such as aerospace, communication, post and telecommunications, military industry, energy, traffic, household appliances and instruments. With the development of the automobile industry, the electronic industry and the electrical industry, the development of PBT has wide prospects. PBT has good processing fluidity and impact resistance, but mechanical properties and heat resistance are not ideal enough, so that the application of the PBT is limited. However, the warpage of the PBT plastic product is prominent, which affects the correct use of PBT, and the PBT resin is easy to crystallize, which is essentially difficult to avoid warpage.
Polycarbonate (PC) is a high molecular polymer with the advantages of excellent high heat resistance, high impact resistance, glossiness, good transparency, good dimensional stability and the like, but the PC has the defects of easy stress cracking, poor processing fluidity, poor solvent resistance, notch sensitivity and the like, so that the application of the PC in the field of engineering plastics is limited.
The PC and PBT resin are blended to prepare the alloy, so that the performances of the PC and the PBT resin are complementary. The PC/PBT alloy has the excellent performances of the PC/PBT alloy, on one hand, the heat resistance and the mechanical property of the PBT can be improved, and on the other hand, the melt strength of the PC can be reduced, the processability is improved, and the stress sensitivity of a product is reduced. Therefore, the PC/PBT alloy is widely applied to the fields of automobiles, machinery, household appliances, communication tools, office equipment and the like.
Polycarbonate is not easy to burn, can reach V-2 grade in UL-94 vertical burning test, but due to the flammability of PBT, after being blended with PBT resin, the flame retardant property of PC/PBT alloy is reduced, and can not be graded (NR, No Rating) in UL-94 test, and the polycarbonate can be ensured to be applied to the fields of automobiles, electronics, electricity, machinery and the like with higher flame retardant requirements only through flame retardant modification.
When the PC/PBT alloy material is prepared, a toughening auxiliary agent of the material is added in the traditional method, the mutual melting of the material is enhanced, the toughness of the material is improved, and the defects of the material and the material are complemented, particularly, the transesterification of the material is easy to occur between the PC/PBT material, the physical properties of the material are greatly influenced, and after the material is subjected to flame retardant modification, a compatilizer and a toughening agent are additionally added to improve the interaction between the auxiliary agent and a base material, so that the toughness of the alloy is improved. The patent CN104530634A, the patent CN107057322A and the patent CN107325518A all solve the contradiction between the flame retardance and the toughness of the material by the method. The strength, toughness and functions of the application guide material of the PC/PBT material are very important, the application of the flame-retardant and antibacterial alloy material in the application of electric appliances can be greatly widened, and the quality of life of people in daily life and working environment can be further improved. In addition, the halogen-free flame retardant, the material compatilizer and the low-temperature flexibilizer are expensive, and the development of the materials is also limited.
The novel broad-spectrum, efficient, nontoxic and nonirritating antibacterial product developed in the nineties of the last century is widely applied to the fields of textile, agriculture, food, sanitation and the like. The preparation of the antibacterial plastic is mainly realized by adding a certain amount of antibacterial agent in the granulation process of the antibacterial plastic. The antibacterial agents are of various types, mainly including inorganic antibacterial agents and organic antibacterial agents, and guanidine salt polymer antibacterial agents are commonly used. Currently, the variety of guanidine salt polymers mainly includes polyhexamethylene (bis) guanidine hydrochloride, polyhexamethylene (bis) guanidine propionate, polyhexamethylene (bis) guanidine stearate, and other inorganic or organic salts of polyhexamethylene (bis) guanidine, polyoxyethylene guanidine, and the like. Guanidine salt polymers are mostly used in the form of aqueous solutions because of their excellent solubility in water, and are used as bactericides for water treatment in japanese patent publication No. JP05209195A, US patent publication No. US4891423A, and chinese patent publication No. CN 101156586A. In addition, the guanidine salt polymer also has good thermal stability and high thermal decomposition temperature up to 280 ℃, so that the guanidine salt polymer can be used as an additive to be applied to plastic, fiber and rubber products to obtain an antibacterial product. However, most guanidinium polymers are very water soluble, making powder samples difficult, limiting their use in plastic, rubber, and fiber applications. Chinese patent publication No. CN101037503A discloses a method for preparing a powdered guanidine salt polymer product, which separates a guanidine salt polymer from an aqueous solution through an ion separation exchange membrane to prepare a powder sample; however, the method for preparing the guanidine salt polymer powder has the disadvantages of harsh conditions and complicated process.

TABLE 1 results of antibacterial experiments of example 1 and comparative examples 1 to 2
From the above comparison results, it was demonstrated that the guanidine salt complex antibacterial agent still has a good antibacterial effect even after the amount of the compound antibacterial agent is reduced, and the water resistance after poaching is reduced, but the antibacterial effect of the antibacterial plastic before and after poaching (comparative examples 1 and 2) is lower than the antibacterial effect of the antibacterial liquid mixing aids prepared by the liquid antibacterial aids OIT and BBIT (example 1).
Table 2 comparison of the performances of the flame-retardant PC/PBT products prepared in examples 1-6 and comparative examples 1-3
As can be seen from Table 2, compared with the alloy materials of the embodiments 1 to 6 of the invention, the toughening efficiency of the traditional toughening method in the comparative examples 1 to 3 is low, and in addition, the flame retardant property of the PC/PBT composition is reduced due to the flammability of the material phase in the comparative example 2, and the UL-94 test is V-2 grade. And only adding the halogen-free flame retardant (comparative example 1) greatly affects the toughness of the alloy, and compared with the PC/ABS alloy (comparative example 3), the impact performance at normal temperature and low temperature is respectively reduced by 75.8% and 47.4%. Therefore, the addition of the liquid antibacterial auxiliary agent and the flame retardant not only can generate great influence on the interaction among the components of the material, but also can greatly reduce the impact property of the PC/PBT alloy. In addition, in comparative examples 1 to 2, the flame retardant has poor dispersion difficulty due to poor interaction between the flame retardant and the matrix resin, thereby reducing the flame retardant efficiency of the flame retardant.
The examples 1-5 show that the halogen-free flame-retardant PC/PBT alloy prepared by the invention has good comprehensive performance, and the PC/PBT alloy with both flame retardant performance and high impact performance is prepared by the formula design and the addition of the halogen-free flame retardant, the single-component compatibilizer and the toughener. The PC/PBT alloy material can reach V-0 grade in UL94 vertical combustion test, the self-extinguishing time is less than 10s, and the better rigidity, the impact property and especially the low-temperature impact property of the PC/PBT alloy are maintainedCan reach 58kJ m-2Is obviously higher than that of the PC/PBT alloy (19kJ m) with flame retardant modification of a comparative example-2). In a comparative example 3, the HTCTP flame retardant additive with a good flame retardant market is selected, the material performance and the flame retardant effect are excellent through testing performance, and in the using process and the material preparation process, the heat distortion temperature of the flame retardant additive is low, so that great difficulty is brought to the use of the flame retardant additive, and the experiment generated waste material is difficult for people to continue the experiment.
In the preparation of the flame-retardant antibacterial alloy material, the selected flame-retardant auxiliary agent, the antibacterial effect and the specific preparation process have decisive effects on the performance of the material and the application result of the material. In the comparative example 4, a common double-screw processing technology is adopted, a liquid pump is not adopted to add a mixture of an antibacterial flame-retardant auxiliary agent, different flame retardants and antibacterial agents are adopted to mix, and in the material feeding section part, due to the fact that different auxiliary agents often cause a bridging phenomenon to material blanking, raw materials are prevented from entering an extruder, the material can be obviously bonded in the processing process, and processing and use performances of the material are affected. In the comparative example 4, the flame-retardant antibacterial liquid is not added by a liquid pump, the flame-retardant antibacterial material is prepared by adopting the traditional mixing process, and the liquid is directly flowed out of a feeder in an experiment due to the large addition amount of the liquid in sample preparation, so that the prepared material is inaccurate in adding the liquid auxiliary agent, the processing process is influenced, and the flame-retardant, antibacterial and physical properties of the material are obviously reduced. In the embodiments 1 to 5, the components in the material obtained by the preparation process provided by the invention are uniformly mixed, and the material has better mechanical properties.
