Description
Technical Field
The invention belongs to the field of polypropylene materials and preparation thereof, and particularly relates to a glass fiber reinforced PP/PA66 composite material for a water chamber of a new energy automobile and a preparation method thereof.
Background
The polypropylene material has the characteristics of low density, chemical resistance, excellent cost performance and the like, so that the polypropylene material has wide application in the fields of automobiles, household appliances, food, medical treatment, buildings and the like. But the low melting point limits the use of the alloy in high-temperature working environment, especially the use of the alloy around an automobile engine.
The nylon has very good mechanical strength and high melting point, and is very suitable for being used in the high-temperature working environment around the automobile engine. However, as the polymer chain has more polar groups, the phenomenon of alcoholysis is easy to occur, which leads to the problems of nylon molecular chain breakage, hydrogen bond destruction and mechanical property reduction.
The automobile radiator mainly plays a role of cooling an engine system in an automobile cooling system, a medium in a radiator water chamber is cooling liquid, and the main component of the radiator water chamber is ethylene glycol. The traditional radiator water chamber adopts glass fiber reinforced nylon, and the nylon is used as the water chamber and is in a high-temperature glycol soaking environment for a long time, so that the alcoholysis speed is accelerated, and the problem that the water chamber is easy to crack and lose efficacy in a pressure cycle key experiment is solved. At present, PA66-G30 is preferred according to the water chamber material, and the alcoholysis resistance is better than that of other nylon materials such as PA6 and the like. With the improvement of the heat management system technology and the revolutionary change of a power system of a new energy vehicle, the temperature of the whole radiator is obviously reduced compared with the prior art, the test temperature of the traditional high-temperature water chamber reaches 130 ℃, while the temperature of the low-temperature water chamber is only about 70-100 ℃, so that new opportunities are brought to the light weight of the water chamber, and more OEMs consider replacing glass fiber reinforced PA66 with short glass fiber reinforced PP materials. Due to the excellent ethylene glycol resistance of PP, the problem of alcoholysis would be completely solved if PP could replace PA66 material. However, as a water chamber part, one main problem of the replacement is temperature resistance, PP is difficult to completely meet the requirements of a high-temperature working environment of the water chamber, and rigidity indexes of the PP such as tensile strength, flexural modulus and the like under a high-temperature condition are much lower than those of the PP at normal temperature, so that the large-area popularization of the PP in the water chamber is limited.
Chinese patent CN111269490A discloses a high-rigidity flame-retardant polypropylene alloy material and a preparation method thereof, wherein the alloy material comprises the following components in parts by weight: 20-63 parts of polypropylene, 15-58 parts of polyamide, 10-30 parts of glass fiber, 10-30 parts of a halogen-free flame retardant, 1-10 parts of a compatilizer, 1-5 parts of a micro-crosslinking agent, 0.2-3 parts of a modified inorganic nano filler, 0.1-1 part of a coupling agent, 0.1-1 part of a flow modifier and 0.2-2 parts of other additives. The alloy material has the advantages of high strength, high modulus and the like. However, the heat resistance, hydrolysis resistance and glycol resistance of the alloy material are not sufficient.
