Problems solved by technology

Since the dispersion of flame retardants and antibacterial agents in the substrate is not good, adding two different functional additives respectively will lead to an increase in the amount of additives added. Due to the poor dispersion of additives and substrates, further possible It will have a certain impact on the overall performance of the material
In particular, it should be pointed out that in order to achieve the multifunctionality of polymer materials, it is often necessary to add a large number of multi-component additives to achieve it, and the additives of each component may affect each other, thereby affecting the overall performance of the material.

Abstract

The invention relates to a flame-retardant antibacterial long glass fiber reinforced polypropylene composite material as well as a preparation method and application thereof, belonging to the technical field of high polymer materials. The flame-retardant antibacterial long glass fiber reinforced polypropylene composite material is prepared from the following components in parts by weight: 100 parts of polypropylene, 2 to 10 parts of compatilizer, 20 to 60 parts of glass fiber and 0.05 to 10 parts of guanidine salt flame-retardant antibacterial microspheres. According to the flame-retardant antibacterial long glass fiber reinforced polypropylene composite material, the flame-retardant and antibacterial efficiency of the auxiliary agent is improved, so that the material is excellent in comprehensive mechanical property, has flame-retardant and antibacterial properties, and is suitable for the fields of household appliances, automobile interior and exterior ornaments, fitness equipment, office supplies, daily necessities, toys, sanitary ware and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more particularly, relates to a flame-retardant and antibacterial long glass fiber reinforced polypropylene composite material and its preparation method and application. Background technique [0002] Polypropylene resin is a general-purpose plastic with a wide range of applications. It is one of the varieties with the lowest density among all plastics. It has the advantages of good formability and chemical resistance. It is widely used in various places, such as household appliances, Plastics occupy an important position in the fields of automotive interior and exterior trim, fitness equipment, office supplies, daily necessities, toys, and sanitary ware. However, polypropylene resin has a large shrinkage rate, which makes it difficult to meet the requirements for parts with high size requirements. At the same time, its strength, stiffness, heat resistance and flame retardancy often...
