Problems solved by technology

At present, the commonly used flame-retardant nylon materials not only have low toughness, but also the flame-retardant raw materials used are usually halogen-containing, which will produce harmful gases that are not conducive to the human body and the environment during the flame-retardant process. Therefore, research on halogen-free flame-retardant nylon composite materials, especially Halogen-free flame-retardant composite materials reinforced with basalt fibers have great practical significance and necessity

Abstract

The invention discloses a continuous basalt fiber-reinforced halogen-free flame-retardant nylon material and a preparation method thereof. The continuous basalt fiber-reinforced halogen-free flame-retardant nylon material is prepared by mainly mixing continuous basalt fiber-reinforced nylon master batches and halogen-free flame-retardant master batches, wherein each continuous basalt fiber-reinforced nylon master batch mainly comprises a continuous basalt fiber, nylon resin and a silane coupling agent; and each halogen-free flame-retardant master batch mainly comprises polyolefin resin, a halogen-free fire retardant and a flame-retardant synergist. The product obtained by mixing the continuous basalt fiber-reinforced nylon master batches and the halogen-free flame-retardant master batches in proportion has the advantages of good fire-retardant property, excellent mechanical property, simple preparation process, low cost, environmental friendliness and wide market application prospect and meets the requirements for industrialized production, green and environmental friendliness.

Description

technical field [0001] The invention relates to a fiber-reinforced polymer material and a preparation method thereof, in particular to a continuous basalt fiber-reinforced halogen-free flame-retardant nylon material and a preparation method thereof, belonging to the technical field of modified nylon composite materials. Background technique [0002] As a kind of volcanic rock, basalt is evolved in the depths of the earth through high temperature and high pressure and a long history. Basalt has been made into tiles and slabs through casting technology and has been used in the construction market for many years. The cast basalt steel pipe lining has high wear resistance and is widely used in industrial production. In addition, basalt can also be used as concrete in a crushed state. of aggregates. [0003] Continuous fibers extruded from natural refractory basalt can be used to replace asbestos fibers in almost all applications. In the past ten years, basalt fiber has become ...
