Abstract

The invention discloses a reinforced nylon material without floating fiber, which is prepared from the following raw materials in percentage by weight: 42% of polyamide 6, 15% of polyamide 66, 34% of glass fiber, 1% of compatibilizer, 2% of film painting agent, 3% of toughening agent, 0.3% of antioxidant, 0.4% of nucleating agent, 0.3% of coupling agent and 2% of floating fiber resisting agent. The invention also discloses a preparation method of nylon material, which comprises the steps of drying the polyamide 6 and the polyamide 66, throwing the raw materials into a high-speed mixer for high-speed mixing, then throwing the mixed the raw materials into a double-screw extruder, and finally granulating and packaging to obtain the product via melting, mixing, extruding, cooling and drying sequentially. The high-performance reinforced nylon material without floating fiber has the characteristics of high rigidity, high toughness, high liquidity, high heat resistance, no floating fiber and the like.

Description

technical field [0001] The invention relates to a non-floating fiber reinforced nylon material and a manufacturing method thereof. Background technique [0002] Because nylon has many characteristics, it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, papermaking machinery, communication supplies, etc. [0003] With the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the lightweight of mechanical equipment, the demand for nylon will be higher and greater. In particular, as a structural material, nylon has high requirements for its strength, heat resistance, and cold resistance. However, the mechanical strength and heat resistance of nylon itself are not very high, and it is difficult to meet the requirements for use as a structural part. Therefore, it is necessary to modify nylon to improve its performance and expand its application field. [000...
