Problems solved by technology

Nylon 6 itself has excellent comprehensive properties such as wear resistance, oil resistance, self-lubrication, insulation, excellent mechanical properties, easy molding and processing, and resistance to weak acids and weak bases. Therefore, it is widely used in the automotive field, daily necessities, and water meter and pump industries. In the industrial application of water meters and pumps, nylon 6 usually needs to have excellent strength and durability, excellent coloring performance, perfect surface appearance, good processability and high thermal stability, but ordinary nylon 6 has a dry state And the defect of low impact strength at low temperature, at the same time, the high water absorption rate seriously affects the dimensional stability of nylon 6 products. In recent y

Abstract

The invention discloses a special glass fiber reinforced nylon 6 material for water gauges and water pumps, and a preparation method of the nylon 6 material. The material comprises the following components in parts by weight: 42.4-53 parts of nylon 6, 40 parts of glass fiber, 5-15 parts of flexibilizer, 0.8 parts of compatilizer, 0.3 parts of antioxygen, 1.0 part of coupling agent, and 0.3-0.5 parts of lubricant, wherein the flexibilizer is an ethylene-vinyl acetate (EVA) copolymer, and the lubricant is an ethylene bistearic amide graft (TAF). According to the nylon 6 material and the preparation method, the special flexibilizer-EVA is adopted; the problem that the nylon material is poor in toughness is solved, and the water resistance of a composite is improved effectively at the same time; the industrial production cost is lowered; the high-performance lubricant TFA is found, exerts a lubrication effect and has a function of preventing leakage of the glass fiber at the same time; the comprehensive performance of the nylon 6 material is good; the appearance is good; and no floating fiber exists on the surface.

Description

technical field [0001] The invention relates to a nylon 6 material, in particular to a special glass fiber reinforced nylon 6 material for water meters and pumps and a preparation method thereof. Background technique [0002] Nylon 6 (also known as polyamide 6, PA6,) is the earliest variety developed in engineering plastics, and it is also one of the varieties with the largest output among polyamides. Nylon 6 itself has excellent comprehensive properties such as wear resistance, oil resistance, self-lubrication, insulation, excellent mechanical properties, easy molding and processing, and resistance to weak acids and weak bases. Therefore, it is widely used in the automotive field, daily necessities, and water meter and pump industries. In the industrial application of water meters and pumps, nylon 6 usually needs to have excellent strength and durability, excellent coloring performance, perfect surface appearance, good processability and high thermal stability, but ordinary...
