Abstract

The invention discloses a nylon composite, a preparation method, application thereof and a plastic product of the nylon composite. The nylon composite mainly comprises the following components: high-temperature nylon, nanometer conductive material, lubricant, surfactant and antioxidant, the parts by weight of the components are as follows: 70-95 parts of nylon, 3-25 parts of nanometer conductive material, 0.1-3 parts of lubricant, 0.1-1.8 parts of surfactant, 0.3-3.5 parts of antioxidant and 0.5-2.8 parts of compatilizer, wherein the content of the high-temperature nylons can be replaced by 0-8 parts by mass of common nylon; the surface resistivity of the nylon composite is 1.5-900*10<7> omega.mm under the condition of ASTMD257. In comparison with the prior art, the nylon composite is added with the nanometer conductive material, the surface resistivity is reduced, and the nylon composite has an antistatic effect.

Description

[0001] technical field [0002] The invention relates to a composite material, in particular to an antistatic nylon composite material, a preparation method of the composite material, an application of the composite material, and a plastic product using the nylon composite material. [0003] Background technique [0004] Polyamide fiber is commonly known as nylon (Nylon), and its English name is Polyamide (abbreviated as PA). It is a general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main molecular chain. Existing nylons include polydecanediamine sebacate (nylon 1010), polyundecamide (nylon 11), polydodecamide (nylon 12), polycaprolactam (nylon 6), polyhexamethylene sebacamide (nylon 610), polyhexamethylene dodecyl diamide (nylon 612), polyhexamethylene adipamide (nylon 66), polyoctylamide (nylon 8), poly 9-aminononanoic acid (nylon 9), polypara P-phenylene phthalamide (PPTA), poly-m-phenylene isophthalamide (MPIA), polypara-benzamide (PBA...
