Abstract
The invention provides a permanent antistatic PPS (polyphenylene sulfide)/PA6 (polyamide 6) alloy and a preparation method thereof. The composite material comprises components in percentage by weight as follows: 20-50% of PPS, 10-30% of polycaprolactam, 20-40% of glass fibers, 10-30% of a permanent antistatic agent, 0.3-0.5% of an antioxidant, 0.5-2% of a lubricating agent and 0.2-0.5% of a coupling agent. The alloy has the permanent antistatic effect, is low in production cost, excellent in heat resistance, good in dimensional stability, creep-resistant and resistant to chemical corrosion and is widely applied to electronic appliance casings.
Description
Technical field
The invention belongs to permanent anti-static field of material technology, relate to a kind of permanent anti-static PPS/PA6 Alloy And Preparation Method.This material has permanent anti-static effect, good dimensional stability, ultrahigh rigidity, high rigidity.Be mainly used in electronic apparatus shell etc.
Background technology
Electrostatic is as the general physical phenomenon of one, near during the last ten years along with the develop rapidly of science and technology and the widespread use of macromolecular material, the harm that the reactive force of electrostatic, electric discharge and induction phenomena cause is very serious, and the loss that the harm of annual electrostatic causes in electron trade is great.Problem severity is also the understanding deficiency of a lot of people to static hazard and the ignorant of anti-electrostatic knowledge, often some equipment performances caused because of electrostatic is declined or fault, thinks it is that components and parts premature ageing lost efficacy by mistake.
PPS has excellent heat-resisting, corrosion-resistant, radiation resistance; Itself there is fire-retardant self-extinguishing, just can reach UL94V0 without the need to adding fire retardant.PPS/PA6 alloy is the same with most of macromolecular material has good electrical insulating property, and its surface resistivity is generally 10
12-10
14Ω, easily assemble quiet after in use producing friction, the negative interaction that accumulation of static electricity brings has had a strong impact on production, life, work, sometimes even can cause fire etc.Therefore require that PPS also will have antistatic effect while having good mechanical property, namely surface resistivity reaches 10
6-10
11.
Summary of the invention
The invention provides a kind of permanent anti-static PPS/PA6 Alloy And Preparation Method, by adding permanent anti-static agent in PPS, make PPS material have permanent anti-static effect, the surface resistivity of material can reach 10
6-10
11.
Technical scheme of the present invention is as follows:
The invention provides a kind of permanent anti-static PPS/PA6 Alloy And Preparation Method, this material comprises following component and weight part:
