Embodiment example 1

[0031] Add 193g of polyvinylidene fluoride, 3g of other additives, 4g of 1-butyl-3-methylimidazolium hexafluorophosphate into the Haake rheometer at 190°C for 15min at a speed of 50 rpm, and then pass through the twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C. The prepared composition was hot-pressed at 190°C, and its antistatic properties, mechanical properties and light transmittance were measured and analyzed by DSC, TEM and FTIR. The results of the analysis are shown in the accompanying drawings.

Embodiment example 2

[0033] Put 189g of polyvinylidene fluoride, 3g of other additives, and 8g of 1-butyl-3-methylimidazolium hexafluorophosphate into a Haake rheometer at 190°C for 15 minutes at a speed of 50 rpm, and then pass through a twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C. The prepared composition was hot-pressed at 190°C, and its antistatic properties, mechanical properties and light transmittance were measured and analyzed by DSC, TEM and FTIR. The results of the analysis are shown in the accompanying drawings.

Embodiment example 3

[0035] Put 177g of polyvinylidene fluoride, 3g of other additives, 20g of 1-butyl-3-methylimidazolium hexafluorophosphate into the Haake rheometer at 190°C for 15min, at a speed of 50 rpm, and then pass through the twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C.

Abstract

The present invention relates to a permanent antistatic polyvinylidene fluoride (PVDF) composition and a preparation method thereof. The composition comprises the following components, by weight, 68-99.4% of polyvinylidene fluoride, 0.5-30% of an ionic liquid antistatic agent, and 0.1-2% of other additives. During preparation, polycarbonate, a fluorine-substituted polyolefin additive and an ionic liquid are added to a banbury mixer to carry out melting blending at a temperature of 170-200 DEG C until mixing is uniform, the mixed material processed from the process is subjected to melting extrusion through a twin-screw extruder, and then granulation and drying are performed, wherein extrusion temperatures of various regions of the twin-screw extruder are maintained at a temperature of 160-190 DEG C. The composition has the following advantages that: 1, the product has good transparency and excellent antistatic property, and the antistatic property of the material is less affected by air humidity, and the resulting antistatic property is permanent, 2, the process is simple, processing is convenient, the use amounts of the ionic liquid antistatic agent and other additives are less, and the obtained PVDF composition has excellent mechanical properties, and 3, environmental protection requirements are met, the raw materials have characteristics of no toxicity and no harm, and no toxic element exists with chemical analysis.

Description

technical field [0001] The present invention relates to a permanent antistatic polyvinylidene fluoride composition and a preparation method, in particular to a permanent antistatic transparent polyvinylidene fluoride composition with good transparency, excellent antistatic performance, environmental protection requirements and no toxic elements. its preparation method. Background technique [0002] PVDF is a crystalline polymer with a glass transition temperature of -39°C, a crystallization melting point of about 170°C, and a thermal decomposition temperature above 316°C. It has excellent mechanical properties, good impact resistance, wear resistance and chemical stability. At room temperature, PVDF is not corroded by acids, alkalis, strong oxidants and halogens, and is very stable to organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, alcohols and aldehydes, and is in hydrochloric acid, nitric acid, sulfuric acid and dilute and concentrated (40%) lye.
