Embodiment 1

[0041] Preparation method of ABS / PVDF composite material with wide temperature range, as follows:

[0042] Step 1, weigh 5g of the matrix polymer added to 0.1L of DMF (dimethylformamide) solvent stirred until the matrix polymer is completely dissolved to give the polymer group. The matrix polymer is composed of polyvinylidene fluoride (PVDF), polyvinylidene polyvinylidene copolymer (P (VDF-CTFE)), polyvinylidene fluoride-hexafluoropropylene copolymer (P (VDF-HFP)).

[0043]Step 2: Weigh 3g abs resin (acrylonitrile-butadiene-styrene) and add it to 0.1L DMF (dimethylformamide) solvent, stir well for 3-6 hours, until the ABS resin is completely dissolved to give ABS solution. In ABS resins, the mass fraction of acrylonitrile is 20%, the mass fraction of butadiene is 30%, and the mass fraction of styrene is 50%.

[0044] Styrene acrylonitrile (SAN) where the styrene content is 20-40%, acrylonitrile content is 60-80%, polycarbonate + acrylonitrile butadiene styrene (PC + ABS), where th...

Abstract

The invention discloses a preparation method of ABS / PVDF composite material with wide temperature range. In the prior art, there is a defect that the performance of dielectric materials attenuates seriously in high-temperature environments. The present invention is as follows: 1. Add the base polymer into the polar solvent to obtain the polymer base. 2. Add ABS resin to polar solvent to obtain ABS solution. 3. Add the ABS solution into the polymer base, stir and sonicate to obtain the ABS / PVDF blend. 4. Coating the ABS / PVDF blend solution on the quartz plate to obtain the prototype of the composite film. The prototype of the composite film is dried and then heat treated and quenched. The present invention uses ABS resin as an additive to make a composite material. Compared with the existing dielectric material, the prepared composite material still has superior performance in a high temperature environment of 70°C, which makes the ABS / PVDF prepared by the present invention Composite film materials have stronger environmental adaptability.

Description

Technical field [0001] The present invention belongs to the field of dielectric material preparation technology, specifically relates to a high energy storage, high discharge efficiency, and can be used stably at high temperatures ABS / PVDF composite preparation method. Background [0002] With the development of the technical level, the replacement cycle of electronics, home appliances, communications and other industries is getting shorter and shorter, and film capacitors have become indispensable electronic components to promote the upgrading of the above industries with their good electrical properties and high reliability. In the next few years, with the further development of digitalization, informatization and network construction and the increase of investment in power grid construction, electrified railway construction, energy-saving lighting, hybrid vehicles and the upgrading of consumer electronic products, the market demand for film capacitors will further show a rap...
