Embodiment approach

[0057] As an embodiment of the present invention, the particle size of the barium titanate is 0.02 μm-0.8 μm; more preferably 0.05 μm-0.5 μm.

[0058] (meth)acrylate copolymer

[0059] (Meth)acrylate copolymers are the copolymerization products of acrylate monomers, methacrylate monomers and other vinyl monomers. According to the nature of each monomer, the monomer is divided into: hard monomer, soft monomer and functional monomer. The hard monomer has a high glass transition temperature and imparts hardness, tensile strength, cohesion and wear resistance to the coating film; the soft monomer imparts certain flexibility, extensibility and durability to the coating film. The introduction of functional monomers is to introduce functional groups to endow the polymer with a certain cross-linking reactivity and play a role in cross-linking.

[0060] In the present invention, the monomers for preparing the (meth)acrylate copolymer include at least alkyl acrylate, alkyl methacryl...

Embodiment approach 1

[0167] Embodiment 1: The present invention provides a dielectric material composition, comprising:

[0168] Barium titanate 10-13 parts;

[0169] 20-26 parts of (meth)acrylate copolymer;

[0170] 8-10 parts of polyurethane;

[0171] 100-130 parts of water.

Embodiment approach 2

[0172] Embodiment 2: The (meth)acrylate copolymer described in Embodiment 1 is an alkyl (meth)acrylate, a (meth)acrylate containing a functional group, and 9-vinyl anthracene in a weight ratio of (10- 20): (3-8): (0.1-1) prepared.

Abstract

The invention provides a dielectric material composition, which is prepared from the following raw materials in parts by weight: 10-13 parts of barium titanate, 20-26 parts of (methyl)acrylate copolymer, 8-10 parts of polyurethane and 100-130 parts of water. The dielectric material composition has a very high dielectric constant and a relatively low dielectric loss.

Description

technical field [0001] The invention relates to a dielectric material composition, in particular to the field of H05B. Background technique [0002] Commonly used in the manufacture of electroluminescence mainly includes substrates, primer film layers, bottom plate film layers, dielectric film layers, phosphor film layers, conductive transparent electrode layers and transparent coating layers for encapsulation. [0003] Dielectric material refers to dielectric, which is an electrical insulating material. Dielectric properties refer to the properties of dielectric materials that are polarized under the action of an electric field due to the rearrangement of charges. Common dielectric materials include inorganic dielectric materials and organic dielectric materials. Organic dielectric materials have good flexibility, but are generally inferior to inorganic dielectric materials in terms of high temperature resistance, radiation resistance, mold resistance, arc resistance and ...
