Flame-retardant sealing filler for electronic component and preparation method of flame-retardant sealing filler

Abstract

The invention discloses a flame-retardant sealing filler for an electronic component and a preparation method thereof, and the flame-retardant sealing filler for the electronic component comprises the following components in parts by weight: 60 parts of modified resin, 2 parts of a flame retardant, 20 parts of a filler and 10 parts of an auxiliary agent, and the preparation method of the flame-retardant sealing filler for the electronic component specifically comprises the following steps: S1, taking a proper amount of modified resin and a proper amount of flame retardant, adding the modified resin and the flame retardant into a reaction kettle, heating and uniformly stirring; s2, performing vacuum dehydration on the mixture prepared in the step S1; s3, adding the mixture prepared in the step S2 and a proper amount of filler into a stirring kettle, and uniformly stirring; and S4, continuing to add an auxiliary agent into the reaction kettle, uniformly stirring, and naturally cooling to room temperature to obtain a finished product. The whole preparation process is simple, the production cost is low, the flame-retardant effect is good, the sealing requirements of various electronic components are met, the flame retardant adopts the metal hydroxide, and the production is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sealing packing, in particular to a flame-retardant sealing packing for electronic components and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the electronic and electrical industry, the performance requirements of its materials have become more and more stringent, especially the environmental protection and flame retardancy of materials. Due to the development of electronic components towards high integration, ultra-miniaturization, and ultra-thinness, the connection technology between materials must be replaced by new adhesive technology. At present, many outdoor power equipment, especially power control and monitoring equipment, need to have functions such as heat preservation, water insulation, and dust prevention, so sealing packing is required to ensure airtightness. However, most of the sealing packings currently on the market have the ...
