Abstract

The invention relates to a preparing method of an improved material for encapsulation. The improved material comprises mixed liquid and a powder material, wherein the mixed liquid comprises 15 to 20 parts by weight of resin, 20 to 25 parts by weight of a toughening agent, 1 to 5 parts by weight of a defoaming agent, 15 to 20 parts by weight of a curing agent, 1 to 5 parts by weight of an accelerant and 1 to 5 parts by weight of a closing agent; the powder material comprises 35 to 40 parts by weight of a flame retardant. The method comprises the following steps: 1, preheating a reaction kettle;2, weighing the raw materials; 3, preparing the mixed liquid; 4, pretreating the powder material; 5, preparing the improved material; 6, performing item test on the improved material; 7, performing property test on the improved material; 8, packaging and storing. The improved material has high physical and chemical properties, excellent waterproof and dampproof effects, high hardness, high toughness and excellent stable performance; meanwhile, the method is convenient to operate, high in production efficiency and precise in step.

Description

technical field [0001] The invention relates to the technical field of packaging of electronic components, in particular to a method for manufacturing an improved material for potting. Background technique [0002] With the development of society, insulation materials appear a situation where multiple subjects compete with each other and develop together. Industries related to insulating materials, such as electrical and electronic, transportation, petrochemical, and construction engineering, are developing rapidly. The demand for insulating materials in economic construction has increased sharply, and my country's insulating materials have ushered in a golden stage of development. The main forms of insulating materials are copper clad laminates, potting materials, castables, patch adhesives, etc. [0003] With the development of the industry, higher and higher requirements are placed on the performance of insulating materials. Ordinary requirements can no longer meet the...
