Embodiment 1

[0034] (1) Weigh 15 kg of zinc oxide, 45 kg of aluminum powder and 15 kg of boron nitride, stir and mix evenly to prepare a mixed thermally conductive filler.

[0035] The zinc oxide, aluminum powder and boron nitride are in powder or granular form, and their shape can be amorphous, spherical or any shape, preferably with an average particle diameter of 0.1-100 microns.

[0036] (2) Use a coupling agent to modify the surface of the thermally conductive filler: Take 65 kg of the above-mentioned mixed thermally conductive filler and stir it at a high speed at a speed of 2000r / min, and spray 0.65 kg of the coupling agent tris(dioctylpyrophosphoryl oxide base) isopropyl titanate, and then continue to stir for 10 minutes to obtain a modified thermally conductive filler;

[0037] (2) Mix 35 kg of methyl vinyl silicone rubber, all the above-mentioned modified thermally conductive fillers and 4 kg of tetramethylthiuram disulfide in a mixer for 2 hours to prepare thermally conductive s...

Abstract

The invention discloses a glass fibre heat-conductive silicon sheet for a notebook computer and a preparation method thereof; the glass fibre heat-conductive silicon sheet for the notebook computer comprises glass fibre cloth; heat-conductive silicon is coated on the two surfaces of the glass fibre cloth; the heat-conductive silicon is formed by compounding the following components in parts by weight: 35 parts of methyl vinyl silicone rubber, 60-70 parts of heat-conductive filler, 2-6 parts of tetramethyl thiuram disulfide, and a coupling agent; the use amount of the coupling agent is 0.5-2% of that of the heat-conductive filler; and the heat-conductive filler is the mixture of zinc oxide, aluminium powder and boron nitride. The glass fibre heat-conductive silicon sheet for the notebook computer disclosed by the invention is effectively contacted with a heat emitting component and a heat dissipating component; the contact thermal resistance between the heat emitting component and the heat dissipating component is reduced, and therefore, the glass fibre heat-conductive silicon sheet for the notebook computer has higher heat-conductive coefficient.

Description

technical field [0001] The invention relates to a silica gel sheet and a preparation method thereof, in particular to a thermally conductive silica gel sheet with glass fiber for a notebook computer and a preparation method thereof. Background technique [0002] Notebook computer, the English name is NoteBook, commonly known as notebook computer. Portable, laptop, notebook computer, referred to as NB, also known as laptop computer or laptop computer (Hong Kong and Taiwan called it notebook computer 1), is a small, portable personal computer, usually weighing 1-3 kg. Its development trend is that the volume is getting smaller and smaller, the weight is getting lighter and lighter, and the function is more and more powerful. Like a Netbook, also known as a netbook, the main difference from a PC is that it is portable and easy to carry. [0003] Compared with desktop computers, notebook computers have similar structural components (display, keyboard / mouse, CPU, memory, and ha...
