Embodiment Construction

[0017] The present invention is a drilling lubricating aluminum composite material, comprising a resin composition and an aluminum foil, characterized in that: the resin composition is polyethylene glycol (PEG), polyvinyl alcohol (PVA), polyethylene glycol sorbitol Polyoxyethylene sorbitan fatty acid ester, cocount alcohol polyethylene glycol ether, nonyl phenol polyethylene glycol ether, polypropylene glycol glycol ether ( polyoxypropylene, polyoxyethylene ether) at least three optional mixtures, and can also be prepared by adding inorganic fillers, solvents, etc.

[0018] Wherein the inorganic filler is silicon dioxide (SiO 2 ), aluminum hydroxide (Al(OH) 3 ), alumina (Al 2 o 3 ), titanium dioxide (TiO 2 ), calcium carbonate (CaCO 3 ) one of them; and the solvent can be water (H 2 O), Methanol (CH 3 OH), ethanol (C 2 h 5 OH), acetone (C 3 h 7 O) One of them.

[0019] In this way, as shown in Figure 1, when one of the above mixed resins is combined on the aluminum...

Abstract

The composite aluminum material includes one layer of resin composition and one layer of aluminum foil. The resin composition is mixture of at least three of PEG, PVA, polyglycol glucitol laurate, polyglycol laurinol ether, polyglycol nonyl phenol ether, polypropanediol glycol ether, etc. and may have inorganic stuffing, solvent, starch, glycerin, etc. The resin composition is combined to aluminum foil through drum painting, rotating painting, showering, electrostatic spraying or screen printing, so as to form the composite aluminum material. The composite aluminum material is for use through spreading on circuit board.

Description

[0001] technical field [0002] The invention relates to a drilling-lubricating aluminum composite material, especially a drilling-lubricating aluminum composite material that can effectively reduce the rate of broken needles when drilling a circuit board. It can simplify the types of resins used and improve production efficiency. For the purpose of mass production, it is suitable for users of circuit board drilling equipment. Background technique [0003] In recent years, with the rapid development of electronic technology, many high-tech electronic industries have come out one after another, making electronic products with more humanization and better functions continue to be introduced, and these electronic products are constantly moving towards light, thin, short and small Trend design development. Various electronic products have at least one motherboard, which is composed of many electronic components and circuit boards, and the function of the circuit board is to carry...
