Abstract
The invention discloses gold foil paper. The gold foil paper comprises constituents of, by weight, 100 parts of powdered gold, 10 parts to 15 parts of copper powder, 2 parts to 10 parts of powdered sulfur, 5 parts to 8 parts of dilauryl thiodipropionate and 0.2 part to 1 part of propylgallate. According to the gold foil paper, the problems that oxidization occurs easily and the like after gold is replaced by copper in the prior art are solved, costs of the gold foil paper is effectively reduced, and the thickness after pressing can reach the thickness of pure gold foil paper; besides, during recovery, the connection performance among structures of the gold foil paper is good, so that gold foil can be taken down easily, and gold in the gold foil can be extracted to be recovered.
Description
Technical field
The present invention relates to a kind of gold foil paper, belong to Material Field.
Background technology
Gold foil paper is with gold thin slice hammer out.Gold is owing to having good ductility and plasticity, and one or two (31.25 grams) proof gold can ten thousand/millimeters thick, area be the gold foil paper of 16.2 square metres hammer out.Namely one gram of gold can make the proof gold foil paper into about 0.5 square metre, and thickness is 0.12um.Gold foil paper standard specification is 9.33*9.33cm, and other regular size lattice also have 8*8cm, 10.9*10.9cm, 4.5*1.5cm, 2.75*2.75cm.
Gold stable in properties, permanent nondiscolouring, anti-oxidant, moisture proof, corrosion-resistant, anti-mildew, anti-insect bite, radiation proof, the gold foil paper tool made with gold has been widely used.Ancient legal system gold foil paper is first purified by gold, then beats through thoroughly tempered, becomes the gold leaf of area 2.5 square centimeters, then be clipped in and smoke in the coal paper that is smelt with kerosene, then beat through the craft of 6-8 hour, make gold leaf become paper tinsel, area is equivalent to about 40 times of gold leaf, then is cut into square.
Traditional handicraft makes gold foil paper, be with gold content be the gold bar of 99.99% for primary raw material, wash, beat, cut the special processing of ten multiple working procedures such as paper tinsel through changing, make it present golden yellow color, bright soft, as light as a feather, as thin as cicada's wings, thickness is less than 0.12 micron.
But this gold foil paper is because of the costliness of sill, and can not be widely used, and bad recovery, be difficult to take off goldleaf, cause the irreversible waste of the energy.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides and meet the low not oxidizable and good gold foil paper reclaimed of cost simultaneously.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of gold foil paper, each composition by weight: bronze 100 parts, copper powder 10-15 part, sulphur powder 2-10 part, dilauryl thiodipropionate 5-8 part, n-propyl gallate 0.2-1 part.
Preferably, above-mentioned gold foil paper, each composition by weight: bronze 100 parts, copper powder 15 parts, 7 parts, sulphur powder, dilauryl thiodipropionate 7.6 parts, n-propyl gallate 0.5 part.
The purity of described bronze is more than 99.9%.
The preparation technology of above-mentioned gold foil paper, comprises the steps,
1) first copper powder, sulphur powder, dilauryl thiodipropionate three are mixed, then leave standstill 10-20 hour after adding n-propyl gallate;
2) mix with bronze after said mixture being polished into the particle of 100-500nm and be pressed into goldleaf.
Beneficial effect of the present invention is:
The problem such as oxidizable after gold foil paper provided by the present invention solves and replaces gold with copper in prior art, effectively reduce the cost of gold foil paper, and the thinness after its compacting also can reach the thinness of proof gold foil paper, and when reclaiming, because the interstructural link performance of its gold foil paper is good, take off well, Jin Kejing wherein extracts recovery again.
