Abstract

Disclosed is a black aluminum alloy. The manufacturing process of the black aluminum alloy comprises the steps that (1) the aluminum alloy is made into fine powder, and the fineness degree of the fine powder is 150 meshes to 180 meshes; (2) the aluminum alloy fine powder obtained in the first step is added into foaming agents and then is stirred and mixed for 20 minutes at the high speed; (3) black pigment is added in a mixture obtained in the second step and then is stirred and mixed for 40 minutes at the high speed; (4) a mixture obtained in the third step is heated to 680 DEG C to 7000 DEG C, the molten mixture is stirred at the high speed until the mixture generates bubbles, and stirring continues; (5) stirring lasts for 30 minutes, the temperature in the fourth step is kept, heating is stopped until the bubbles are not generated, cooling is carried out, and the black aluminum alloy is obtained. The manufacturing process has the beneficial effects that the inside color and the outside color of metal are consistent, a manufactured product will never fade, paint is not required, the manufacturing cost is low, no pollution exists in the production process, and the black aluminum alloy is a good environment-friendly product.

Description

A kind of black aluminium alloy

Technical field

The present invention relates to a kind of chromatic metallic, especially a kind of black aluminium alloy.

Background technology

Along with the development of society, the standard of living of people promotes day by day, the requirement of people to life is also more and more higher, automobile, motorcycle, bike have various color, tradition colouring has been come by paint, paint intelligence changes the color of coating for metal surfaces, metal color inherently can not be changed, and production and the use procedure of paint all can have a huge impact environment, cause the phenomenon that people's living environment worsens, be therefore badly in need of a kind of new technology and solve above-mentioned technological deficiency.

Summary of the invention

The invention provides a kind of black aluminium alloy.

The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:

A kind of black aluminium alloy, its manufacturing process steps is:

(1) aluminium alloy is made fine powder, fineness is 150-180 order;

(2) the aluminium alloy fine powder of gained adds whipping agent in step 1, and high-speed stirring mixes 20 minutes;

(3) in the mixture of step 2 gained, add black pigment, high-speed stirring mixes 40 minutes;

(4) 680-700 degree Celsius is put in the heating of the mixture of step 3 gained, high-speed stirring is carried out to the mixture of fusing, has bubble to produce to mixture, continue to stir;

(5) Keep agitation 30 minutes, and keep temperature described in step 4, bubble to be no longer included produces, and stops heating, and cools, obtain black aluminium alloy.

Described black pigment is copper-chrome black.

Described black pigment consumption is the 5%-7% of aluminium alloy weight.

The invention has the beneficial effects as follows: solid colour inside and outside metal, made product is will never fade, and without the need to paint, cost of manufacture is little, and production process is pollution-free, is a kind of good environmentfriendly products.

Embodiment

A kind of black aluminium alloy, its manufacturing process steps is: aluminium alloy is made fine powder by (1), and fineness is 150-180 order; (2) the aluminium alloy fine powder of gained adds whipping agent in step 1, and high-speed stirring mixes 20 minutes; (3) in the mixture of step 2 gained, add black pigment, high-speed stirring mixes 40 minutes; (4) 680-700 degree Celsius is put in the heating of the mixture of step 3 gained, high-speed stirring is carried out to the mixture of fusing, has bubble to produce to mixture, continue to stir; (5) Keep agitation 30 minutes, and keep temperature described in step 4, bubble to be no longer included produces, and stops heating, and cools, obtain black aluminium alloy; Described black pigment is copper-chrome black.Described black pigment consumption is the 5%-7% of aluminium alloy weight, solid colour inside and outside metal, and made product is will never fade, and without the need to paint, cost of manufacture is little, and production process is pollution-free, is a kind of good environmentfriendly products.
