Embodiment 1

[0073] By weight, the acid etching solution contains: 30 parts of sulfuric acid with a mass fraction of 50%, 10 parts of titanium chloride with a mass fraction of 40%, 2 parts of sodium lauryl sulfate, 3 parts of organic heterocyclic corrosion inhibitor and water 25 servings.

[0074] First, configure the etching solution according to the above ratio, and place the prepared etching solution in the etching tank for use. At the same time, high-temperature steam is used to clean the surface of the titanium implant to be etched to remove surface oil and obtain a clean titanium implant. Then put the clean titanium implant into the etching solution in the etching tank, and perform ultrasonic treatment for 60 minutes at a temperature of 80° C., then take it out, clean and dry it. Finally, the acid etching solution after acid etching is subjected to aging treatment, and then filtered to obtain titanium dioxide and the acid etching solution for reuse.

Embodiment 2

[0076] In parts by weight, the acid etching solution contains: 45 parts of sulfuric acid with a mass fraction of 60%, 15 parts of sodium chloride with a mass fraction of 50%, 3 parts of sodium lauryl sulfate, 3 parts of nitrite, ethylenediamine tetra 2 parts of acetic acid, 3 parts of alkylsulfonate and 35 parts of water.

[0077] First, configure the etching solution according to the above ratio, and place the prepared etching solution in the etching tank for use. At the same time, high-temperature steam is used to clean the surface of the titanium implant to be etched to remove surface oil and obtain a clean titanium implant. Then put the clean titanium implant into the etching solution in the etching tank, and perform ultrasonic treatment for 80 minutes at a temperature of 100° C., then take it out, clean and dry it. Finally, the acid etching solution after acid etching is subjected to aging treatment, and then filtered to obtain titanium dioxide and the acid etching solut...

Embodiment 3

[0079] In parts by weight, the etching solution contains: 55 parts of sulfuric acid with a mass fraction of 60%, 35 parts of sodium chloride with a mass fraction of 60%, 2 parts of ethylene glycol n-butyl ether, 3 parts of nitrite, ethylenediaminetetraacetic acid 3 parts, 4 parts of alkylsulfonate, 3 parts of aminotetrazole compound, 2 parts of formamide, 3 parts of sulfamic acid, 2 parts of butynediol and 45 parts of water.

[0080] First, configure the etching solution according to the above ratio, and place the prepared etching solution in the etching tank for use. At the same time, high-temperature steam is used to clean the surface of the titanium implant to be etched to remove surface oil and obtain a clean titanium implant. Then put the clean titanium implant into the etching solution in the etching tank, and perform ultrasonic treatment for 90 minutes at a temperature of 110° C., then take it out, clean and dry it. Finally, the acid etching solution after acid etching...

Abstract

The invention discloses an acid etching solution and a titanium implant acid etching treatment method. The acid etching solution comprises, by weight, 30-80 parts of sulfuric acid, 5-40 parts of chlorine salt, 1-5 parts of surfactants, 1-5 parts of corrosion inhibitors and 20-60 parts of water. By means of the technical scheme provided by the invention, the surface quality of a titanium implant obtained after being treated with an acid etching process can be improved.

Description

technical field [0001] The invention relates to the technical field of surface treatment of titanium implants, in particular to an acid etching solution and an acid etching treatment method for titanium implants. Background technique [0002] At present, titanium implants (such as dental implants, intraosseous implants, etc.) are mainly made of pure titanium or titanium alloys, and the surface roughness is improved by sandblasting and acid etching to form a microstructure. In the related art, the surface quality of the titanium implant obtained after the acid etching process is often poor. [0003] The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is the prior art. Contents of the invention [0004] The main purpose of the present invention is to provide an acid etching solution and an acid etching treatment method for titanium implants. The purpose is to improve the su...
