Problems solved by technology

[0002] Silver products will turn black after a long time. There are many reasons for the blackening: for example, when exposed to chemicals such as acids and alkalis, you need to spray perfume and hairdressing products before wearing silver jewelry. Take off the jewelry when bathing and avoid contact with bathing Dew soap and other supplies, please take off the jewelry when you sleep, avoid wearing it overnight, hair entangled on the jewelry, human body sweat will corrode the silver jewelry, silver products are impure, of course, even if they are not loaded at the same time, the silver jewelry will still remain after a long time It will be oxidized and discolored and needs to be polished, but the existing polishing agent is harmful to silver, and the polishing effect is not good

Embodiment 1

[0019] A polishing agent for silver products, which consists of the following components according to mass percentage:

[0020] A methylparaben 0.5%, the concentration is 5% hydroxyethyl cellulose 25%,

[0021] B sodium carbonate 12%, demineralized water 54%, bentonite 4%,

[0022] C lauryl polyoxyethylene ether 4%,

[0023] D3-octadecyl mercaptopropionate 2%, white grape juice 5%.

[0024] The processing method of above-mentioned silver product polishing agent, comprises the following steps:

[0025] (1) Put A in a mixer and stir to heat to 90°C,

[0026] (2) Add to the reaction kettle, add component B, close the autoclave and stir at 120°C for 1 hour;

[0027] (3) Add component C and stir for 10 minutes at room temperature and pressure;

[0028] (4) Add component D, rotary distillation for 2 hours to obtain polishing agent.

[0029] The resulting polish was slightly yellow in color.

Embodiment 2

[0031] A polishing agent for silver products, which consists of the following components according to mass percentage:

[0032] A methylparaben 0.2%, the concentration is 5% hydroxyethyl cellulose 26%,

[0033] B sodium carbonate 17%, demineralized water 58%, bentonite 6%,

[0034] C lauryl polyoxyethylene ether 3%,

[0035] D3-octadecyl mercaptopropionate 2%, red grape juice 4%.

[0036] A processing method of a polishing agent for silver products, comprising the following steps:

[0037] (1) Put A in a mixer and stir to heat to 80°C,

[0038] (2) Add to the reaction kettle, add component B, close the autoclave and stir at 110-130°C for 0.5 hours;

[0039] (3) Add component C and stir for 15 minutes at room temperature and pressure;

[0040] (4) Add component D, and rotatively distill for 1.5 hours to obtain a polishing agent.

[0041] The resulting polishing agent was rose red.

Abstract

The invention discloses a silverware polishing agent. The silverware polishing agent is composed of, by mass, A, 0.1-0.5% of methyl parahydroxybenzoats and 20-30% of hydroxyethyl cellulose with the concentration being 5%; B, 10-20% of sodium carbonate, 50-60% of softened water and 3-6% of bentonite; C, 2-5% of lauryl alcohol polyoxyethylene; and D, 1-5% of 3-mercaptopropionic acid octadecyl and 2-6% of grape juice. According to the silverware polishing agent obtained through a scientific processing method, due to the fact that the 3-mercaptopropionic acid octadecyl and the grape juice of certain proportions are used as corrosion inhibitors, the polishing effect is good, silverware is not damaged, and the silverware can be made to be bright as new.
