Problems solved by technology

However, the development of colored flame candles is slow. From the initial paraffin-type colored flame candles to today's non-paraffin-type colored flame candles, most of them are made by directly adding coloring agents to ordinary candles. Colored flame candle, the candle body is divided into two layers, the outer layer is covered with thermoplastic material polypropylene, the inner layer is made of paraformaldehyde as the main combustion agent, the content is 76%-80%, and it is prepared by adding adhesives, solvents, etc. Paraformaldehyde is extremely harmful to the human body and the environment; Chinese patent application CN200710011373.9 discloses a kind of colored flame candle, its main combustion agent is paraffin, add stearic acid, beeswax, hair coloring substances, etc., paraffin is a long carbon chain alkane , the yellow-orange flame in the combustion process has a greater effect on covering other colored flames; Chinese patent application CN200710039906.4 uses urethane as the main combustion agent, which has strong hygroscopicity and is difficult to form
Begin to turn to adopt trimethyl citrate to make main combustion agent in recent years, as the colored flame candle of Chinese patent application CN91111832. Trimethyl citrate is used as the main combustion agent of the candle body, but there are defects of improper handling of the wick, which leads to serious yellow core when the candle burns, and the phenomenon of "dry branches"
As a result, the market for colored flame candles is still not optimistic, and there is no large-scale production of candles.

Embodiment 1

[0034] Example 1 Preparation method of green flame candle

[0035] 1. Put an appropriate amount of cotton thread in a 6% sodium hydroxide solution, heat to reflux for 2 hours, take it out and rinse with deionized water repeatedly, dry it, add the cotton thread to a mixed solution of 2% hydrochloric acid concentration and 3% ammonium chloride concentration In the middle, heat to reflux for 2 hours, take out and rinse repeatedly with deionized water, and dry.

[0036] 2. Take part of the above treated cotton thread and soak it in 0.5% nitric acid solution for half an hour.

[0037] 3. Take part of the cotton thread treated in step 1 and put it in 4% boric acid solution, soak for 1 hour, take it out, fully dry it, soak it in 3% ammonium nitrate solution for half an hour, take it out and dry it to form the color core.

[0038] 4. Wind a hair color wick and a burning wick into a candle wick.

[0039] 5. Weigh 6.500g of trimethyl citrate, 0.750g of stearic acid amide, and 0.150g of stearyl a...

Embodiment 2

[0041] Example 2 Preparation method of blue flame candle

[0042] Steps 1 and 2 are the same as the above example.

[0043] Part of the candle wicks processed in step 1 are soaked in a 15% copper chloride solution for one hour and taken out. After drying, they are soaked in a 3% ammonium nitrate solution for half an hour, and then taken out and dried to form a color wick.

[0044] Wrap a hair color wick and a burning wick to form a candle wick.

[0045] Weigh 7.200g of trimethyl citrate, 0.950g of stearic acid amide, and 0.190g of stearyl alcohol, put it in a container and heat it to melt, add 1.100g of anhydrous copper chloride to uniformly disperse the copper chloride in the molten liquid. Put the candle wick in the mold, pour the molten candle liquid, and cool it to form a blue flame candle.

[0046] The detection method is the same as in Example 1. figure 2 The blue flame of the candle in Example 2 is relatively pure, with less variegated color, and the commercially available blue...

Embodiment 3

[0047] Example 3 Preparation method of red flame candle

[0048] Steps 1 and 2 are the same as the above example.

[0049] Part of the candle wicks processed in step 1 are soaked in a 20% lithium chloride solution for one hour and taken out, dried and then soaked in a 3% ammonium nitrate solution for half an hour, and taken out and dried to form a color wick.

[0050] Wrap a hair color wick and a burning wick to form a candle wick.

[0051] Weigh 7.300g of trimethyl citrate, 0.790g of stearic acid amide, 0.200g of stearyl alcohol, and 1.100g of anhydrous lithium acetate, put it in a container and heat it to melt, put the candle wick in a mold, and pour it into the molten candle liquid , Cooling into a red flame candle.

[0052] The detection method is the same as in Example 1. image 3 The light intensity of the red flame candle in Example 3 is much higher than the light intensity of the commercially available red flame candle, and compared with the commercially available candle, the w...

Abstract

The invention discloses a method for making a color flame candle. A main burning agent of the color flame candle is made from trimethyl citrate, has the melting point of about 76 DEG C, does not produce substances which are harmful to the environment, and is an ideal raw material for making a color flame candle. The candle body of a color flame candle comprises a main burning agent, a combustion improver, a demolding agent and a color developing agent; a candle core comprises a color developing core and a burning core; the burning core is subjected to degreasing, calcium removing, sodium removing and nitration treatment; the color developing core adsorbs the color developing agent and an oxidation promoting agent after being subjected to degreasing, calcium removing and sodium removing treatment; and the burning core and the color developing core are screwed together for constructing the candle core, and the candle core is put into a uniformly-molten candle body liquid for cooling and molding. The color flame candle made by using the method has larger flame and purer color, is prevented from dripping and becoming dry, and is prevented from being bent and deformed under high-temperature conditions.

Description

Technical field [0001] The invention relates to the field of preparation of colored flame candles, and more specifically to the preparation of a color flame candle with pure color and environment-friendly. Background technique [0002] The invention and development of colored flame candles is a milestone in the development history of the world candle industry. In the early 20th century, foreign countries began to study colored flame candles, and in the 1980s, domestic research also began. However, the development of color flame candles has been slow. From the original paraffin type color flame candles to today's non-paraffin type color flame candles, most of them are directly made by adding hair color agents to ordinary candles. For example, the previous US patent application 5,179,922 discloses one Color flame candle, the candle body is divided into two layers, the outer layer is covered with thermoplastic material polypropylene, the inner layer is made of paraformaldehyde, the ...
