Method for making color flame candle

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 a colored flame candle, in particular to the preparation of a pure color and environment-friendly colored flame candle. 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 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 ...

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.
