Problems solved by technology

[0002] At present, the market uses vinyl acetate-maleic anhydride (1:1) copolymer as a modifier for candle molding, which is expensive and causes great environmental pollution.
Moreover, when the wick of a colored flame candle is traditionally processed, the wick is not considered to be degreased, resulting in a small amount of color absorbed by the cotton thread and impure color.

Embodiment

[0032] 1. Production of combustion core

[0033] (1) Degreasing the core thread: Put 1 g of cotton thread and 300 ml of 6% NaOH solution into a three-necked flask. One mouth of the three-necked flask was inserted into a condenser, the other mouth was inserted into a thermometer, and the middle mouth was sealed with a rubber stopper. Place the three-necked flask in a temperature-regulating thermostat, heat to boil and reflux for 3.5 hours, and take out the cotton thread. Then put the cotton thread and 300ml deionized water into the cleaned three-necked flask, boil and reflux for 15min, and repeat the operation three times.

[0034] (2) Decalcification and sodium ions of the core wire: Wash the above-mentioned three-necked flask, add absorbent cotton thread, 3% hydrochloric acid and 2% ammonium chloride solution 300ml, reflux and boil for 1.5h, and wash it three times repeatedly with a large amount of deionized water , air dry naturally.

Abstract

The invention discloses a preparation method of a colored flame candle, which comprises the following steps: a. making a candle burning core; b. making a candle color core; c. preparing a candle main burner; d. forming a candle. The present invention adopts polyethylene glycol (molecular weight is 20000) as the molding improver of the candle, which can reduce the expected effect of the candle while reducing the cost of making the candle. The invention uses dilute alkali as the degreasing agent to degrease the candle wick, so that the amount of the color developing agent absorbed by the cotton thread is greatly increased, and the hair color is also purer.

Description

technical field [0001] The present invention relates to a kind of candle, more specifically relates to a kind of preparation method of burning candle with colored flame. Background technique [0002] At present, the market uses vinyl acetate-maleic anhydride (1:1) copolymer as a candle molding improver, which is expensive and causes great environmental pollution. Moreover, when the wick of the colored flame candle is traditionally processed, the wick is not considered to be degreased, which results in less amount of color development absorbed by the cotton thread and impure color development. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a colored flame candle that adopts a new candle shaping improver and a new wick degreasing treatment, which can achieve the same expected effect while reducing the candle production cost, and the degreasing treated candle The amount of hair dye absorbed ...
