example 1

[0154] Example 1: a preparation method of octadecyltrimethylammonium bromide antibacterial paraffin wax (No. 50)

[0155] In this example, No. 50 solid paraffin was used as the raw material, octadecyltrimethylammonium bromide (OTAB) was used as the antibacterial agent, stearic acid was used as the OTAB dispersion modifier, and a two-step mixing method of low temperature and high temperature was adopted. OTAB is evenly dispersed in paraffin wax to prepare a kind of OTAB antibacterial paraffin wax (No. 50) with excellent antibacterial properties. The preparation process is carried out in the following 8 steps:

[0156] (1) Paraffin wax melting: Weigh a certain amount of solid paraffin and place it in a beaker. Use a universal electric furnace to slowly heat the solid paraffin until it melts, and finally effectively control and stabilize the melt temperature at 80-90°C. ;

[0157] (2) Weighing of stearic acid: according to the ratio of OTAB:stearic acid=1:5~10, w...

Abstract

The invention relates to a preparation method of octodecyl trimethyl ammonium bromide (OTAB) antibacterial solid paraffin, which takes solid paraffin as raw material, OTAB as antibacterial agent, and stearic acid as dispersing modifier. The preparation method comprises the steps of: 1. slowing heating the solid paraffin until the solid paraffin is melted at the constant temperature of 80-90 DEG C; 2. weighing and taking the stearic acid according to the proportion of 1: 5-10 between the OTAB and the stearic acid; 3. slowing heating the stearic acid until the stearic acid is melted at the constant temperature of 80-90 DEG C; 4. weighing and taking the OTAB according to the dosage of the OTAB accounting for 0.6% of the weight of the solid paraffin; 5. adding the OTAB into the obtained stearic acid melt with the temperature of 80-90 DEG C, and evenly stirring; 6. adding the mixed melt of the OTAB and the stearic acid into the paraffin melt with the temperature of 80-90 DEG C, and evenly stirring; 7. heating the turbid mixed melt of the OTAB, the stearic acid and the paraffin to 100-110 DEG C, and slowing stirring until the turbid mixed melt is clear and transparent; and 8. naturally cooling the obtained mixed melt to be room temperature, and obtaining the OTAB antibacterial solid paraffin. The OTAB antibacterial solid paraffin is excellent in antibacterial performance, good in safety, simple in technique, low in cost, easy to popularize and apply, wide in usage and remarkable in social and economic benefits.

Description

[0001] 1. Technical field [0002] The invention relates to a preparation method of octadecyltrimethylammonium bromide (OTAB) antibacterial solid paraffin, in particular to a dispersing modification which uses solid paraffin as raw material, OTAB as antibacterial agent, and stearic acid as OTAB. The antibacterial agent adopts a low-temperature and high-temperature two-step mixing and melting method to disperse OTAB evenly in paraffin wax, which is suitable for the preparation of an OTAB antibacterial paraffin wax with excellent antibacterial properties. [0003] 2. Background technology [0004] Microorganisms are a class of organisms that are widely distributed in nature, and are small in size, various in variety, large in number, fast in metabolism and reproduction, easy to mutate and strong in adaptability. Some microorganisms can cause diseases of humans, animals and plants. Malaria, an infectious disease that occurred in history, killed 80 million people a year [1] ...
