Problems solved by technology

But for wet wipe manufacturers, it is more troublesome to produce lotion in large quantities
The performance is as follows: the first is energy consumption. To prepare the emulsion, it is necessary to heat the water phase to above 80°C, and then heat the oil phase such as various solid waxes to above the melting point, stir until the solid wax is completely dissolved in the oil phase, and slowly heat the water phase. Slowly add to the oil phase and keep stirring for mixing and emulsification, which requires a lot of heat energy; even if the low-energy emulsification method is used, it is very energy-consuming due to the large production volume. After emulsification and cooling, most of the heat energy is lost. Does not comply with current environmentally friendly production methods
The second is time-consuming. During the entire emulsification process, the heating time of the water phase and the oil phase, the mixing emulsification time and the cooling time take a long time, which is not conducive to large-scale production
The third is that special equipment is required. The traditional stirring reactor cannot meet the requirements of emulsification. The preparation of emulsion requires an emulsification tank, which occupies a large cost in production.
Chinese Patent Publication No. CN101802117A, date of publication: August 11, 2008, invention name "polishing product without volatile components", the application discloses a polishing product containing 20-60% wax group 20-60% non-aqueous non-volatile liquid components, and 1-40%, preferably 5-15%, fat components, preferably fatty acids, mainly in the form of small flake solids in paste form, not suitable for preparation wet wipes
The existing technology is generally used directly for the care of leather products. It is used as a wet wipe concentrate. There are two main disadvantages: one is that the formula does not consider the dilution problem, and demulsification and precipitation may occur during the application process. The glazing effect is not very ideal after dilution

Embodiment 1

[0055] The preparation method of No. 1 to No. 12 concentrated solution is: ① Mix A) and B) components and heat to a molten state, keep it warm for 20-60 minutes, and use it as an oil phase; ② Heat C) to 80-90°C, Keep warm for 20-60 minutes and use it as the water phase; ③After the emulsification tank is heated to 80°C, add the oil phase to the emulsification tank, then slowly add 1 / 3 of the water phase into the emulsification tank, and then pump the remaining water phase into the emulsification tank. Stir at high speed, homogenize for 10-40 minutes, emulsify completely, keep warm for half an hour, cool down to 40°C, add component D) and continue stirring for 5-10 minutes.

Embodiment 2

[0062] The stability of the diluent, after diluting the No. 1 to No. 12 concentrated solution in Example 1 with cold water (11°C) 5 to 30 times, observe whether there is stratification in 24 hours, the results are shown in Table 2, and it can be seen that the diluent of the concentrated solution of the present invention There is no delamination phenomenon, and it has good stability.

Embodiment 3

[0065] Embodiment 3 glazing nursing evaluation

[0066] The evaluation adopts the sensory evaluation method. After diluting the concentrated solution No. 1 to No. 12 in Example 1 by 5, 10 and 20 times, impregnated with a spunlace non-woven fabric (60% cotton content), the water content is controlled at the level of the non-woven fabric. 300%-400% of the weight, spare.

[0067] Use this wet towel to wipe the designated area on the leather sofa, the area is 10cm×10cm, and the evaluation scores are 25, 50, 75 and 100, which in turn indicate that the glazing care effect is very poor, average, good, and very good. The number of evaluations is 5 people, and the average value is taken after the test, and the results are shown in Table 3.

Abstract

The invention discloses a concentrated solution for preparing leather polish and care products, and an application. The concentrated solution can be dissolved rapidly in cold water, is stable without any layer-built in the cold water, has good polish and care functions when being diluted no more than 30 times, and is very suitable for the production application of the leather polish and care products such as functional wet wipes and the like. The concentrated solution facilitates addition, without any emulsification process.

Description

technical field [0001] The invention relates to a concentrated liquid of leather glazing care products and its application, which is mainly used for the preparation of leather glazing care products. Background technique [0002] At present, the leather glazing care products on the market mainly include: one is leather glazing care spray, which is mainly used for glazing care of leather clothes, leather sofas and automobile leather interiors; the other is leather glazing care solution, which uses a care brush Or other soft cotton cloth to wipe leather products; there is also a leather polishing care wet wipe, which mainly uses impregnating liquid with glazing care effect, uses non-woven fabric as a carrier, and wipes leather products. It is a one-time use product. Leather care polish sprays and polish liquids are limited in their scope of use due to their inconvenient portability. Wet wipes have developed rapidly as a disposable consumer product in recent years. Its functio...
