Problems solved by technology

And the liquid shoe polish that takes plant source coloring agent as the main raw material on the market is also less or has no report
[0003] At present, most of the pigments used in the black liquid shoe polish on the market are chemically synthesized dyes or extracts of chemical industrial waste, which are likely to cause harm to the environment and human body. Therefore, it is very important to develop a plant-derived dye under this background. Significance

Embodiment 1

[0022] Concretely prepare a liquid shoe polish prepared by extracting ginkgo ketone and extracting paste-like scraps and a preparation method thereof. The product preparation process and steps are as follows: filter the ginkgo leaf paste-like scrap raw materials with a filter or filter with a 300-mesh screen to remove the granular impurities, and then adjust the pH value to 6 with an appropriate amount of dilute HCl or NaOH to prevent the accumulation of melanin precipitation.

[0023] The filtrate is heated and concentrated, and the water and some volatile substances are evaporated to dryness to ensure that some toxic and odorous substances are removed until the water is evaporated to dryness. Gently stir during the steaming process, mix evenly, and always control the temperature at a slightly higher temperature of 100°C to obtain a black viscous and bright mixed liquid.

[0024] Add 2% solid paraffin and 2% beeswax to the obtained black viscous bright mixed liquid in turn, s...

Embodiment 2

[0030] Concretely prepare a kind of liquid shoe polish prepared from ginkgo ketone extraction paste waste and the preparation method, the product preparation process and steps are as follows:

[0031] Use a filter or 200-mesh sieve to filter the ginkgo leaf paste leftover raw material to remove granular impurities, and then adjust the pH value to 8 with an appropriate amount of dilute HCl or NaOH to prevent the accumulation of melanin precipitation.

[0032] The filtrate is heated and concentrated, and the water and some volatile substances are evaporated to dryness to ensure that some toxic and odorous substances are removed until the water is evaporated to dryness. Gently stir during the steaming process, mix evenly, and always control the temperature at a slightly higher temperature of 100°C to obtain a black viscous and bright mixed liquid.

[0033] Add 3% solid paraffin and 3% beeswax to the obtained black viscous bright mixed liquid in turn, stir gently and heat until me...

Abstract

The invention relates to a liquid shoe polish prepared by ginkgo leaf ketone extracted paste residual wastes and a preparation method thereof. The shoe polish comprises the following raw materials by mass percent: 60-80% of filtered and suction filtered ginkgo leaf ketone extracted paste residual wastes, 0.5-3% of solid paraffin, 0.5-3% of beewax, 0.5-15% of liquid paraffin, 1-15% of turpentine, 0.5-1% of surfactant, 0.5-1% of emulgator, 0.5-1% of silicon oil, 0.05-1% of natural essence, and 0.05-1% of glycerinum. The invention also relates to the preparation steps of the liquid shoe polish. The shoe polish has the characteristics and advantages of using the natural plant source ginkgo leaf residual wastes as the black raw material, having no dyes, no toxicity, and no odor, being bright and clean, good in polishing performance, and environment-friendly, having a simple preparation process and low cost, efficiently using the ginkgo leaf residual wastes, turning the waste into wealth, firmly coloring, being bright in color and luster, softening and protecting the leather, repairing shallow marks, being mould-proof and anti-microbial, being not prone to have dust, and being light-resistant, heat-resistant and good in stability.

Description

technical field [0001] The invention provides a liquid shoe polish prepared from ginkgo ketone extraction paste waste and a preparation method thereof, belonging to the technical field of daily-use chemicals, and belonging to the specific technical field of research and development and production of shoe polish. Background technique [0002] Shoe polish is a protective and polishing agent applied on the surface of leather shoes and leather. It has the functions of waterproofing, protecting leather, enhancing the gloss of leather surface, cleaning, beautiful and adding color. It is widely used in daily life. Shoe polish is classified according to its structure, including solvent-based hard paste, emulsified ointment and liquid type. The first two are traditional products, and liquid shoe polish is a new popular product in China. Liquid shoe polish has the characteristics of self-brightening without wiping, easy to carry, time-saving, etc., and easy to apply and wipe, and is d...
