1. Environmentally friendly lubricants for printing inks
Ink lubricant refers to the material that can reduce the viscosity or stickiness when added to the ink, reduce the problems of paper pulling and powder falling, and improve the uniformity of ink distribution. The lubricants used in traditional ink production will more or less produce some pollution, which is not suitable for the needs of today’s market.
CN201610693395.7 provides an environmentally friendly lubricant for printing ink with good use effect and simple processing. The following technical scheme is used to realize: an environmentally friendly lubricant for printing ink, made of the following components in parts by weight: 40-60 parts of methacrylic acid, 5-10 parts of emulsifier, 4-8 parts of white peak wax, cinnamon 2-3 parts of aldehyde diethyl acetal, 2-3 parts of defoamer, 6-10 parts of zein, 0.4-0.6 parts of kraft powder, 0.1-0.2 parts of paeonol, 0.4-0.6 parts of Sophora flavescens gel, 0.4-0.6 parts of alanine, 3-5 parts of dihydroxyacetone, and 1-3 parts of nano-bamboo charcoal powder.
The preparation method is: stir methacrylic acid and emulsifier, add white peak wax, heat until the white peak wax dissolves, then add zein, stir and mix for 0.5 hours, then add kraft powder, paeonol and nano-bamboo charcoal powder, heat up to 70 -80°C, react for 2 hours, neutralize to pH 7, add cinnamaldehyde diethyl acetal, defoamer, flavescens gel, alanine and dihydroxyacetone while stirring, and finally start rapid stirring (1440r/ min), to obtain a milky product for production use.
The production process of the invention is simple, and by adding ingredients such as zein, White beeswax, and nano-bamboo charcoal powder, the product has excellent lubricating performance and good fusion degree. The beneficial effects of the present invention are: the present invention uses zein in the production of environmentally friendly lubricants for printing inks, which is the first in China; the lubricant prepared by the method has excellent characteristics such as gelation, oxidation resistance and lubricity.
2. Environmentally friendly detackifier for printing ink
Detackifier refers to the material that can reduce the viscosity or viscosity when added to the ink. It is a waxy paste mixture with a loose and lubricated texture. After adding an appropriate amount of ink, it can reduce the viscosity of the ink, reduce the problems of paper pulling and powder dropping, and It can improve the uniformity of ink distribution. The detackifiers used in traditional ink production will more or less cause some pollution, which is not suitable for the needs of today’s market. CN201510185217.9 provides an environmentally friendly detackifier for printing inks with good adhesive effect and no pollution.
It is made of the following components in parts by weight: 5-10 parts of petrolatum, 1-3 parts of ethyl paraben, 1-3 parts of White beeswax, 4-6 parts of cinnamaldehyde diethyl acetal, 15 parts of methylhexyl cinnamaldehyde -20 parts, 50-60 parts of linseed oil, 1-2 parts of neomycin sulfate, 5-10 parts of aluminum distearate, 4-6 parts of clove oil, 4-6 parts of silicone oil, 1- 3 copies. The preparation method is as follows: 1) First, put the prepared vaseline, ethylparaben, white peak wax, cinnamaldehyde diethyl acetal, methylhexyl cinnamaldehyde, linseed oil, clove oil and silicone oil into the reaction kettle; 2) heat up To 170+5°C, keep warm for one hour, start to put in aluminum distearate, neomycin sulfate and methyl methacrylate, raise the temperature to 180+5°C, stir evenly, and then leave the kettle.
Beneficial effects of the present invention: adding the present invention to the ink can increase the brightness of the ink, improve the wettability, improve the ink property, increase the printing speed, reduce the viscosity, and be environmentally friendly and pollution-free.
3. Used to prepare a natural moisturizing lipstick for summer
CN201811419679.2 proposes a formula of natural moisturizing lipstick for summer. The raw materials include the following parts by weight: 12-16 parts of natural beeswax, 2-6 parts of carmine, 1-5 parts of pearl powder, 1-5 parts of mica powder, 3-7 parts of glycerin, 6-10 parts of olive oil, White 12-16 parts of beeswax, 1-5 parts of rose pollen, 0.2-0.6 parts of essence, 9-17 parts of jojoba oil.
The beneficial effect of the present invention is: by putting carmine, rose pollen and jojoba oil raw materials into the beaker for heating and stirring and mixing, and adding pearl powder and mica powder in the process of stirring, through pearl powder and mica powder It can make enough friction between cochineal and rose powder to make the lipstick mixture mix more evenly; heat and melt natural beeswax, glycerin, olive oil and White beeswax in a beaker, and then add after the waxy ingredients are mixed The mixture of essence, pearl powder and mica powder, and the waxy raw materials are fully ground and mixed, so that the waxy raw materials and essence are mixed evenly under the stirring and heating action of the electromagnetic heating stirrer, and when the waxy raw materials are stirred, the lipstick color The mixture is in the state of disassembly and stirring, and the production time is reasonably used to make the lipstick mixture fully mixed after the lipstick mixture is mixed with the waxy raw material.
By increasing the heating temperature and reducing the rotation speed, the lipstick stock solution can be mixed slowly and fully to prevent the lipstick stock solution from spilling due to excessive rotation speed. The lipstick produced contains pearl powder and mica powder, so it is easy to apply on the lips and has more Three-dimensional effect, the waxy and oily ingredients contained in the lipstick can improve the texture of the lipstick, effectively keep the lips moist, not easy to fade, suitable for use in high temperature seasons.
4. For the preparation of tacrolimus ointment
The base of traditional tacrolimus ointment is liquid paraffin, White beeswax, white petrolatum and paraffin, and the solvent is propylene carbonate; the bases in the prescription are all non-polar solvents, and the density is less than 1g/ml; and propylene carbonate is extremely Sexual solvent, density greater than 1g/ml. This prescription compatibility makes the tacrolimus ointment easy to separate the solvent in the high temperature and freeze-thaw cycle test, sinking to the bottom, and it is difficult to obtain a uniformly distributed pharmaceutical preparation.
CN201210356770.0 provides a new preparation method, through which not only uniformly distributed pharmaceutical preparations can be obtained, but also impurities can be reduced, and the storage time of products can be improved. Methods include:
1. Weigh the purified tacrolimus, White beeswax, liquid paraffin, paraffin, white petrolatum, propylene carbonate and propylene glycol, and their mass ratio is 1:30:40:30:520:10 in sequence: 10; 2. Mix white beeswax with liquid paraffin and paraffin, heat and melt, and mix evenly to obtain a mixed solution I, which is kept at 70°C for later use; 3. Heat and melt white petrolatum to obtain a white petrolatum solution, which is kept at 70°C for later use; 4. Mix propylene glycol and propylene carbonate uniformly at a ratio of 1:1 to obtain a mixed solution 2; 5. Dissolve tacrolimus in a mixed solution of propylene glycol and propylene carbonate to obtain a mixed solution 3, and keep it warm at 70°C for later use; 6. Put the mixed solution 3 was dispersed in white vaseline solution to obtain mixed solution 4, and then mixed solution 4 was added to the above mixed solution Ⅰ, stirred at 70°C for 10 minutes, cooled down, and continued to stir until solidified into a paste.
Beneficial effects: After the process is changed, various quality indexes of the product can be controlled within the range of the national drug standard, and the curative effect and stability of the drug can be consistent with that of the imported drug. After the prescription process is improved, all production requirements can be produced with domestic equipment, which can greatly reduce production costs and achieve rapid industrialization.
