Problems solved by technology

Grinding flat glass with emery is relatively easy to operate, but for glass containers such as bottles, it is more difficult to achieve uniform grinding on the surface
If chemical treatment is used, the process is complex and requires the use of a large amount of acid, alkali, organic solvent, etc., which may cause environmental pollution

Embodiment 1

[0064] Preparation of plant acid:

[0065] Take the fallen and residual fruits of fresh lemons, wash them, squeeze the juice with a juicer, and get lemon juice A by coarse filtration, soak the residue in pure water with 1.5 times the mass of the lemon residue for 5 hours, and then coarsely filter to get the filtrate, and the filtrate is mixed with lemon After the juice A is combined, the clarified lemon juice B rich in citric acid is obtained through fine filtration, that is, the plant acid solution;

Embodiment 2

[0067] Cleaning of cosmetic glass bottles:

[0068] Put the newly purchased unused cosmetic glass bottle in the plant acid solution, soak it for 6 hours, wash to remove the putty, rust spots and other impurities on the surface, drain the plant acid solution in the bottle, and rinse it with clean water several times Bottle, finally rinse with pure water to completely remove residual plant acid, and dry the water.

Embodiment 3

[0070] Cosmetic glass bottle surface pretreatment and electrostatic spraying:

[0071] (1) Preparation of dilute solution of silane coupling agent: take amino functional silane coupling agent KH-470, dissolve it in absolute ethanol, configure it into a 1% dilute solution, and place it in the room temperature raw material box of an intelligent automatic spraying device;

[0072] (2) Put the cleaned and dried cosmetic glass bottle on the conveyor belt of the intelligent automatic spraying device, turn on the motor, and the manipulator grabs the cosmetic glass bottle on the conveyor belt and puts it in the spray box. The silane coupling agent solution in the raw material box Through the action of the liquid pump, it reaches the nozzle and sprays evenly on the surface of the cosmetic glass bottle;

[0073] (3) After the surface is evenly sprayed, turn off the liquid pump through the central controller to stop spraying, open the oven, and quickly dry the cosmetic glass bottle, so t...

Abstract

The invention discloses an electrostatic powder spraying method for a cosmetic glass bottle surface. The electrostatic powder spraying method comprises the following steps: S1, bottle washing: washing and drying the surface of the cosmetic glass bottle. S2, surface pretreatment: spraying a silane coupling agent solution on the surface of the cosmetic glass bottle; and S3, electrostatic spraying: performing electrostatic powder spraying on the cosmetic glass bottle subjected to surface pretreatment, and baking and curing. The cosmetic glass bottle treated by the method provided by the invention has a rough surface and an opaque frosted texture in appearance, has a hazy mystery feeling when being used for containing cosmetics, meets the current popular demand, and is convenient to use, safe and reliable, and the bottle body is not easy to slip off when the cosmetics are used.

Description

technical field [0001] The invention relates to an electrostatic powder spraying method on the surface of a cosmetic glass bottle, in particular, it involves pre-spraying a layer of silane coupling agent on the outer surface of a smooth cosmetic glass bottle, and then electrostatically spraying resin powder, such as epoxy resin, polyurethane Resin, acrylic resin, etc. Background technique [0002] Glass bottles have high transparency and corrosion resistance, and will not change the material properties when in contact with most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is high, heat-resistant, clean, and easy to clean. Glass bottles are widely used as packaging materials, mainly for alcohol, beverages, condiments, cosmetics, etc. [0003] Generally, it is recommended not to store cosmetics in places exposed to direct sunlight or exposure to the sun, as this will accelerate deterioration and shorten the shelf life, especia...
