Description
Technical field
The present invention relates to a kind of hydrogel aggregate or hydrogel microcapsule production methods, belong to hydrogel aggregate or water
Gel Technology of Making Microcapsule field.
Background technique
In the prior art, in cosmetics, personal care articles, hydrogel aggregate or hydrogel microcapsule are added sometimes
Product can promote the effect of product some aspects, while also promote the aesthetics of product.
The production method of existing hydrogel aggregate or hydrogel microcapsule is general to instill water using by hydrogel solution
In, be shrunk to laminated structure using the surface tension of gel solution, for example, publication No. be CN105521747A and
The Chinese patent literature of CN105727854A, discloses a kind of production method of sheet microcapsules, plant hydrogel aggregate or
The production method of hydrogel microcapsule has the disadvantage that
1) controlled shape of microcapsules is lower, it is difficult to which the microcapsules for producing specific shape fancy are unfavorable for cosmetics
Or the aesthetics of personal care articles product.
2) microcapsules producing efficiency is lower, and cost of manufacture is higher.
3) color adaptation of microcapsules itself is weaker, for example, the effect of double-colored gradual change can not be adjusted, for
Double-colored mashed up effect also can not be adjusted easily.
Summary of the invention
The object of the present invention is to provide a kind of hydrogel aggregate or hydrogel microcapsule production methods, can be according to mold
Shape produces the hydrogel aggregate or hydrogel microcapsule of specific tessellating shapes；Producing efficiency is high, at low cost；It simultaneously can be with
Double-colored mashed up and fade effect is easily carried out to be adjusted.
The present invention takes following technical scheme:
A kind of hydrogel aggregate or hydrogel microcapsule production method, which comprises the following steps:
S1, moulding by casting: casting device horizontal to upper surface and mold with array distribution groove in top carries out water-setting
The casting of sizing material body, with the forward movement of mold after casting complete, scraper scrapes mould upper surface attached, removes the extra hydrosol
Material, and keep the hydrosol upper surface in groove horizontal；
S2, accelerate plastic: spraying divalent metal salt device carries out injection divalent metal salt fog to mould upper surface, is used for
Accelerate hydrogel solidification；
S3, demoulding are collected: mold enters in divalent metal salt water flow solidification stripper apparatus, further speeds up the water in mold
The solidification of colloidal sol Material, while power water impact demoulds hydrogel aggregate or hydrogel microcapsule, the hydrogel after demoulding
Aggregate or hydrogel microcapsule solidify the aperture outflow of stripper apparatus by divalent metal salt water flow, into sieve, are collected；
Divalent metal salt water flow is to be recycled.
Further, between step S2 and S3, further includes: step S2.1, dust suction is except inferior: removing inferior device by dust suction
Absorb the inferior object on mold 1.
Further, in step S1, there is the cavity of two kinds of different colours hydrogel Materials of storage in casting device, pass through
The hole for injecting glue of difference group is cast in downwards the upper surface of mold 1 simultaneously, attached by scraping for scraper, makes the water-setting sizing material of two kinds of colors
Body is mutually mixed, and forms gradient color.
Further, in step S1, by the position where the hole for injecting glue of change casting device, two kinds of different face are adjusted
The hydrogel Material of color is injected in the different location on mold, and then reaches and obtain different gradient color patterns and/or gradient color journey
The hydrogel capsule of degree.
Further, in step S1,3 channel upright guide rail of scraper carries out cross spacing, and under self gravitation effect
That freely lands falls in the upper surface of mold, and the mold work of different-thickness is without carrying out positioning adjusting to scraper.
Further, in step S1, mold uses the silica gel material with certain elasticity, according to table on scraper and mold
The required laminating degree in face selects the scraper of corresponding weight.
Further, in step S1, scraper 4 is designed to U-shaped structure, and scraper two sides are by the plug hole institute of casting device
Range be coated in, U-shaped opening be aligned mold moving direction it is reversed.
Further, in step S1, hole for injecting glue regular distribution on casting device is divided into flush with each other or mutually staggers
Three kinds of forms of strip slot shape of circular hole and flush with each other, and then obtain the hydrogel collection of different gradient color effects
Fit or hydrogel microcapsule.
The beneficial effects of the present invention are:
1) groove on mold can open up into the shape arbitrarily set under the horizontality of upper surface, enrich hydrogel collection
Fit or hydrogel microcapsule form, to promote the aesthetics and diversity of personal makeup nursing materials.
2) producing efficiency of hydrogel aggregate or hydrogel microcapsule greatly improves, and cost of manufacture is greatly lowered；
3) hydrogel of two groups of hole for injecting glue spray different colours of glue filling device, then scraping by scraper, to reach
Realize that the effect of double-colored hydrogel capsule further by the way that alignment and the staggeredly hole for injecting glue of two kinds of forms is arranged, reaches double
The different gradient color effect of color hydrogel capsule, enriches the diversity of product.
4) scraper is fallen on the mold of silica gel material, and mold is made to generate certain flexible deformation, is enhanced between scraper and mold
Stickiness；Scraper is fallen on mold by the way of freely landing, and can adapt to the mold of different height, adaptable；It scrapes
The weight of knife is corresponding with elastic deformation amount needed for corresponding mold, and design is simple and effective, further improves scraper operation
Reliability.
5) range at the place of two groups of hole for injecting glue of scraper U-shaped structure design covering, prevents hydrogel Material from overflowing outside mold,
It is ingenious in design.
6) demoulding of hydrogel capsule and collection mode are ingenious in design, simple and reliable；Using divalent metal salting liquid to mould
Tool is rinsed demoulding, while having both and accelerating cured effect, kills two birds with one stone.
