Description

Spraying method and application of water-based ink
Technical Field
The invention belongs to the technical field of ink spraying, and particularly relates to a spraying method of water-based ink and application thereof.
Background
VOCs are volatile organic compounds (VOLATILE organic Compounds), VOCs in the ordinary sense are commanding organic compounds; VOC in the environmental protection meaning refers to volatile organic compounds which are active in nature and can generate harm. The oily ink adopts an organic solvent as a diluent, has high VOC content and is not environment-friendly. The Water-based color ink (Water-based ink) is mainly prepared by carrying out compound grinding processing on Water-soluble resin, organic pigment, solvent and related auxiliary agents, wherein the solvent is mainly deionized Water, so that the VOC emission is basically 0.
The oily silk-screen printing ink covered on the back of the 3C electronic product glass is replaced by the water-based spraying printing ink, so that the low VOC emission standard is better met, and the requirement of environmental protection is better met. However, since the surface tension of the water-based color ink is higher at the glass edge than at other positions, oil is very likely to accumulate at the edge such as the hole site during spraying. In order to solve the above problems, the following spraying process is often adopted in the related art:
firstly, preparing a membrane: performing transfer printing on the PET film; (a Z-shaped transfer printing glue line is dripped on the membrane by adopting a needle head, the grain surface of the membrane is covered on the transfer printing glue, then a roller is adopted to roll on the membrane to ensure that the transfer printing glue is uniformly distributed, and then 15-1800 mj/cm is adopted2Curing the transfer printing glue by using the energy; then plating optical plating on the transferred product, wherein the optical plating is usually carried out by evaporating materials such as silicon dioxide, phosphorus pentoxide and the like so as to carry out physical deposition on the surface of the membrane to a nanometer thickness; printing black cover on the product after the optical plating, and printing a black bottom with the thickness of 7-8 mu m by adopting 420-mesh gauze; forming the printed diaphragm into the size and shape of the rear cover of the mobile phone by a CNC (numerical control milling machine);
and then processing the glass cover plate: AF spraying (Anti Finger Print) is carried out on the front surface of the glass (baking is carried out for 30 minutes at 150 ℃); spraying oily side covering ink (baking at 150 ℃ for 30 minutes);
the diaphragm is combined with the glass cover plate: coating optical cement on the front surface of the diaphragm, attaching the diaphragm to a glass cover plate, and placing the glass cover plate into a vacuum defoaming machine for defoaming; and finally, cleaning, packaging and delivering.
The process can spray oil paint on the side edge after the cover plate is pasted with the film, so that the scheme also has more organic solvents and is not environment-friendly. In addition, the membrane is required, and the procedure is complicated.

Therefore, the invention provides a spraying method of water-based ink, which can solve the problem that oil is accumulated on the edge and the hole of a substrate by the water-based ink, shorten the spraying process and reduce the cost.
A second aspect of the present invention provides a 3C electronic product comprising the product prepared by the above spray coating method.

s1, arranging a water-based photosensitive protective ink layer in a protective area on the surface of a base material B;
s2, carrying out AF spraying on the non-protection area of the surface B of the base material and the surface A of the base material;
and S3, removing the water-based photosensitive protective ink layer, and arranging a water-based color ink layer in the protective area on the surface of the substrate B.
According to a preferred embodiment of the present invention, at least the following advantages are provided:
(1) in the spraying method provided by the invention, the base material is sprayed by the water-based color ink, and the coating effect (including appearance and adhesive force) which is equivalent to or even better than that of the oil-based ink can be obtained, so that the use of the oil-based ink can be reduced, and the VOC emission can be reduced.
(2) Compared with the traditional spraying process needing membrane assistance, the spraying method provided by the invention has the advantages of simpler process and higher yield.
(3) According to the invention, the water-based photosensitive protective ink layer is arranged in the protective area on the surface B, so that the protective area is prevented from being polluted during subsequent AF spraying (fingerprint-proof spraying, generally, a thin film technology that AF liquid medicine is uniformly sprayed on the surface of a product by high pressure, and the adhesive force of water-based color ink on the surface is low), and the condition that the adhesive force of the water-based color ink layer is unqualified is avoided; and because the aqueous photosensitive protective ink layer is arranged in the protective area, the hole positions and the edges of the non-protective area can be more fully sprayed during AF spraying, and the problem of oil accumulation of aqueous color ink in the non-protective area is avoided.
In some embodiments of the present invention, in the spraying method, the substrate material includes at least one of glass and plastic.

In some preferred embodiments of the present invention, in step A3, the number of times steps a1 to a2 are cycled is 2 times.
The reason for the recycling of steps A1-A2 is that: after the single layer spray coating is cured, a pinhole problem can occur in the developing process; if the cycle is repeated once and the thickness of the coating is increased in step a1, a serious edge-stacking problem (edge oil accumulation) occurs due to capillary phenomenon.
