Detailed Description
The present invention will be described in further detail with reference to specific examples. It is to be understood that the following illustrative embodiments and description are only intended to illustrate the present invention, and are not intended to limit the present invention, and features of the embodiments and examples of the present invention may be combined with each other without conflict.
One embodiment of the invention provides a water-based roller coating paint for zipper sliders, which is prepared by uniformly mixing a component A, a component B and water according to a preset mass ratio before use, wherein the component A comprises the following raw materials in percentage by mass:
50-75% of water-based epoxy emulsion;
2 to 22 percent of pigment;
2-5% of a dispersant;
0.2 to 0.5 percent of flatting agent;
0.1 to 0.3 percent of defoaming agent;
5-10% of cosolvent;
the balance of water;
the component B comprises the following raw materials in percentage by mass:
80-85% of water-soluble curing agent;
5-10% of cosolvent;
the balance being water.
According to the embodiment of the invention, the component A, the component B and water are uniformly mixed according to a preset mass ratio before use to obtain the water-based zipper head roller spray coating, the water-based epoxy emulsion and the water-soluble curing agent are respectively used as main components of the component A and the component B, and the component A and the component B are formed by matching water and alcohol or alcohol ether solvents, so that the using amount of the solvents is greatly reduced, and the components are mixed and diluted by adding water during construction, so that the coating can be quickly cured and formed, can adapt to roller thermal spraying construction, and can effectively avoid the phenomenon of flower grinding when zipper heads rub against each other in the spraying process. The dispersant can play a role in wetting, dispersing and stabilizing the pigment; the leveling agent can promote the surface of the coating to be flat and uniform; the defoaming agent can enable the aqueous system to be easily defoamed; the cosolvent can promote the film formation of the coating and adjust the volatilization speed of the coating. The paint provided by the embodiment of the invention has strong economy, and particularly, through detection, compared with the traditional paint product, the paint provided by the embodiment of the invention has the advantages that the VoC content can be effectively reduced by 30-40%, the paint is green and environment-friendly, and increasingly severe environment-friendly standards can be met.
In an optional embodiment of the invention, when the components A, B and water are mixed uniformly according to a predetermined mass ratio before use, the mass ratio of the component A to the component B to the water is as follows: and (B) component: water 100: 20-25: 60-100. Since the aqueous epoxy emulsion is cured in a heterogeneous multi-phase manner, the curing of the aqueous epoxy resin and the water-soluble curing agent depends on both the stoichiometry and the diffusion rate of the curing agent among the particles of the epoxy emulsion into the emulsion, and generally, the diffusion degree of the curing agent is less than 100%. Therefore, the amount of the curing agent used in the aqueous epoxy two-component coating is less than the standard amount according to the stoichiometric method, and the excessive residual curing agent affects the results of the water washing fastness test and the phenol yellowing test of the zipper head, so that the amount of the curing agent needs to be relatively precisely limited. Through comparative study, the mass ratio of the component A, the component B and the water can be as follows: 100:20-25: 60-100, preferably 100: 25: 60.
the pigment can be titanium dioxide or organic pigment or the mixture of titanium dioxide and organic pigment. When a mixture of titanium dioxide and an organic pigment is used, the mass percentage of the organic pigment can be 2-6% and the mass percentage of the titanium dioxide is correspondingly 16-20%.

In another embodiment of the present invention, the water is deionized water or purified water. By adopting deionized water or purified water, the raw material source is wide, and the raw material cost is reduced. Moreover, water is used as a solvent to replace the traditional benzene solvents, and the VoC is not contained, so that the VoC content of the finished paint can be effectively reduced.
In another embodiment of the invention, the raw material of the component A also comprises 5-10% of filler by mass. By adding the filler into the paint, the effects of filling, rheological control, solvent release, gloss reduction and the like can be achieved through the filler, and look up with eyes wide open is obtained to improve the quality of the paint.
In another embodiment of the invention, the cosolvent in the component A and the component B is a mixed solvent of an alcohol solvent and an alcohol ether solvent, wherein the dosage ratio of the alcohol solvent to the alcohol ether solvent is 7: 3-2. By adopting the mixed solvent of the alcohol solvent and the alcohol ether solvent and reasonably proportioning the dosage ratio of the alcohol solvent to the alcohol ether solvent, the cosolvent can effectively promote the film formation of the coating and accurately adjust the volatilization speed of the coating, and the film quality and the film formation speed of the coating are effectively improved.
