A filled gel having a suspending function

Abstract

This invention discloses a filler gel with suspension and dispersion function, comprising the following components in the indicated weight ratios: 1-4% glitter powder; 1.1-2.2% sodium polyacrylate; 0.1-0.4% glycerol; 1-1.5% water-soluble calcium salt; and the remainder being water. Due to the SEBS of the filler's outer layer, commonly used chemical substances cannot be used to improve the filler's dispersion stability. This invention utilizes the quaternary ammonium present in the UV layer to significantly improve the dispersion stability of large-particle glitter powder within the filler without affecting the color of the glitter powder. The addition of water-soluble calcium salt also greatly enhances the dispersion stability.

Description

Technical Field

[0001] This invention relates to the field of chemicals for filling, and in particular to a filling gel with suspension and dispersion function. Background Technology

[0002] The outer shell of soft toy products can be made into various shapes, such as fruit shapes, animal shapes, sphere shapes, anime and cartoon shapes, etc. The interior is filled with stuffing material, which includes glitter powder.

[0003] Glitter powder, also known as glitter flakes or glitter powder, can be produced in particle sizes ranging from 0.004mm to 3.0mm. Its shapes include squares, hexagons, rectangles, and rhombuses. Glitter powder color series include holographic silver, holographic gold, holographic colors (including red, blue, green, purple, peach, red, and black), silver, gold, and multicolored (red, blue, green, purple, peach, red, and black) iridescent series. Each color series is coated with a protective layer, resulting in a bright luster and some resistance to mildly corrosive chemicals and temperature variations.

[0004] The filling materials used in traditional soft toys on the market mainly fall into the following three categories:

[0005] 1. Polyvinyl alcohol or guar gum, with borax. Disadvantage: Contains boron, cannot suspend glitter powder for extended periods.

[0006] 2. Triethanolamine and Carbomer. Disadvantages: The product lacks stretchability after processing and can only achieve a simple extrusion effect.

[0007] 3. Maltose. Disadvantage: It will ferment over time, causing air bubbles to appear inside.

[0008] Existing soft toys lack a filling material that can stably suspend and disperse glitter powder without settling for a long time, is completely boron-free, non-toxic, safe for children, has a good feel, is elastic when squeezed, and has a stretching effect. Summary of the Invention

[0009] To overcome the aforementioned deficiencies of the prior art and solve the above-mentioned technical problems, the present invention provides the following technical solution: a filling gel with suspension and dispersion function, comprising the following components in the following weight ratio:

[0010] Glitter powder 1-4%;

[0011] Sodium polyacrylate 1.1-2.2%;

[0012] Glycerol 0.1-0.4%;

[0013] Water-soluble calcium salts 1-1.5%;

[0014] The rest is water.

[0015] The water-soluble calcium salt is selected from one or more of calcium phosphate, calcium chloride, and calcium nitrate.

[0016] The particle size of the glitter powder is 0.4mm-3mm.

[0017] The glitter powder consists of a base layer, a metal layer, a pigment layer, and a UV layer from the inside out.

[0018] The bottom layer is selected from one or more of PET, PVC, PP, PE, and PLA.

[0019] The UV layer is a coating formed by curing with ultraviolet light.

[0020] The UV layer comprises acrylate monomers, an initiator, and a polymerizable quaternary ammonium salt, wherein the mass ratio of the polymerizable quaternary ammonium salt in the UV layer is 0.01-1%.

[0021] One or more of the quaternary ammonium unsaturated monomers methacryloyloxyethyltrimethylammonium chloride, methacryloyloxyethyl-benzyl-dimethylammonium chloride, acryloyloxyethyltrimethylammonium chloride, and diallyl dimethylammonium chloride.

[0022] The outer skin of the filler is composed of SEBS and filler oil, wherein the filler oil is paraffin oil or white oil, and the weight ratio of SEBS to oil is 1:0.5 to 1:16.

[0023] The preparation method of the glitter powder is as follows:

[0024] A base film is selected, aluminum is plated on the base film and colored, and then UV coating is sprayed onto the surface by spraying. After UV curing, glitter powder is obtained by slitting and powdering.

[0025] Because the outer layer of the filler is SEBS, commonly used chemical substances cannot be used to improve the dispersion stability of the filler. This invention utilizes the quaternary ammonium present in the UV layer to greatly improve the dispersion stability of large-particle glitter powder within the filler without affecting the color of the glitter powder. The addition of water-soluble calcium salts also significantly improves dispersion stability. Detailed Implementation
