A paintable decompression brittle shell mastic and method of making same

Abstract

The application provides a paintable decompression brittle shell mastic and a preparation method thereof. The paintable decompression brittle shell mastic comprises a mastic component and a brittle shell component. The mastic component comprises an adhesive 15-60% by mass percentage. The brittle shell component comprises an ink absorbent 2-50% by mass percentage. The mastic component and the brittle shell component are easy to separate. The brittle shell component is easy to be peeled and cleaned from the mastic component. The user is not easy to be stuck when continuing to use the mastic component. The decompression effect of the mastic component is improved. Since the brittle shell component is not easy to be bonded with the dried mastic component, a gap is easy to be generated between the inner surface of the brittle shell component and the outer surface of the mastic component. Therefore, the sound of the brittle shell component when being crushed is more crisp. The anti-sticking agent after shaping can gradually migrate and enrich on the surface of the mastic component. The anti-sticking agent and the moisturizing agent can play a synergistic effect, maximally prevent the volatilization of the mastic moisture, ensure the softness and durability of the mastic component, and the hand feeling is more delicate. The paintable decompression brittle shell mastic can be freely painted.

Description

Technical Field

[0001] This invention relates to the field of decompression toy technology, specifically to a paintable decompression brittle clay and its preparation method. Background Technology

[0002] There are many types of clay toys, the most common being crystal clay, foaming clay, pearlescent clay, and modeling clay. In recent years, a type of decompression-resistant, crispy clay with a brittle outer shell and a soft inner shell has also appeared on the market. For example, Chinese patents with application numbers CN202111649863.8 and CN202111646705.7 disclose a decompression-resistant, crispy clay composition and its preparation method, which has certain reference value. The decompression-resistant, crispy clay composition includes a clay component and a crispy shell component. The clay component includes 6-30% adhesive, 1.5-25% humectant, 0.1-10% preservative, and the balance being solvent. The crispy shell component includes a film-forming agent. The crispy shell component is disposed on the outer surface of the clay component, thus obtaining the decompression-resistant, crispy shell clay.

[0003] In existing technologies, after decompressing and crushing the brittle clay, the brittle shell and clay tend to mix together. The brittle shell is also sharp and can be prickly, which affects the playability of the clay. In addition, the brittle shell offers limited play options and lacks DIY fun. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a paintable decompression-resistant brittle clay and its preparation method.

[0005] This application discloses a paintable, decompression-resistant, brittle shell putty comprising: a putty component and a brittle shell component. The putty component, by mass percentage, includes 15%-60% adhesive, 1%-15% humectant, 0.1%-8% anti-sticking agent, 0.1%-8% preservative, and the balance being water. The anti-sticking agent includes at least one of silicone oil, wax, and petrolatum. The brittle shell component, by mass percentage, includes 45%-95% film-forming agent, 2%-50% ink absorber, and 0.2%-5% functional additives. The ink absorber includes at least one of fumed silica, precipitated silica, kaolin, diatomaceous earth, bentonite, silica fume, starch, and aluminum hydroxide.

[0006] Preferably, the anti-sticking agent is dimethyl silicone oil and liquid paraffin.

[0007] Preferably, the mass ratio of dimethyl silicone oil to liquid paraffin is 5:(1-15).

[0008] Preferably, the ink absorber includes fumed silica and hydrated aluminum hydroxide.

[0009] Preferably, the mass ratio of fumed silica to hydrated aluminum hydroxide is 10:(1-50).

[0010] Preferably, the fineness of the hydrated aluminum hydroxide is 2000-10000 mesh.

[0011] Preferably, the average particle size of fumed silica is 1-20 micrometers.

[0012] Preferably, the brittle shell component is disposed on the putty component.

[0013] Preferably, the brittle shell component and the putty component are independent of each other.

[0014] This application discloses a method for preparing paintable, decompressible, brittle shell putty, comprising the following steps:

[0015] The clay component and the liquid brittle shell component were prepared separately.

[0016] The brittle shell component is coated onto the outer surface of the clay component and dried to obtain a paintable and decompressible brittle shell clay; or, the clay component and the liquid brittle shell component are packaged separately to obtain a paintable and decompressible brittle shell clay.

[0017] The beneficial effects of this application are as follows: By adding an anti-sticking agent to the clay component, after the user crushes the paintable, decompressible, and brittle clay, firstly, the clay component and the brittle shell component are easily separated. The anti-sticking agent reduces adhesion to the surface of the clay component, making it easier to peel and remove the brittle shell component. Users are less likely to experience sharp edges when continuing to use the clay component, thus improving its decompression effect. Secondly, because the brittle shell component does not easily adhere to the dried clay component, gaps easily form between the inner surface of the brittle shell component and the outer surface of the clay component, thus reducing the brittle shell... The sound when the components are crushed is crisper. Furthermore, the anti-sticking agent gradually migrates and accumulates on the surface of the clay components after shaping. The anti-sticking agent and the moisturizer work synergistically to prevent the evaporation of moisture from the clay to the maximum extent, ensuring the softness and durability of the clay components, while also making the texture more delicate. Adding ink absorbent to the brittle shell components allows for painting on its surface with watercolor pens, oil paint pens, crayons, etc., after the brittle shell components have dried. This means that the outer surface of the decompression brittle shell clay can be freely painted and colored, increasing the DIY fun of painting decompression brittle shell clay. Detailed Implementation

[0038] In practical applications, the clay component and the brittle shell component can be packaged separately.

After drying, it forms a paintable and decompression-relieving brittle shell clay, which adds another DIY option. Alternatively, the brittle shell component can be applied directly to the clay component to form a finished paintable and decompression-relieving brittle shell clay.

[0039] Thus, by adding an anti-sticking agent to the clay components, after the user crushes the paintable, decompressible, and brittle clay, firstly, the clay components and the brittle shell components are easily separated. The anti-sticking agent reduces the stickiness on the surface of the clay components, making it easier to peel and remove the brittle shell components. Users are less likely to experience sharp edges when continuing to use the clay components, improving the decompression effect. Secondly, because the brittle shell components do not easily adhere to the dried clay components, gaps easily form between the inner surface of the brittle shell components and the outer surface of the clay components. Therefore, the brittle shell components are less likely to be crushed. The sound when it breaks is crisper. Furthermore, the anti-sticking agent gradually migrates and accumulates on the surface of the clay components after shaping. The anti-sticking agent and the moisturizer work synergistically to prevent the evaporation of moisture from the clay to the maximum extent, ensuring the softness and durability of the clay components, while also making the texture more delicate. Adding ink absorbent to the brittle shell components allows for painting on its surface with watercolor pens, oil paint pens, crayons, etc., after the brittle shell components have dried. In other words, the outer surface of the decompression brittle shell clay can be freely painted and colored, increasing the DIY fun of painting decompression brittle shell clay.

[0040] Using dimethyl silicone oil and liquid paraffin as anti-sticking agents results in better flowability and anti-sticking effect. The anti-sticking agent exhibits optimal performance when the mass ratio of dimethyl silicone oil to liquid paraffin is 5:(1-15).

[0041] Fumed silica and hydrated aluminum hydroxide are used as ink absorbers. Both fumed silica and hydrated aluminum hydroxide are porous materials with high porosity, which can quickly absorb and fix colored pen ink. Consumers can use watercolor pens, oil paint pens or crayons to draw freely, and the colors are bright and not easy to smudge. When the fineness of hydrated aluminum hydroxide is 2000-10000 mesh, or the average particle size of fumed silica is 1-20 micrometers, or the mass ratio of fumed silica to hydrated aluminum hydroxide is 10:(1-50), the ink absorption and ink fixing effect of the ink absorber is better.

[0113] In conclusion, adding an anti-sticking agent to the clay component makes it easier for users to separate the clay and the brittle shell components after crushing the paintable decompression clay. The brittle shell component is easier to peel off and clean from the clay component, making it less likely to prick the user's hands when using the clay component, thus improving the decompression effect. Secondly, because the brittle shell component does not easily stick to the dried clay component, gaps easily form between the inner surface of the brittle shell component and the outer surface of the clay component, resulting in a crisper sound when the brittle shell component is crushed. Furthermore, the anti-sticking agent gradually migrates and accumulates on the surface of the clay component after shaping. The anti-sticking agent and the moisturizer work synergistically to prevent the evaporation of moisture from the clay to the maximum extent, ensuring the softness and durability of the clay component, while also making the feel more delicate. Adding an ink absorbent to the brittle shell component allows for painting on its surface with watercolor pens, oil paintbrushes, crayons, etc., after the brittle shell component dries. This means that the outer surface of the paintable decompression clay can be freely painted and colored, increasing the DIY fun of paintable decompression clay.

[0114] Using dimethyl silicone oil and liquid paraffin as anti-sticking agents results in better flowability and anti-sticking effect. The anti-sticking agent exhibits optimal performance when the mass ratio of dimethyl silicone oil to liquid paraffin is 5:(1-15).

[0115] Fumed silica and hydrated aluminum hydroxide are used as ink absorbers. Both fumed silica and hydrated aluminum hydroxide are porous materials with high porosity, which can quickly absorb and fix colored pen ink. Consumers can use watercolor pens, oil paint pens or crayons to draw freely, and the colors are bright and not easy to smudge. When the fineness of hydrated aluminum hydroxide is 2000-10000 mesh, or the average particle size of fumed silica is 1-20 micrometers, or the mass ratio of fumed silica to hydrated aluminum hydroxide is 10:(1-50), the ink absorption and ink fixing effect of the ink absorber is better.
