Description

Technical Field

[0001] The present invention relates to the technical field of handicrafts, and particularly relates to a high-brightness acrylic diamond and its manufacturing process. Background Art

[0002] Acrylic diamonds generally refer to handicrafts made of acrylic as the base material and formed through heating to have a diamond-like shining effect. As Figure 1 shown, it has excellent weather resistance, high strength and other properties, and is widely used in the fields of decorative walls, display cabinets, screens, jigs, stages, etc. The defect is that its price is relatively high. For this reason, some enterprises use polystyrene with a low price to replace acrylic for the production of diamond handicrafts. Comparatively speaking, the gloss of polystyrene-type diamonds is not high and needs to be improved. Summary of the Invention

[0003] To solve the above at least one technical defect, the present invention provides the following technical solutions:

[0004] The first aspect of this application document discloses a manufacturing process of a high-brightness acrylic diamond, including the following steps:

[0005] First, the color powder modification step: uniformly mix color powder, dispersant, lubricant, polyether, amide compound, coupling agent, and rubber powder;

[0006] Second, mix the color powder mixture prepared in the first step with polystyrene and make it into masterbatch;

[0007] Third, injection mold the masterbatch prepared in the second step into a substrate;

[0008] Fourth, cut the substrate according to the diamond shape.

[0009] The premixing of dispersant, lubricant, polyether, amide compound, coupling agent, rubber powder and color powder helps to improve the dispersion uniformity of color powder, brightening agent, etc. in polystyrene subsequently, and at the same time can greatly improve the gloss of the subsequently formed diamond handicrafts. Polyether and rubber powder can also play roles in toughening, heat resistance and other properties, making the cut and formed diamond handicrafts more durable.

[0010] Further, in the second step, add the color powder mixture and polystyrene to a stirring mechanism for pre-stirring and mixing, and then add the fully mixed material to a screw extruder for extrusion granulation, which helps to improve the mixing uniformity.

[0011] Further, the processing temperature during extrusion is 200 - 230 °C, and the screw speed is 520 - 580 r / min, which promotes more uniform dispersion of components.

[0012] Further, the mass ratio of toner, dispersant, lubricant, polyether, amide compound, coupling agent, and rubber powder is 10:1-3:1-2:0.2-0.5:0.6-1:0.2-0.4:10-15. Within the limited quantitative ratio, it helps to maintain the gloss and toughness of the product at a relatively high level.

[0013] Further, the mass ratio of toner to polystyrene is 5-9:100.

[0014] Further, in the first step, the amide compound is formamide, acetamide, N,N-dimethylformamide; the dispersant is one or more of ethylene bisstearamide, polyethylene wax, stearic acid, and paraffin wax; the lubricant is pentaerythritol stearate; and the rubber powder is styrene-butadiene rubber or carboxylated styrene-butadiene rubber type.

[0015] Further, it also includes an antioxidant, and the mass ratio of the antioxidant to polystyrene is 0.2-0.5:90. The antioxidant is added in the third step, which helps to improve the antioxidant performance.

[0016] The second aspect of this application document discloses a high-brightness acrylic diamond, which is prepared and formed by the above-mentioned manufacturing process.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the dispersant, amide compound, rubber powder, etc. are premixed with the toner, which helps to improve the gloss and toughness of the subsequent formed diamond handicrafts, and extends the service life of the diamond handicrafts.
