Embodiment 1
[0093] A watch case is mainly prepared from the following raw materials in parts by mass:
[0095] In terms of mass percentage, the antioxidant composition is: 20% of 2,6-di-tert-butyl-4-methylphenol, 30% of antioxidant 2246 and 50% of antioxidant 1010;
[0096] The gloss agent is erucamide.
[0097] The preparation method of the watch case comprises the following steps:
[0098] (a) plant fiber is pulverized in pulverizer;
[0099] (b) refine the crushed plant fibers in a refiner, and refine them into 0.2-0.4MM scraps for use;
[0106] A watch case is mainly prepared from the following raw materials in parts by mass:
[0107] 53 parts of plant fiber, 30 parts of melamine resin, 4 parts of stearyl alcohol, 0.2 part of antioxidant, 0.20 part of gloss agent and 0.7 part of pigment.
[0108] Described antioxidant is with embodiment 1;
[0109] The gloss agent is erucamide.
[0110] The preparation method of the watch case is the same as in Example 1.

Abstract
The invention relates to the technical field of plantfiber material watches, and particularly relates to a watchcase and a preparation method thereof. The watchcase is mainly prepared from the following raw materials in parts by mass: 50 to 60 parts of plant fibers, 25 to 42 parts of melamine resin, 1 to 5 parts of stearyl alcohol, 0.15 to 0.45 part of an antioxidant, 0.15 to 0.25 part of a glossagent and 0.5 to 0.9 part of pigment. The production cost of the watchcase is obviously lower than that of a traditional metal, ceramic and jade watch, the traditional metal, ceramic and jade watch can be replaced, a large number of rice husks, corncobs, peanut shells and the like discarded in rural areas can be effectively utilized, waste is turned into wealth, and atmospheric pollution caused by burning of plant fibers is effectively prevented. The produced watch is good in natural texture, clear and gorgeous in lines, environment-friendly, waterproof, flame-proof, light in weight and highin strength.
Description
technical field [0001] The invention relates to the technical field of plant fiber watches, in particular to a watch case and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the development of economy, my country pays more and more attention to environmental protection. Traditional watch cases are generally made of plastic, metal and ceramics, which will cause serious pollution to the ecological environment during processing and polishing. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] An object of the present invention is to provide a watch case, which has the characteristics of good natural texture, clear and gorgeous lines, environmental protection, waterproof, flameproof, light weight and high strength through the coordination and cooperation of various components. [0005] Another object of the present invention is to provide a method for preparing the wat...
