Abstract
Description
Technical Field
[0001] The invention relates to office stationery technology, in particular to a new inkstone and a manufacturing process thereof. Background Art
[0002] Inkstones are one of the important categories of traditional Chinese creations, the crown of the four treasures of the study, and an ancient Chinese art design that combines aesthetics and practicality. Inkstones were born out of the need for use, and gradually evolved from being used as the main purpose to being an art piece that combines appreciation and use. In an inkstone, we can not only appreciate the beauty of the texture of the material, the creativity of the carving, and the exquisite craftsmanship of the artistic treatment, but also the inkstone is undoubtedly a carrier, accumulation and epitome of Chinese traditional culture.
[0003] However, the patents under the existing technology have the following disadvantages:
[0004] (1) The existing stone inkstone is made by inkstone carving technology, which is costly, difficult to select materials, has low utilization rate of scraps and slag, and produces too much dust. Summary of the invention
[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a new inkstone made of recycled plastic.
[0006] In order to solve the above problems, the technical solution of the present invention is: a new inkstone, comprising the following components by weight: 600-700 parts of recycled plastic, 200-300 parts of calcium carbonate, 50-100 parts of talcum powder, 10-30 parts of titanium dioxide, 5-10 parts of antioxidant, 5-10 parts of ultraviolet absorber, 5-10 parts of plasticizer, and 5-10 parts of stabilizer.
[0007] Further,
[0008] The specific component of the recycled material is polypropylene, and the polypropylene is used as the main material of the inkstone;
[0009] The calcium carbonate is used to enhance the hardness and wear resistance of the inkstone;
[0010] The talcum powder is used to improve the smoothness and molding performance of the inkstone;
[0011] The titanium dioxide is used to improve the color and hiding power of the inkstone.
[0012] Furthermore, the specific component of the antioxidant is antioxidant 1076, and the antioxidant 1076 can inhibit the thermal degradation and oxidative degradation of polymers, thereby extending the service life of these materials.
[0013] Furthermore, the specific component of the ultraviolet absorber is ultraviolet absorber UV-360. The characteristics of the ultraviolet absorber UV-360 include high temperature resistance, extraction resistance, low volatility, low migration, wide absorption range and high absorption efficiency, etc., and it is used to improve the weather resistance of the inkstone.
[0014] Furthermore, the specific component of the plasticizer is phthalate, which can lower the melting point of the recycled plastic and reduce the viscosity of the molten plastic, so that the recycled plastic is easier to flow during the processing and is easier to shape.
[0015] Furthermore, the specific component of the stabilizer is a calcium zinc stabilizer, which is non-toxic, environmentally friendly and improves the processing stability of polypropylene.
[0016] The present invention also provides a novel inkstone manufacturing process, comprising the following steps:
[0017] S1. Raw material preparation: weigh recycled plastic, calcium carbonate, talcum powder, titanium dioxide and other raw materials in proportion;
[0018] S2, stirring and mixing: first add the recycled plastic, antioxidant, ultraviolet absorber, plasticizer, stabilizer into a mixer and stir and mix, then add calcium carbonate, talcum powder, and titanium dioxide to the mixture in sequence, and stir evenly. The specific order of addition is from first to last: recycled plastic, antioxidant and other additives, calcium carbonate, talcum powder, titanium dioxide. When stirring and mixing, the raw materials need to be heated and the temperature is controlled at 170-220°C;
[0019] S3, molding: putting the mixed raw materials into the inkstone mold, and putting the mold storing the raw materials into the hot air furnace for heating and firing. First, preheat the hot air furnace to a preheating temperature between 100-150°C, and then put the recycled plastic into the furnace for preheating to prevent the plastic from cracking due to too fast temperature change. Then gradually increase the temperature to between 220-250°C and fire. The firing time is controlled within 25-30 minutes. After firing, take it out of the hot air furnace and put it on a cooling table to allow the inkstone to cool naturally and form.
[0020] S4. Polishing: Use a polishing machine to polish the formed inkstone to improve the surface smoothness.
[0021] The advantages of the present invention compared with the prior art are:
[0022] (1) The new inkstone of the present invention is made of recycled plastic polypropylene. The raw material cost of recycled plastic is usually lower than that of natural stone. Therefore, the production cost of recycled plastic inkstone is low. In addition, recycled plastic inkstone is much lighter than stone inkstone and is easy to carry and transport. The use of recycled plastic helps to reduce the environmental pollution caused by plastic waste and realize the resource utilization of waste. BRIEF DESCRIPTION OF THE DRAWINGS
