Abstract
Description
Technical Field
[0001] The invention discloses a colored glaze material for handicrafts and a preparation method and application thereof, belonging to the technical field of colored glaze manufacturing. Background Art
[0002] The term "Liuli" originated in the Han Dynasty, and was later called "Lulu". At present, Liuli generally refers to glass or objects coated with glass glaze. Liuli crafts refer to handicrafts for viewing that are made of lili as raw materials and add colorants, pearlescent materials or other fillers in a molten state. With the improvement of people's living standards, people's yearning for lili handicrafts is getting higher and higher, and the requirements for the fineness of lili handicrafts are getting higher and higher.
[0003] Among glass crafts, flowers, leaves, and insects are made of glass materials to simulate naturally existing plants and animals, which is one of the more difficult types of glass crafts to make. The existing glass materials have the following problems in use: First, flowers, leaves, and insects are mostly delicate and thin parts, such as thin petals, plant leaves, vegetable leaves, and insect legs. The thinnest part can be as thin as 1 mm, which is very easy to break during the production process, and often becomes a defective product because of the breakage of a tiny thin part. Secondly, in the prior art, the temperature of molten glass continues to drop during the production process. When it drops below 900°C, it needs to be tempered. The tempering temperature is too high. Because the glass parts are too delicate, they need to be tempered repeatedly during the production process, which consumes high energy and is very easy to produce defective products. Thirdly, bubbles are easily generated during the production process of existing glass materials. If there are too many bubbles, it will have an adverse effect on the visual effects of flower, leaf, and insect glass crafts.
[0004] Currently, there is an urgent need for a glass material for handicrafts that has a low melting temperature, is not prone to cracking during the production process, has high transparency and fewer bubbles. Summary of the invention
[0005] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide a glazed material for handicrafts and a preparation method and application thereof. The glazed material for handicrafts has high transparency and good strength, and is suitable for the delicate and thin parts of petals, leaves, and insects in the production process. The handicrafts produced are thin and not easy to break, and can effectively improve the finished product rate of glazed handicrafts.

[0008] The glass material for handicrafts comprises the following components in parts by weight: 100 parts of quartz, 38 parts of sodium hydroxide, 15 parts of borax, 3.5 parts of fluorite, 4.6 parts of calcined kaolin, 1.1 parts of aluminum oxide, 2.3 parts of spodumene, 2.8 parts of sodium nitrate, 1.7 parts of sodium silicate, 2.3 parts of cryolite and 1.1 parts of a clarifier.
[0009] The clarifier is a mixture of two or three of sodium sulfate, sodium chloride and antimony trioxide.
[0010] Preferably, the clarifier is a mixture of sodium sulfate, sodium chloride and antimony trioxide in a mass ratio of 3-4:5-6:0.8-1.5. Further preferably, the clarifier is a mixture of sodium sulfate, sodium chloride and antimony trioxide in a mass ratio of 3.2:5.6:1.2.
[0011] The raw materials also include 0.1-5 parts of toner. Preferably, the toner is inorganic toner.
[0012] The preparation method of the glass material for handicrafts comprises the following steps: 1) Quartz, fluorite, calcined kaolin, alumina, spodumene and cryolite are crushed, sieved, ball-milled, dried, sieved and magnetically separated to remove iron, and powders of quartz, fluorite, calcined kaolin, alumina, spodumene and cryolite are obtained respectively; 2) mixing the powder obtained in step 1), sodium hydroxide, borax, sodium nitrate, sodium silicate and a clarifier according to weight parts, and mixing well to obtain a mixed material; 3) Heat the kiln to 1395℃-1405℃, first add 50%-60% of the mixed material by mass, keep warm and melt for 210min-240min, and stir evenly; 4) Add 20%-25% of the mixed material by mass, keep warm and continue to melt for 120min-150min, and stir evenly; 5) Finally, put all the remaining mixed materials into the kiln, seal the kiln, and continue to melt for 330min-360min; open the kiln and cool it down to 1290℃-1310℃, keep it at this temperature for 90min-120min, then seal the kiln and heat it up to 1395℃-1405° to obtain the molten glass material.
[0013] Preferably, the specific operation of step 1) is: quartz, fluorite, calcined kaolin, alumina, spodumene, and cryolite are crushed and sieved with a 60-80 mesh sieve respectively, put into a ball mill with anhydrous ethanol as a solvent at a speed of 80-100 rpm for 20-24 hours, put into an oven for drying, sieved with a 280-300 mesh sieve, and iron removed by magnetic separation to obtain powders of quartz, fluorite, calcined kaolin, alumina, spodumene, and cryolite respectively.
[0014] The application of the colored glaze material for handicrafts is in the field of making colored glaze handicrafts.
[0015] The colored glaze material for handicrafts is used in the field of making colored glaze handicrafts in the shape of flowers, leaves or insects.
[0016] Compared with the prior art, the glass material for handicrafts and the preparation method and application thereof of the present invention have the following beneficial effects: 1. The colored glaze material for handicrafts of the present invention has high transparency and good strength, and is suitable for the delicate and thin parts of petals, leaves, and insects in the production process. The handicrafts produced are thin and not easy to break, and can effectively improve the yield of colored glaze handicrafts.
[0017] Cryolite and borax can lower the melting point of glass materials, making them easier to melt. Borax can lower the firing temperature. During the melting process, it can quickly react with other ingredients to generate molten sodium silicate and cryolite as a solvent, improving the high-temperature fluidity of 600-800℃, making it easier to shape thin parts with molten glass and reducing the number of tempering times. At the same time, borax can also increase the fluidity of glass materials with sodium silicate and ice crystals, making it easier to temper and make handicrafts.
[0018] Kaolin and alumina are used as toughening and reinforcing materials, making the glass material less likely to break after cooling to room temperature. Spodumene has a small expansion coefficient and can be used as a high-temperature solvent. The high gloss of spodumene makes the surface of the glass glossy. The low expansion coefficient of spodumene can improve the shrinkage of the glass material and prevent the thin glass parts from breaking during the cooling process.
[0019] Using a mixture of sodium sulfate, sodium chloride and antimony trioxide in a mass ratio of 3-4:5-6:0.8-1.5 as a clarifier can accelerate the discharge of bubbles, reduce bubbles in glass crafts, and prevent bubbles from destroying the visual effect of using glass to simulate natural flowers, vegetables, and insects.
[0020] 2. The preparation method of the glass material for handicrafts of the present invention can reduce bubbles and improve the transparency of the glass material. The pretreatment of crushing and ball milling the raw materials in step 1) can improve the uniformity of raw material mixing. Step 1) uses magnetic separation to remove iron, effectively removes impurities in the raw materials, thereby reducing the number of bubbles in the obtained glass material and avoiding the introduction of iron elements to avoid affecting the color of the glass material. In steps 3)-5), the mixed material is added three times at 1395℃-1405℃ and melted at a constant temperature, which can make the materials in the molten glass material fully and evenly integrated, so that the strength, melting temperature and expansion coefficient of the glass material are more stable, which helps to improve the yield rate.
