Problems solved by technology

The above-mentioned prior art uses stone powder or mineral powder as the main material and uses rosin as the binder. Although it overcomes the inherent defects of the asphalt target, it also has the following disadvantages: the processing temperature range of the rosin binder is relatively narrow; The flying saucer target will be cold and brittle when stored for a long time; the flying saucer target has poor heat resistance and is easy to deform during transportation; the degradation speed of the flying saucer target fragments is slow
[0007] U.S. Patent No. 5,174,581 filed on January 15, 1992 discloses a flying saucer target made of sugar, bird food and water. Its biggest feature is that it can be completely biodegradable, but the cost is relatively high

Embodiment 1

[0029] Raw material ratio (parts by weight): clay: 100 parts; coal powder: 5 parts.

[0030] The production steps include:

[0031] (1). Crush the clay and pass it through a coarse sieve to remove stones therein;

[0032] (2). The above-mentioned proportioning clay and coal powder are mixed and placed in a ball mill, adding 210 parts by weight of water, and grinding for 3 hours;

[0033] (3). The obtained mud is pumped into the high-level mud pool;

[0034] (4). The above-mentioned mud flows into the low-level mud pool after passing through a 200-mesh sieve under the action of gravity;

[0035] (5). Use a pump to pump the mud in the low-level mud pool into the mud extractor;

[0036] (6). The mud squeezer with a 1.5kW output power motor maintains a pressure of 0.85MPa for 40 minutes to squeeze out most of the water in the mud, so that the water content of the mud is 25%;

[0037] (7). The above-mentioned mud material is placed in a vacuum mud refining machine, and the trac...

Embodiment 2

[0049] Raw material ratio (parts by weight): clay: 95 parts; coal powder: 10 parts; kaolin: 5 parts.

[0050] The production steps include:

[0051] (1). Crush the clay and pass it through a coarse sieve to remove stones therein;

[0052] (2). Mix the clay, coal powder and kaolin in the above ratio and place in a ball mill, add 165 parts by weight of water, and grind for 4 hours;

[0053] (3). The obtained mud is pumped into the high-level mud pool;

[0054] (4). The above-mentioned mud flows into the low-level mud pool after passing through a 250-mesh sieve under the action of gravity;

[0055] (5). Use a pump to pump the mud in the low-level mud pool into the mud extractor;

[0056](6). The mud squeezer with a 1.5kW output power motor maintains a pressure of 0.85MPa for 60 minutes to squeeze out most of the water in the mud, so that the water content of the mud is 20%;

[0057] (7). The above-mentioned mud material is placed in a vacuum mud refining machine, and the trac...

Abstract

The invention discloses a material composition of ceramic flying saucer target and preparing method, which consists of 80-120 clay and 2-10 coal powder. The preparing method comprises the following steps: (1) preparing paste according to certain rate of raw material and water through grinding; (2) sieving the paste; (3) removing most of water in the paste through mud-expelling machine; (4) pugging to prepare mould material through vacuum pugging machine; (5) placing certain quantity of mould in the flying saucer target mould; putting the mould on the chassis; rotating chassis and roller inversely through eccentric roller to roll the mould into flying saucer mould; (6) trimming the flying saucer target; demoulding; (7) sintering the flying saucer target mould in the high-temperature kiln; cooling to obtain ceramic flying saucer target.

Description

technical field [0001] The invention relates to a material composition of a flying saucer target and a manufacturing method thereof. Background technique [0002] UFO shooting, golf and tennis are known as the world's three noble sports. With the development of the world economy and the improvement of people's living standards, more and more people are throwing themselves into the entertainment and sports of flying saucer shooting. [0003] At present, the flying saucer target widely used in flying saucer shooting sports is made of asphalt as the main raw material. Because pitch contains aromatic hydrocarbons, various carcinogens represented by 3.4-benzopyrene, nitrogen-containing organic matter and oxygen-containing organic matter, etc., in the process of manufacturing and using flying saucer targets, it will cause certain harm to human health, and After this flying saucer target is shot and broken, a large amount of asphalt raw materials are scattered and remain in the s...
