1. The cast iron, aluminum alloy and precise ceramics of the prior engine (an engine cylinder body and a cylinder cover) have the following difficulties: material cost and automobile cylinder processing cost are too high; aluminum alloys (engine cylinder and cylinder heads) cannot withstand higher temperatures and are easy to deform; (3) cast iron, aluminum alloy and precise ceramic cylinder body materials, the aluminum alloy has large integral mass under the same volume, and is not beneficial to reducing oil consumption; [ 4 ] oxidation reaction brought by the cast iron cylinder body material and the antifreeze solution has poor corrosion resistance and durability and is easy to rust; [ 5 ] aluminum alloy and precision ceramic cylinder materials, the strength is not high. (6) the melting temperature of the precision ceramic cylinder body material is too high, and the manufacturing process and the cost are too high. High-temperature glass with a softening point as high as 850 ℃ represented by the prior German Schottky company has melting and exhaust bubble temperature as high as 1650-; the difficulty and cost for researching and manufacturing the die-casting forming machine with the temperature as high as 1650-. The prior common glass can not meet the requirements of materials of engine cylinder bodies and cylinder covers in softening point and strength.
2. High temperature resistant building (high softening point fireproof glass) takes the product of German Schottky company as a representative, and the softening point is as high as 850 ℃. The product only contains 0-2% of calcium oxide or magnesium oxide and 3-5% of alumina, the temperature of [ melting and air bubble exhausting, homogenizing and clarifying ] of the glass is more than 1650-1680 ℃ when the viscosity logarithm (LogP) of the glass is 2.0, 1300-1600 ℃ of the glass of the invention is 50-380 ℃ lower; the embodiments of the invention are all at 1300 ℃ and 1460 ℃, and the embodiments of the invention are lower than 220 ℃ and 380 ℃. In the prior art, the manufacturing process is very difficult because the viscosity temperature is too high.
However, German Schottky corporation adopts the patent technology of bubble removal, homogenization and clarification by high-temperature vacuum pumping and platinum rod stirring to overcome the production difficulty. In the field of high-temperature resistant buildings (high-softening-point fireproof glass), the glass is the only technical enterprise capable of producing high-softening-point (850 ℃) level globally (with high qualification rate).

Detailed Description
The following examples of the present invention are described in detail (in this specification, unless otherwise specified, the contents of the various components in the glass are in weight percent).
In the embodiment of the invention, the softening point performance is measured by adopting ASTMC-338 standard.
In the embodiment of the invention, a rotational high-temperature viscometer of American THTA is adopted for measuring the viscosity.
The strength properties in the examples of the invention were measured in accordance with GB/T3810.4-2006.
The samples were measured by cutting them into small strips of 50mm by 5mm according to standard GB/T3810.4-2006. The strength described in our previous patents is generally determined without cutting the sample into small strips of 50mm x 5 mm. But because the cutting can cause pores and cracks or crazes on the glass strip, the strength data of the glass can generate large errors; only a comparison of the strength data of different glasses after the same cutting can be made. Except that the electronic touch screen glass has the standard of the devitrification strength, the devitrification strength is measured after chemical strengthening and physical polishing, and the conventional flat glass products have the standard of the devitrification strength which is only the standard of a measuring method.
Therefore, in the measuring process of the embodiment of the patent, a sample is cut into small strips of 50mm multiplied by 5mm, and then physical or chemical polishing is carried out, so that the defects of pores, cracks or cracks on the surface of the glass can be completely removed after cutting, the error of the real intensity data of the glass is small, and more accurate data can be obtained.

The cast iron, aluminum alloy and precise ceramics of the prior engine (an engine cylinder body and a cylinder cover) have the following difficulties: material cost and cost of automobile cylinder processing are too high; aluminum alloys (engine cylinder and cylinder cover) cannot withstand higher temperatures and are easy to deform; (3) cast iron, aluminum alloy and precise ceramic cylinder body materials, the aluminum alloy has large integral mass under the same volume, and is not beneficial to reducing oil consumption; [ 4 ] oxidation reaction brought by the cast iron cylinder body material and the antifreeze solution has poor corrosion resistance and durability and is easy to rust; [ 5 ] aluminum alloy and precision ceramic cylinder materials, the strength is not high. (6) the melting temperature of the precision ceramic cylinder body material is too high, and the manufacturing process and the cost are too high. High-temperature glass with a softening point as high as 850 ℃ represented by the prior German Schottky company has melting and exhaust bubble temperature as high as 1650-; the difficulty and cost for researching and manufacturing the die-casting forming machine with the temperature as high as 1650-. The prior common glass can not meet the requirements of materials of engine cylinder bodies and cylinder covers in softening point and strength.
2. High temperature resistant building (high softening point fireproof glass) takes the product of German Schottky company as a representative, and the softening point is as high as 850 ℃. The product only contains 0-2% of calcium oxide or magnesium oxide and 3-5% of alumina, the temperature of [ melting and air bubble exhausting, homogenizing and clarifying ] of the glass is more than 1650-1680 ℃ when the viscosity logarithm (LogP) of the glass is 2.0, 1300-1600 ℃ of the glass of the invention is 50-380 ℃ lower; the embodiments of the invention are all at 1300 ℃ and 1460 ℃, and the embodiments of the invention are lower than 220 ℃ and 380 ℃. In the prior art, the manufacturing process is difficult because the viscosity temperature is too high.
But German Schottky company adopts the patent technologies of high-temperature vacuumizing and platinum rod stirring for bubble removal, homogenization and clarification to overcome the production difficulty. In the field of high-temperature resistant buildings (high-softening-point fireproof glass), the glass is the only technical enterprise capable of producing high-softening-point (850 ℃) level globally (with high qualification rate).
3. In the daily and industrial glassware and fields of high temperature resistance (such as glass pots, glass tubes, micro-glass furnace plates, kitchen range plates) and the like in the prior art: the product of Corning company in America is taken as a representative, the manufacturing process of the product is very difficult, the product only contains 0-2% of calcium oxide or magnesium oxide and 3-5% of alumina, and the temperature of [ melting and air bubble exhausting, homogenizing and clarifying ] of the glass is more than 1630 and 1640 ℃ when the viscosity logarithm (LogP) of the glass is 2.0.

The prior art has difficulty in manufacturing the adhesive because the viscosity temperature is too high.
The United states Corning company adopts the patent technology of bubble removal, homogenization and clarification of a platinum channel to overcome the production difficulty. In the fields of high-temperature resistant glassware and the like in daily use and industry (such as glass pots, glass tubes, micro-glass furnace plates, kitchen range plates), and the like, the glass is a globally important (high-qualification-rate-capable) technical enterprise with the level of producing high softening point (770 plus 820 ℃).
4. In addition, when the above [ patent technologies for high-temperature vacuum pumping and platinum bar stirring for bubble discharging, homogenization and clarification ] and [ patent technologies for bubble discharging, homogenization and clarification of a platinum channel ] are not adopted by enterprises in various countries, the softening point is [ 1 ] or is difficult to reach (770-: 【2】 Or the raw materials are not fully melted because the viscosity temperature is too high in the production (serious defects of slag points occur), and the product is unqualified. 【3】 Or the product is unqualified because the viscosity temperature is too high (bubbles cannot be fully removed) in the production process, and serious defects are generated. 【4】 Or the viscosity temperature is too high in production, so that serious defects (unqualified glass ribs) are generated in the forming process stage, and the formed product is unqualified.
The differences between the prior art and the present invention
The invention relates to an application of a glass composition with a high softening point, belonging to the field of high-temperature resistant glassware and high-temperature resistant glass fibers such as engine cylinder body and cylinder cover glass, high-temperature resistant explosion-proof glass, building fireproof glass, daily and industrial glass (such as glass pots, glass tubes, micro glass furnace plates, kitchen range plates) and the like in the prior art.
The invention is disclosed [ in weight percent, the content of alumina in the glass is 1-38.5%, the content of magnesia is 4-23%; the content of silicon oxide is 1.6-9.5 times of the content of calcium oxide, and the content of calcium oxide is 0.6-2.5 times of the content of magnesium oxide. Comprising: (1) the softening reaches the properties of the new advanced glass material of 770 ℃, [ 820 ℃ ] & 1080 ℃ ], or [ 850 ℃. & 1080 ]. (2) And the temperature of melting, bubble discharging, homogenizing and clarifying when the viscosity logarithm value (LogP) of the glass is 2.0 is 1280-1600 ℃. Or 1300 ℃ to 1520 ℃. Or the unique eutectic body of silicon, calcium, magnesium and aluminum in the new advanced glass material at 1300-1430 ℃.
The invention also provides a technical scheme with different technical concepts, and the technical effect of the invention can basically reach the prior top technical level; and can also greatly exceed the state of the art at the top level.
The invention also relates to a use invention of chemical products, which is invented based on the discovery of new properties of the products and the utilization of the properties. Whether new or known, the properties are inherent in the product itself, and the essence of the invention lies not in the product itself, but in the application of the properties of the product.
The invention comprises the following steps:
1. the invention is advanced material glass, which can overcome the problems of the prior cast iron, aluminum alloy and precise ceramics
The technical difficulties of the engine cylinder body and the cylinder cover are as follows: the advanced material glass is used for engine cylinder bodies and cylinder covers, and is lighter than cast iron by more than 3 times and lighter than aluminum alloy when the volume of the glass is equal, so that the glass material has small integral mass and the cylinder bodies have the advantages that: A. the generated heat load capacity is stronger, B. can bear larger horsepower, C. is favorable for reducing oil consumption and the like, and has 3 technical effects which cannot be expected. The strength of the advanced material glass used for engine cylinder bodies and cylinder covers can reach 380MPa which is about 50 percent higher than the 250-strength of aluminum alloy 150; 20-50% lower than that of cast iron 250-500 MPa, but if the volume is increased by 20%, the strength of the cast iron can be achieved, and the cast iron is 2 times lighter than that of the cast iron, so that the engine cylinder body and the cylinder cover have the advantages of wear resistance, durability and capability of bearing large horsepower. The cost of the advanced material glass used for the engine cylinder body and the cylinder cover is about 2500 yuan per ton, which is 7 times lower than that of the aluminum alloy 18000 yuan per ton; compared with 3500 Yuan-ren-Min-Bi-ton cast iron engine cylinder and cylinder cover, the cost is 40% lower, so that the economic bottleneck that the cost is too high and the application range is small due to the aluminum alloy (aluminum alloy) can be overcome.
Therefore, the advanced material glass is used for engine cylinder bodies and cylinder covers, and has the following advantages compared with cast iron and aluminum alloy: the lighter A. generates stronger heat load capacity, B. can bear larger horsepower, C. is favorable for reducing oil consumption and other 3 technical effects which cannot be expected. Can simultaneously have the following functions: due to its higher strength [ engine block and cylinder head ], the technical effect of being unsuited for wear resistance and durability and being more able to withstand large horsepower. Can simultaneously have the following functions: the characteristics of 7 times lower cost than cast iron and aluminum alloy can be used, and the technical effect that the material cannot be fed is achieved, and the material is lighter than aluminum alloy (engine cylinder body and cylinder cover).
High-temperature glass with a softening point as high as 850 ℃ represented by the prior German Schottky company, a melting temperature as high as 1620 ℃ and 1680 ℃, and the engine cylinder body and the cylinder cover cannot be produced on a mature die-casting forming machine at about 1400 ℃; the difficulty and cost for researching and manufacturing the die-casting forming machine with the temperature as high as 1620-. The melting temperature of the glass can reach 1300-1400 ℃, and the glass can be produced on a mature die-casting forming machine (an engine cylinder body and a cylinder cover) at about 1300-1400 ℃, and has the technical effect of no material supply. And [ 5 ] in the limit temperature resistance and deformation points of the engine cylinder body and the cylinder cover, because the change value of the thermal expansion of the aluminum alloy material and the cast iron is very large when the temperature rises by 100 ℃, the deformation degree is also very large, in the limit temperature resistance and deformation points of the engine cylinder body and the cylinder cover, the aluminum alloy material is about 350 ℃, and the cast iron is 450 ℃. The softening point of the glass can reach 850-1080 ℃, and the deformation point can also reach 700-900 ℃. And because the change value of the thermal expansion of the glass of the invention is very small (within 2-4 ppm) when the temperature rises by 100 ℃, and the deformation degree is very small, the glass of the invention can resist the extreme temperature of an engine cylinder body and a cylinder cover and can also reach 700-900 ℃. This helps [ engine block and cylinder head ] withstand higher temperatures without modification. Can also help to overcome the problem that the glass material has inferior thermal conductivity to cast iron and aluminum alloy, and has the technical effect of being not pre-dosed. And [ 6 ] because the glass material of the invention has lower viscosity but higher softening point, when the cylinder body of the engine is produced by adopting the pressing or casting or die-casting forming process, the cost is lower than that of cast iron, aluminum alloy and precise ceramic, the qualification rate is higher, and the invention has the technical effect of europium which cannot be pre-dosed. [ 7 ] the existing traditional glass has low softening point, and is not suitable for being made into a cylinder body and a cylinder cover of an engine, which can bear higher temperature and is not easy to deform. Aluminum alloys (engine cylinder and cylinder cover) are made of materials, oxidation reaction brought by antifreeze is poor in corrosion resistance and durability, and oxidation reaction brought by iron castings (engine cylinder and cylinder cover) is poor in corrosion resistance and durability and easy to rust; as known to persons skilled in the art, the glass material of the invention has the characteristics of overcoming the difficulties of oxidation reaction, poor corrosion resistance and durability and easy rusting caused by cast iron and aluminum alloy cylinder body materials and antifreeze, and having the technical effect of no material supply. Glass is inferior to cast iron and aluminum alloys in thermal conductivity, but this problem can be solved by improvements in cooling water systems [ engine block and cylinder head ]. Cast iron and aluminum alloys [ engine cylinder and cylinder head ], are inferior to the glass material of the present invention in hardness, so the present invention [ engine cylinder and cylinder head ] is more advantageous in wear resistance and durability and has technical effects that the materials cannot be expected. Precision ceramic materials, as known to those skilled in the art, are usually manufactured by high-temperature ceramic powder solid vacuum pumping and high-pressure process, and have extremely high manufacturing process and cost, and are used as large-scale automobiles (engine cylinders and cylinder covers). The glass material of the invention adopts a liquid glass die-casting manufacturing process, so the cost is many times lower, and the glass material has the technical effect that the material cannot be pre-fed.
2. The present invention can produce a softening point (770-. (1) The invention achieves the properties of a new advanced glass material with a softening point of 771-; (2) also produced levels at log p of 2.0 over [ top prior art schottky company germany and corning company usa ], resulting in lower advanced [ melting and debubbling, homogenizing, clarifying ] temperatures of 1280 ℃ to 1600 ℃; or 1300 ℃ to 1520 ℃; or the unique eutectic body of silicon, calcium, magnesium and aluminum in the new advanced glass material at 1300-1430 ℃.
Compared with the glass of German Schottky corporation of 1650-; the embodiments of the invention are all at 1300 ℃ and 1460 ℃, and the embodiments of the invention are lower than 220 ℃ and 380 ℃.
Therefore, the invention can overcome the defects of the prior art in the high-temperature resistant and explosion-proof glass, the fire-proof glass for buildings, the high-temperature resistant glassware for daily use and industry (such as glass pots, glass tubes, micro glass furnace plates, kitchen range plates) and the like and the high-temperature resistant glass fiber industry:
technical bottlenecks and difficulties of high viscosity temperature [ melting and degassing bubbles, homogenization, clarification ] at a log p of 2.0: can not adopt the high-temperature vacuumizing and platinum-holding stirring exhaust bubble patent of German Schottky company, can also overcome the production difficulty, becomes an enterprise with higher global qualification rate, and produces the softening point level of 771-. Therefore, the invention is also a change invention of the technical essentials.
The invention therefore provides a technical solution with a different technical concept, the technical result of which can substantially reach the state of the art. Can reach the softening point at 770-820-850 ℃ in production; can also reach the higher technical level of softening point [ 851-. And the technical effect of building fire prevention which cannot be expected is generated:
3. the invention can: (1) overcoming the prior art in production (in order to reach [ 770-
High softening point and a viscosity (LogP) of 2.0 [ technical bottleneck and difficulty of too high viscosity temperature of melting and degassing bubbles, homogenization, clarification ]). The method overcomes the serious defect that the raw material is not fully dissolved because the viscosity temperature is too high in the prior art and slag points are not fully dissolved, thereby forming the difficulty of product unqualified. (2) Overcome the technical bottleneck and difficulty of the prior art (too high viscosity temperature of [ melting and degassing bubble, homogenization, clarification ] at a viscosity (LogP) of 2.0 in order to reach a high softening point of [ 770-. The problem that the product is unqualified due to serious defects caused by too high viscosity temperature (bubbles are not fully eliminated) in the prior art is overcome. (3) Overcome the technical bottleneck and difficulty of the prior art in production (too high viscosity temperature of melting and degassing bubble, homogenization and clarification) when the viscosity (LogP) is 2.0 in order to reach the high softening point of 770-850 ℃). (4) The difficulty that the serious defect of the prior art in the molding process stage (generating unqualified glass beads) is overcome because the viscosity temperature is too high.
The technical effect that the product percent of pass can be greatly improved is produced.
4. The invention can achieve higher softening temperature (851-
The technical effect that the building fire prevention of fire prevention and explosion prevention can not be supplied (bearing more flame barbecue time and greatly increasing the fire prevention and explosion prevention) can be generated by pointing at the technical level (see the embodiment)
5. The temperature of [ melting and air bubble discharging, homogenizing and clarifying ] is 1280-1640 ℃ when the log P is 2.0; 1300 ℃ to 1520 ℃; the unique eutectic body of silicon, calcium, magnesium and aluminum in the new advanced glass material at 1300-1430 ℃. Compared with the prior world top grade CN technology, Germany Schottky company and American Corning company, the temperature is lower by 100-. Because the temperature of the melt viscosity is lower than 120-300 ℃ in the prior art, and the energy consumption is mainly in a high-temperature area, the technical effect that the materials cannot be fed (the energy consumption can be saved by 30-40 percent, and the carbon dioxide emission can be reduced by 30-40 percent) is generated.
6. Due to the existing world top grade, CN technology German Schottky company and American Corning company, products in high-temperature resistant glassware and fields such as high-temperature resistant high-softening point glass, fireproof and explosion-proof glass and prior daily and industrial glass and industry types (such as glass pots, glass tubes, micro glass furnace plates, kitchen burning range plates) and the like have high viscosity, only 3-6% of alumina is contained, otherwise the viscosity is higher and more difficult to produce. The viscosity temperature of [ melting and degassing bubble, homogenization, clarification ] at a log p of 2.0 is 1280 ℃ to 1640 ℃; 1300 ℃ to 1520 ℃; the unique eutectic body of silicon, calcium, magnesium and aluminum in the new advanced glass material at 1300-1430 ℃. The viscosity temperature is 100-380 ℃ lower than that of the prior art [ melting and air bubble discharging, homogenizing and clarifying ], and the strength can be 2-3 times higher than that of German Schottky company and American Corning company because the [ invention ] can contain 20-35% of alumina (see the examples in the specification). Therefore, when the glass is roasted at 850 ℃ according to the standards of high-temperature glass and fireproof glass, the technical effects that the glass can bear large stress change due to higher strength, bear longer roasting time of flame and greatly improve the fireproof and explosion-proof capability cannot be achieved are achieved.
7. At present, in all knowledge and at education books and known technologies: 1. the invention is not concerned with the invention [ in weight percent, the content of alumina in the glass is 1-38.5%, the content of magnesia is 4-23%; in the technical scheme that the content of the silicon oxide is 1.6-6.2 times of the content of the calcium oxide, and the content of the calcium oxide is 0.6-2.5 times of the content of the magnesium oxide, the disclosed softening reaches the expression of the properties and the low-viscosity temperature properties of the novel advanced glass material [ 770-820-850-1080 ℃.
8. At present, in all knowledge and at education books and known technologies: none of the above has been generated: 【A】 The invention overcomes the major technical difficulties of the industry in the world, and has the technical effects that the product qualification rate is greatly improved and the materials cannot be supplied; 【B】 The invention can also reach the higher softening point technical level of 851-; 【4】 The invention has the technical effect that the materials cannot be supplied because the high-strength performance can bear more flame roasting time and greatly improve the fireproof and explosion-proof effects.
The invention also provides a technical scheme with different technical concepts, the technical effect of the invention can basically reach the prior art, and the application of the known product can be considered as inventive. The present invention is therefore a significant advance.
The invention also discloses the application of the chemical product, which is invented based on the discovery of new properties of the product and the utilization of the properties, and the invention of the application of the known product can be considered as inventive.
