preparation example Construction

[0031] Such as figure 1 As shown, the method for preparing glass powder according to the embodiment of the present invention includes:

[0032] Step S1, weighing and mixing raw materials to obtain a mixture;

[0033] Step S2, melting the mixture to obtain a melt;

[0034] Step S3, cooling and grinding the melt to obtain glass powder;

[0035] Wherein, the raw material includes: SiO 2 30%-60%, BaO 10%-30%, Na 2 O 1%-5%, K 2 O 1%-10%, V 2 O 5 2%-10%, CaO 5%-10%, Al 2 O 3 1%-5%, B 2 O 3 0-5% and Fe 2 O 3 1%-3%. In the above method, SiO 2 And BaO are glass forming bodies, SiO 2 The content is between 30%-60%, if SiO 2 The content is less than 30%, it is not easy to form a glass state, if SiO 2 If the content is higher than 60%, the softening temperature of the glass body is too high, and it is not easy to fully infiltrate the metal during the high-temperature sealing process, causing the sealing failure. In addition, SiO 2 It also plays a role in improving the chemical stability of t...

Embodiment 1

[0050] Weigh the raw materials and mix them to obtain a mixture; melt the mixture at 1450°C for 15 hours to obtain a melt; quench the melt with water to form glass fragments, grind and sieve the glass fragments to obtain glass powder; wherein, Raw materials include: SiO 2 30%, BaO 30%, Na 2 O 5%, K 2 O 10%, V 2 O 5 10%, CaO 10%, Al 2 O 3 3%, B 2 O 3 0%, Fe 2 O 3 2% and modifier 0%.

Embodiment 2

[0052] Weigh the raw materials and mix to obtain a mixture; melt the mixture at 1600°C for 8 hours to obtain a melt;

[0053] The molten material is water-cooled, quenched and cooled to form glass cullet, and the glass cullet is ground and sieved to obtain glass powder; wherein the raw materials include: SiO 2 60%, BaO 10%, Na 2 O 1%, K 2 O 10%, V 2 O 5 6%, CaO 5%, Al 2 O 3 1%, B 2 O 3 2%, Fe 2 O 3 3% and modifier 2%, modifier includes SrO and MgO, and the weight ratio of SrO and MgO is 2:3.

Abstract

The embodiment of the invention provides a preparation method of glass powder, and the glass powder. The preparation method comprises the following steps: weighing raw materials, and mixing to obtaina mixture; melting the mixture to obtain a melt; and cooling and grinding the melt to obtain glass powder, wherein the raw materials comprise 30%-60% of SiO2, 10%-30% of BaO, 1%-5% of Na2O, 1%-10% ofK2O, 2%-10% of V2O5, 5%-10% of CaO, 1%-5% of Al2O3, 0-5% of B2O3 and 1%-3% of Fe2O3. The glass powder prepared through the method is high in TK-100 temperature, good in insulating property, capable ofmeeting the requirement for high-pressure resistance, good in water-resistant chemical stability and good in weather resistance, and can meet the performance requirement for glass and metal sealing materials with the requirement for high reliability, such as air conditioners, refrigerator compressor binding post products and the like.

Description

Technical field [0001] The invention relates to the technical field of glass, in particular to a method for preparing glass powder and glass powder. Background technique [0002] Existing glass used for iron and iron alloy sealing can meet general needs. For air conditioners, refrigerator compressor terminal products and other glass and metal sealing materials that require high reliability, it is difficult to meet the performance of related products. The temperature of TK-100 glass is too low, resulting in poor product insulation performance, high pressure resistance performance difficult to meet the demand, poor water resistance and chemical stability, can only reach the third level or lower standard, and weather resistance cannot meet the requirements. Summary of the invention [0003] In view of this, the present invention provides a method for preparing glass powder and glass powder to solve the problem that the temperature of traditional glass TK-100 is too low, resulting in ...
