Problems solved by technology

There are many pores on the surface and sides of polished vitrified tiles, which are easy to absorb dirt and have poor anti-fouling ability. At present, there is almost no polished vitrified tile in China that can really resist the pollution of tea or ink. Large-scale polished vitrified tiles generally have black hearts or Interlayer defects; Porous glass-ceramics is a decorative material that has only emerged in recent years. Its fatal disadvantages are many pores, easy deformation, many impurity spo

Embodiment 1

[0123] Decorative materials, the final product of which includes the percentage by weight of the net content of oxides: SiO 2 : 45%; R 2 O: 10%; RO: 40%; Al 2 o 3 : 5%; where R 2 R is an alkali metal element, and R is an alkaline earth metal element.

[0124] The preparation method of decorative materials is to measure the content of oxides in the raw materials, and then convert them in proportion, and select the ratio of raw materials according to the ratio of the weight percentage of the net content of oxides in the final product; crush the mixed raw materials into powder, and heat them at a temperature of 1100 ° C. Press down to obtain a billet with a density of 2.2 g / cm3; send the billet to a drying device for drying to obtain a dried material; send the dried material to a kiln for firing at a firing temperature of 1250°C. The sintering time is 100 hours, and the fired material is obtained; then the heating is stopped, and the temperature in the kiln naturally drops be...

Embodiment 2

[0126] Decorative materials, the final product of which includes the percentage by weight of the net content of oxides: SiO 2 : 65%; R 2 O: 20%; RO: 5%; Al 2 o 3 : 10%; where R 2 R is an alkali metal element, and R is an alkaline earth metal element.

[0127] The preparation method of decorative materials is to measure the content of oxides in the raw materials, and then convert them in proportion, and select the ratio of raw materials according to the ratio of the weight percentage of the net content of oxides in the final product; crush the mixed raw materials into powder, and heat them at a temperature of 1400 ° C. Press down to obtain a billet with a density of 2.4 g / cubic centimeter; send the billet to a drying device for drying to obtain a dried material; send the dried material to a kiln for firing at a firing temperature of 1400°C. The sintering time is 20 hours, and the fired material is obtained; then the heating is stopped, and the temperature in the kiln natura...

Embodiment 3

[0129] Decorative materials, the final product of which includes the percentage by weight of the net content of oxides: SiO 2 : 60%; R 2 O: 2%; RO: 38%; where R 2 R is an alkali metal element, and R is an alkaline earth metal element.

[0130]The preparation method of decorative materials is to measure the content of oxides in the raw materials, and then convert them in proportion, and select the ratio of raw materials according to the weight percentage of the net content of oxides in the final product; grind the mixed raw materials into powder, and heat them at 1300 ° C Pressing at high temperature to obtain a billet with a density of 2.5 g / cubic centimeter; sending the billet into a drying device for drying to obtain a dried material; sending the dried material into a kiln for firing, and the firing temperature is 1600°C. The firing time is 2 hours, and the fired material is obtained; then stop heating, and when the temperature in the kiln naturally drops below 600°C, the ...

Abstract

This invention relates to a kind of decoration material and its preparation method, which is attributed to the field of inorganic nonmetallic materials. Counting in terms of oxide net content, the terminal product comprises: 45~72% SiO2, 2~20% R2O, 5~40% RO and 0~10% Al2O3, where R2 represents alkali metals and R represents alkaline metals. It can also contains 0.0001~7% Fe2O3, 0~7% ZnO, 0~7% BaO, 0~7% TiO2, 0~8% ZrO2, 0~2% HfO2, 0~7% B2O3 and some fluoride. Thanks to reasonable composition and compact texture, properties such as modulus of rupture, compression strength after drying and Mohs' hardness of the decoration materials are better than those of granite and marble.

Description

technical field [0001] The invention relates to a decorative material and a preparation method thereof, belonging to the field of inorganic non-metallic materials. Background technique [0002] At present, the popular architectural decorative panels in the domestic and foreign markets mainly include granite, marble, ceramics, porous glass-ceramics, aluminum-plastic panels, and artificial marble. Granite has pores and cracks throughout the body, easy to absorb dirt, difficult to clean, uneven surface hardness, easy to wear, not durable surface gloss, easy to weather and deteriorate, large color difference, most of them have high radioactivity, great harm to the human body, and a large number of Mining will seriously damage the ecological environment, cause water and soil erosion, and endanger nature; marble structure is loose, low in strength, has cracks and a large number of pores, easy to absorb dirt, difficult to clean, low surface hardness, easy to wear, not suitable for ...
