Description

Technical Field

[0001] This invention belongs to the field of ceramic technology, specifically relating to a new material for paint-free porcelain slabs and a method for manufacturing porcelain slabs. Background Technology

[0002] As people's living standards improve, ceramic enthusiasts are no longer satisfied with buying ceramic products with exquisite patterns and bright colors, and are inclined to create their own ceramic works.

[0003] Chinese invention patent application document with application number 202510033271.5 discloses a new method for making porcelain paintings. The method is as follows: first, spray glaze on an ultra-thin white porcelain plate, then evenly sprinkle ceramic particles of different mesh sizes on the porcelain plate, and finally fire it at high temperature to form a new white porcelain plate that can be used for new porcelain paintings. High-temperature ceramic pigments are painted on the water-permeable texture of the surface of the new white porcelain plate, and then fired at a high temperature of 1280-1350℃ to form a new porcelain painting.

[0004] The aforementioned techniques require pre-spraying glaze onto the ceramic slab and firing it twice, which cannot meet the needs of ceramic enthusiasts who want to take their DIY ceramic creations home immediately after completion.

[0005] Chinese invention patent application No. 200810216169.5 discloses a method for producing high-temperature colored ceramic plate oil paintings, including the following steps: inputting color images into a computer; performing computer image processing and electronic color separation on the color images; outputting film using a laser imagesetter; exposing a screen printing plate; printing ceramic decal paper; transferring the ceramic decal paper to the ceramic plate; and high-temperature color baking.

[0006] Among the aforementioned technologies, image processing is relatively complex, and it also fails to meet the needs of ceramic enthusiasts who want to bring home their DIY ceramic creations immediately after completion.

[0007] Therefore, there is an urgent need for a type of porcelain slab material that allows the paint to dry easily after being painted on, without the need for firing in a kiln, so that ceramic enthusiasts can take it home directly. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new material for porcelain slabs that do not require firing for painting, as well as a method for making porcelain slabs. After painting on the porcelain slab, the pigments dry easily and do not need to be fired in a kiln. This is a porcelain slab material that ceramic enthusiasts can take home directly.

[0009] The present invention adopts the following technical solution: A new material for paint-free porcelain slabs comprises the following components by weight: 56.41-61.23 parts nano-quartz powder, 20.65-25.33 parts alumina, 0.42-0.51 parts iron oxide, 4.52-5.31 parts calcium oxide, 3.34-4.31 parts magnesium oxide, 1.98-2.75 parts potassium oxide, 0.44-0.62 parts sodium oxide, 10.12-13.61 parts yttrium oxide, 20.24-26.24 parts palygorskite, 0.32-0.41 parts quartz fiber, and 11.18-12.67 parts loss on ignition.

[0010] Furthermore, the new material for paint-free ceramic slabs comprises the following components by weight: 56.41 parts nano-quartz powder, 20.65 parts alumina, 0.42 parts iron oxide, 4.52 parts calcium oxide, 3.34 parts magnesium oxide, 1.98 parts potassium oxide, 0.44 parts sodium oxide, 10.12 parts yttrium oxide, 20.24 parts palygorskite, 0.32 parts quartz fiber, and 11.18 parts loss on ignition.

[0011] The method for producing porcelain slabs using the new paint-free porcelain slab material includes the following steps: S1. Material preparation: According to the stated mass fractions, the nano-quartz powder, alumina, iron oxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide and yttrium oxide are mixed, crushed and ground into powder to obtain abrasive material; S2, Modified According to the mass fraction, the palygorskite is crushed and ground into powder, and then heated to obtain modified palygorskite; S3, mixing ball mill, filter press The abrasive obtained in S1, the modified palygorskite obtained in S2, and the quartz fiber are mixed, and then water is added for ball milling to obtain a ball milling material. The obtained ball milling material is pressed and filtered into a plate shape in a mold to obtain a pre-fired ceramic plate. S4, Firing The pre-fired porcelain slab obtained in S3 is fired and cooled to obtain a porcelain slab that can be painted without firing.

[0012] Furthermore, the heating temperature in S2 is 400~450℃, and the heating time is 30~60min.

[0013] Furthermore, during ball milling as described in S3, the mass ratio of grinding media:water:balls is 1:1.2~1.3:1, the rotation speed of the ball mill is 500~650 r / min, and the milling time is 24~26 h.

[0014] Furthermore, the moisture content after pressure filtration described in S3 is 7-11%.

[0015] Furthermore, the firing curve described in S4 is as follows: Increase the temperature to 800-900℃ at a rate of 1.2-1.4℃ / min, and hold the temperature for 30-40 minutes; Increase the temperature to 1100-1200℃ at a rate of 0.9-1.0℃ / min and hold at that temperature for 3-4 hours. After natural cooling, a porcelain plate for painting without firing is obtained.

[0016] Compared with the prior art, the present invention has the following advantages: The new ceramic slab material of this invention produces a white ceramic slab after molding and firing. To improve the drying performance of the paint pigments, although alumina can also make the ceramic slab porous to absorb the paint pigments, it is far from sufficient to meet the needs. Therefore, modified palygorskite and quartz fiber are added to work in conjunction with alumina to increase the number of pores in the ceramic slab. The surface of the ceramic slab does not affect the painting effect. After the paint pigments dry, a permanent artwork can be formed with bright and transparent colors, allowing for unrestricted creation and meeting the painting needs of traditional Chinese painting and oil painting. It eliminates the need for firing, making it environmentally friendly and energy-saving.

[0017] To improve the aesthetics of the porcelain slab, yttrium oxide is added to enhance its whiteness. Attached Figure Description
