Problems solved by technology

[0003] Ceramics can be used for building exterior walls to enhance the aesthetics of buildings. However, ceramics are easily corroded by rainwater during use, causing the surface to be oxidized or dirt to penetrate into the interior of the ceramics, resulting in yellowing of the ceramic surface or other impurities. The color will affect the appearance of ceramics. Moreover, due to the penetration of dirt into the interior of ceramics, it will also accelerate the aging of ceramics, resulting in the decrease of strength and cracking of ceramics after use.

Embodiment 1

[0032] A method for preparing ceramics with good weather resistance, comprising the following steps:

[0033] (1) Grind quartz stone and mica powder, pass through a 180-mesh sieve, mix with modified fly ash and bentonite, continue crushing, and pass through a 200-mesh sieve;

[0034] (2), mixing the mixture obtained in step (1) with diatomaceous earth, glass fiber, and nano-zinc oxide, ball milling, and passing through a 200-mesh sieve to obtain ceramic materials;

[0035] (3) Mix the ceramic materials obtained in step (2) with the mixed solution in a ratio of 10:1 by weight, disperse with a disperser, press and mold, and dry in the shade to obtain a green body; the mixed solution is polyethylene It is made by mixing alcohol and water at a weight ratio of 1:10;

[0036] (4) Heat the green body at 85-88°C and moisture content 85-90% for 36 hours, then raise the temperature to 595-605°C at 22-25°C / min, keep it warm for 30-45s, and heat it for 18-20 ℃ / min to raise the temperatu...

Abstract

The invention relates to a ceramic with good weatherability and a preparation method of the ceramic. The method includes the following steps: (1) preparing a ceramic material; (2) making the ceramic material into a blank body; (3) sintering. The ceramic prepared by the application method has better corrosion resistance and aging resistance effects, and the strength and wear resistance of the ceramic are further better.

Description

technical field [0001] The application belongs to the field of new building materials, and in particular relates to a ceramic with good weather resistance and a preparation method thereof. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. In the past, people called ceramics made of clay and fired at high temperature in special kilns. Ceramics is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. [0003] Ceramics can be used for building exterior walls to enhance the aesthetics of buildings. However, ceramics are easily corroded by rainwater during use, causing the surface to be o...
