Ceramic floor drain and preparation method thereof

Abstract

The invention discloses a ceramic floor drain and a preparation method thereof. The ceramic floor drain is prepared from, by mass, 8.0-12.0% of waste porcelain powder, 9.0-11.0% of potassium feldspar,7.0-9.0% of quartz, 1.5-2.5% of alumina, 2.6-3.2% of dolomite, 0.1-1.0% of a surfactant, 10.0-12.0% of paraffin and the balance kaolin. The ceramic floor drain has the advantages of low cost, high strength, high precision, great deformation resistance and the like.

Description

technical field [0001] The invention relates to a ceramic floor drain. Background technique [0002] At present, on the market, floor drains are mainly made of copper, plastic, alloy, stainless steel, etc., which have the following problems: [0003] 1. PVC material: [0004] 1. The material is brittle, easy to age, not durable, and has a short lifespan; [0005] 2. The compression resistance and wear resistance are not very good, and it is easily deformed by temperature; [0006] 3. The appearance is low-grade and looks cheap. [0007] 2. Stainless steel material: [0008] The materials used vary from good to bad, and it is difficult to guarantee uniform quality. Many manufacturers use 201 stainless steel to pretend to be 304 stainless steel, and even use 430 stainless steel, which is easy to rust. [0009] Three, all copper floor drain: [0010] Cast copper will also develop patina after a long time in a weakly alkaline environment (generally about 5 years). At the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The material is brittle, easy to age, not durable, and has a short lifespan;

[0005] 2. The compression resistance and wear resistance are not very good, and it is easily deformed by temperature;

[0012] 1. Relatively rough, not beautiful on the outside, and relatively cheap

[0013] 2. Poor corrosion resistance and short service life

Due to the main body of alumina, its price is high

[0017] There are also other ceramic floor drains with kaolin as the main component, but they have the following disadvantages: large deformation and low strength

The main reason is due to the characteristics of ceramic materials: (1) During the firing process of ceramic materials, there are more liquid phases, and under the action of gravity, ceramic materials are prone to the risk of bending deformation; (2) Ceramic materials Contains some moisture and organic matter. During the firing process, organic matter such as water volatilization and carbonates are heated and decomposed, resulting in shrinkage of the material (such as firing shrinkage), which in turn leads to deformation of the product; (3) When the ceramic clay is formed, Flaky clay particles are arranged in preferred orientation, so that the shrinkage perpendicular to the direction of clay flakes is large, while the shrinkage parallel to the direction of clay flakes is small

Causes deformation of the green body; (4) The ceramic material is brittle, so it is made into a thin product with low strength; (5) The precision of the ceramic product is low
