Preparation method of waterproof granite-imitated plate

Abstract

The invention belongs to the field of granite-imitated plates, and particularly relates to a preparation method of a waterproof granite-imitated plate. The preparation method comprises the following steps: stacking and distributing a backing material and a surface material, and performing pressing andporcelainization sintering to prepare a compact waterproof structure; herein, the surface materialis mainly prepared from the following raw materials in parts by weight: 30-60 parts of potassium-sodium feldspar particles, 40-50 parts of potassium-sodium feldspar powder, 15-18 parts of a binder, 15-18 parts of a flux and 0-5 parts of a pigment; the backing material is mainly prepared from the following raw materials in parts by weight: 50-80 parts of waste ceramic tile particles, 20-50 parts of waste ceramic tile powder, 13-15 parts of a binder and 5-8 parts of a flux; wherein the particle size of the waste ceramic tile particles is 10-25 meshes, and the particle size of the waste ceramictile powder is 25-100 meshes. The artificial granite plate prepared by the method is good in decorativeness, the breaking strength reaches 10-30 MPa, and the artificial granite plate is not prone to dirt absorption and dirt storage, easy to clean and high in antifouling capacity.

Description

technical field [0001] The invention belongs to the field of imitation granite plates, and in particular relates to a preparation method of an impermeable imitation granite plate. Background technique [0002] With the continuous development of my country's urbanization process, the area of ​​outdoor municipal squares, greenways, public gardens and other places is increasing, and the requirements for floor tiles in these places are also getting higher and higher. For example, in some occasions, in addition to good decorative effect, floor tiles are required to have better anti-fouling properties to facilitate cleaning and cleaning with water to ensure a continuous aesthetic feeling; floor tiles are also required to have high The carrying capacity to meet the requirements of vehicle traffic. [0003] At present, in some occasions, the floor tiles used in the above places are permeable bricks. Although the permeable bricks can also be made into imitation granite varieties, wh...

AI Technical Summary

Problems solved by technology

[0003] At present, in some occasions, the floor tiles used in the above-mentioned places are permeable bricks. Although the permeable bricks can also be made into imitation granite varieties, which have good decorative properties, the anti-fouling ability of the permeable bricks is not high, and it is not easy to clean. unsatisfactory

Moreover, the flexural strength of permeable bricks is only 4.5-6.0MPa, which cannot meet the traffic capacity of vehicles, especially heavy vehicles. It will be found that the ground bricks will be broken due to repeated traffic of vehicles, which will also affect the aesthetics of public places. and practical experience
