Description

One-step formed ceramic plate with preset shape on bottom surface

Technical Field

The utility model relates to a building pottery field, concretely relates to one shot forming's bottom surface contains predetermined figurative porcelain board.

Background

With the development of building technology and materials, ceramic products have gradually been widely used in various paving places due to their excellent physical and chemical properties and the ability of selectively copying a plurality of exquisite patterns by digital ink-jet. Ceramic tile products fired at high temperature in indoor decoration paving become common knowledge of consumers at the present stage, and in outdoor application, the traditional method mainly adopts stone, concrete, cement or brick and the like, along with the improvement of living standard and the increasing high-grade and secondary high-grade requirements of consumers and the improvement of ceramic product technology, the ceramic products are gradually popularized and developed as the bricks for being applied to places such as squares, districts, gardens and the like to realize more standard design and application, and the ceramic products are more attractive due to the advantages of industrialized mass production and the advantages in the aspects of physical and chemical properties, color number images and the like.

The ceramic product is mainly applied to paving the tiles for gardens or squares at the present stage by the following two methods:

one is a product with high water absorption rate, which has poor physical and chemical properties such as folding resistance, oxidation resistance, pollution resistance, color change and the like, is easy to break in use, has poor bearing property, high water absorption rate, is easy to influence by the environment, has increasingly poor surface color difference blocks, has poor appearance under the influence of weather such as daily rainwater and the like, and has poor unified image presentation in high-end requirement application.

Secondly, ceramic plate products with water absorption lower than 0.5% are adopted, and the products have good oxidation resistance and good physical and chemical properties compared with high-water-absorption products, are not easy to fade or have color difference problem, and can be used for a long time.

However, the bottom surface of the porcelain plate product in the prior art is in a concave-convex pattern shape with the depth not exceeding 2mm, and the product blank is almost in an integral flat plate type structure when viewed from the whole product body, and when the product blank is subjected to strong external pushing force such as the friction of wheels often passed by vehicles, the product blank and the concrete or sand or adhesive below the product blank are easy to displace beyond the stress range, and when the product blank is paved and attached, the bonding force between the product and the concrete below the product is easy to fade away, so that the product blank is easy to loosen; in addition, when the board similar to the flat-plate type shallow shading is paved and adhered on the ground and the wall surface, the specific surface area of the board adhered to the ground and the wall surface is small, the ground grabbing force and the adhesive force are not strong, and the board is just like steel plates paved and adhered to the steel plates due to low water absorption rate, and the board is in a strong-hard state, so that the transmission of force is not dispersed easily under external force, particularly impact force, the fracture phenomenon is easily generated, and a buffering toughness space is lacked; moreover, because the low water absorption product has high density, the plate which is similar to the plate with shallow concave-convex shading in the prior art is paved, and the condition of inconsistent shrinkage of the concrete below can be caused after a long time, so that the plate is easy to loosen.

In summary, the ceramic product in the present stage is limited in application to outdoor paving, such as squares, districts, gardens and other places, and there is a strong need for improving the safety, durability, firm adhesion and overall toughness of the ceramic product after being bonded with bonding materials such as cement after being paved, so as to expand the application range of the ceramic product in the field of outdoor paving.
