A kind of silicon-ceramic sheet with adjustable water absorption and its preparation method

Abstract

The invention discloses a water absorption adjustable silicon porcelain sheet and a preparing method thereof and belongs to the field of building materials.The water absorption adjustable silicon porcelain sheet is composed of a base plate and a glaze decoration layer located on the base plate.The base plate is an inorganic material foaming layer.According to the raw material formula, the inorganic material foaming layer is prepared from 10-30 parts of feldspar, 15-40 parts of clay, 5-10 parts of quartz, 10-25 parts of kaolin, 5-15 parts of wollastonite, 8-15 parts of limestone and 1-5 parts of auxiliary tackifier; after high-temperature baking, the thickness of the silicon porcelain sheet ranges from 3 millimeters to 6 millimeters, and the water absorption ranges from 0.5% to 3%; the length to the width of a single silicon porcelain is 2 to 1 to 3 to 1, the length * width size of the single silicon porcelain is 2m*1m or 2.4m*1.2m or 3.6m*1.2m, and the area of the single silicon porcelain sheet is larger than or equal to 2 square meters.The silicon porcelain sheet is suitable for decoration of inner walls and outer walls of a building and can be widely applied to the field of manufacturing of large porcelain panels for buildings.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a decorative board for the inner and outer surfaces of buildings. Background technique [0002] Traditional building exterior wall decoration generally adopts the way of tile decoration. This architectural style is accepted by the public and has been widely used in exterior wall decoration. [0003] The date of the authorization announcement is April 26, 2006, and the Chinese invention patent with the authorization announcement number CN1253402C discloses an "ultra-thin fiber porcelain plate for interior and exterior wall decoration". Inorganic mineral fibers are mixed, and a composite surface layer including a bottom glaze layer and a top glaze layer is arranged on one side of the matrix layer; the ratio of length, width, and thickness of the porcelain plate is 3-1.5:2-1:0.008-0.003. [0004] In this technical scheme, inorganic mineral fibers are mixed in the clay of the base ...

AI Technical Summary

Problems solved by technology

[0005] However, the water absorption rate of the decorative porcelain plate made by this technical scheme is higher, usually 12 to 14%, which means that in a humid or rainy environment, the decorative porcelain plate per unit area (i.e. per square meter area) The weight of the board will increase by 13-15kg. If calculated according to the external area of ​​the entire building, it will be a weight that cannot be ignored. It will greatly increase the weight of the decorative porcelain board itself, which is not only harmful to the safety of the building, but also The strength requirements for the supporting structure are increased, so that it is subject to certain restrictions when used as decorative materials for the exterior walls of buildings, especially in the rainy and humid southern regions, if the water absorption rate of the materials for the interior and exterior walls of the building is high. , not only adversely affect the load bearing of the building, but also increase the construction cost and building cost, thereby increasing the one-time input cost of the owner, so the area of ​​use of the product is greatly restricted
