Problems solved by technology

However, the EPS board or XPS board thin plaster external insulation system has been proved by a large number of engineering practices, and its integrity, durability, effectiveness, fire resistance, rainwater permeability, physical-chemical stability, etc. are insufficient, and the board The decoration effect is monotonous and single, and the decoration is poor, which cannot well meet people's requirements for the difference and uniqueness of decoration styles.
The traditional method is to add decorative panels outside the external insulation system, which greatly increases the construction cost

Abstract

The invention discloses a method for producing a heat insulating and preserving ceramic composite plate with decorative properties, comprising the following steps: preparing the powder of a decorative layer; preparing the powder of a heat insulating and preserving layer; loading the powder in a ceramic sagger in the secondary distribution way; sintering in a roller kiln in one time without drying and moulding by a ceramic pressing machine; demoulding, polishing and finishing the decorative surface, and determining the thickness and shape of the heat insulating and preserving surface by mechanical dry cutting. By the joint reaction of the ultrafine foaming agent, the dolomite, the diatomaceous earth and the polishing slag at high temperature, the heat insulating and preserving plate filled with tiny closed pores can be formed. The product has high strength, strong penetration resistance and lower thermal conductivity than the existing ceramic heat preserving material and has the characteristics of low production energy consumption, good decorative effect and prominent heat preservation, heat insulation and sound insulation effects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to ceramic composite plates with decoration and heat insulation effects. Background technique [0002] The total area of ​​various buildings in my country has reached more than 40 billion square meters, and building energy consumption accounts for about 27.5% of the total energy consumption in the country. Therefore, reducing building energy consumption is of great significance for us to achieve the goal of energy conservation and emission reduction. At present, the external wall thermal insulation technology systems promoted and applied by the Ministry of Housing and Urban-Rural Development mainly include polystyrene (hereinafter referred to as EPS) board thin plaster external thermal insulation system, extruded polystyrene (hereinafter referred to as XPS) board thin plaster external thermal insulation system 10 systems, rubber powder EPS granule thermal insulation slurr...
