Embodiment 1

[0022] The raw materials are reinforced with 65% of marble waste, 10% of perlite waste, 15% of zeolite waste, 2% of phosphate slag, 5% of clay waste, 0.5% of starch, 1% of iron oxide, 1% of sodium tripolyphosphate, and ceramic body. After 12 hours of dry ball milling in a ball mill, pass through a 225-mesh sieve and dry press at 35 MPa to obtain a 30mm thick adobe, and reduce the moisture content of the adobe to 7% in the drying room, and then Send it into the roller kiln, burn it at the highest temperature of 950°C for 100 minutes, and then cool it naturally.

Embodiment 2

[0024] The raw materials are 61.4% of quartz feldspar stone waste, 15% of perlite waste, 10% of zeolite waste, 1% of phosphate slag, 9% of clay waste, 0.1% of polyethylene glycol (PEG4000), 3% of iron oxide, lemon Sodium acid 0.2% and ceramic body reinforcing agent 0.3% by mass are dry-milled in a ball mill for 10 hours, passed through a 250-mesh sieve, and then dry-pressed at 35MPa to obtain a 60mm-thick brick. The moisture content of the product is reduced to 5%, and then sent to the roller kiln for 80 minutes at the highest temperature of 980 ° C, and then naturally cooled.

Embodiment 3

[0026] The raw materials are 50% of granite waste, 16% of perlite waste, 18% of zeolite waste, 3% of phosphate slag, 10% of clay waste, 0.3% of urea, 1.5% of iron oxide, 0.8% of sodium lignosulfonate, ceramic body The mass ratio of 0.4% of the reinforcing agent is dry-milled in the ball mill for 11 hours, passed through a 200-mesh sieve, and then dry-pressed at 35MPa to obtain a 45mm thick brick, and the moisture content of the brick is reduced to 6% in the drying room. It is then sent to a roller kiln for 90 minutes at a maximum temperature of 1110°C and then cooled naturally.

[0027] Among the above raw materials, perlite waste comes from Qingshan Township, Luoshan County, Henan Province; zeolite waste comes from Zhubian Town, Junan County, Shandong Province; phosphorite slag comes from Yangdun Town, Songxi County, Fujian Province; clay waste comes from Luwu Town, Lingshan County, Guangdong Province , The granite waste comes from Shuitou Town, Nan'an City, Fujian Province, ...

Abstract

The invention discloses an environment-friendly thermal-insulation decorative foamed ceramic plate. Raw materials comprising, by mass, 50%-65% of stone waste, 10%-16% of perlite waste, 10%-18% of zeolite waste, 1%-3% of phosphate slag, 5%-10% of argil waste, 0.1%-0.5% of a foaming agent, 1%-3% of ferric oxide, 0.2%-1% of a grinding aid and 0.3%-0.5% of a ceramic green body reinforcing agent are mixed and ground, then sequentially subjected to dry-pressing molding and drying, fired at the temperature of 950-1110 DEG C for 80-100 min after drying, and naturally cooled to obtain the product. Thefoaming degree is high, most of foaming holes are closed holes, and good thermal preservation and thermal insulation effects are achieved; meanwhile, high bending strength, low radiativity and high flame retardancy are guaranteed, the firing temperature is low, the time is short, the production energy consumption is low, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environment-friendly thermal insulation decorative foamed ceramic plate and a preparation method thereof. Background technique [0002] Wall insulation material is a new type of wall insulation material developed in recent years. Foamed ceramics have high porosity, low thermal conductivity, light weight, high hardness, thermal shock resistance, high temperature resistance, corrosion resistance and good mechanical strength. Excellent performance, can be used as an ideal building thermal insulation material. Foamed ceramic board has the characteristics of light weight, good waterproof, fire retardant, small deformation coefficient, anti-aging, stable performance, etc. It has good compatibility with wall base and plastering layer, good safety and stability, and can overcome the fear of organic materials. Achilles heel of open flame and easy aging. However, most of the existing...
