Embodiment 1

[0047] The specific steps are as follows: a. After foaming the expandable polystyrene (EPS) by steam to form 2-3mm particles, put it into the slurry which is adjusted to a liquid state by adding sodium silicate and water at a weight ratio of 1:5.5, and then Put 28% of the liquid weight of kaolin into the slurry and fully stir it into a slurry; then put the 2-3mm particles of foamed polystyrene (EPS) into the slurry after stirring, and put it into the fluidized bed at 47 degrees Heated, dried and dried to become a modified polystyrene (EPS) metering standby;

[0048] b. Measure other solid fillers and fully stir them with the modified EPS particles for later use. The stirring time for the solid fillers is 11 minutes. The specific weight percentage of the solid fillers is:

[0049]

[0050] c. The preparation of the liquid slurry in the step is to use magnesium chloride:magnesium oxide (molar ratio) = 1:1.2, to prepare a magnesium chloride adhesive slurry and measure it, then...

Abstract

The invention relates to a fireproof heat-retaining plate for outer walls, and the fireproof heat-retaining plate is characterized by being formed by mixing a liquid adhesive paste and a solid filling material, wherein the weight percentage of the liquid adhesive paste is 70-90%, and the weight percentage of the solid filling material is 10-30%. The fireproof heat-retaining plate for outer walls disclosed by the invention is simple in manufacturing process, the fireproofing grade of the produced fireproof heat-retaining plate for outer walls reaches the grade A1, the coefficient of thermal conductivity is 0.065 W / (m.k), the compressive strength is greater than 1.5 MPa, and the apparent density is less than 210 kg / m<3>, so that the fireproof heat-retaining plate for outer walls completely reaches and is superior to the technical indexes of current other national inorganic heat-retaining materials.

Description

technical field [0001] The invention relates to the technical field of thermal insulation and fireproof materials for exterior walls, in particular to a fireproof and thermal insulation board for exterior walls and a production method thereof. Background technique [0002] Building energy conservation will be a key point in the development of China's construction industry in the 21st century. The current building energy consumption is huge, and the waste is seriously inconsistent with my country's current development goals. my country is a big energy-consuming country. The heating energy consumption per unit building area is about three times that of developed countries with similar climates. Building energy consumption has exceeded a quarter of the country's total energy consumption, ranking first in the country's energy consumption ratio. For this reason, the country has formulated the basic principle of "conserving energy and realizing sustainable development". [0003] ...
