preparation example Construction

[0016] A method for preparing a flame-retardant thermal insulation composite material. Firstly, polycrystalline mullite fibers of 100mm×50mm×20mm are spread on a clean glass plate, and then silicon dioxide-polyetheretherketone-triphenylphosphate The mixed solution is evenly dipped on the polycrystalline mullite fiber, and the above mixed solution is gently pushed with a glass rod to fully impregnate the ceramic fiber with the mixed solution, and then the silicon dioxide-polyether ether ketone-triphenyl phosphate is mixed The polycrystalline mullite fiber treated by solution impregnation is soaked in absolute ethanol solvent, and after 30-60s, it is taken out from the absolute ethanol solvent and the residual ethanol solvent is removed with a dry filter paper, and finally it is placed in an oven for drying. The drying temperature is 100-105°C, and after 10 hours, it is taken out from the oven and cooled to room temperature naturally to obtain the flame-retardant and thermal insu...

Embodiment 1

[0020] Pour 120g of N,N-dimethylacetamide solvent into a beaker, and heat the N,N-dimethylacetamide solvent to 80-90°C, then add 10g of polyether ether ketone, and stir it magnetically to make it Fully dissolve; after polyetheretherketone is completely dissolved, add 8g of triphenyl phosphate, stir the solution fully, then add 0.8g of polyvinylpyrrolidone to the above mixed solution, and stir the polyvinylpyrrolidone powder Dissolving, from the beginning of adding polyether ether ketone to the whole process of adding and completely dissolving polyvinylpyrrolidone, the temperature of the mixed solution is kept between 80 and 90°C; after the polyvinylpyrrolidone powder is completely dissolved, add 8g of polyvinylpyrrolidone to the mixed solution Silica powder, then cool the mixed solution to room temperature, and ultrasonically vibrate for 10 minutes to fully disperse the silica powder in the mixed solution to obtain a milky white slurry, which is silica-polyetheretherketone-trip...

Abstract

The invention discloses a preparation method of a fire-retardant and heat-insulation composite material. The method comprises the following steps: paving multi-crystal mullite fibers on a clean glass plate, then evenly coating a mixed solution of silicon dioxide-polyether-ether-ketone-triphenyl phosphate on the multi-crystal mullite fibers, lightly pushing the mixed solution with a glass stick to make the ceramic fibers be fully impregnated by the mixed solution, then soaking the multi-crystal mullite fibers, which have been processed by the mixed solution of silicon dioxide-polyether-ether-ketone-triphenyl phosphate, in an absolute ethanol solvent for 30 to 60 seconds, then taking out the fibers from the absolute ethanol solvent, removing the residual ethanol solvent with dry filter paper, finally drying the fibers in a baking oven, controlling the drying temperature of the baking oven in a range of 100 to 105 DEG C, after 10 hours taking the fibers out of the baking oven, and naturally cooling the fibers to the room temperature so as to obtain the fiber-retardant and heat-insulation composite material. The fire-retardant and heat-insulation composite material has the advantages of low price, high fireproof grade, damp absorption resistance, moisture and water absorption, small deformation coefficient, large toughness, chemical reagent corrosion resistance, stability, high temperature resistant performance, fireproof performance, and strong environment-friendliness.

Description

technical field [0001] The invention relates to a preparation method of a flame-retardant and thermal-insulation composite material, and more specifically, to a preparation method of a building flame-retardant thermal insulation material. Background technique [0002] With the continuous growth of my country's economy and the continuous advancement of urban-rural integration, the trend of large-scale, centralized, three-dimensional, specialized structures, and complex equipment has gradually formed. However, the development of corresponding domestic building insulation materials is relatively lagging behind. The existing materials cannot meet the market requirements, and the walls have high thermal conductivity, poor heat insulation performance, energy saving and fire resistance. [0003] It has become the top priority of the industry to vigorously develop new thermal insulation materials to meet the requirements of structural thermal insulation and energy saving, and strive...
