Embodiment 1

[0027] A high-strength fly ash-based fiber foaming self-insulation material, according to the weight ratio of raw materials: base material: fly ash 60%; plasticizer: organic polymer 0.05%; high-strength fiber 1.0%, gelling agent: 15% of cement; 20% of quicklime; 6% of gypsum. The plasticizer used is a high-molecular organic polymer, which can increase the cohesion between material particles, reduce the amount of cement, and enhance the bending resistance of the material And compressive strength, the used organic polymer can be waterborne epoxy resin, consumption is 0.05%; High-strength fiber can use polybenimidazole fiber, high-strength fiber can strengthen the flexural performance of material, increase the strength of material.

[0028] according to figure 1 The process flow chart for manufacturing the fly ash-based polymer foamed thermal insulation material shown, the high-strength fly ash-based fiber foamed self-insulated material, its preparation process includes the follo...

Embodiment 2

[0038] A high-strength fly ash-based fiber foaming self-insulation material, according to the weight ratio of raw materials: base material: fly ash 50%; plasticizer: phthalate diester 0.5%; glass fiber 0.5%; gelling Agent: cement 10%; quicklime 15%; gypsum 4%.

[0039] according to figure 1 The process flow chart for manufacturing the fly ash-based polymer foamed thermal insulation material shown, the high-strength fly ash-based fiber foamed self-insulated material, its preparation process includes the following steps:

[0040] (1) Raw material crushing: the raw material cement, quicklime, gypsum ball milled into 100 orders;

[0041](2) Slurry: Add the crushed raw materials into the mixer according to the weight ratio, and add fly ash, water and plasticizer, then fully stir, add water and stir to obtain a uniform slurry;

[0042] (3) Pouring: pour the slurry into the mold to foam, and the general mold is a cuboid;

[0043] (4) Plasticization: Transfer the mold containing th...

Embodiment 3

[0049] A high-strength fly ash-based fiber foaming self-insulation material, according to the weight ratio of raw materials: base material: fly ash 80%; plasticizer: bisphenol A epoxy resin 0.2%; polyester fiber 1.2%; Gelling agent: cement 8%; quicklime 12%; gypsum 8%, the bisphenol A type epoxy resin: epoxy group and hydroxyl endow the resin with reactivity, so that the cured resin has strong cohesion and adhesion ; The ether bond and hydroxyl group contained in the molecule are polar groups, which help to improve the wettability and adhesion; the ether bond and C-C bond contained in the molecule make the macromolecule flexible; the benzene ring contained in it endows the polymer with Heat resistance and rigidity; the isopropyl group reduces the intermolecular force, endows the resin with a certain degree of toughness, and increases the bending resistance of the material; due to the high bond energy of the -C-O- bond contained in the molecule, the alkali resistance is improved...

Abstract

The invention relates to the field of environment-friendly construction materials, and particularly relates to a high-strength fly ash based fiber foaming self-thermal-insulation material. The high-strength fly ash based fiber foaming self-thermal-insulation material comprises the following raw materials in percentage by weight: 30-90% of fly ash, 10-25% of lime, 3-10% of gypsum, 5-30% of cement, 0.01-3% of organic polymer and 0.05-3% of high-strength fiber. The block-shaped fly ash based polymer foaming thermal-insulation material is prepared through the following steps: performing ball milling on the raw materials to a certain particle size, proportionally mixing according to the weight percents, adding a proper amount of water, stirring to obtain uniform slurry, casting the slurry, foaming, forming, cutting, and drying. According to the invention, the solid waste fly ash is used as the main raw material; the preparation process is simple and low in energy consumption; the prepared light material has the characteristics of high strength, favorable mechanical property, durability, low ash drop possibility, light weight and the like; and the self-thermal-insulation material is a widely used environment-friendly construction material.

Description

technical field [0001] The invention relates to the field of environment-friendly building materials, in particular to a high-strength fly ash-based fiber foamed self-insulation material. Background technique [0002] With the development of industry, the consumption of coal increases accordingly. The burning of coal in large quantities has led to increasing environmental degradation. Therefore, the country has continuously increased its efforts to promote energy conservation and emission reduction, and the awareness of energy conservation and environmental protection has also continued to increase. With the burning of coal, a large amount of fly ash, an environmental pollutant, is also produced. Fly ash is a solid waste produced during the coal combustion process of power plant boilers, various industrial and civil boilers, and kilns. It enters the atmosphere with the discharge of flue gas. If it is not collected and properly treated, it will cause Waste of resources and ...
