Problems solved by technology

[0003] 1. Although some thermal insulation materials have good thermal insulation effect, they have poor fireproof performance and cannot meet the requirements of Class A, so the scope of use is limited
[0004] 2. Although some insulation materials have good fire performance, they are either too bulky or too expensive, and their promotion and application are greatly restricted.
[0005] 3. Cement (or fly ash) polystyrene particle board, the bulk density is too heavy (more than 450 kg per cubic meter), the thermal conductivity is large, and the thermal insulation effect is not good. The use is limited to wall filling materials and external wall insulation

Embodiment 1

[0021] Raw material ratio: The ratio is based on the solid content of water glass glue. The solid content of water glass glue is 50%. Aluminum oxide accounts for 3% of the solid content of water glass glue, zinc oxide accounts for 5%, calcium carbonate accounts for 40%, fly ash accounts for 36%, magnesium oxide accounts for 20%, magnesium chloride accounts for 22%, starch accounts for 2%, waterproof agent ( Organosilicon waterproofing agent, produced by Jinan Guobang Chemical Co., Ltd.) accounted for 3%. The weight ratio of polyphenylene particles to water glass glue (based on its solid content, the same below) is 1:1.

[0022] Production process: Mix and stir the above-mentioned inorganic raw materials, then mix and stir with polystyrene particles, shape through the production line, microwave (or light wave, or high-temperature drying room) at 120°C-200°C, dry at high temperature, and demould, and you can get Inorganic modified polystyrene particle fireproof insulation boar...

[0024] Raw material ratio: The ratio is based on the solid content of water glass glue. The solid content of water glass glue is 40%. Aluminum oxide accounts for 6% of the solid content of water glass glue, zinc oxide accounts for 3%, calcium carbonate accounts for 30%, fly ash accounts for 30%, magnesium oxide accounts for 15%, magnesium chloride accounts for 25%, starch accounts for 3%, waterproofing agent ( Silicone waterproofing agent) accounted for 1.5%. The weight ratio of polyphenylene particles to water glass glue is 1:1.

[0025] Production process: Mix and stir the above-mentioned inorganic raw materials, then mix and stir with polystyrene particles, shape through the production line, microwave (or light wave, or high-temperature drying room) at 120°C-200°C, dry at high temperature, and demould, and you can get Inorganic modified polystyrene particle fireproof insulation board.

Embodiment 3

[0027] Raw material ratio: The ratio is based on the solid content of water glass glue. The solid content of water glass glue is 80%. Aluminum oxide accounts for 9% of the solid content of water glass glue, zinc oxide accounts for 7%, calcium carbonate accounts for 50%, fly ash accounts for 30%, magnesium oxide accounts for 15%, magnesium chloride accounts for 28%, starch accounts for 7%, waterproofing agent ( Stearic acid waterproofing agent, produced by Hunan Tongyun Building Materials Technology Co., Ltd.) accounted for 6%. The weight ratio of extruded particles to water glass glue is 1:1.

[0028] Production process: Mix and stir the above-mentioned inorganic raw materials, then mix and stir with polystyrene particles, shape through the production line, microwave (or light wave, or high-temperature drying room) at 120°C-200°C, dry at high temperature, and demould, and you can get Inorganic modified polystyrene particle fireproof insulation board.

Abstract

The invention discloses a mineral-modified organic heat-preserving grandules fireproof heated board, characterized in that the raw materials include water glass adhesive containing 40-5 percent of solid, alumina, zinc oxide, calcium oxide, calcium carbonate, fly ash, magnesia, magnesium chloride, starch, water repellent substance and polyphenyl granules or extruded granules or polyurethane granules. The fireproof performance of the fireproof heated board which is a noncombustible material can reach the national A-level demand for fireproof material. Because of light weight, good heat preservation effect and big coefficient of heat conductivity, the fireproof heated board can substitute rock wool, silicate cotton and glass wool, with energy-conserving and environment-protecting performances. The fireproof heated board realizes low cost and high benefit because a lot of waste polyphenyl granules can be recycled. The manufacture process needs no coal for combustion and discharges no three wastes,namely, waste gas, waste water and industrial residue, belonging to the clean manufacture process and saving water and energy.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an inorganic-modified organic heat-preservation particle fireproof heat-preservation board and a manufacturing process thereof. Background technique [0002] At present, the common insulation materials in the insulation material market at home and abroad include polystyrene foam board, extruded polystyrene board, polyurethane board, phenolic resin board, rock wool board, mineral wool board, glass wool board, aluminum silicate board, cement board, etc. (or fly ash) foam board, and cement (or fly ash) polystyrene particle board. The above heat insulating material has the following problems. [0003] 1. Although some thermal insulation materials have good thermal insulation effect, they have poor fireproof performance and cannot meet the requirements of Class A, so the scope of use is limited. [0004] 2. Although some insulation materials have good fire performance, ...
