Embodiment 1

[0033] 15 parts of solid content is 50% EVA emulsion (comprising EVA and water in the EVA emulsion) and 30 parts of water, drop in the stainless steel container 2 that stirrer 1 is housed, stir, then 40 parts of hollow glass microspheres, 30 parts of magnesium hydroxide, 20 parts of sodium silicate and 2.5 parts of chopped glass fiber were put into the container 2 containing the EVA emulsion, and vigorously stirred to disperse the components evenly to form a paste 3 . Then spread the paste 3 evenly on the conveyor belt 4, send it into the infrared oven 5 for heating, and evaporate the water quickly, and the completely dried paste is compacted by the pressure roller 6 and the thickness of the product is controlled to form a sheet material 7, roll the rolled sheet 7 with a winder 8 to obtain a lightweight fireproof composite board core material, the preparation process is as follows figure 1 shown. Wherein, the bulk density of the hollow glass microspheres is 0.9g / cm 3 .

Embodiment 2

[0035] Put 12 parts of acrylic copolymer emulsion with a solid content of 50% and 80 parts of pulp with a concentration of 4% into a stainless steel container equipped with a stirrer and stir evenly, then add 55 parts of fly ash hollow microspheres, 10 parts of boric acid Add zinc, 15 parts of phosphate glass powder, 6 parts of aluminum hydroxide, and 4.8 parts of talc powder into the container, and stir vigorously to disperse the components evenly and obtain a paste. Spread the paste evenly on the conveyor belt, heat it in an infrared oven, and quickly evaporate the water. The completely dried paste is compacted by a pressure roller and the thickness of the product is controlled to form a sheet, and the roller is pressed well. The sheet material can be rolled to obtain a lightweight fireproof composite board core material. Wherein, the bulk density of the fly ash hollow microspheres is 0.2g / cm 3 .

Embodiment 3

[0037] Put 20 parts of polyurethane emulsion with a solid content of 50% and 30 parts of water into a container equipped with a stirrer, stir evenly, then mix 20 parts of hollow ceramic microspheres, 30 parts of low-temperature glass powder, 10 parts of perlite powder, 10 parts of 1 part of aluminum hydroxide, 3 parts of polyvinyl alcohol fiber, 5 parts of clay and 2 parts of silicon dioxide are put into a container, and vigorously stirred to disperse the components evenly and obtain a paste. Spread the paste evenly on the conveyor belt, heat it in an infrared oven, and quickly evaporate the water. The completely dried paste is compacted by a pressure roller and the thickness of the product is controlled to form a sheet, and the roller is pressed well. The sheet material can be rolled to obtain a lightweight fireproof composite board core material. Wherein, the bulk density of the hollow ceramic microspheres is 1.5g / cm 3 .

Abstract

The invention relates to a composite plate core, in particular to a lightweight class-A fireproof composite board core and a manufacturing method thereof. The lightweight class-A fireproof composite board core comprises, by weight, 3-10 parts of organic polymer, 10-80 parts of inorganic filler, 2-50 parts of ceramizing binder, 15-60 parts of hollow microsphere and 1-6 parts of fiber. The ceramizing binder can ceramize with the inorganic filler when a board is in a fire to form a ceramized material of certain strength; after the organic polymer is decomposed, the composite board core still has high strength, so that completeness of the composite board core is maintained, stripping, shedding and collapsing of the composite board core due to powdering of the composite board core are avoided, and safety is guaranteed.

Description

technical field [0001] The invention relates to a composite board core material, in particular to a lightweight A-grade fireproof composite board core material and a manufacturing method thereof. Background technique [0002] Due to the huge loss of personnel and property caused by fire, more and more attention has been paid to the flame retardancy of composite panel core materials. Especially in some public places, such as theaters, stations, subways, etc., the requirements for the flame retardant grade of composite board core materials are also getting higher and higher. In the event of a fire, since smoke is the main cause of casualties, these places require not only good flame retardancy, but also low smoke generation and heat release for the composite board core material. [0003] Inorganic flame retardants such as magnesium hydroxide, aluminum hydroxide, etc., can decompose and absorb heat when heated, and produce water vapor, and this type of flame retardant has good...
