Problems solved by technology

The integrated production is not flexible and convenient enough, and the production line occupies a large space
The entire production process has high requirements for operators, which is not conducive to the promotion and application of products and equipment
[0003] The core boards of fireproof boards in the prior art are mostly composed of calcium carbonate, polypropylene staple fiber, zinc molybdate and acrylic emulsion, and due to the limitation of their respective content ratios, the toughness and strength of the core board obtained by this scheme are poor, and cannot Harvest rolls
Moreover, the production process in the prior art adopts a constant temperature heating method, which makes the curing effect of the glue and the additives poor, so that the peel strength of the obtained core board is low

Abstract

The invention discloses a fireproof core coil and a manufacturing method thereof. The fireproof core coil comprises waterborne emulsion, inorganic flame retardant, inorganic filler, and enhanced aggregate; wherein the waterborne emulsion is selected from one or more of the combination of styrene-acrylic emulsion, styrene-butadiene emulsion, acrylic emulsion, acetic acrylic emulsion, and VAE emulsion; the inorganic flame retardant is selected from aluminium hydroxide, magnesium hydroxide or the combination thereof; the inorganic filler is selected from calcium carbonate, quartz sand or the combination thereof; and the enhanced aggregate is glass fiber. According to the fireproof core coil and the manufacturing method thereof, the composition and the manufacturing process of the conventional fireproof core coil are improved and optimized, the prepared core material has excellent flexibility and strength and can be folded to a coil-shaped structure at a low temperature, and the fireproof core coil is applicable to continuous production operation; and a wider modeling and design space is provided for machined finished product plates through the flexible core layer performance so that the application range of the product is greatly expanded.

Description

technical field [0001] The invention relates to the field of fireproof board core materials, in particular to an A2 grade fireproof core roll and a manufacturing method thereof. Background technique [0002] At present, there is no precedent of making A2 grade fireproof core layer into roll shape in the world and domestically. Existing technologies all directly make the core layer into A2 grade fire-proof metal composite panels, and the process of manufacturing the core layer is integrated with the process of manufacturing the composite panels. The manufacturing of the core roll is carried out separately from the two processes. The integrated production is not flexible and convenient enough, and the production line takes up a lot of space. The entire production process has high requirements for operators, which is not conducive to the popularization and application of products and equipment. [0003] The core boards of fireproof boards in the prior art are mostly composed...
