Novel green fireproof door core board and process for manufacturing same

Abstract

The invention discloses a novel green fireproof door core board. The novel green fireproof door core board is characterized in that the novel green fireproof door core board comprises a core board body and the thickness of the core board body is 2-5cm; a surface layer with the thickness being 0.5-1.5cm is respectively arranged on the upper surface of the core board body and the lower surface of the core board body and the core board body is a fireproof layer; the fireproof layer is made of cement, expansion particles, short filaments, bentonite, light calcium powder, melt glass, water, foaming agents and acrylic acid emulsion. As further improvement, the expansion particles are EPS foam particles. The novel green fireproof door core board is low in weight, easy to carry, convenient to cut and easy to construct, lowers building cost and is long in service life and especially, the load of the novel green fireproof door core board is lightened.

Description

technical field [0001] The invention belongs to a fireproof door for buildings and a production process of the fireproof door, and in particular relates to a novel green fireproof door core board and a preparation process thereof. Background technique [0002] At present, the development of society is inseparable from the construction industry. In modern society, people's requirements for the quality of the doors used are getting higher and higher. For a door, anti-theft and fire prevention are two important technical considerations, and they are also the difficulty and focus of door research and development. At present, fire doors are a very common door, and polystyrene foam boards, polyurethane foam boards, etc. are used as fire door core boards. These fire door core panels have excellent thermal insulation properties, light weight, and are easy to install, but they are all flammable materials and have poor fire resistance. At present, in order to ensure the fire preven...

AI Technical Summary

Problems solved by technology

In this way, first, the fireproof structure is treated separately, which increases the amount of construction and the cost of construction. The production process is complicated and the quality is increased, so it cannot be mass-produced in a factory

The second is that the core board of the fire door has been treated with fire protection, but it still does not meet the national A-level fire protection standard.
