Description

Heat-insulating high-temperature-resistant formaldehyde-free fireproof door core board

Technical Field

The utility model belongs to the technical field of the door core board and specifically relates to indicate a fire door core board is prevented to thermal-insulated high temperature resistant formaldehyde.

Background

Fire is one of the common disasters threatening the safety of human life. The fire door is a door having fire resistance, which gains time for people to escape from a fire when the fire breaks out, prevents the spread of the fire, delays the spread of the fire, and prevents high temperature. Therefore, the fire door plays an important role in the occurrence of a fire, and is widely applied to many fields such as residential buildings, ships, buildings, chemical engineering, mechanical engineering, and the like.

Although the fireproof door core plate material in the prior art can play the roles of fire prevention and heat insulation, the effect is slightly poor, and if the door burns, formaldehyde is generated, thereby causing the injury of human body.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model discloses to the disappearance that exists of prior art, its main objective provides a fire door core is prevented to thermal-insulated high temperature resistant formaldehyde, and it has effectively solved the thermal-insulated effect of preventing fires relatively poor and produce the injury problem that formaldehyde caused the human body.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a heat-insulating high-temperature-resistant formaldehyde-free fireproof door core board comprises an OSB substrate layer, wherein glass magnesium fireproof board layers are compounded on the upper surface and the lower surface of the OSB substrate layer; the outer surfaces of the two glass magnesium fireproof plate layers are both compounded with a high temperature resistant layer; the outer surfaces of the two high temperature resistant layers are both compounded with a wood decorative layer; the outer surfaces of the two wood decorative layers are coated with transparent paint-free layers; and the OSB substrate layer and the glass magnesium fireproof plate layer, the glass magnesium fireproof plate layer and the high temperature resistant layer and the wood decoration layer are bonded together through formaldehyde-free adhesives.

Preferably, the high temperature resistant layer is made of kraft paper material.

Preferably, the wood decorative layer is a formaldehyde-free wood material.

Preferably, the formaldehyde-free binder is a thermoplastic resin.

Preferably, the formaldehyde-free adhesive is water-resistant soy-based wood glue.

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:

by using the OSB substrate layer as a substrate, it is free from formaldehyde emission and is robust; the use of the glass magnesium fireproof plate layer and the high temperature resistant layer is matched, so that the utility model has the characteristics of heat insulation and high temperature resistance and is environment-friendly; the wood decoration layer is used for decoration, and the transparent paint-free layer is coated outside the wood decoration layer, so that the environment is protected, and the paint spraying process is avoided; meanwhile, the layers are bonded and fixed by formaldehyde-free adhesive, so that the environment is further protected.

To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
