Preparation method of wooden fireproof door and wooden fireproof door

Abstract

The invention relates to the technical field of fireproof doors, and discloses a wooden fireproof door. The wooden fireproof door comprises a door frame and a door leaf, a vertical frame and a horizontal frame of the door frame are both made of fast-growing wood flame-retardant laminated veneer lumber, a fireproof plate and a decorative clamping plate are sequentially pasted to the fire receivingsurface of the door frame, a groove is formed in the contact position of the inner side surface of the door frame and the periphery of the door leaf, fireproof expansion sealing strips are arranged inthe groove, and a plurality of door leaf frameworks are arranged in the door leaf. According to the preparation method of the wooden fireproof door and the wooden fireproof door, the flame-retardantlaminated veneer lumber fireproof door frame and the door leaf framework are manufactured by adopting the rotary cut veneers of the low-quality wood, so that the use value of the low-quality wood is improved, the dependence of the wood fireproof door on the high-quality wood is reduced, natural forest resources are protected, and the veneers are subjected to normal-pressure impregnation flame-retardant treatment; and when the fire receiving surface of the wooden fireproof door is subjected to flame and high temperature, the door frame and the door leaf are not prone to bending and deformation.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a method for preparing a wooden fire door and a wooden fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, it also has the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. [0003] The fire doors of the prior art are mainly lined with perlite to achieve fire prevention purposes. The overall structure of wooden fire doors is extremely simple and easy to manufacture. However, the planting area of ​​fast-growing wood in my country continues to expand, and the accumulation and harvesting of fast-growing wood are increasing year by year. However, due to some natural defects of fast-growing w...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a method for preparing a wooden fireproof door and a wooden fireproof door, which not only can replace solid wood to reduce the consumption of trees, but also reduce production costs, and at the same time have good flame retardant effects, etc. As well as improving the use value of low-quality fast-growing wood, the invention provides a preparation method for a wooden fireproof door and a wooden fireproof door, which solves some natural defects of fast-growing wood, such as low material, such as small diameter, low density, and easy Deformation, etc., making it difficult for fast-growing wood to directly meet the requirements of the frame and door frame of wooden fire doors
