Method for manufacturing novel wooden fireproof door leaf and door frame

Abstract

The invention discloses a method for manufacturing a novel wooden fireproof door leaf and a door frame. The door leaf consists of an integral skeleton 1 made of dry wood and a filling block 2 inside the skeleton; the door leaf filling block is filled in the integral skeleton 1 after waste wood is soaked into a novel fireproof coating 3; the novel fireproof coating 3 is sprayed on the surface of the door leaf, and the spraying thickness is 3 to 5 millimeters; during manufacturing, the door leaf of which the surface is sprayed with the novel fireproof coating 3 is put into a press and pressed for several hours, and then door leaf is normally solidified and shaped; the door frame consists of a transverse skeleton 4 and a longitudinal skeleton 5 made of dry wood; and a novel fireproof coating 6 is sprayed on the periphery of the door frame, and the spraying thickness is 3 to 5 millimeters. The door leaf and the door frame have the advantages of high-strength fireproof performance, excellent waterproof performance, greatly prolonged service life, fire resistance, waterproof property, high-temperature cracking resistance, deformation resistance, fireproof property, sound insulation and heat insulation. Compared with the prior art, the method has the characteristics of simple operation, convenient construction, low cost, quick response and the like.

Description

technical field [0001] The invention relates to a wooden fireproof door, in particular to a method for making a wooden fireproof door leaf and a door frame. Background technique [0002] The structure of the existing wooden fire doors generally uses fireproof rock wool and aluminum silicate wool as the filling inside the door. For the fir structure. The fire door of this structure can't play a fireproof effect at all, and there are deficiencies such as inflammability, poor fireproof performance, and short service life. [0003] In order to solve the fire prevention problem of wooden fireproof door leaves and door frames, Chinese patent CN2477797 announced a utility model patent for fireproof and water resistant door leaves and door frames that I applied for in 2001. Composed of flame-retardant fireproof boards, the door leaf frame and wooden skeleton are made of flame-retardant wood, and the space between the door leaf frame and wooden skeleton is filled with a barrier mad...

AI Technical Summary

Problems solved by technology

The fire-proof and water-resistant door leaf and door frame of this structure can play a certain fire-proof effect, and its fire-proof performance is greater than the 72 minutes of the national grade standard, but it still cannot play a real fire-proof effect.
