Solid wood fire door manufacturing method and solid wood fire door

Abstract

The present invention relates to the technical field of fire doors, in particular to a method for making a solid wood fire door, which comprises the following steps: S1. wood cutting to form an embryo body; S2. drying the embryo body; S3. immersing the embryo body in a pretreatment solution for 30 minutes ~40min; S4. Take out the embryo body and spray frozen gas toward the embryo body to cool the embryo body to below 0°C; S5. Thaw the embryo body at room temperature; S6. Cut and polish the thawed embryo body to form a solid wood fire door; The treatment liquid includes the following components in parts by mass: 100 parts of water; 15 to 30 parts of wood flame retardant; 1.2 to 1.5 parts of telluric acid; 0.01 to 0.03 parts of tellurium dioxide; 1.1 to 1.3 parts of selenium dioxide . The invention has the effects that the wood flame retardant is easy to penetrate into the solid wood, shortens the time required for the embryo body to soak in the pretreatment liquid, reduces the time cost required for production, and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a method for making a solid wood fire door. Background technique [0002] At present, with the development of society, people pay more and more attention to fire prevention, and fire doors emerge as the times require. In order to maintain the appearance, most families use solid wood fire doors. [0003] When the existing solid wood fire doors are made, the wood fire retardant is soaked into the wood structure of the fire door body mainly by soaking the fire door body in the treatment liquid containing the wood flame retardant, so that the wood has better flame retardant effect. [0004] The above-mentioned existing technical solutions have the following defects: solid wood is valuable wood, and generally the density of solid wood is relatively large, which itself has a good anti-seepage function, which makes it very difficult for the pretreatment solution to immerse in the so...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: solid wood is valuable wood, and generally the density of solid wood is relatively large, which itself has a good anti-seepage function, which makes it very difficult for the pretreatment solution to immerse in the solid wood, resulting in immersion. The depth is not ideal, and it needs to be soaked for a long time, which makes the processing time cost more during production, so there is still room for improvement
