Preparation process of fireproof wooden door

Abstract

The invention discloses a preparation process of a fireproof wooden door, comprising the following steps: (1) preparing a fireproof coating, taking the following raw materials in parts by weight: 15-45 parts of water-based resin, 15-18 parts of nano-flame retardant coated with a polymer 10-15 parts of nitrogen-based flame retardant, 8-12 parts of melamine, 1-5 parts of modified ammonium polyphosphate, 1-4 parts of nano-silica, 2-5 parts of silicone-modified styrene-acrylic emulsion, dispersed 1-4 parts of antifoaming agent, 1-2 parts of defoamer, 1-2 parts of stabilizer, 4-6 parts of filler, 25-35 parts of water; Apply fire-resistant paint, then air-dry and apply topcoat, and then apply a layer of fire-resistant paint after the topcoat is air-dried. The invention has reasonable design, does not contain halogen flame retardant, has excellent fireproof performance, excellent physical and chemical properties, does not produce strong carcinogenic and toxic gas and smoke in case of fire, has small coating thickness, and is environmentally friendly and safe to prepare raw materials.

Description

technical field [0001] The invention belongs to the technical field of wooden door preparation, and in particular relates to a preparation process of a fireproof wooden door. Background technique [0002] With the continuous improvement of people's living standards, wooden doors have gradually developed from basic decoration and safety requirements to multi-functional requirements. Ordinary wooden doors should also have some specific functions for specific places of use. Since the essential materials of wooden doors are wood, Its fire-proof and flame-retardant properties are generally poor, which will increase the danger in the event of a fire, and its heat insulation performance is poor. [0003] At present, wood with better fire resistance performance is used to make fire doors, but its flame retardant and heat insulation performance is still not good, and the cost of the material itself is also high.

[0002] With the continuous improvement of people's living standards, wooden doors have gradually developed from basic decoration and safety requirements to multi-functional requirements. Ordinary wooden doors should also have some specific functions for specific places of use. Since the essential materials of wooden doors are wood, Its fire-proof and flame-retardant performance is generally poor, which will increase the danger in the event of a fire, and its heat insulation performance is poor.

[0003] At present, wood with better fire resistance is used to make fire doors, but its flame retardant and heat insulation performance is still not good, and the cost of the material itself is also high. Water-based coatings with flame retardant and heat insulation properties are used on the surface of wooden doors. will solve the above problems
