example 1

[0030]Put poplar and birch into a four-sided planer in turn to process them into planks with a size of 320mm×160mm×23mm, put them in the sun after processing, and dry them naturally for 1 hour to obtain two test materials with a moisture content of 8% to 10%. , standby, polished the birch wood sample with sandpaper for 8 minutes, then evenly coated 80mL of 50% sodium silicate solution and 3g of silicon dioxide on the poplar wood sample according to the coating amount of 200g / m2, and then applied the poplar The wood test material was pasted on the surface of the birch wood test material, and then placed in a hot press molding machine after standing for 10 minutes. Under the conditions of hot pressing temperature of 10°C and pressure of 1.2 MPa, the hot pressing treatment was performed for 10 minutes to obtain a self-made composite test material. According to the mass ratio of 1:1, attapulgite and diatomaceous earth are mixed and ground to 100 mesh, and the sieved powder is colle...

[0032] Put the poplar and birch in the four-sided planer in turn to process them into planks with a size of 320mm×160mm×23mm, put them in the sun after processing, and dry them naturally for 1.5 hours to obtain two test materials with a moisture content of 9% for later use. , polished the birch wood sample with sandpaper for 9 minutes, and then uniformly coated 90mL of 50% sodium silicate solution and 4g of silicon dioxide on the poplar wood sample according to the coating amount of 250g / m2, and then the poplar wood sample The material was pasted on the surface of the birch test material, left to stand for 15 minutes, and then put into a hot press molding machine. Under the conditions of hot pressing temperature of 11°C and pressure of 1.4 MPa, the hot pressing treatment was performed for 13 minutes to obtain a self-made composite test material. Mix and grind attapulgite and diatomite with a ratio of 1:1 to pass through 150 meshes, collect the sieved powder, and place the sieve...

[0033] Put poplar and birch into a four-sided planer in turn to process them into planks with a size of 320mm×160mm×23mm, put them in the sun after processing, and dry them naturally for 2 hours to obtain two test materials with a moisture content of 10% for later use. Sand the birch sample with sandpaper for 10 minutes, then apply 100mL sodium silicate solution with a mass fraction of 50% and 5g of silicon dioxide evenly on the poplar sample according to the coating amount of 300g / m2, and then apply the poplar sample Stick it on the surface of the birch test material, let it stand for 20 minutes, put it into a hot press molding machine, and heat it for 16 minutes under the conditions of a hot pressing temperature of 12 ° C and a pressure of 1.6 MPa to obtain a self-made composite test material. Mix and grind attapulgite and diatomaceous earth at a ratio of 1:1 to pass through 200 meshes, collect the sieved powder, and place the sieved powder in a muffle furnace at 600°C for ca...

Abstract

The invention discloses a preparation method for a flame retardant smoke-inhibiting type solid wood composite floor and belongs to the technical field of furniture preparation. Self-made modified urea formaldehyde resin sol, self-made modified silicon sol and self-made modified screened powder are mixed and heated into a mixture, and the mixture can absorb heat to take away most of heat released by wood combustion in hot decomposing; boracic acid, borax and magnesium hydroxide continue to be added, wherein the boracic acid and the borax can promote char forming, inner woods are protected owing to char forming, and thus the smoke inhibiting effect is achieved; under the high temperature, glass-shaped coating films are formed on the surfaces of the woods, and the coating films can inhibit generation of combustible gas to achieve the smoke inhibiting effect; and magnesium hydroxide is added into a resin layer to constitute a wood veneer flame retardant agent layered alternately-arranged structure, in the combustion process, the magnesium hydroxide is decomposed to absorb heat released by adjacent veneers, a pyrolysis product, namely magnesium oxide, of the magnesium hydroxide is a fire-resistant material, transmitting of the heat and oxygen between the veneers is blocked again, and the flame retardant performance of the solid wood composite floor is further improved.

Description

technical field [0001] The invention discloses a method for preparing a flame-retardant and smoke-suppressing solid wood composite floor, which belongs to the technical field of furniture preparation. Background technique [0002] The solid wood composite floor is made of cross-laminated boards of different tree species, which overcomes the shortcomings of the solid wood floor's wet expansion and shrinkage to a certain extent. The dry shrinkage and wet expansion rate is small, and it has good dimensional stability. Natural wood grain and comfortable foot feel. [0003] Solid wood composite flooring national standard solid wood flooring main tree species solid wood composite flooring has a large difference in hardness, natural color and texture due to different materials. Solid wood composite flooring is a ground decoration material formed after drying and processing wood. Solid wood composite flooring has the characteristics of natural patterns, comfortable feet, and safe ...
