Embodiment 1

[0015] A treatment process for improving the shape stability of wood handicrafts after processing and molding, the specific process method is as follows:

[0016] 1) Weigh an appropriate amount of melamine powder, put it in a crucible with a lid, put it into a muffle furnace, and calcinate at 500°C for 4 hours. After the calcination is completed, cool it down to room temperature naturally, then take out the product and grind it into powder To obtain graphite phase carbon nitride powder with an average particle size of 20um, add the obtained graphite phase carbon nitride powder into a chromic acid solution with a mass fraction of 0.05%, and ultrasonically vibrate for 30min at 50°C and 400W. After taking it out, wash it with distilled water until it is neutral, and dry it to obtain a pretreated graphite phase carbon nitride powder;

[0017] 2) According to the mass volume ratio of 1:60g / ml, dissolve P123 into the hydrochloric acid solution with a concentration of 1.3mol / L, stir ...

Embodiment 2

[0022] A treatment process for improving the shape stability of wood handicrafts after processing and molding, the specific process method is as follows:

[0023] 1) Weigh an appropriate amount of melamine powder, put it in a crucible with a lid, put it in a muffle furnace, and calcinate it at 520°C for 4.5h. Powder, to obtain graphite phase carbon nitride powder with an average particle size of 30um, add the obtained graphite phase carbon nitride powder to a chromic acid solution with a mass fraction of 0.08%, and ultrasonically vibrate for 40min at 55°C and 450W , taken out, washed with distilled water to neutrality, and dried to obtain pretreated graphite phase carbon nitride powder;

[0024] 2) According to the mass volume ratio of 1:65g / ml, dissolve P123 into the hydrochloric acid solution with a concentration of 1.5mol / L, stir at 32°C and 70r / min for 3.5h until P123 is completely dissolved, and then according to the total volume of the reaction system Add 3.5% of orthos...

Embodiment 3

[0029] A treatment process for improving the shape stability of wood handicrafts after processing and molding, the specific process method is as follows:

[0030] 1) Weigh an appropriate amount of melamine powder, put it in a crucible with a lid, put it in a muffle furnace, and calcinate at 550°C for 5 hours. After the calcination is completed, cool it down to room temperature naturally, then take out the product and grind it into powder To obtain graphite phase carbon nitride powder with an average particle size of 50um, add the obtained graphite phase carbon nitride powder into a chromic acid solution with a mass fraction of 0.1%, and ultrasonically vibrate for 50min at 60°C and 500W. After taking it out, wash it with distilled water until it is neutral, and dry it to obtain a pretreated graphite phase carbon nitride powder;

[0031] 2) According to the mass volume ratio of 1:70g / ml, dissolve P123 into the hydrochloric acid solution with a concentration of 1.7mol / L, stir at ...

Abstract

The invention discloses a treatment process for improving shaping stability of wood artware after processing and forming, and relates to the technical field of wood processing.The treatment process specifically comprises the following steps that 1, melamine is used for preparing graphite-phase carbon nitride, and then acid liquor treatment is conducted to obtain pretreated graphite-phase carbon nitride; 2) gear-shaped composite powder is prepared from P123, tetraethoxysilane and the pretreated graphite phase carbon nitride; 3) carrying out hydroxylation treatment on the gear-shaped composite powder; and 4) preparing impregnation liquid from aldehyde resin, distilled water, dextrin and hydroxylated gear-shaped composite powder, then performing vacuum pressure impregnation treatment on the wood artware, and then performing vacuum heat treatment. According to the treatment process provided by the invention, the slippage of a wood fiber molecular chain can be inhibited, so that the tendency of slow and permanent movement or deformation of the shaped wood is inhibited, and the improvement of the shaping stability of the wood artware is realized.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a treatment process for improving the shape stability of wood handicrafts after they are processed and shaped. Background technique [0002] As a low-carbon material, wood is widely used in construction, furniture and other industries. With the improvement of people's living standards, wood is gradually applied to the field of handicrafts. Wood handicrafts have high ornamental value and use value. The products are exported to foreign countries, loved by consumers, and have great market potential. In the process of processing wood crafts, in order to improve the plasticity of wood and diversify the shapes of processed crafts, it is necessary to soften the wood for better processing and shaping. After the wood handicraft is processed and shaped, it will tend to move slowly and permanently or deform under the influence of external factors, so that the shape of t...
