Embodiment 1

[0018] see Figure 1-2 , the present invention provides a kind of technical scheme: a kind of nano-ZnO coating improves the aging resistance treatment process of balsa wood, comprises the following steps:

[0019] A, first place the balsa wood in the drying box;

[0020] B, then the balsa wood after heat treatment is placed in nanometer zinc oxide suspension solution and carries out impregnation treatment;

[0021] C, the balsa wood sample after impregnation treatment is placed in blast drier to carry out drying treatment;

[0022] D. Finally dry until the weight of the sample remains unchanged.

[0023] In this embodiment, in step A, the drying oven treatment temperature ranges from 60-110° C., and the treatment time is 6 hours.

[0024] In this example, in step B, the balsa wood should be impregnated with nano-zinc oxide suspension solution, the weight ratio of ZnO is 2%, the treatment temperature is 50°C, and the treatment time is 1 day; a stirring device is used for sti...

Abstract

The invention discloses a treatment process for improving aging resistance of cork wood by using a nano ZnO coating. Firstly, the cork wood is placed in a drying box; wherein the treatment temperatureranges from 60 DEG C to 110 DEG C; wherein the treatment time is 2-24 hours; then, the cork wood subjected to heat treatment is put into a nano ZnO suspension liquid to be subjected to dipping treatment; in order to ensure the stability of the ZnO suspension liquid, a stirring device is adopted for stirring in the dipping process, the treatment temperature is 30-50 DEG C, the treatment time is 1-2 days, a dipped cork wood sample is placed in an air blowing dryer to be dried, heat preservation is conducted for 12-36 hours at the temperature of 80 DEG C below, furnace cooling is conducted to the room temperature, and finally drying is conducted till the weight of the sample is not changed. The anti-aging treatment of the cork wood can be realized, the process is simple, and the operation isconvenient.

Description

technical field [0001] The invention relates to the technical field of material aging resistance treatment, in particular to a nano-ZnO coating to improve the aging resistance treatment process of balsa wood. Background technique [0002] Balsa wood (Ochroma pramidale) is the lightest wood in nature and one of the fastest growing tree species in the world. It can be harvested in 5 years, with an average stock volume of 400 m 3 / hm 2 . Like other fast-growing tree species, balsa also has defects such as loose wood, low strength, and perishability. When wood is used as indoor and outdoor materials, it is often affected by surrounding environmental factors and deteriorates. Especially outdoor materials will undergo slow and complex physical and chemical changes on the surface under the action of solar radiation, which will lead to changes in wood color. The change of color not only affects the quality of wood and affects the aesthetic feeling, but also greatly reduces the us...
