Technical Field

The invention belongs to the technical field of gardens, and particularly relates to an elastic garden preservative wood and a preparation method thereof.

Background

the anticorrosion wood is characterized in that after a chemical preservative is artificially added to common wood, the common wood has the characteristics of corrosion resistance, moisture resistance, fungus resistance, insect and ant resistance, mildew resistance, water resistance and the like; the common domestic anticorrosion wood mainly comprises two materials: russian pinus sylvestris and Pinus koraiensis.

The anti-corrosion wood flower shelf can be in direct contact with soil and a humid environment, is often used on an outdoor floor, is an ideal material for outdoor floors, garden landscapes, wooden swings, entertainment facilities, wooden trestles and the like, is used for people to rest and enjoy natural beauty, is deeply favored by gardening designers, but is very environment-friendly along with the development of scientific technology, so that the anti-corrosion wood flower shelf is also often used in indoor decoration, floors and furniture, and indoor decoration designers also like the anti-corrosion wood very much.

Modern society pursues fashionable, rhythmic and concise life, so that the garden landscape is consistent with the era; the anticorrosion wood which is a landscape integrating nature, ecology and elegance is a new landscape material with wide application, and is more and more advocated and loved by people; the technology of anticorrosion wood is developed along with the chemical industry, and as the name suggests, the wood is a wood capable of preventing corrosion, water and ants, and is an outdoor anticorrosion wood which presses the antiseptic into the wood by vacuum force through a closed pressure anticorrosion tank.

however, in the preparation process of the traditional preservative wood, the preservative cannot be fully and completely fixed in the wood, in the use process, rainwater or factors cause the preservative wood to be soaked in water for a long time or be in humid air for a long time, so that the water content of the wood is increased, the moisture exists, the preservative is slowly lost, on one hand, the water is polluted by the preservative, on the other hand, various wood rot fungi in the wood can rapidly grow, the wood rot fungi can degrade the wood, the strength of the wood is further reduced, even the wood is completely lost, and the elasticity of the general preservative wood is not obviously strengthened, so that the design and use requirements cannot be well met.
