Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials, and in particular relates to a cement imitation wood and a preparation method thereof. Background technique [0002] As a natural resource, wood is the most used substance by humans. Due to the use of a large amount of wood, it is easy to lead to a rapid reduction in the area of ​​tropical rainforest. In addition to making wood an increasingly expensive material, it also causes serious damage to the earth's ecological environment. However, due to the characteristics of wood materials , and its texture, which has been loved by the world for a long time, is difficult to be replaced by other materials, so the demand for wood has not decreased yet. The disadvantages of wooden boards are that they are not wear-resistant, not fireproof, perishable, easy to be eaten by insects, and expensive. [0003] People have always had a strong pursuit of solid wood products, but according...
