Abstract

The invention discloses a pretreatment method of a cunninghamia lanceolata floor board material. The method comprises the following steps of S1, performing oil treatment on the cunninghamia lanceolatafloor board material; soaking the cunninghamia lanceolata floor board material into plant oil; S2, taking out the soaked cunninghamia lanceolata floor board material; performing drying treatment; S3,performing secondary oil treatment on the cunninghamia lanceolata floor board material dried in the step S2; soaking the cunninghamia lanceolata floor board material treated in the step S2 into the plant oil again; S4, performing still standing on the cunninghamia lanceolata floor board material treated in the step S3 under the vacuum condition; S5, putting bamboo sheets obtained in the step S4 into ethanol; S6, putting the cunninghamia lanceolata floor board material for 5 to 10h in the environment being 40 to 50 DEG C at the pressure being 1.2 to 1.5MPa; S7, drying the cunninghamia lanceolata floor board material treated in the step S6; ensuring the moisture content being 2 to 3 percent. The pretreatment method of the cunninghamia lanceolata floor board material disclosed by the invention has the advantages that the process design is scientific and reasonable; according to the self performance characteristics of the cunninghamia lanceolata, the scientific method is used for modifying the cunninghamia lanceolata floor board material; the cunninghamia lanceolata is enabled to have good performance; cracking and deformation cannot occur; the stability of the cunninghamia lanceolatafloor board material is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a pretreatment method for fir flooring materials. Background technique [0002] Chinese fir (Cunninghamia Lanceolata) is a unique fast-growing commercial timber tree species in my country. It grows fast and has good materials. It is artificially cultivated in large quantities at the Dafeng fir base. The wood texture is straight, the structure is uniform, not warped or cracked, the bulk density of the wood is 0.39, the average number of annual rings per centimeter is 3.0, the rate of late wood is 22.0%, the drying shrinkage coefficient (volume) is 0.386, and the ultimate compressive strength along the grain is 358 kg / cm2 , the static bending limit strength is 661 kg / cm2, and the end face strength is 285 kg / cm2. The material is light and tough, with moderate strength and high quality coefficient. It has a fragrance, and the wood contains "Shannao", which can resist ins...
