First, mix 60 parts of the obtained antibacterial plant fiber powder, 1 part of sperm powder, 10 parts of magnesium oxide, 5 parts of magnesium sulfide, 2 parts of modifier, and 2 parts of coagulant, then add water and stir evenly to obtain mixed raw materials. , and make the mixed raw materials into several layers of plate-shaped mixed raw materials.

Several layers of non-woven fabric core layers and several layers of plate-like mixed raw materials are laid at intervals and pressed into shape.

First, crush the plant straw into a powder of 40 to 200 mesh, so that the produced board can be more uniform, ensuring that the raw materials in the board are tightly connected after pressing. The mixed raw materials are composed of 60 parts of straw powder, 1 part of sperm powder, 10 parts of magnesium oxide, 5 parts of magnesium sulfide, 2 parts of modifier, and 2 parts of coagulant. After mixing, add water and stir evenly. Then the plant straw powder can It is tightly combined with the conditioner to ensure the strength of the plant fiber board after pressing, and accordingly reduces the corrosion of the board. When pressing the board, several layers of non-woven fabric core layers and several layers of plate-like mixed raw materials are laid at intervals. The non-woven fabric layer can increase the toughness of the board and avoid direct breakage of the plant fiber board.

Spray the upper and lower sides of the obtained plate with a silver ion antibacterial agent at a spray volume of 50ml/㎡, and keep it indoors at 20-30°C for 2 hours with a distance of 10cm~15cm between the two plates. Antibacterial effect, the substrate can be obtained after standing indoors for 4 to 6 hours.

Impregnated paper preparation process: Impregnated paper includes wear-resistant paper, patterned paper and balance paper. The resin impregnation amount of wear-resistant paper is controlled at 2 to 2.5 times of the base paper, the resin impregnation amount of pattern paper is controlled at 1 to 1.2 times of the base paper, and the resin impregnation amount of the balance paper is controlled at 1 to 1.2 times of the base paper. The amount of impregnation is controlled to be 1.2 to 1.8 times that of the base paper, and the glue is immersed in the glue respectively. After taking it out, it is cured to form impregnated paper with a pre-cured value of 30 to 60%.

The wear-resistant paper, balance paper and pattern paper cut to the appropriate size are hot-pressed and formed on the base material through a heat press. From bottom to top, the balance paper, base material, pattern paper and wear-resistant paper are formed, and the composite floor is obtained. The hot pressing temperature of the machine is 170~190℃, the hot pressing time is 25~35s, and the pressure is 16~9Mpa.

After cooling for 24 hours, the composite floor is cut into small pieces of wood according to the processing requirements, and the small pieces of wood are placed on the stacker for stacking. The stacking time is 5-7 days;

After curing, slotting and shaping are carried out. The wooden boards are slotted and shaped by four-sided planing and transverse double-end milling.

Coat the obtained small pieces with chamfering paint, and spray water-resistant wax on the side incisions with a spray volume of 18-20g/㎡. After cutting small pieces of board and opening the tongue and groove, the front and back surfaces of the board are affixed with hot-pressed decorative wear-resistant impregnated paper and balance layers, which have a certain protective effect. The four sides of the small board have weak protective effects. After opening the tongue and groove, The four sides are sprayed with water-resistant wax to enhance the protection of the four sides.
