Example Embodiment
[0013] Example 1:
[0014] The high-density flame-retardant board of the present invention is made by the following steps:
[0015] a. Crush the cotton stalk to make cotton yarn with a length of 0.5-1 cm; crush the bamboo to make bamboo yarn with a length of 0.5-1 cm; according to the weight ratio of 100:10:10, the shavings and cotton The silk and bamboo silk are mixed evenly to make a board material;
[0016] b. Place the dried board material in a container containing flame retardant liquid and soak for 2 hours, and dry it after discharging to make the moisture content below 12%; the flame retardant liquid is composed of the following raw materials by weight percentage , Amidine urea phosphate 25%, borax 8%, ammonium dihydrogen phosphate 3%, alum 5%, styrene acrylic emulsion 5%, the balance is water;
[0017] c. Put the board material treated in step b into a container containing preservatives and dyes and soak for 4 hours, and dry after discharging to make the moisture content b...

Abstract
The invention relates to a flame retardant plank stuff with high density, which is manufactured by shavings and comprises the following steps of: a, uniformly mixing the shavings, cotton wires and bamboo wires according to a weight percentage of 100: 10:10 to manufacture a plank stuff; b, arranging the plank stuff into a container containing a flame retardant liquid and dipping for 1 to 4 hours; c, then putting the plank stuff into a container containing a preservative and a dyestuff and dipping for 1 to 4 hours; d, then arranging the plate material into a water-proof cementing compound and dipping for 1 to 2 hours; e, arranging the plank stuff after processed into the die of a pressure machine and shaping by cold pressing; f, drying, solidifying and demoulding. The flame retardant plank stuff with high density of the invention can be applied to the field of floors, furniture and building materials, can be manufactured into various colors and is an idealer base material; the fire resistance and corrosion resistance properties of the flame retardant plank stuff with high density can completely reach the national standards; besides, the flame retardant plank stuff with high density is characterized by high intensity and high density.
Description
Technical field: [0001] The invention relates to a particle board, in particular to a high-density flame-retardant board. Background technique: [0002] The density boards made of shavings currently used have low strength and are not suitable for high-end buildings. Second, it is not resistant to corrosion. The third is that the flame retardant effect is poor, and the fourth is that the product is not high-grade, and it cannot be made into plates of various colors according to the requirements of users. Invention content: [0003] In order to overcome the deficiencies of the following technologies, the present invention provides a high-density flame-retardant plate with high strength, fireproof and anti-corrosion properties that can fully meet the national requirements, and is suitable for the fields of floors, furniture and building materials. [0004] The present invention is achieved through the following measures: [0005] The high-density flame-retardant board of t...
