Problems solved by technology

[0003] However, in the 21st century, fiberboard companies have found that the society has put forward higher requirements for them: the first is the issue of clean production. Like other industrial enterprises, using the existing technology for producing fiberboards, they must produce Certain pollutants will pollute the environment; secondly, due to the low cost of fiberboard and its ease of use and convenience, many fields of production and life are looking forward to the emergence of new fiberboards with better performance to meet the various needs of users

Embodiment 1

[0044] A method for manufacturing a high-strength fiberboard, comprising the steps of:

[0045] 1) Weigh 10 parts of magnesium chloride, 15 parts of beryllium oxide and 10 parts of zirconium oxide by weight percentage, and control their particle size within the range of 100-150 meshes, pour them into a mixer to obtain uniform mixed powder;

[0046] 2) Add ammonia water and a small amount of water to the mixed powder obtained in step 1), adjust the pH value of the mixed powder to 8, and obtain an alkaline mixed solution;

[0047] 3) Place crude fibers with a water content of 8% in a glue mixer, and during the fiber stirring process, evenly spray binders and thickeners on the surface of the crude fibers to obtain crude fibers, wherein the viscous The spraying amount of binding agent is 10% of crude fiber gross weight; Described bonding agent is lignin; Described thickening agent is hydroxyethyl cellulose;

[0048] 4) Place the alkaline mixed solution in step 2) in a rubber mixi...

Embodiment 2

[0053] Repeat Example 1, with the following differences: take by weight 15 parts of magnesium chloride, 18 parts of beryllium oxide and 8 parts of zirconium oxide, and control their particle size within the scope of 150-200 objects, and pour them into a mixer to obtain a uniform Mixed powder, test results are shown in Table 1.

Embodiment 3

[0055] Repeat Example 1 with the following differences: sodium hydroxide and a small amount of water are added to the mixed powder obtained to adjust the pH value of the mixed powder to 9 to obtain an alkaline mixed solution. The test results are shown in Table 1.

Abstract

The invention discloses a high-strength fiberboard. The high-strength fiberboard is prepared from the following raw materials in parts by weight: 10 to 15 parts of magnesium chloride, 15 to 20 parts of beryllium oxide, 8 to 10 parts of zirconium oxide, 35 to 45 parts of crude fibers, 3 to 5 parts of alkaline solution, 8 to 12 parts of binder and 2 to 5 parts of thickening agent. The application provides the high-strength fiberboard and a manufacturing method thereof. The fiberboard has the characteristics of relatively-high stability and compression strength and the like; in addition, no pollutants are produced in the manufacturing process of the high-strength fiberboard and no pollution to the environment is caused.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-strength fiberboard and a manufacturing method thereof. Background technique [0002] The invention of wood-based panels occupies an extremely important position in the history of human invention and development. Wood-based panels, together with other materials, have laid a solid material foundation for modern civilization. At present, wood-based panels have formed dozens of different types of wood-based panel material systems in three major categories: plywood, particleboard, and fiberboard, and they play an irreplaceable role in many industries. Since the reform and opening up, due to the wide use of wood-based panels, the development of China's wood-based panel industry has been vigorous, with an annual growth rate of nearly 25%. In just a few decades, the output of wood-based panels has leapt to the forefront of the world. [0003] However, in the 21st century, fiberboard com...
