Embodiment Construction

[0032] The present invention will be further described below through embodiment and accompanying drawing. It should be noted that these embodiments are not intended to limit the protection scope of the present invention, and the protection scope of the present invention shall prevail in the appended claims.

[0033]After the miscellaneous bamboo is rolled and combed to remove part of the bamboo wax on the surface, the miscellaneous bamboo is sliced ​​by a disc-type bamboo wood chipper, and the temperature is 120°C. NaOH accounts for 5% of the weight of the bamboo slices and pressurized for 0.5 MPa cooking 15min, the bamboo chip that the cooking is crossed is dropped into QM6 thermal grinder and carry out thermal grinding and defibrating, obtain bamboo fiber and dry; To the bamboo fiber spraying 21.5 weight parts of 100 weight parts by 5 weight parts antifungal agents, 1.5 weight parts part curing agent, 3 parts by weight paraffin emulsion waterproofing agent and 12 parts by we...

Abstract

The invention relates to a bamboo middle-density fiber plate, made from bamboo and Japanese cedar, wherein it is formed by 50-95 Japanese cedar sheets, 1-100 bamboo sheets, 8-15 urea-formaldehyde glue, 0.5-5 anti-fungus agent, 0.2-3 solidifier, and 1-3 ceresin wax. And its preparation comprises that: putting bamboo sheets into solution while NaOH is 1-5% of bamboo weight; at 80-130Deg. C and 0.5MPa pressure, boiling it for 10-15min, to be mixed with Japanese cedar sheets, to be grinded and dried; plating urea-formaldehyde glue added with anti-fungus agent, solidifier and wax emulsion on the fiber to be thermally compressed.

Description

Technical field: [0001] The invention relates to a medium density fiberboard, in particular to a bamboo medium density fiberboard made from miscellaneous bamboo. technical background: [0002] Fiberboard is a wooden board product made by sizing wood fibers and hot pressing, especially with a density of 0.45-0.88g / cm 3 Among them, medium density fiberboard (MDF) is widely used as a base material for furniture and flooring because of its low price and good performance. With the development of the national economy, it stimulates the continuous growth of the furniture and laminate flooring manufacturing industry, and the demand for MDF is also increasing. [0003] However, my country is a country with a relative lack of forest resources, and the supply of timber raw materials is tight. Especially, the country implements natural forest protection projects and implements a comprehensive ban on logging. Therefore, many MDF manufacturers have been or will soon face the threat of s...
