Recyclable environment-friendly mulberry fiber board

Abstract

The invention relates to the board technology, in particular to a recyclable environment-friendly mulberry fiber board. Mulberry fibers and sheet-shaped mulberry trunks are in hot press molding through adhesives. The production method comprises the steps that (1) a mulberry tree is peeled, so that mulberry bark and a mulberry trunk are obtained; (2) the mulberry bark is smashed after being dehydrated to obtain the mulberry fibers, and the mulberry trunk is smashed after being dehydrated to obtain the sheet-shaped mulberry trunks; (3) the mulberry fibers and the sheet-shaped mulberry trunks are subjected to ungrease treatment, and then washing, filtering and drying are conducted; (4) the degreased mulberry fibers and the sheet-shaped mulberry trunks are mixed in a rolling mode, acrylic emulsion is added, rolling mixing and preheating are conducted, and then an anti-caking modifying agent and a curing agent are added; (5) modularization forming is conducted on the mixture in the fourth step, and then cold pressing dehydration and hot pressing solidifying are carried out. According to the recyclable environment-friendly mulberry fiber board, raw material supply of goods is sufficient, collecting is convenient, cost is low, the processing technology is simple, compared with a fiber plate in the current market, the nail-holding ability is improved substantially, the moisture proof performance is obviously improved, the board can be recycled after being smashed, and the board is more economical and environmentally friendly.

Description

technical field [0001] The invention relates to board technology, in particular to a recyclable and environmentally friendly mulberry fiber board. Background technique [0002] In traditional sericulture, the mulberry branches that need to be cut every year are generally burned as fuelwood or directly discarded in the field, causing a lot of waste and pollution. If mulberry branches are used as raw materials to produce and process MDF, it not only finds a cheap source of raw materials for MDF, but also saves a lot of wood resources. increase income. [0003] In addition to solid wood boards, fiberboards are commonly used in the market at present. Solid wood boards are expensive and consume a lot of materials, but the main disadvantages of fiberboards are: 1. Not moisture-proof, they will swell when exposed to water. 2. The density board has a large deformation, and the long-term load-bearing deformation is larger than that of the homogeneous solid wood particle board. 3. ...

Problems solved by technology

[0003] In addition to solid wood boards, fiberboards are commonly used in the market at present. Solid wood boards are expensive and consume a lot of materials, while the main disadvantages of fiberboards are: 1. Not moisture-proof, they will swell when exposed to water

2. The density board has a large deformation, and the long-term load-bearing deformation is larger than that of the homogeneous solid wood particle board

3. The density board has poor nail holding power. Because the fibers of the density board are very broken, the nail holding power of the density board is much worse than that of solid wood board and particle board.
