Problems solved by technology

[0002] With the improvement of people's living standards, people are increasingly demanding natural simplicity, elegant appearance, and trendy fashion for the decoration and construction of their living or office spaces and public places (such as boutiques, supermarkets, etc.). Consume a lot of bamboo and wood resources
In order to solve the problem of insufficient resources such as wood and bamboo, the most commonly used method is to use small-diameter branch wood, fast-growing wood, leftovers from bamboo factories, leftovers from wood factories, bamboo bran, bark, crop poles, waste bamboo, etc. Low-grade wood-based panels such as particleboard, medium-density fiberboard, and wood bran fiber particleboard can be made from raw materials and waste wood. , plywood) compared to
Thereby causing a large amount of waste of these bamboo timber resources

Embodiment 1

[0107] As mentioned above figure 2 The shown process uses Salix branches to form a formaldehyde-free fiber material, where the conditions of the milling are such that the diameter of the filaments of the sand willow branches after rolling is 0.05mm (85-88% by weight of the fiber filaments remain adhered after rolling) , Through the formaldehyde-free binder HansiT extruded in the glue spraying device, the fibers of the milled Salix branches are bonded into a whole (that is, the fibers are bonded to each other along the length direction of the fiber filaments), and the drying device Dry the shredded Salix branches supplemented with the formaldehyde-free binder so that the water content of the shredded Salix branches is 3% by weight, and then dry and bond them together by a cutting device The shredded sand willow branches are cut into the required size of the shredded sand willow branch layer (thickness is 0.1cm), and then the shredded sand willow branch layer is alternately laid ...

Embodiment 2

[0109] The formaldehyde-free fiber material was formed according to the method of Example 1. The difference is that the conditions of the milling are such that the diameter of the filaments of the sand willow branches after the milling is 0.001mm (83-85% by weight of the fiber filaments after the milling remain adhered ), where the internal bonding strength of the obtained formaldehyde-free fiber material is 0.55MPa, and other performance indicators such as static bending strength, surface bonding strength, water absorption thickness expansion rate, density deviation, etc. are better than those of the prior art wood-based panels The standard is sufficient to meet the requirements of GB / T11718-1999 on the physical and mechanical properties of indoor slabs.

Embodiment 3

[0111] The formaldehyde-free fiber material was formed according to the method of Example 1. The difference is that the conditions of the milling are such that the diameter of the filaments of the sand willow branches after the milling is 0.1mm (88-90% by weight of the fiber filaments after the milling remain adhered ), where the internal bonding strength of the obtained formaldehyde-free fiber material is 0.5MPa, and other performance indicators such as static bending strength, surface bonding strength, water absorption thickness expansion rate, density deviation, etc. are better than those of prior art wood-based panels The standard is sufficient to meet the requirements of GB / T11718-1999 on the physical and mechanical properties of indoor slabs.

Abstract

A fibrous material containing no formaldehyde and formation method thereof, comprising: milling the fibrous raw material so as to loosen the fibers thereof and retain adhesiveness thereof; forming alternate layers of the milled fibrous raw material and an adhesive containing no formaldehyde, the upper and lower surface layers being formed from milled fibrous raw material, then hot-pressing and cold-pressing the material in sequence. Also provided are a decorative fibrous material and a method of manufacture thereof. The method of the present invention makes use of the small-diameter branches of the sand willow (Salix mongolica) and other trees to manufacture the decorative fibrous material. Simple and requiring no special equipment, the method is suitable for large-scale industrial production.

Description

Technical field [0001] The invention relates to a formaldehyde-free fiber material and a forming method thereof, and a fiber decoration material and a manufacturing method thereof. Background technique [0002] With the improvement of people’s living standards, people’s decoration and construction of their living or office places, public places (such as boutiques, supermarkets, etc.) are also increasingly requiring natural simplicity, beauty, and trendy fashion. Therefore, this will undoubtedly Consume a lot of bamboo and wood resources. In order to solve the problem of insufficient resources such as wood and bamboo, the most commonly used method is to use small-diameter branches, fast-growing materials, leftover materials from bamboo mills, leftover materials from wood mills, bamboo stalks, bark, crop poles, and discarded bamboo. Low-grade man-made boards such as particleboard, medium-density fiberboard, and wood-cash-fiber particleboard are made of raw materials and waste wood...
