Embodiment 1

[0032] figure 1 , the structure of a bamboo-based railway box car liner is that the surface layer is a layer of fire-resistant board 8, and the bottom layer is a bamboo-based panel coated with urea-formaldehyde glue added with white latex. The structure of the bamboo-based panel is that the surface layer is a layer. A layer of bamboo mat 1 impregnated with phenolic glue and dried at low temperature, the lower layer is a layer of vertical grain bamboo curtain 2 impregnated with phenolic glue and dried at low temperature, the thickness of which is 0.8-1.5mm; Low-temperature-dried transverse-textured bamboo curtain 3, the thickness of which is 0.8-1.5 mm; and then down to two layers of transverse-grained bamboo curtain 2 impregnated with phenolic glue and dried at low temperature.

[0033] The manufacturing method is as follows:

[0034]a. Longitudinal texture bamboo curtain 2, horizontal texture bamboo curtain 3, bamboo mat 1, the thickness of which is 0.8-1.5mm; sorting and so...

Embodiment 2

[0039] figure 2 , a bamboo-based railway boxcar inner liner, the outer layer is the first melamine impregnated paper 4 impregnated with phenolic glue and dried at low temperature, the lower layer is a horizontal textured wood veneer 6 coated with phenolic glue, and then downwards is The longitudinal texture wooden veneer 5 coated with phenolic glue, the next layer is a horizontal textured wooden veneer 6, and the next layer is a bamboo mat 1 impregnated with phenolic glue and dried at low temperature, and the next layer is the second melamine Impregnated paper7.

[0040] The manufacturing method is as follows:

[0041] a. Sorting and sorting the longitudinal grain wooden veneer 5, the transverse grain wooden veneer 6 and the bamboo mat 1, drying the longitudinal grain wooden veneer 5 and the transverse grain wooden veneer 6 until the moisture content is below 8%, and coating both sides with phenolic Glue; Bamboo mat 1 is dried to a moisture content below 12%, impregnated wi...

Embodiment 3

[0044] image 3 , a bamboo-based railway boxcar inner liner, the outer layer is the first melamine-impregnated paper 4 impregnated with phenolic glue and dried at low temperature, the bottom layer is a longitudinal grain wood veneer 5 coated with phenolic glue, and then downwards is The horizontal texture wooden veneer 6 coated with phenolic glue, then downwards is the longitudinal textured wooden veneer 5 coated with phenolic glue, and then the horizontal textured wooden veneer 6 coated with phenolic glue for the next layer, and then downwards The next layer is the vertical grain wood veneer 5 coated with phenolic glue, and then down is a layer of bamboo mat 1 impregnated with phenolic glue and dried at low temperature, and then down is a second layer of melamine-impregnated paper 7.

[0045] The manufacturing method is as follows:

[0046] a. Wooden veneer with longitudinal grain 5, wooden veneer with transverse grain 6, bamboo mat 1 sorting and sorting, wood veneer with lo...

Abstract

The invention relates to the fields of manufacturing technology and application artificial board and discloses a bamboo-based interior lining board of a railway boxcar and a manufacturing method of the interior lining board. The bamboo-based interior lining board of the railway boxcar comprises a bamboo artificial board and a refractory board, wherein the bamboo artificial board comprises a plurality of layers; the outer layer is a bamboo mat which is soaked with phenolic aldehyde glue and dried at low temperature; one layer of longitudinal texture bamboo curtain which is soaked with phenolic aldehyde glue and dried at low temperature is arranged below the bamboo mat; one layer of transverse texture bamboo curtain which is soaked with phenolic aldehyde glue and dried at low temperature is arranged below the longitudinal texture bamboo curtain; and two layers of longitudinal texture bamboo curtains which are soaked with phenolic aldehyde glue and dried at low temperature are arranged below the transverse texture bamboo curtain. The bamboo-based interior lining board of the railway boxcar has high mechanical property and low water absorption expansion rate, has the advantages of high surface hardness, high wear resistance, excellent aesthetic degree, high impact resistance and no need of paint, and can be manufactured by selecting the width size of the bamboo-based artificial board as required.

Description

technical field [0001] The invention relates to the field of man-made board manufacturing technology and application, in particular to a bamboo-based railway box car inner lining board and a manufacturing method thereof. Background technique [0002] Due to the needs of carrying goods, the railway box car requires the inner lining board of the car inner wall to have certain mechanical properties, appearance quality, impact resistance, wear resistance and insect rot resistance. For a long time, the inner lining boards of railway boxcars have been mainly made of bamboo strip plywood. The current bamboo mat plywood is made of multi-layer bamboo mats impregnated with phenolic glue—bamboo curtains. Because bamboo mats and bamboo curtains are mostly purchased in small workshops in mountainous areas , relying on natural drying, more or less mildew occurs, and the glue is not uniform after dipping, the surface of the extruded bamboo mat plywood is not beautiful, and it is easy to be...
