Problems solved by technology

[0003] Bamboo is a natural biomass material rich in starch and other polysaccharides. It is prone to decay and mildew during use, which not only affects the apparent quality of the product, but also seriously reduces the service life of the product.
Due to the poor permeability of bamboo itself, it is difficult to realize the long-term weather resistance of products through conventional chemical immersion and brushing anti-corrosion and anti-mildew treatments. Therefore, the existing technology mostly uses high-temperature steam carbonization to pretreat bamboo. It can improve the weather resistance of bamboo recombined wood, but the product is dark brown, losing the warm and pleasant natural color of bamboo, and the processing energy consumption is high, and the mechanical strength of the product will also be significantly reduced, resulting in its use in many high-strength requirements. Field applications are limited, which ultimately severely restricts the further expansion of product application fields and the improvement of market competitiveness

Embodiment 1

[0046] A kind of manufacture method of outdoor high-weather-resistant bamboo quality reconstituted material of the present invention, such as figure 1 shown, including the following steps:

[0047] S1, biological pretreatment

[0048] S1.1, preparation of bamboo bundles: sawing fresh moso bamboo into bamboo tubes with a length of 2.15m, using a bamboo tube splitting machine to split it into bamboo strips with a width of 30mm, after removing the green and yellowing treatment, and then using the bamboo chip disintegrating machine The bamboo strips are processed into bamboo bundles to obtain a horizontally loose and longitudinally connected bamboo bundle unit.

[0049] S1.2. High-temperature steam sterilization treatment: put the bamboo bundle unit in an autoclave with a temperature of 115°C, sterilize it with high-temperature steam for 30 minutes, take it out, and immediately transfer it to a sterilized constant temperature and humidity room for use. The high temperature stea...

Embodiment 2

[0070] A manufacturing method of outdoor high-weather-resistant bamboo quality reconstituted material of the present invention, comprising the following steps:

[0071] S1, biological pretreatment

[0072] S1.1. Preparation of bamboo stalks: sawing fresh moso bamboo into bamboo tubes with a length of 1.55m, using a bamboo tube splitting machine to split it into bamboo strips with a width of 15mm, and then using a bamboo splitting machine to cut the bamboo strips along the radial direction. The direction is divided into thin bamboos with a thickness of 1-2 mm, and bamboos are obtained.

[0073] S1.2, high-temperature steam sterilization treatment: place the above-mentioned bamboo stalk unit in an autoclave with a temperature of 120 ° C, take out after 20min of high-temperature steam sterilization, and immediately transfer to a sterilized constant temperature and humidity room in standby. The high temperature sterilization treatment is to kill other miscellaneous bacteria carr...

Abstract

The invention discloses an outdoor high-weather-resistance bamboo scrimber and a manufacturing method thereof.The manufacturing method comprises the steps that bamboo units are sequentially subjected to high-temperature steam sterilization treatment, biological pretreatment, primary cooking treatment, saturated steam carbonization treatment and secondary cooking treatment, and then the mildew-proof and corrosion-proof bamboo units are obtained; and carrying out gum dipping treatment, drying and balancing treatment, assembling, hot-pressing forming and post-treatment to obtain the outdoor high-weather-resistance bamboo scrimber. The outdoor high-weather-resistance bamboo scrimber has the advantages of being high in weather resistance, high in strength, close to the color of bamboo wood and the like, can meet the requirements for production and manufacturing of outdoor bamboo engineering materials and engineering components, and can be widely applied to the field of modern bamboo structure building engineering.

Description

technical field [0001] The invention belongs to the field of bamboo-wood composite reconstituted bamboo material manufacturing in the wood industry, relates to an outdoor bamboo reconstituted material and a manufacturing method thereof, and in particular relates to an outdoor high-weather-resistant bamboo reconstituted material with high strength and strong weather resistance and its manufacture method. Background technique [0002] Bamboo has the characteristics of abundant resources, short growth cycle and high strength-to-weight ratio. Under the background of increasing scarcity of wood resources, rational development and utilization of bamboo resources has become an important way to alleviate the shortage of wood resources. Driven by the development concept of "replacing wood with bamboo", using bamboo as raw material, it is divided into bamboo strips or loosened into bamboo bundles. The controllable board has excellent mechanical properties similar to wood, but also ov...
