Problems solved by technology

[0003] At present, the important steps in the process of producing bamboo plywood are drying, dipping, billet formation, hot pressing and other steps. Due to the water content of bamboo, hot pressing temperature, dipping amount, and billet formation method, etc. will affect the performance of the board. These factors are difficult to control, resulting in the gradual decline in the strength, elastic modulus and load-bearing capacity of the bamboo plywood as the use time increases, and it is easy to deform. In some fields that require high mechanical properties of the board App is restricted

Embodiment Construction

[0019] The utility model relates to a high-strength bamboo plywood, which is composed of a carbon fiber cloth middle core layer and alternately stacked slat curtains and bamboo silk curtains.

[0020] A kind of production technology of described high-strength bamboo plywood comprises the following steps:

[0021] (1) Choose young and strong bamboos that are more than three years old, cut them, break them, remove the bamboo joints, remove the green layer and yellow layer, and then split them into pieces with a thickness of 1mm and a width of 20mm;

[0022] (2) Take part of the strips and weave them into bamboo curtains with threads to make bamboo curtains, dry them once, and the moisture content is ≤ 10%, then dip the bamboo curtains in glue, dry them for the second time, and set them aside;

[0023] (3) The remaining pieces are made into bamboo silk by a wire pressing machine. The width of the bamboo silk is 1mm and the thickness is 1mm. The bamboo silk and the nylon fiber wit...

Abstract

The invention discloses high-strength bamboo plywood. The high-strength bamboo plywood is formed in the manner that carbon fiber cloth is used as a core layer, bamboo skin curtains and bamboo filament curtains mixed with nylon fiber in a woven manner are alternately stacked and bonded, and hot pressing is conducted, and a production technology of the high-strength bamboo plywood is provided. Phenolic resin glue mixed with micron sized silica aerogel is used as a sizing agent, so that the defects that the phenolic resin glue is large in fragility, poor in creep resistance and the like are relieved. The manufactured bamboo plywood is better than bamboo plywood produced by the adoption of a traditional technology in the aspects of loading capacity, deformation resistance, heat resistance and the like, and the economic value of the bamboo plywood is effectively improved.

Description

technical field [0001] The invention relates to the technical field of bamboo plywood, in particular to a high-strength bamboo plywood. Background technique [0002] Timber resources are becoming increasingly tense worldwide, and bamboo is currently the only green material that is recognized as a substitute for timber resources. With the improvement of the level of industrialization, the development of bamboo has been greatly developed, and products such as bamboo plywood and bamboo strip lumber emerge in an endless stream. These materials can meet the performance requirements of various houses and structural components, to a certain extent. Alleviate the shortage of timber supply. The Ministry of Construction even included bamboo plywood in the top ten new technology product promotion projects, which greatly promoted the development of the bamboo market. Bamboo composite panels are widely used in vehicles, construction, shipbuilding, decoration and other fields, which ful...
