Bamboo and wood alternately arranged composite board and its manufacturing method

Abstract

The invention discloses a bamboo and wood interface compound board, which includes lengthwise arranged bamboo pieces and transverse arranged wood single boards. The bamboo piece and the single wood boards are compounded together layer by layer from outside in; the external layer is made up of three layers of bamboo pieces, the core layer is made p of single layer wood board and two layers of bamboo pieces. They are also can be compounded: the external layer is one bamboo banquet, the core layer is made up of single layer board and two layers of bamboo pieces, the furthest layer is bamboo piece. The compressing rate is more than 25%, the intensity is more than 21kg / cm2, the static bending modulus is more than 1000kg / cm2, the elastic modulus is more than 100ton / cm2.

Description

1. Technical field [0001] The invention relates to a composite board and a manufacturing method thereof, in particular to a bamboo-wood composite board and a manufacturing method thereof which can meet the requirements of the bottom plate of a container. 2. Background technology: [0002] In the past fifteen years, the container manufacturing industry has been fully transferred from Europe, America, Japan, and Southeast Asia to China. According to statistics in 2003, China's container production accounted for 94% of the world's total, and the annual import of supporting tropical rainforest hardwood floors reached 1.8 million sets, equivalent to 1.4 million cubic meters of tropical rainforest being cut down. Under the pressure of international environmental protection policies, many countries and enterprises have invested in the development of green panels to reduce the loss of rainforest. Bamboo forests in my country are rich and fast-growing for four years, which is an eff...

Problems solved by technology

In 1998, Nanjing Forestry University and Hong Kong Diqin jointly developed a bamboo-wood glued container floor and applied for a patent. The patent number is ZL98111153.X. The base board was affected by the national "Natural Protection Project" policy, the wood was in short supply, and the cost increased, so it was switched to small-diameter wood, but the production was stopped due to the decline in product strength
