Wood-plastic recombined bamboo multi-component composite building component with buffering part and manufacturing method

Abstract

The manufacturing method of the wood-plastic recombined bamboo multi-component composite building component with the buffering part comprises the steps that bamboo materials are machined and recombined at high temperature to form recombined bamboo blocks, and paired through or non-through reserved holes are formed in the specific positions of the recombined bamboo blocks to serve as U-shaped bolt containing cavities; c-shaped steel is placed on the upper portion, the middle portion and the lower portion of the recombined bamboo block and aligned with the U-shaped bolt containing cavities reserved in the recombined bamboo block, and the C-shaped steel is connected with the recombined bamboo block through U-shaped bolts; a WPC base material is prepared from, by mass, 20-60 parts of HDPE, 40-80 parts of bamboo fiber powder and other materials, the WPC base material is made into a wood-plastic shell through an extrusion molding technology, and the product prepared in the previous step is embedded into the wood-plastic shell; and the mixture is combined with polyurethane to obtain a complete component. The building material has stronger compression resistance and longer service life, and can effectively shorten the building cycle and reduce the generation of building wastes.

Description

technical field [0001] The invention relates to the field of prefabricated building parts, in particular to a column part in a prefabricated building and a manufacturing method thereof, specifically a wood-plastic recombined bamboo multi-component composite building column part with a polyurethane buffer and a manufacturing method thereof. Background technique [0002] With the development of independent research and development technology of new building materials in China, the application of new building materials is becoming more and more extensive; the rapid development of the construction industry has more and more functional requirements for building parts, especially for sustainable development, green and low carbon Special emphasis is placed on the development of building components. [0003] Compared with concrete and steel, bamboo is a typical green low-carbon material with superior performance. However, as a biomass material, bamboo contains a large amount of lig...
