Wood-bamboo straw fiberboard and composite board and post wet-method production technique

Abstract

The invention discloses a wood-bamboo-straw fiber board, and belongs to the technical field of forest product manufacturing. The fiber board is made from any one or two sorts of fiber materials from wood, bamboo, straw, or natural biological insect-resist agents including tobacco stick and the like, 3 to 5 percent of preservative, additives such as treating compound, reinforcing agent, waterproof agent and the like, 12 to 40 percent of fiber soakage moisture content, 6 percent of reinforcing agent starch, 0.5 to 1 percent of waterproof agent wax and rosin latex and 1 to 3 percent of hard board reinforcing agent; and the density of the mixture is controlled to be between 380KG / m<3> and 1,200 KG / m<3> so as to be made into the fiber board. Meanwhile, a preparation method provided reduces wood consumption, makes comprehensive and efficient use of straw and reduces environmental pollution caused by fiber board manufacturing through adopting straw burning and a wet method; moreover, the preparation method saves auxiliary materials and energy sources, thereby reducing cost; the wood-bamboo-straw fiber board does not have toxicity and public hazard, and is capable of being recycled and degradated to form beneficial biological cycle; and the intensity and decorative performance of both fiber board and composite board are improved, thereby enlarging application range.

Description

technical field [0001] The invention belongs to the technical field of wood and bamboo straw fiber boards and composite boards, in particular to the technical field of manufacturing biological fiber boards using bamboo, straw, reeds and the like. technical background [0002] There are three main methods of producing fiberboard: dry method, semi-dry method and wet method. In dry production, glue is added and heat-pressed to solidify into boards. The aldehyde glue used in the production process is harmful to the human body, and the cost of isocyanate is relatively high. The patent publication number is CN1069220, CN134866A, CN140374A, CN1089663C, CN1403255A, CN11280046, what relate to is the processing method of different wood, bamboo, straw fiber and plate, all adopts to add glue, replaces the glue that contains harmful substance formaldehyde by isocyanate, solidifies A dry method of production into boards. Semi-dry production, the fiber is easy to agglomerate and paving i...

AI Technical Summary

Problems solved by technology

Semi-dry production, the fiber is easy to agglomerate and paving industrial production is quite difficult, and it is difficult to control the moisture content to a constant value, and the product uniformity cannot be guaranteed, so it has not been used in industrial production so far

Wet production will be banned due to the high water consumption and environmental pollution in the fiber production process; and the middle and inner layer of the board produced by wet method is soft, the surface and surrounding hard layers are uneven, and the decorative effect is not good
