The invention relates to bamboo plywood and a process method thereof, which belongs to the production technology field of building or furniture sheet materials. The invention is characterized in that the bamboo plywood comprises the following raw material components by the weight ratio as follows: 30 to 50 percent of bamboo powder, 5 to 20 percent of light magnesium oxide, 5 to 20 percent of magnesium hydroxide, 20 to 40 percent of epoxy adhesive, and 3 to 6 percent of silane coupling agent. The process method comprises the following processing steps: natural bamboo is crushed and grinded into 20 to 100 order powder; the light magnesium oxide and magnesium hydroxide are grinded into 500 to 800 order powder for standby use; the raw materials are weighted according to the weigh ratio of all raw material components; the powdered bamboo powder, the light magnesium oxide, and the magnesium hydration are mixed evenly in a container; the emulsive and paste-like epoxy adhesive and silane coupling agent are placed into the container to heat, and the heating temperature is 50 to 60 DEG C; all raw materials are placed into the container to be mixed, stirred and uniformly poured into a prefabricated mold, and are compacted using an oil press to form a plate blank.
Description
Technical field:
The present invention relates to a kind of bamboo composite plate and manufacturing technique method thereof, it belongs to building or Furniture panel production technical field.
Background technology:
Existing synthetic plate all is a wooden boards usually, and this class wooden boards need consume a large amount of timber as raw material, and cost compares higher.In order to solve the problem that timber resources lacks, had in the prior art and utilized the raw materials for production of bamboo as sheet material, but the production major part of existing bamboo board all is to utilize bamboo clappers to process, the influence that is subjected to bamboo self of this machining sheet is bigger, the template that does not have big change bamboo only be bamboo is simply spliced or to superpose, so the purposes of its product has also been received very big restriction, as building board, its intensity can not reach the standard that needs.Providing step as its bamboo of Chinese patent the 93109273.6th " bamboo board manufacturing method and products thereof " is with well-thought-out plan debranching, defoliation and be cut into suitable length in addition, the step in blocks of planing is to become laminar along the planing of fiber alignment direction bamboo, dry vulcanisation step is bamboo chip to be sent into to dry in the drying machine vulcanized so that bamboo chip insect protected, anticorrosion again, mixing the glue step is bamboo chip to be sent into to mix in the glue machine mix with glue, and molded and shaped step is that the raw material behind the mixed glue is sent in the suitable mould to make various product.This processing method complex process, its product that processes is owing to be subjected to the restriction of bamboo chip structure itself, and the outward appearance of its product is more special, and its applicability and use face are also smaller.
Summary of the invention:
The object of the present invention is to provide a kind of intensity height, the outward appearance applicability is wide, and production technology is simple, and the bamboo composite plate of environmental protection and manufacturing technique method thereof.
The purpose of this utility model is achieved in that
A kind of bamboo composite plate is characterized in that it comprises following materials of weight proportions composition:
