Abstract

The invention discloses bamboo and wood composited electrical laminated wood and relates to a process for producing the electrical laminated wood by adopting bamboos and fast-growing wood veneers. The process includes the steps 1), subjecting a thin bamboo veneer to water boiling treatment and soaking a poplar veneer in low-molecular-weight phenolic resin for strengthening treatment; 2), drying the treated bamboo veneer and the fast-growing wood veneer to be 6-8% in moisture content, applying polyvinyl butyral modified phenolic resin class (or polyvinyl butyral class resin/epoxy resin class) and drying the treated bamboo veneer and the fast-growing wood veneer to be 6-10% in moisture content prior to assembling; 3), pressing assembled bamboo veneer and fast-growing wood veneer to obtain an electrical laminated plate under the conditions that hot-press pressure ranges from 3.5MPa to 7.0MPa, time ranges from 1-2min/mm and temperature ranges from 110DEG C to 150DEG C. The bamboo and wood composite electrical laminated wood has the advantages that a medium-density bamboo and a low-density fast-growing wood veneer are composited, the bamboo can share part of compression stress, so that the problems that the electrical laminated wood produced by the low-density bamboo with an overlarge compression ratio is low in impact performance and poor in oil absorbency are solved. The bamboo and wood composited electrical laminated wood is good in dimensional stability, large in resistance, high in intensity and capable of being used for an electrical compression piece, an electrical ring, an insulating plate and the like.

Description

A kind of bamboo wood composite electrical lamination wood

Technical field

What the present invention relates to is a kind of method that adopts bamboo wood and fast growing wood veneer to manufacture electrical laminated wood, belongs to the wood-based plate manufacturing technology field in wood working industry.

Background technology

Electrical laminated wood is the transformer part of electric utility special use, is also unique construction insulation plywood required in high pressure components and parts.Obtain well behaved electrical laminated wood, need that oil-containing is few, wood acid is few, good mechanical property, even structure, source are abundant, low-cost seeds.As all adopting beech to produce electrical laminated wood ,Dan China, the countries such as France and the Soviet Union do not produce this timber abroad.China mainly adopts birch to substitute beech at present, and high-quality birch resource is also more and more rare.Low-density poplar etc. is substituted to the beech that hardness is large, and the lamination wood of making can't meet the demands completely in performance.Bamboo wood is close with beechy hardness, by bamboo wood and compound section structure and the similar product of beech electrical laminated wood made of low-density fast growing wood, has both solved China's lamination wood resource shortage, has also found the approach of the low-density material high value added utilizations such as poplar.The bamboo wood composite electrical lamination wood function admirable that this method produces, can meet the requirement of insulating materials, and its strength character is better than external beech lamination wood, and dimensional stability etc. also compare favourably with it.

Summary of the invention

What the present invention proposed is a kind of method that fast-growing low-density veneer is compound, gummed is pressed into electrical laminated wood of bamboo veneer and strengthening, the method makes the bamboo wood of intermediate density and the low-density material after strengthening realize good balance in dielectricity, mechanical strength and the porosity of insulating materials, can produce and meet electrical apparatus insulation material requirements, the lamination wood products of tool distinct Chinese characteristics.The method has solved material problem in short supply for electrical laminated wood, has improved the added value of the fast growing woods such as poplar, has developed a kind of Novel bamboo wood complex function structural material.

Technical solution of the present invention: adopt bamboo wood and fast-growing veneer to manufacture electrical laminated wood method, comprise following processing step:
