Abstract
The invention provides a method for manufacturing an environment-friendly fiber board by utilizing corn stalks and bamboo wood, and belongs to the field of processing of artificial boards. The use amount proportion of the corn stalks to the bamboo wood is 1/10-2/5, and the environment-friendly fiber board is formed by carrying out tissue culture and hot pressing on an esterified fiber in the rift grain direction. The method makes full use of the autumn corn stalks in our country and avoids urea resin and phenolic resin which are high in formaldehyde content, and the manufactured fiber board has high environmental value. Fiber boards of different strengths can be obtained by adjusting the proportion of corn fibers to bamboo fibers, and therefore the application fields of the fiber board are widened.
Description
Technical field
The present invention relates to a kind of production method utilizing maize straw and bamboo wood to manufacture environment protecting fiber board, this technology belongs to Wood-based Panel Production manufacture field.
Background technology
China's timber resources enriches, and occupancy volume per person is low.Along with China protects a forest implementing of policy, and the forest reserves reduced gradually, the available timber resources of China is short gradually.For meeting the growing demand of people, actively find wood substitute material extremely urgent.Corn is one of China three generalized grain kind, output accounts for 1/4th of national total output of grain, maize sown area is extensive, mainly concentrate on northeast, North China, southwest and northwest,, every autumn harvest season, there is large quantities of maize straws the Liao Dynasty in the north, Ji, black, Inner Mongol, Shanxi, Ji, Shandong, provinces and regions, Henan 8 or is discarded in roadside, or burned landfill, cause a large amount of environmental problems and the wasting of resources.Make full use of abundant maize straw resource and there is important economic worth and social effect.
The quality testing system of China to fiberboard is not yet perfect, producer often uses urea-formaldehyde resin adhesive or phenolic resin adhesive in the process of producd fibers plate, the product content of formaldehyde produced is often higher, and higher concentration of formaldehyde meeting serious harm people's is healthy.A lot of country has formulated corresponding conservation regulation and regulation in the world for this reason, and the formaldehyde safe level of regulation room, workplace is 0.1PPM.
Summary of the invention
The present invention proposes a kind of production method utilizing maize straw and bamboo wood producd fibers plate, the method takes full advantage of the maize straw resource of China's abundant in autumn, reduces the content of formaldehyde in fiberboard simultaneously.This fiberboard dimensional stability is high, intensity good, can be applied in indoor furniture and decoration field.
For achieving the above object, present invention employs following technical scheme: maize straw is removed blade by a, bamboo removes branch and blade; Maize straw and bamboo roll by b respectively, are isolated into single fiber; C zein fiber is (1-4) with the weight ratio of bamboo fibre: 10 mix, and does not upset the distribution of its fiber; D esterification: fiber is added a certain amount of aceticanhydride, the weight ratio of aceticanhydride and composite fibre is (2-3): 5, use sulphur acid as catalyst, reaction 40-60 minute, temperature 100 DEG C-120 DEG C, carry out acetic acid esterified, sulfuric acid dosage and composite fibre weight ratio are (2-5): 100, heating removing acetic acid; F is by the single fiber after esterification, and group training on fibre length direction, under 85-100MPa pressure, individual hour of hot pressing 5-7, can obtain environment protecting fiber board.
Detailed description of the invention
Maize straw is removed blade by 1, and bamboo removes branch and blade; Two Plants are put into roller by 2 respectively to roll, and the single fiber be isolated is separated; Zein fiber mixes according to weight ratio 3:10 with bamboo fibre by 3, keeps its fiber distribution mode; The fiber mixed is put into aceticanhydride by 4, uses sulphur acid as catalyst, aceticanhydride: sulfuric acid: the weight ratio of fiber is 50:3:100, and react 50 minutes, temperature remains on 110 DEG C; 5 heat away acetic acid; 6 by the composite fibre after esterification, group training on fibre length direction, hot pressing 6 hours under 95MPa pressure.
Take full advantage of idle maize straw resource with the fiberboard that the method makes, and content of formaldehyde is 0, can be applied in indoor furniture and field of constructional ornament.In addition, the ratio of adjusting corn fiber and bamboo fibre content can be passed through, produce the fiberboard of varying strength.Bamboo fibre content is higher, and the intensity of fiberboard is larger, can be applied to building structure aspect; Improve the content of zein fiber, the softness of fiberboard can be increased, the aspects such as padded coaming, sound insulation and noise reduction material and packaging material can be widely used in.
Claims (4)
