Description
Technical field
The invention belongs to environment-friendly materials fields, and in particular to a kind of corn stalk fiber brick.
Background technology
The whole world is there are about 1,000,000,000 tons of maize straws, and there are about 2.5 hundred million t in China.Cycle efficiently utilizes stalk resource, realization stalk
Recycling and industrialization are to solve the basic plan that stalk is discarded and burned.About 40,000,000,000 m of China's existed building2, the year two thousand twenty whole nation
Floor space will be 68,600,000,000 m2.If stalk can be introduced to construction industry, realize double industry mergingization development, can both alleviate building
Resource that industry faces, the energy, environmental pressure, and the new way of agricultural economy can be expanded.
Corn stalk fiber is used as material, it is multiple that corrugating medium, packaging material, expanded material, stalk-cement can be produced
Condensation material, grass-plastic composite material, vegetation composite material, thermal insulation material.
Using calcium hydroxide as raw material, calcium hydroxide slurry, cement mortar, tung oil mortar, glutinous rice mortar, extensive use can be prepared
In architectural engineering.
How the two to be organically combined to the construction material for obtaining more environmental protection and economy, become this field and urgently solve
One of certainly the technical issues of.
Invention content
For many shortcomings of the existing technology, the present invention provides a kind of corn stalk fiber brick, the fibers
Brick is prepared using corn stalk fiber as raw material, calcium hydroxide slurry are adhesive in the method being cold-pressed, the light weight wall obtained
Body block material is a kind of novel environment-friendly building materials, which is similar to light wood, has good sense of touch, warming sense, dress
Decorations property, is suitble to be widely popularized and apply.
The specific technical solution of the present invention is：
A kind of corn stalk fiber brick, composition of raw materials are in parts by weight：
327~417 parts of corn stalk fiber, 1744~1924 parts of calcium hydroxide slurry.
The wherein described corn stalk fiber, mesh number for 10~100 mesh and more than；Moisture content is 10.05~10.76%；
Density is 0.0999~0.1042g/cm3；
The calcium hydroxide is calcium hydroxide slurry, and moisture content is 47.36~52.20%, density for 1.015~
1.115g/cm3
Compared with prior art, disclosed article is compared particularly before inventor, and maximum difference of the invention is profit
By the use of maize straw as raw material, compared with wheat straw before, the two has dramatically different：It is embodied in：
Wheat straw is annual gramineae plant.Wheat is made of stalk, leaf, leaf sheath, cob etc., and root system is stem fibrous root
System, stalk height is up to more than 1m, blade lanceolar；Mass ratio is 52.4% between ajoint of a culm, leaf 29.1%, and knot is
9.2%, cob 9.3%；
It is formed from cell, the fibrocyte of wheat straw accounts for about 62.1%, and parenchyma cell accounts for 29.4%, and conduit accounts for 4.8%, table
Chrotoplast accounts for 2.3%, separately there is 1.4% other heteroproteose cells；
Wheat straw main chemical compositions are cellulose, hemicellulose and lignin, wheat straw internode content of cellulose highest, wheat straw
Hemi-cellulose content is equivalent to the peak of broad-leaved wood in hemicellulose, and the content of ashes in the submember of wheat straw is far above wood
Material, and more than 95% be silica in ash content, the hot-water extraction object content of wheat straw is also higher, about 10%-23%, wherein fruit
Colloid is only 10% or so, most of for oligosaccharide such as starch.1% sodium hydroxide the extractives content of wheat straw is about higher than timber
1 times, illustrate that the content of low molecular weight carbohydrate in wheat straw is higher；
Wheat straw autologous density is smaller, and the averag density of internode is 0.313g/cm3(moisture content W=8.9%), close to root
Internode wall it is thicker, density 0.316g/cm3, the averag density of section is 0.341g/cm3
(W=8.9%), the averag density for saving sheath is 0.257g/cm3(W=8.9%).In terms of the cross section of internode, epidermis
Locate solid, averag density 0.383g/cm3, middle level 0.307g/cm3, internal layer 0.298g/cm3。
And the maize straw of the present invention, belong to grass family, Agrostidoideae, Zea, October is the harvest time, main
It is made of root, stem and leaf.The proportion very little that root is accounted for leaf, so studying both at home and abroad the stem of maize straw more.Maize straw
Stem be mainly made of three crust, the stalks of rice, wheat, etc. and knot parts, the chemical composition of each section is different, causes nature difference notable.
Crust is mainly made of cellulose, hemicellulose and lignin, and content is higher, and fiber is long, good toughness, so crust
It is mechanical strength The cream of the crop in maize straw, therefore papermaking and the good raw material of building materials can be used as；The stalks of rice, wheat, etc. accounts for corn stalk
75% or so of stalk total volume, in containing abundant crude fat, crude protein and glucide, light weight and mechanical strength is low,
It is unsuitable for papermaking use.But it is with certain elasticity, its Filamentous vascular structure is a series of but also its molding is secured
Structural advantages cause its padded coaming competition in occupy advantage.It can be seen that maize straw mechanical strength of the present invention is bright
It is aobvious to be higher than wheat straw, and since chemical composition has apparent difference, it is caused to have larger difference two in purposes and function
Person, which cannot be equal, regards it, it is even more impossible to accomplish use substituted for one another, is found after detection, the raw material of the present invention is prepared into reality
Body brick is used as partition wall.Brick compression strength is 0.53-1.02MPa.And the wheat stalk obtained in the first document of inventor is built
The intensity of block is almost nil, does not have weight-bearing function completely, it is seen that the two makes a marked difference.
After according to above-mentioned principle proportioning, raw material is mixed, purpose brick can be obtained by being prepared by the way of cold pressing,
The specific steps are：The mold for filling stirring material is put on cold press, installs pressure head, setting pressure is 10Mpa, presses cold press
Pressurizing button, after pressure head is completely forced into mold, time 10min, temperature is room temperature.
Using the corn stalk fiber brick that the above method obtains, the material is similar to lightweight for a kind of novel environment-friendly building materials
Timber has good sense of touch, warming sense, dicoration, is suitble to be widely popularized and apply.
