Description
Technical field
It is more particularly to a kind of using metakaolin and non-wood the present invention relates to a kind of geo-polymer base vegetable fibre board
Pulp fibres belong to building material technical field as the geo-polymer base vegetable fibre board of raw material.
Background technology
Cement fibrolite plate is because with waterproof and dampproof, fire-proof insulation, sound-insulating and heat-insulating, light weight is high-strength, construction is simple, safe nothing
Evil the features such as and obtained considerable degree of application, but fiber used mostly using mashing after wood pulp cellulose, its production technology
It is more complicated, so as to improve the energy consumption and production cost of cement fibrolite plate.Moreover, the production of cement will discharge a large amount of two
Carbonoxide, production process can also cause serious pollution to environment.In addition, non-wood pulp cellulose reinforced cement board is using process
In, its intensity and toughness have decline by a relatively large margin with the time, so not being used widely.
Geo-polymer is a kind of novel gelled material, compared to conventional portland cement, with intensity height, hardening
Hurry up, acid-alkali-corrosive-resisting the advantages of.Metakaolin, flyash, mineral waste etc. are mainly excited by using alkali-activator at present
In alumino-silicate prepare.
String is nature the abundantest natural polymer, and non-wood pulp cellulose mainly includes straw, rice husk, wheat
The agricultural crop straws such as straw, maize straw, bagasse, Cotton Stalk, wood chip, bamboo scraps or the stalk stem of other plants.
Because the performance of geo-polymer is better than cement, therefore it is combined with geo-polymer non-wood pulp cellulose production fiber
Plate, its performance is better than cement fibrolite plate, there is good application prospect, for the utilization of non-wood pulp cellulose, especially for agriculture
The utilization of forestry products residue has very strong realistic meaning.So, produce fiberboard with geo-polymer and non-wood pulp cellulose
It is boundless to reducing environmental pollution and its application prospect of the aspect of twice laid two.
Disclose a kind of ground polymers base fiberboard in the prior art, CN201310742307.4, it uses slag base geological
Polymer separates dried lumber fibre as fibrous material, again using polypropylene fibre, glass as matrix by the use of through defibrination
A kind of or both mixture in glass fiber is as reinforcing fiber, therefore its raw material and technics comparing are complicated.
The content of the invention
As the result of various extensive and careful research and experiment, it has been found by the inventor that using one
The geo-polymer of metakaolin and liquid the sodium silicate mixing of certainty ratio mixes the fibre that non-wood pulp cellulose makes as matrix
Dimension plate intensity can not only reach cement sawdust plate JC/T411-2007 standards, and higher than general cement sawdust on the market
Plate, and manufacture craft and raw material obtain simpler compared to the making of ordinary cement fiberboard.Found, completed based on this
The present invention.
It is an object of the invention to solve at least the above and/or defect there is provided a kind of raw material be only metakaolin,
Liquid sodium silicate and non-wood pulp cellulose and provide as the geo-polymer base vegetable fibre board of raw material and at least below will say
Bright advantage.
High it is a still further object of the present invention to provide a kind of intensity, hardening is fast, corrosion-resistant, and water resistance is good, water swelling
Rate is extremely low, and maintaining process condition is simple and convenient, the fiberboard harmless to the mankind, and it can replace the cement fibrolite plate used now
Apply in construction material, and better than current material.
A further object of the invention is to overcome cement base vegetable fibre board complex manufacturing, mashing can only be utilized fine
Dimension, the problem of production cost is high, improve the utilization rate of forest and agricultural biomass.
In order to realize that there is provided a kind of geo-polymer base string according to object of the present invention and further advantage

Properties of product：
Product properties all reach standard " cement sawdust plate JC/T411-2007 " requirement.
The main physico-mechanical performance such as table 1 below of product of the present invention after testing：
Table 1
The performance of comparative example is shown in Table 2
Table 2
From upper table 1, it can be seen that fine as a result of a certain proportion of liquid glass, metakaolin, wood chip in example
Dimension makes fiberboard, and its end properties is significantly higher than the standard of cement sawdust plate.For example, in example wood fiber composition ratio
It should control between 10~15, if it does, can then make composite structure relative loose, under obtained sheet material mechanical property
Drop；If fiber content is not enough, it can decline the humidification of fiber, also result in mechanical properties decrease.
Comparative example 1 is compared with example 1, and it is 18 parts to choose wood fiber content, except liquid glass accordingly changes in parameter
For 52 parts, every other parameter with it is identical in example 1, technical process is also identical.The performance of fibrous plate is not up to
To standard, fiber incorporation is primarily due to excessively, geo-polymer adhesive is very few, and causes incomplete mixing, so obtaining
Sheet material mechanical properties decrease.
Comparative example 2 is compared with example 4, and it is 37 parts to choose higher territory content, and liquid glass is accordingly changed into parameter
53 parts, every other parameter with it is identical in example 4, technical process is also identical.The performance of fibrous plate does not reach
Standard, the ratio for being primarily due to higher territory and liquid glass is relatively low, and first causes geo-polymer adhesive more dry, enters
And cause solid-liquid incomplete mixing, second make it that adhesive is difficult to fully soak fiber, and adhesive declines with fiber interface adhesion,
So obtained sheet material mechanical properties decrease.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With.It can be applied to various suitable the field of the invention completely., can be easily for those skilled in the art
Realize other modification.Therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the example with description.
