Abstract
The present invention relates to the preparation method of the bulk asphalt plank of a kind of straw, it is characterized in that being undertaken by making step below: one, straw is carried out drying, spray wind except silt particle purification; Two, straw is carried out the chaotic formula process of machine mechanical agitation; Three, chaotic straw mechanical compress become the thickness needed for one and carry out infiltration pitch by the asphalt liquid of high temperature melting, molten asphalt liquid temp 200 DEG C; Four, the compressed straw slab infiltrating liquid bitumen is oozed asphaltic liquid unnecessary in plate by the warm oven of weighing apparatus (temperature 250 DEG C) and become bulk shape plate; Five, bulk shape plate is departed from oven and sclerosis of lowering the temperature becomes bulk shape straw asphalt plank.The preparation method of straw is bulk asphalt plank solves a large amount of straw problems, also provides better waterproof lightweight plate for industrial or agricultural material.
Description
Technical field
What the present invention relates to is a kind of method utilizing straw to make the multilayer composite sheet that raw material makes, and belongs to industrial technical field.
Background technology
China is grain-production big country, and wherein the plant development amount of paddy rice occupy the first place of various grain class output, and the plantation amount of visible paddy rice is huge.The plantation of paddy rice also creates the process problem of rice grass, a large amount of rice grass is used as the feed of livestock, but animal feeding-stuff just can consume the straw of small part, so remaining straw is just solved by combustion (of oil) insitu, burning straw not only wastes resource, also creates the pollution of environment.
A lot of composite enterprises also produces straw material using straw as raw material, is straw plate mostly.The making of general straw plate, is all that first straw is carried out chip becomes wood shavings, then utilizes alkali Soaking treatment, be made plate again after drying with resin stick mixing compacting; These method handling processes are too complicated, and the raw material of industry expended and time, too much the cost of investment was excessive, and this makes the limited in one's ability of process straw, and enterprise therefrom income is little, and the initiative of process straw is not high, can not solve the problem of a large amount of straw completely.
Summary of the invention
In order to the problem of straw can be solved, also in order to obvious economic interests can be obtained from using straw as raw material, we have invented a kind of method utilizing straw to make composite plate, the composite board bonding that this method makes closely, hardness and the straw intensity of toughness all than general high, be state-of-the-art straw processing and fabricating method.
The preparation method of a kind of straw is bulk asphalt plank taked technical scheme of dealing with problems is undertaken by making step below: one, straw is carried out drying, spray wind except silt particle purification; Two, straw is carried out the chaotic formula process of machine mechanical agitation; Three, chaotic straw mechanical compress become the thickness needed for one and carry out infiltration pitch by the asphalt liquid of high temperature melting, molten asphalt liquid temp 200 DEG C; Four, the compressed straw slab infiltrating liquid bitumen is oozed asphaltic liquid unnecessary in plate by the weighing apparatus temperature oven of temperature 250 DEG C and becomes bulk shape plate; Five, bulk shape plate is departed from oven and sclerosis of lowering the temperature becomes bulk shape straw asphalt plank.
Dry straw is a kind of plant being easy to be flooded profit, and volume after infiltrating and hardness change to some extent, and volume increases, hardness deliquescing, the restriction that this feature of straw makes straw be subject to as the raw material of plate material.If simply straw is carried out being bonded into plate, this compressed straw slab is once meet water and can infiltrate, and swelling, softening, rotten loose occurs subsequently, is exactly do not meet water to attack, also can there is the moisture in absorption air and change in straw, such compressed straw slab is applicable to using.Make compressed straw slab, the water proofing property process of straw raw material must be carried out, spraying is utilized to be stained with the preparation method that mixture is general industry raw material, but spraying is surfacer material just, and the major part of raw material still has water imbibition asphalt itself to have the feature of high temperature melting hardening at subcritical temerature, and water proofing property is fine, but asphalt is not suitable for making tabular, because the connection toughness of pitch is inadequate, and the ratio of volume and weight is excessive, too heaviness, easily rupture.We utilize water proofing property and low in price, the raw material abundance of asphalt, the method of science is utilized to be combined with straw, straw is made to become supporter and the toughness union body of bulk shape, straw can reach again the object of waterproof after infiltrating pitch, the straw asphalt plank of common combination reaches the optimum state of weight and volume, toughness, hardness.We have utilized the feature of asphalt high-temperature melting liquid to carry out to infiltrate and baking drip-dry, although the surperficial pitch of straw after baking drip-dry is little, but be to absorb the water proofing property straw of moisture.
The beneficial effect of the preparation method of a kind of straw is bulk asphalt plank is: the preparation method of a kind of straw is bulk asphalt plank utilizes the pitch of high temperature melting to infiltrate straw becomes waterproof straw raw material; Utilize straw as the supporter of bulkiness and union body, alleviate the weight of asphalt plank widely, preparation method is simple and quick, cost is few, and the straw asphalt plank hardness of making is high, toughness is strong, water proofing property is strong.
Detailed description of the invention
The preparation method of a kind of straw is bulk asphalt plank puts row into by making step is below real.
One, the straw adopted should be dry straw, and straw surface can not attach too much silt, and the existence impact compression step below of silt, the straw that water content is large also lacks hardness and can affect infiltration pitch below.
Two, straw is carried out chaotic formula process, neat straw does not have the connectivity of space-time, and what chaotic straw can produce space-time pulls connectivity, makes the composite plate of making show powerful hardness and toughness.
Three, by the straw mechanical compress of confusion become needed for thickness tabular and carry out infiltration asphaltic liquid by hard pitch liquid, impregnation process can successional conveyor type production line.Use the temperature 200 DEG C of molten asphalt.
Four, the compressed straw slab infiltrating pitch is oozed unnecessary bituminous liquids through oven, subsequently straw flaggy is cooled to rigid straw flaggy fast, the temperature of cooling is less than 10 degrees Celsius.
