Description
Technical Field
The invention relates to a plate and a preparation method thereof, in particular to a plant straw ecological plate and a preparation method thereof, and belongs to the technical field of novel building materials.
Background
The research on artificial boards made of crop straws starts late in China, and the artificial boards made of straws, wheat straws, bagasse and other raw materials are researched only in the 70 s of the 20 th century. In the 90 s, the novel adhesive is applied, and meanwhile, the artificial board manufacturing technology of wheat straws and rice straws is developed rapidly by taking the experience of foreign straw industry development as a reference.
At present, scientific research institutes such as Chinese academy of agricultural sciences, northeast forestry university, nanjing forestry university and the like develop a great deal of research on the aspect of straw artificial boards, and obtain some achievements, such as: the MDI oily isocyanate adhesive is adopted to prepare the straw artificial board.
However, the artificial straw-based boards are still particle boards in nature, and the number of production lines for industrially producing the artificial straw-based boards in China is very small and can be counted. The main reasons are as follows:
1. problems of the adhesive itself
The adhesive is the core for preparing the straw artificial board and directly influences the performance of the board. The preparation of the straw artificial board adopts the traditional wood particle board production process, uses urea-formaldehyde resin and melamine formaldehyde resin as adhesives, and is a production technology with the problem of formaldehyde emissions. In addition, waxy materials and siliceous materials on the surface of the crushed straw pieces and the straw with larger surface tension ratio and hydrophobic property can influence the bonding strength, thus causing poor bonding performance, higher water absorption, large thickness, water swelling and poor dimensional stability of the board. Therefore, MDI oily isocyanate adhesive is basically adopted by the current research institutions and production enterprises. However, the use of MDI oily isocyanate adhesives has some problems:
1. the MDI oily isocyanate adhesive is adopted, and because the MDI oily isocyanate adhesive has no initial viscosity, the integrity and the continuity of the paved plate blank after glue application are not good, the prepared plate is easy to collapse and delaminate in the transportation process, so that the transportation is difficult;
2. the MDI oily isocyanate adhesive is adopted, so that the paving plate blank has the problem of plate sticking in the hot pressing process, and the demoulding is difficult;
3. the MDI oily isocyanate adhesive does not contain formaldehyde, but contains volatile benzene aromatic hydrocarbon organic solvent. The fire-proof safety problem exists in the using, storing and transporting processes of the oily glue;
4. the dosage of the MDI oily isocyanate adhesive is basically 5 percent of the weight of the straws, the adhesive consumption is large, the cost is overhigh, and the MDI oily isocyanate adhesive has no competitive advantage compared with the manufacturing cost of wood artificial boards.
2. The treatment technology of the straw surface is imperfect
1. The growth environment of the straws determines that the straws contain a large amount of microbes such as bacteria, and the like, and before the plant straw board is prepared, the microbes such as the bacteria in the straws and the like must be killed, so that the plant straw board can be ensured not to mildew, rot or be damaged by worms in the long-term use process;
2. as the straw contains abundant waxy, siliceous and other hydrophobic substances, the bonding strength of the straw and the glue is poor, and the straw raw materials can be well fused with the glue only through emulsification, oxidation and hydrophobicity reduction, thereby ensuring the bonding strength.
3. Influencing the capacity of the plant
1. The mould is glued in the paving process, so that the demoulding is difficult;
2. the heat transfer performance of the crushed straw is poor, so that the hot pressing time is prolonged, and the production efficiency is not high.
At present, the straw artificial board in China is still in a learning stage, waiting for the technology to be mature and waiting for the production cost to be reduced. With the coming-out and vigorous support of the national policy of comprehensive utilization of the residual straws of crops, more scientific research units and enterprises can be attracted to research the artificial straw boards. With the advancement of science and technology and the maturity of the production technology of the straw artificial board, the straw artificial board industry can be greatly developed, and huge social benefits and economic values can be brought.

Step 2, preparing a special treating agent for plant straws
The raw materials and the dosage required for preparing the special treating agent for the plant straws are as follows:
58 to 62 portions of water, 2 to 3 portions of oxidant, 1.5 to 2 portions of wetting agent, 0.5 to 1 portion of emulsifier and 1 to 2 portions of bactericide.
Referring to fig. 2, the process flow for preparing the special treating agent for plant straws is as follows:
according to the formula dosage, adding water into a dispersion tank with a stirrer, firstly adding an oxidant under the stirring condition of the rotating speed of 200-300 rpm, dispersing for 10-15 min, then sequentially adding a wetting agent, an emulsifying agent and a bactericide, continuously dispersing for 15-20 min, and uniformly mixing to obtain the special treating agent for the plant straws (hereinafter referred to as special treating agent).
In the special treating agent:
(1) Oxidizing agent: potassium permanganate, sodium hydroxide, hydrogen peroxide or sodium hypochlorite can be selected;
(2) Wetting agent: fatty alcohol wetting agents may be selected, for example LWJ-678 produced by Jiangsu plum chemical industry;
(3) Emulsifier: OP-10 can be selected;
(4) And (3) bactericide: triazole bactericide can be selected, such as LWJ-688 produced by Jiangsu plum shift chemical industry.
The emulsifier in the special treating agent can convert wax on plant straws such as rice straws, wheat straws and the like into hydrophilic substances (wax emulsion), so that the problem of hydrophobicity on the surfaces of the straws is solved, and the bonding strength of the plant straws and the water-based adhesive can be greatly improved.
The oxidant in the special treating agent can react with the siliceous material in the plant straws to generate sodium silicate (water glass inorganic glue), and the reaction formula is as follows: siO 2 2 +2NaOH＝Na 2 SiO 3 +H 2 O, thereby eliminating the siliceous hydrophobicity and further improving the bonding strength of the plant straws and the water-based adhesive.

The bactericide in the special treating agent can thoroughly kill microbes such as bacteria in the crushed straw, so that the crushed straw has the effects of corrosion resistance, mildew resistance and moth resistance, and the storage life of the crushed straw and the service life of the plant straw ecological plate are greatly prolonged.
Therefore, the special treating agent provided by the invention can effectively treat waxy substances and siliceous substances on the plant straws and reduce the surface tension of the straws, so that the treated plant straws are suitable for various water-soluble adhesives.
TABLE 2 Special treatment agent (parts by weight)
| Group A | Group B | Group C | |
| Water (W) | 58 | 60 | 62 |
| Sodium hydroxide (oxidizing agent) | 2 | 2.5 | 3 |
| LWJ-678 (wetting agent) | 1.5 | 1.75 | 2 |
| OP-10 (emulsifier) | 0.77 | 0.84 | 1 |
| LWJ-688 (Bactericide) | 1 | 1.5 | 2 |
The comparison of the bonding strength of the plant straw before and after being treated by the special treating agent is shown in the table 3.
TABLE 3 comparison of bonding strength before and after treatment of plant stalks with a specific treatment agent (formula B)
As can be seen from the above table, the bonding strength of the plant straw treated by the special treating agent is greatly improved. This is because: the special treating agent contains an emulsifier and an oxidant, wherein the emulsifier can react with wax in the plant straws to generate a hydrophilic substance (to obtain wax emulsion) to eliminate the hydrophobicity of the wax, and the oxidant can react with silica in the plant straws to generate sodium silicate (to obtain water glass inorganic glue) to eliminate the hydrophobicity of the silica, so that the special treating agent can obviously improve the bonding strength of the plant straws and the water-based adhesive.
Step 3, preparing straw crushed aggregates
The water content of the common straws is 10-15% when the straws are just withdrawn from the field, and the water content is 8-10% when the straws are piled for several days after harvesting. The straws which are piled for several days after being harvested or just recovered from the field are crushed, so that the utilization rate is low, the glue consumption is large, the cost is high, and most importantly, the strength and the toughness of the prepared board are low.
Research experiments show that: when the water content of the straws is 20-22%, the crushed materials are not too much when the straws are crushed, and the optimal grading standard of the artificial straw board can be achieved.
Just, the special plant straw treating agent with the straw mass of about 10% is added when the straw is crushed, so that the grading standard of the artificial straw board is achieved, waxy materials and siliceous materials on the straw are treated, and the surface tension of the straw is reduced.
Referring to fig. 3, the process flow for preparing the straw scraps is as follows:
feeding plant straws (such as rice straws, corn straws, cotton straws, sorghum straws, soybean straws and sesame straws) into a special speed-regulating pulverizer for straws, spraying a special plant straw treating agent accounting for 10% of the weight of the plant straws by a high-pressure gun under the condition of low-speed stirring, uniformly mixing the special plant straw treating agent and the plant straws, pulverizing at a high speed, grading and sorting after the crushed straws meet the grading requirement required by a plant straw ecological plate, and drying at a high temperature of 180-210 ℃ in a rotary dryer for 3-4 min to obtain crushed straws with the water content of 4-5%.
Step 4, hot pressing plate or cold pressing plate
The required raw materials and the dosage are the same regardless of hot pressing plates or cold pressing plates, and the specific steps are as follows:
580-620 parts of plant crushed aggregates, 36-42 parts of reinforcing agent and 120-130 parts of special adhesive.
In the present invention, the plant pieces comprise: crushed straw, bagasse and wood residue, wherein the crushed straw comprises: crushed rice straw, crushed corn straw, crushed cotton straw, crushed sorghum straw, crushed soybean straw and crushed sesame straw, wherein the wood residue comprises: wood residue obtained by crushing waste wooden furniture and wood. When the board is pressed, one plant crushed material can be used independently, two or more plant crushed materials can be mixed together for use, and the performance of the prepared plant straw ecological board is not obviously influenced.
In the present invention, the grading requirements of the plant chaff required for the pressboard are: 25% of the length of 10mm, 35% of the length of 20mm, 24% of the length of 30mm and 16% of the length of 40 mm.
In the invention, the reinforcing agent can improve the strength and impact resistance of the plant straw ecological plate and can also improve the waterproof performance of the plant straw ecological plate, and Portland cement, portland white cement, anhydrous gypsum, semi-hydrated gypsum, kaolin, mica powder, argil, calcium carbonate or silica powder can be selected, and the Portland cement, the Portland white cement, the anhydrous gypsum or the semi-hydrated gypsum is preferred.
The production process of the plant straw ecological board provided by the invention is basically the same as the production process of the artificial shaving board, and the production equipment of the artificial shaving board can be adopted without technical improvement.
Referring to fig. 4, the process flow of hot pressing the plate is specifically as follows:
(1) According to the formula, the plant crushed aggregates and the reinforcing agent are sequentially added into a mixing machine and are dry-mixed for 3-5 min, so that the plant crushed aggregates and the reinforcing agent are uniformly mixed;
(2) Spraying the special adhesive (glue mixing) into a mixer in a high-pressure spraying mode under the stirring condition of the rotating speed of 200-300 rpm, and stirring for 10-15 min until the surface of the crushed plant material is uniformly adhered with the special adhesive;
(3) Hot pressing the plate: adopt the spreading machine to carry out the blank and mat formation, control system board thickness ratio of paving is the finished plate: billet =1:6, hot pressing at 180 ℃ under 3.2MPa for 9min (the thickness of the plate prepared under the hot pressing condition is 12 mm);
(4) And others: and (5) cooling the plate, sequentially cutting edges, filling sand and veneering, and warehousing after the plate is qualified in inspection.
Because the special adhesive provided by the invention has long opening time and good initial adhesion, when the plant straw ecological plate is prepared, a heat-eliminating pressing plate process can be adopted, a cold pressing plate process is adopted, and no matter the hot pressing plate process or the cold pressing plate process is adopted, the performance of the prepared plant straw ecological plate is not obviously influenced.
Referring to fig. 5, the process flow of cold pressing the plate is specifically as follows:
(1) According to the formula, the plant crushed aggregates and the reinforcing agent are sequentially added into a mixing machine and are dry-mixed for 3-5 min, so that the plant crushed aggregates and the reinforcing agent are uniformly mixed;
(2) Spraying the special adhesive (glue mixing) into a mixer in a high-pressure spraying mode under the stirring condition of the rotating speed of 200-300 rpm, and stirring for 10-15 min until the surface of the plant crushed material is uniformly adhered with the special adhesive;
(3) Cold pressing a plate: after the special adhesive for the plant crushed aggregates and the plant straw ecological plates is mixed, the mixture is firstly dried in a workshop for 1-5 h (glue drying), then a spreading machine is adopted to spread the blanks, and the plate manufacturing and spreading thickness ratio is controlled to be finished plates: billet =1:6, cold pressing under the pressure of 5-6 Mpa for 30-40 min (the thickness of the plate prepared under the condition of the cold pressing is 12 mm);
(4) And others: and after the plate is dried, sequentially carrying out edge cutting, sand filling and veneering, and warehousing after the plate is qualified through inspection.
The cold-pressed board saves energy and has lower cost than the hot-pressed board because the board-making temperature required by the cold-pressed board is lower than that required by the hot-pressed board.
