The specific embodiment
Embodiment 1:
See also Figure 1 and Figure 2, finish figure for the flow chart of steps and the finished product of method for producing environmental-friendly wallboard provided by the present invention, its step includes:
Step 1: plant fiber powder, magnesia powder, talcum powder and rigid sour calcium powder are stirred by mixer, promptly form raw material; This plant fiber powder can be according to user demand pulverize, graininess or intercept shape; The material of this plant fiber powder can be cornstalk; This plant fiber powder can be cornstalk to be mixed roughly the same the time with other plant, as: plant classes such as wheat straw, paddy, coconut husk, cotton bar, weeds branch, culled wood bits; The percentage by weight of each ingredients constitute batch mixing of this raw material is: plant fiber powder 25~35%, magnesia powder and talcum powder 10~15%, rigid sour calcium powder 10~15%.
Step 2: treat that raw material stirs a period of time and is added into curing agent again, stirred through mixer once more, promptly form batch mixing; This curing agent is made up of inorganic coagulation material, organic compound and modifier; The percentage by weight of each ingredients constitute batch mixing of this curing agent is: inorganic coagulation material 15~20%, organic compound 10~13% and modifier 0.003~2%;
Step 3: batch mixing is poured into to the making sheet mould, and laid glass fiber mesh on batch mixing;
Step 4; By vibrations facility vibrations making sheet mould, cause more consolidation of batch mixing combination again, repave a little batch mixing on wallboard,, flatten at wallboard again, make its gel coagulation forming to fill up weak point;
Step 5: after treating that wallboard flattens, make wallboard natural air drying under indoor natural temperature, last, carry out demoulding program again with the taking-up wallboard, and wallboard is placed outdoor natural air drying once more, promptly finish the finished product 10 (as shown in Figure 2) of wallboard.
Wherein, wallboard is greater than 15 ℃ of natural air dryings about 3~12 hours in indoor temperature.
Embodiment 2:
See also Fig. 3, Fig. 4 and shown in Figure 5, finish figure for flow chart of steps and the finished product of another embodiment of this method for producing environmental-friendly wallboard, its step includes:
Step 1: plant fiber powder, magnesia powder, talcum powder and rigid sour calcium powder are stirred by mixer, promptly form raw material; This plant fiber powder can be according to user demand pulverize, graininess or intercept shape; The material of this plant fiber powder can be cornstalk; This plant fiber powder can be cornstalk to be mixed roughly the same the time with other plant, as: plant classes such as wheat straw, paddy, coconut husk, cotton bar, weeds branch, culled wood bits; The percentage by weight of each ingredients constitute batch mixing of this raw material is: plant fiber powder 25~35%, magnesia powder and talcum powder 10~15%, rigid sour calcium powder 10~15%;
Step 2: treat that raw material is added into curing agent again through stirring a period of time, stirred through mixer once more, promptly form batch mixing; This curing agent is made up of inorganic coagulation material, organic compound and modifier; The percentage by weight of each ingredients constitute batch mixing of this curing agent is: inorganic coagulation material 15~20%, organic compound 10~13% and modifier 0.003~2%;
Step 3: batch mixing is poured into to the making sheet mould, and laid glass fiber mesh on batch mixing;
Step 4; Again by vibrations facility vibrations making sheet mould, cause more consolidation of batch mixing combination, again more than one at least Partition wall boards internal mold is arranged on the batch mixing, and make the Partition wall boards internal mold be subjected to batch mixing fully to fill up, again glass fiber mesh is layed on the batch mixing, and spreads a little batch mixing on wallboard, to fill up weak point, flatten at wallboard again, make its gel coagulation forming; This Partition wall boards internal mold can be short side tubbiness or hollow round barrel shape in one;
Step 5: after treating that wallboard flattens, make wallboard natural air drying under indoor natural temperature, last, carry out demoulding program again with the taking-up wallboard, and wallboard is placed outdoor natural air drying once more, promptly finish the finished product 20 (as Fig. 4, shown in Figure 5) of a Partition wall boards.
Wherein, wallboard about 1~2 hour, is about to the Partition wall boards internal mold and takes out greater than 15 ℃ of natural air dryings in indoor temperature behind the gel coagulation forming.
Wherein, wallboard in indoor temperature greater than 15 ℃ of natural air dryings about 3~12 hours.
Wherein, when wallboard is done in indoor natural wind, when being lower than 15 ℃, make indoor temperature be warming up to more than 15 ℃ with hot gas as if indoor temperature.
Like this, promptly finish wallboard finished product of the present invention by above steps.
Because plant fiber powder based on crops, its content can be that like product is incomparable, after with plant fiber powder and the stirring of talcum powder uniform particles up to 35%, it coagulate to make a concerted effort strong, and (heat transfer coefficient is 2.32w/ (m can to possess the heat-insulation and heat-preservation of string simultaneously
2Advantages such as .k)), sound insulation (sound insulation value is 38db (a)), acid and alkali-resistance and radiationless pollution; And product of the present invention through the vibrations consolidation, flatten, be provided with step process such as glass fiber mesh, because the stretch-proof of string links function, make wallboard have effects such as high strength, anti-aging, antidetonation, stretch-proof, the present invention is listed below each test value result:
1. heat transfer coefficient 2.32 (w/m
2* k);
2. air-borne sound oise insulation factor 38dB;
3. moisture content 3%;
4. the fire prevention timeliness is more than 114 minutes (test of area, continent);
5. drying shrinkage value 0.5mm/m;
6. compression strength 4.0Mpa;
7. bending resistance failing load (plate deadweight multiple) is 4.6 times;
8. coefficient of softing 0.83;
9. hanging force 1000kg (24 hours frees from flaw);
10. impact resistance (5 times impact no through crack);
11. surface density 60.7kg/cm
2
12. meeting U.S. FDA food regulation, environmental protection can contact with food;
This shows, the wallboard that utilizes the present invention to finish, regardless of the finished product of finishing with wallboard or Partition wall boards, its weight is less than 35kg/m
2, be 1/7 of reinforcement component weight, significantly reduce the basic load-bearing of building, simultaneously, can significantly save effect such as 30% of foundation cost.
Above-listed detailed description is at the specifying of possible embodiments of the present invention, and this embodiment is not in order to limiting claim of the present invention, does not allly break away from equivalence of the present invention and implements or change, all should be contained in the claim of this case.
