Performance detection
Plasterboard test specimen made from above-described embodiment 1-5 and comparative example 1-12 is taken to carry out following performance detection, detection knot
Fruit is reported in Table 7 below that (the plasterboard test specimen of embodiment 1-5 indicates that the plasterboard test specimen of comparative example 1-12 adopts using #1-#5 in table
It is indicated with &1-&12)
1. sample dimensions: 30*40*9.5mm；
2. the detection of transverse breakage load: test specimen being placed in two parallel lower branch roller (centers of plate Intensity of Breaking Tester
Away from 350mm), plasterboard is face-up.In span center, it is further applied load by loading roller (being parallel to lower branch roller) to plate,
Loading speed is 4.2N/s ± 0.8i/s, until test specimen is broken, using the load maximum value of application as the transverse breakage of the test specimen
Load is accurate to 1N.As a result the arithmetic mean of instantaneous value of the transverse breakage load of five test specimens is taken.
3. the detection of water absorption rate: test specimen electronic scale is weighed test specimen quality (Gx1), it is (25 ± 5) DEG C subsequently into temperature
Water in, test specimen holder suspension is not close to bottom of gullet, and test specimen is taken out after the 2h that soaks away from water surface 30mm in test specimen upper surface,
Surface of test piece adhesive water is sucked with half wet towel, weighs test specimen quality (Gx2), each test specimen is recorded before immersion and after immersion
Quality, and by formula (1) calculate water absorption rate Wx。
Wx=[(Gx1-Gx2)/Gx2] × 100%------------------ (1)
In formula:
Wx--- test specimen water absorption rate, %；
Gx1--- quality before test specimen soaks, unit are gram (g)；
Gx2--- quality after test specimen immersion, unit are gram (g)；
The average value of five test specimen water absorption rates is calculated, and records maximum value therein, is accurate to 0.5%.
4. the detection for amount of deflection of making moist: taking three pieces of test specimens to be dried to constant, then every piece of test specimen faces down, make two seamed edges
Be parallel to abutment roller, respectively hang be placed on dampness amount of deflection analyzer three test stands support on, support center away from for test specimen it is long
Degree subtracts 20mm, using dedicated measuring head, measures the sag in test specimen centre on each test stand.Then by test stand
It is steadily put into constant temperature thermostatic curing case, is placed under the conditions of temperature is (32 ± 2) DEG C, relative air humidity is (90 ± 3) %
48h steadily takes out test stand from curing box, the sag after measuring each test specimen centre dampness.Record test specimen dampness
The value added of front and back sag, as the dampness amount of deflection of test specimen.
The average value of five test specimen dampness amounts of deflection is calculated, and records maximum value therein, is accurate to 0.0lmm.
5. the detection of fire resistance: by the measurement of method as defined in GB 8624-2012.
6. the detection of latent heat of phase change value: being measured using differential scanning calorimetry.
7. inhaling wave rate: by the measurement of method as defined in GB 5239-2004.
Table 7
By upper table 7 it is found that plasterboard of the invention shows on mechanical strength, hydrophobicity, fire resistance, accumulation of heat wave absorbtion
Excellent, plasterboard performance boost compared to the prior art is significant, and application performance is good, practical reliable, has good promotion price
Value.
In conjunction with the beneficial effect of the present invention, applicant illustrates constituent part and preparation method of the invention as follows:
(1) compound coupling agent: during the preparation process, common coupling agent is mostly silane series coupling agent to existing plasterboard,
For being obtained organic polymer and inorganic filler reaction fusion through research, the isobutyl group in many silane series coupling agent products
The effect that triethoxysilane generates in being applied to the present invention is best, can not only promote material compatible, moreover it is possible to improve plate
Waterproofness, but the effect that applicant generates the single composition coupling agent of this kind is not felt quite pleased also, and therefore, and it is other to attempt addition
The coupling agent of ingredient merges with it using and then come reach the purpose of the present invention, and on this basis, applicant finally surprisingly obtains
According to mass ratio be (3-5) by isobutyl triethoxy silane, rare-earth coupling agent: (1-3) merges obtained compounding coupling agent,
This kind compounds the beneficial effect that coupling agent obtains and protrudes very much, can be efficient considerably beyond other types and the coupling agent assembled
Organic-inorganic ingredient is compatible in ground adhesion promotion raw material, improves the ability that plate interface is damaged from environmental stress.If
The ingredient of coupling agent or/and the change of content are compounded in the present invention, will lead to beneficial effects of the present invention cannot be real well
It is existing.
(2) compound rubber powder: rubber powder in building materials application mainly plays a part of bond, can improve material cohesive force,
Resistance to stress intensity, impermeability and construction flexibility；Common redispersible latex powder can not adapt to of the invention on the market
Material system, it is difficult to which the technical effect that the present invention of acquirement wants, then applicant is having been surprisingly found that after many experiments, will
The 5044N type latex powder of Wa Ke company production cooperates with to utilize with the swf05 type latex powder of three-dimensional company's production can be realized this hair
Bright purpose can significantly improve the overall performance of finished product plate, achieve the object of the present invention；If composite glue powder in the present invention
Composition or/and content change, will lead to beneficial effects of the present invention cannot realize well.
(3) compound air entraining agent: use condition and object of the air entraining agent in building materials are harsher, common inorganic/chemistry
For type air entraining agent list composition using being difficult to meet the needs of gypsum board panels of the present invention are to foaming, applicant is considering gypsum raw material
Under the characteristic and density case of system, dexterously by three kinds of corn gluten meal, α-sodium olefin sulfonate, hydrogen peroxide ingredients according to quality
Than for (6-8): (1-2): (3-5) carries out rational proportion, is finally reached the balance of preparation system, obtains good foaming effect
Fruit improves the performance of the thermal isolation and heat storage of product；If compounding the ingredient of air entraining agent or/and the change of content in the present invention,
Will lead to beneficial effects of the present invention cannot realize well.
Certainly, because of the requirement of the mentality of designing and goal of the invention of plasterboard of the present invention, remaining of the invention component selection and
Content selection is obviously also non-obvious, and those skilled in the art combine the prior art that can readily occur in absolutely not.This
Have further embodiment in the preparation method of plasterboard of the present invention, in conjunction with the embodiment of the present invention it can be seen that, system of the invention
Raw material is added using three step designs in Preparation Method by several times in batches, and step is simple and orderly, rather than conventional using the prior art
It is added at one time (such as comparative example 11), this technique is adapted with the special proportion of gypsum board manufacture raw material components of the present invention
, this technique is only used, could ensure the plasterboard excellent characteristics finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
