Table 7
By upper table 7, it can be concluded that, anti-fire door core board of the invention is worthy of careful study in raw materials for production selection, between raw material
Assembling synergistic effect makes anti-fire door core board obtained in the side such as mechanical strength, fire resistance, waterproofness, heat-resisting frost resistance, oil resistivity
It is promoted significantly on face, overall performance is more excellent, and application is more preferable, and service life is more secure.
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: common coupling agent is mostly silane series coupling agent in anti-fire door core board preparation, for that will have
Machine macromolecule and inorganic filler reaction fusion, technical team find that the U.S. silane series coupling agent Zhong Shu joins carbon after many experiments
The model silane coupling A -151 of company's production effect in being applied to material system of the invention is best, but not enough
Satisfied, therefore, applicant attempts the other ingredients of addition and merges with it using and then come reach final purpose of the invention, anticipates finally
It is obtained outside by anti-settling Aluminate ASA, rare-earth coupling agent, three kinds of ingredients of silane coupling A -151 and with obtained compounding
Coupling agent, it is very prominent that this kind compounds the beneficial effect that coupling agent obtains, considerably beyond other types and the coupling agent assembled, it
Can efficiently the ingredients such as Chinese fan palm leaf fibre, niobium yttrium mine tailing, pyrophyllite powder are filled into material system in adhesion promotion raw material, change
The ability that the physical property and protection materials interface for being apt to above-mentioned filler are damaged from environmental stress, improves finished door coreboard
Overall performance.If compounding the ingredient of coupling agent or/and the change of content in the present invention, it will lead to beneficial effects of the present invention
It cannot realize well.
(2) foaming agent is compounded: it is well known that foaming agent use condition and object are harsher, in different material systems
In, foam performance is more unstable, therefore, existing inorganic foaming agent, protein foaming agent, synthetic surfactant class foaming agent
Deng be in being applied to preparation method of the invention it is unworkable, will lead to the problem of plate foaming effect difference；Applicant is examining
Under characteristic and the density case of considering material system, dexterously by 3.5% sodium hydrate aqueous solution, white hair infusion WBA-T, jade
Rice seitan powder, soybean protein glue, wooden sodium sulfonate, silicone resin polyethers lotion (10-14) in mass ratio: (2-4): (4-6): (1-
3): (0.5-1.5): the compounding foaming agent that (1.5-2.5) proportion is blended can admirably achieve the flat of preparation system of the present invention
Weighing apparatus, and then realize efficient, the fine foaming of plate, ensure anti-fire door core board processability；If compounding foaming agent in the present invention
Ingredient or/and content change, will lead to beneficial effects of the present invention cannot realize well.
(3) compound hydrophober: the selection of hydrophober composition of the present invention is not arbitrarily to obtain or there is originally,
It is that applicant is obtained by many experiments, in development, applicant has been surprisingly found that IE-6683 water-proof emulsion, three ethoxy of isobutyl group
The collaborative combination use of base silane, ferric trichloride, is extremely suitable for anti-fire door core board substrate of the invention, and can be in substrate
Hydrophobic layer is formed, the infiltration of hydrone is inhibited, and then preferably improves the hydrophobicity of plate；If compounding hydrophober in the present invention
Ingredient or/and content change, 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 anti-fire door core board of the present invention, remaining group sorting of the present invention
It selects and content selection is obviously also non-obvious, those skilled in the art combine the prior art that can readily occur in absolutely not.
This has further embodiment in the preparation method of anti-fire door core board of the present invention, in conjunction with the embodiment of the present invention it can be seen that, this
Raw material is added using three step designs in the preparation method of invention by several times in batches, and step is simple and orderly, rather than uses existing skill
Conventional being added at one time of art is blended (such as comparative example 10), and this technique is and anti-fire door core board raw materials for production component of the present invention
Special proportion be adapted, only use this technique, just can guarantee the smooth sequential of anti-fire door core board raw material reaction system
It carries out, ensures the excellent characteristics for the anti-fire door core board 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.
