Antibacterial is carried out using gap filler of " GB/T 21866-2008 " the antibiotic property measuring method to above-described embodiment and comparative example
Performance detection, testing result are as follows:
In embodiment gap filler sample anti-microbial property >=99.10%；Antibacterium endurance quality is >=96.30%；
And gap filler sample anti-microbial property is only >=78.50% in comparative example；Antibacterium endurance quality is only >=71.20%；
In conclusion gap filler of the invention is worthy of careful study in raw materials for production selection, the collaboration that assembles between raw material is made
With make finished product gap filler obtained mechanical strength, hydrophobicity, wearability, frost resistance, antibiotic property, in terms of upper promotion
Significantly, 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: for common coupling agent in gap filler preparation have silane coupling agent, titanate coupling agent,
Aluminate coupling agent etc., it is real in order to preferably reach the purpose is to be merged for reacting organic polymer and inorganic filler
Existing above-mentioned purpose, technical team find after many experiments, and KH-550 is belonged in silane series coupling agent and is being applied to material of the invention
Effect is best in Material system, but the effect generated is still not enough felt quite pleased, and therefore, applicant attempts to merge other types of coupling
Ingredient advanced optimizes, finally unexpected to obtain anti-settling Aluminate ASA, rare-earth coupling agent, silane coupling agent KH-
550 3 kinds of ingredients 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 citric acid gypsum powder, calcium titanium mine tailing, red halloysite in adhesion promotion raw material
Equal ingredients are filled into material system, what the physical property and protection materials interface for improving filler were damaged from environmental stress
Ability improves the overall performance of finished product gap filler.If compounding the ingredient of coupling agent or/and the change of content in the present invention,
Will lead to beneficial effects of the present invention cannot realize well.
(2) 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 P750 type organosilicon moisture repellent, three second of isobutyl group
Oxysilane collaborative combination uses, and is particularly suitable for the preparation of gap filler of the invention, can depth of penetration enter cement base or
In mineral substrate surface, and hydrophobic layer can be formed in substrate, inhibit the infiltration of hydrone, and then significantly improve and fill out
The hydrophobicity of agent is stitched, and said effect is not achieved in the hydrophober of other types；If in the present invention compound hydrophober at
Point 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 gap filler 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 gap filler 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 and is blended (such as comparative example 13), this technique is the special proportion phase with gap filler raw materials for production component of the present invention
It adapts to, only uses this technique, just can guarantee that the smooth sequential of gap filler raw material reaction system carries out, ensure last preparation
The excellent characteristics of gap filler out.
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.
