The use of material system grouting material, and corresponding advantageous effect could be obtained and do not learnt, therefore, the water-reducing agent tool in the application
There is uniqueness, in past development process, the preparation that applicant selected various types of water-reducing agents to be applied to the present invention is given birth to
In production, including commercially available common fatty family water-reducing agent, naphthalene water reducer, sulfamate based water reducer etc., but do not obtain
The effect of the invention finally wanted is obtained, the connected applications of even above-mentioned water-reducing agent also cannot achieve；Forced situation
Under, applicant has purchased according to each raw material composition feature of grouting material of the present invention by Jiangsu Subotexin Material Co., Ltd
The poly carboxylic acid series water reducer combination calcium lignosulfonate of production obtains the compound water-reducing agent in the application, and achieves meaning
Unimaginable effect.If the change of the composition of water-reducing agent or/and content in the present invention, can lead to beneficial effects of the present invention
It cannot realize well.
(2) swelling agent：The type of swelling agent is more, using most for UEA swelling agents, but its higher price, contain
The a variety of complicated expansion sources having are in the preparation system applied to grouting material of the present invention and unstable and suitable, can not obtain Shen
It asks someone expected technique effect；Then, applicant is having been surprisingly found that after many experiments, by calcium oxide swelling agent, alunite
Three kinds of swelling agent, sulphoaluminate expander compositions are according to mass ratio (2-4):(1-2):(1-3) merging collaboration utilizes can not only
It achieves the object of the present invention, improves the overall performance of grouting material, and at low cost, prepare reaction process and stablize, it is efficient, it obtains
Unexpected effect；If the change of the composition of swelling agent or/and content in the present invention, can cause the present invention it is beneficial
Effect cannot be realized well.
(3) hydrophober：Likewise, the selection of hydrophober composition of the present invention is not arbitrarily to obtain or there is originally,
It is also what applicant was obtained by many experiments, in development, applicant has been surprisingly found that ferric trichloride, calcium chloride, aluminum sulfate, SHP-
50 four kinds of organosilicon hydrophobic powder composition collaborative combinations use, and more suitable for the preparation system of grouting material of the present invention, use
Two kinds of compositions are stated according to mass ratio (1-3):(1-2):(1-2):(4-8), which merges, to be utilized, and each component material can be effectively changed
Surface characteristic, significantly improve water proofing property, stability, weatherability, frost resistance and the service life of grouting material, have it is non-aobvious and
Being clear to property；If the change of the composition of hydrophober or/and content in the present invention, can cause beneficial effects of the present invention cannot be very
Good realization.
Certainly, because of the requirement of the mentality of designing and goal of the invention of grouting material 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 grouting material of the present invention, in conjunction with the embodiment of the present invention it can be seen that, system of the invention
Preparation Method is designed using three steps, and raw material is added 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 5), this technique is adapted with the special proportioning of grouting material raw materials for production component of the present invention
, this technique is only used, just can guarantee the excellent specific property for the grouting material finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference 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 recorded in example is modified or equivalent replacement of some of the technical features.All essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
