Abstract
The invention discloses a high-permeation chemical grouting material and a preparation method thereof. The high-permeation chemical grouting material is formed by stirring, by weight, 65-80 parts of methyl methacrylate, 20-35 parts of butyl methacrylate, 1.5-2.5 parts of dibenzoyl peroxide, 1-2 parts of deoxidant and 2-5 parts of accelerant. According to the high-permeation chemical grouting material, the methyl methacrylate serves as the main agent of the grouting material, and the viscosity of methyl methacrylate is low and smaller than that of water, so that quite good mobility is achieved, the high-permeation chemical grouting material can be easily permeated into a small crack or even a micro crack which cannot be seen by naked eyes, meanwhile a membrane is formed on the surface of the crack, a quite good surface sealing function is achieved, an excellent mechanical property is further achieved, bonding strength is high, and the high-permeation chemical grouting material is particularly suitable for repairing road cracks. The prepared grouting material has low initial viscosity, proper gelation time and good mechanical performance index.
Description
Technical field
The present invention relates to a kind of grouting material, be specifically related to a kind of Thief zone type chemical grouting material and preparation method thereof。
Background technology
Cement concrete pavement is different from other concrete structure, and it is exposed banded structure in the Nature, and the repeat function of wheel load is not only stood on road surface, and also suffers the periodically variable impact of atmospheric temperature。Therefore, the material embedding pavement crack should possess good physical property, chemical property, mechanical property and durability。As desirable road surface early crack patching material, it is desirable to hardening can be condensed as soon as possible or solidify, being open to traffic as early as possible, reduce road operation obstacle and economic loss。In order to avoid interface to occur, secondary ftractures。Therefore, the contraction of patching material should be reduced so that it is there is the less contraction of more former pavement concrete as far as possible, even produce microdilatancy performance。As pavement crack repair material, to stand the impact shock effect of vehicle dynamic load equally。It is therefore desirable to patching material should have certain deformability。From environmental angle, advocate and use " green material ", the theory of " people-oriented " is applied in developing material, application process。Under the premise meeting mechanical property, superior performance, low price, workability, durability, reduce material unit price, it is simple to the repairing material for concrete pavement of popularization as far as possible。
Summary of the invention
Present invention aim at, it is provided that a kind of environmental protection, economical, permeability is strong, it is simple to the chemical grouting material of operation, and the technical solution adopted in the present invention is:
A kind of Thief zone type chemical grouting material, it is characterised in that reacted by weight percentage by following components and form:
Methyl methacrylate 65-80 part
Butyl methacrylate 20-35 part
Dibenzoyl peroxide 1.5-2.5 part
Oxygen scavenger 1-2 part
Accelerator 2-5 part。
Further, described oxygen scavenger is N-N-dimethylaniline。
Further, described accelerator is to toluenesulfinic acid。
The step preparing Thief zone type chemical grouting material is as follows:
(1) first methyl methacrylate and butyl methacrylate are weighed in the three of condensing tube
In mouth flask；
(2) with heating in water bath to 80 DEG C, it is slowly introducing nitrogen, adds dibenzoyl peroxide, oxygen scavenger (N-N-dimethylaniline), be stirred for uniformly；
(3) after solid constituent is completely dissolved, being eventually adding accelerator (to toluenesulfinic acid), keep reaction temperature at 85-90 DEG C, synthesize while stirring, reaction 2-2.5h can lower the temperature and obtain chemical grouting material。
The present invention provides the benefit that relative to prior art: the Thief zone type chemical grouting material of the present invention, adopting methyl methacrylate is the host of grouting material, the architectural feature of methacrylate resin adhesive is that molecular end has methacrylate based group, its degree of functionality is high, cured product has three-dimensional cross-linked structure, so thermostability, resistance to water, media-resistant and resistance to weathering can be all relatively good。Additionally methyl methacrylate viscosity is low, viscosity less than water, therefore there is good mobility, gap or even invisible micro-cracks can be easily infiltrated into, form thin film simultaneously on surface, play good surface-closed effect, and also there is the mechanical property of excellence, adhesion strength is high, is particularly suited for the repairing of facial cleft seam。The grouting material that the present invention prepares, has relatively low initial viscosity, suitable gelling time and good mechanical performance index。
