Description
Technical field
The present invention relates to a kind of road gap-grouting glue material, especially relate to the road gap-grouting glue material after a kind of modification, belong to chemical material technical field.
Background technology
The gap-grouting material that industry is traditional has pitch class, neoprene, the encapsulants such as poly-sulphur and polyurethanes, cannot meet under cryogenic conditions and use for a long time, and current existing organic silicon rubber class gap-grouting material, although can reach our needed performance, but in order to reach excellent tensile elongation, often adopt segment longer, the base glue that viscosity is larger, in order to increase the intensity of material and to reduce costs, often add more filler, cause the viscosity of gap-grouting material larger, process more complicated, execution conditions harshness.
Thixotropy refers to that liquid can become the state that mobility is larger from thickness state under shear action, and after shear action is cancelled, liquid returns to the performance of original thickness state again. Thixotropic quality of silicon rubber has determined white glue production, the stability of storage and the difficulty or ease of glue-applying technique. Can promote in Process of Applying Glue, to there is good mobility, be conducive to improve the even coating of base joint grouting glue, reduce applying glue difficulty, improve coating quality. Therefore, the thixotropic property of raising base joint grouting glue is the important method that improves bin stability and reduce applying glue difficulty, raising coating quality.
Wollastonite is a kind of anorthic system, conventionally in the form of sheets, radial or fibrous silicate crystal. Color is white in color, and is sometimes with light gray, pale red tone, has glassy lustre. Be widely used in the composite industry such as papermaking, pottery, cement and plastic, rubber. Acicular wollastonite (part commodity are also referred to as wollastonite fibre) is the one of wollastonite powder filler, is widely used in field of compound material. In industry at present, use the more needle-like filler (its draw ratio is between 8:1 to 15:1) for common draw ratio, be difficult to the thixotropic property of polymer solution or emulsion to exert an influence. High length-diameter ratio acicular wollastonite is the product occurring on market in recent years, and its higher draw ratio has good strengthening action to silicon rubber, thereby is applied in rubber industry as Silicone rubber reinforcing filler.
In current domestic most base joint grouting glues (sealant material) patent, all relate to the formula Design under organosilicon sealing material pointing normal temperature condition, processing technology and construction method, but can keep winter resistance and the storage stability of material in severe cold area, the consideration that the problem of construction simplification etc. is not focused on.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of thixotropy is good, stable storing, the easy modification road gap-filling cement of construction material.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Filling-modified pair of component road gap-grouting glue of a kind of high length-diameter ratio acicular wollastonite, is characterized in that, comprise A component and B component, described B component and the mass ratio of A component are (2～5): 100, and all in parts by weight,
A component comprises:
