The application discloses a high-strength, large-pore-volume phosphorus-containing binder, characterized in that the binder comprises a glue, a curing agent and a modifier; the glue comprises a phosphorus-containing compound and an aluminum-containing compound; the curing agent comprises a gamma-aluminum oxide precursor, an acid and an alkylammonium salt, and the modifier is a metal chelate; wherein the colloidal solubility index of the gamma-aluminum oxide precursor is less than or equal to 50%; and the modifier is reacted with the glue in a high-shear dispersion emulsifier. The phosphorus-containing binder provided by the application, in combination with a conventional method, can obtain a catalytic cracking catalyst which, on the basis of high molecular sieve content and large pore volume, still has high wear resistance.

The application provides a pre-spraying anti-sticking waterproof construction method, which comprises the following steps: spraying pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating on the surface of a base layer to be constructed; naturally drying after the construction is completed; uniformly spreading fine sand on the surface of the pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating to form a fine sand layer; pouring a subsequent concrete structure after binding steel bars, so that the fine sand layer is naturally integrated with the concrete and becomes a part of the poured concrete, thereby preventing the steel bars from being bonded with the pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating and from damaging the pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating, preventing the waterproof layer from being damaged by the steel bars during the construction process, and effectively protecting the waterproof layer; the fine sand layer can also serve as a protective layer, reducing the surface temperature and surface aging degree of the waterproof layer formed by the pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating under long-time direct sunlight, and thereby improving the anti-sticking performance of the pre-spraying anti-sticking sprayed rapid-setting rubber asphalt waterproof coating.

The utility model relates to the technical field of road reconstruction construction, in particular to an old pavement reconstruction edge widening structure, an old pavement is sequentially composed of an original roadbed, an original cushion layer, an original base layer and an original surface layer from bottom to top, the old pavement comprises a V-shaped groove, the V-shaped groove is formed in one side of the old pavement, and the side, corresponding to the V-shaped groove, of the old pavement is of a step structure; the backfill base material is arranged in the V-shaped groove, and the top of the backfill base material is flush with the top of the original roadbed; the new base layer is paved on the top of the new cushion layer and is flush with the top of the original base layer; and the new surface layer is paved at the top of the new base layer and is flush with the top of the original surface layer. The V-shaped groove is used for burying backfill base materials, the problem of waste treatment is solved, meanwhile, soil taken out when the V-shaped groove is formed is used for forming a new roadbed, and therefore stability and consistency of structural materials of a broadened part are guaranteed.

The application provides a fire-retardant adhesive, a fire-retardant double-sided adhesive tape for bonding porous rough materials and a preparation method of the fire-retardant double-sided adhesive tape. The bonding layer of the fire-retardant double-sided adhesive tape is made of the fire-retardant adhesive. The fire-retardant adhesive comprises 100 parts of solvent type acrylate glue, 20-40 parts of a fire retardant, 2-6 parts of tackifying resin, 0.4-1 part of a curing crosslinking agent and 20-30 parts of a second solvent in terms of weight. The fire retardant comprises a liquid fire retardant and a solid fire retardant. The liquid fire retardant is an organic phosphorus-nitrogen ionic liquid fire retardant. The solid fire retardant is ammonium polyphosphate. The specific type of fire retardant is compounded with the solvent type acrylate glue, and the bonding performance of the adhesive tape is not affected. The synergistic fire-retardant mechanism of the condensed phase and the gas phase is realized, the adhesive layer has excellent fire-retardant performance, and the adhesive tape can be applied to bonding scenes such as automobile interior part assembly and electronic product cushion fixing.
