Description
Technical Field
The invention belongs to the technical field of wastewater and sludge treatment, and particularly relates to an ultra-early-strength and toughness quick repair material utilizing wastewater and sludge and a preparation method thereof.
Background
In recent years, the economy of China is rapidly developed, the consumption of concrete is increased rapidly, along with the prolonging of service time, the safety and the durability of a building structure are degraded year by year, a large number of concrete structures have diseases such as cracks, denudation and the like, and if measures are not taken in time, the harm is endless. At present, various repair materials such as common cement repair mortar, polymer repair mortar and the like are applied and have good effects. However, for the rapid repair projects such as airport runways and highways, the materials are difficult to meet the requirements of the projects (taking the repair projects of highways as an example, if the repair materials are adopted to seal the traffic for a long time, the maintenance time of part of the repair materials is at least 1 day or more, so that the development of the rapid repair materials with excellent performance is an important direction for ensuring the long-term stability of roadbed concrete structures.
The phosphate material is a rapid repairing material with good development prospect due to the advantages of fast hardening, early strength, good bonding property of new and old concrete, good wear resistance, low shrinkage, good volume compatibility, excellent durability and the like. However, the material has too fast setting time, short construction window period, high brittleness, low tensile strength and no construction effect without regulation. At present, borax is commonly used for adjusting the setting time of phosphate materials, but the borax can reduce the early strength and has no improvement effect on the flexibility. The water-based resin is a novel epoxy resin system taking water as a disperse phase instead of an organic solvent, and has the advantages of mutual solubility with water in any proportion, good flexibility, low toxicity, long service life, capability of being cured at normal temperature and the like. The inorganic-organic composite material system is formed by combining the two materials and fully utilizing the advantages of the two materials, and the quick-repair material is formed by quickly solidifying the wastewater and the sludge by utilizing the characteristic of quick hardening of the super-early-strength material. Meanwhile, the resin adhesive film is used for adjusting the flexibility and the curing time of the super-early-strength material, so that the super-early-strength and high-toughness quick-repair material which can utilize a large amount of waste and has high bending resistance, strong bonding, impact resistance and adjustable setting time is prepared, and the super-early-strength and high-toughness quick-repair material has wide application prospects in quick repair of highways and airport runways and rush repair and rush construction of military engineering.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived from the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
The present invention will be described in detail with reference to examples. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The ultra-early-stage high-toughness quick repair material utilizing the wastewater and the sludge has the advantages of high fracture resistance, strong bonding, impact resistance and adjustable setting time.
The quick repair material comprises the following components in parts by weight: 20-30 parts (such as 22 parts, 24 parts, 26 parts and 28 parts) of super early strength material, 1-10 parts (such as 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts and 9 parts) of coagulation regulating water-based resin, 40-70 parts (such as 45 parts, 50 parts, 55 parts, 60 parts, 65 parts and 70 parts) of sludge filler and 3-20 parts (such as 5 parts, 8 parts, 10 parts, 12 parts, 14 parts, 16 parts and 18 parts) of wastewater.
The quick-repair material is compounded by adopting the coagulation-regulating water-based resin and the super early strength material. Firstly, in the slurry, the hydration process of the acidic soluble phosphate and the alkaline exciting material in the ultra-early-strength material belongs to acid-base neutralization reaction, the heat release is large and rapid, and the gelation can be generated within a few minutes, so that the matrix strength is increased. Secondly, the super early strength material can quickly wrap the sludge filler, and quickly harden and reinforce harmful ions in the solidified sludge. And thirdly, the coagulation regulating water-based resin forms a flexible polymer three-dimensional net film-shaped structure in the gelled ultra-early strength material slurry, so that the pores are filled, and the flexibility of the quick repair material is improved. Finally, the coagulation regulating water-based resin is a hyperbranched water-based polymer, can stably exist in a cation environment and an anion environment, has high solubility and no flocculation, and can form an ion barrier in an ultra-early-strength material: functional groups such as amino groups, hydroxyl groups, ether chains and the like and hyperbranched side chains of the coagulation regulating water-based resin can adsorb anions and cations and hinder the proceeding of acid-base neutralization reaction, the functionality and the structure of the coagulation regulating water-based resin can be changed by adjusting the composition of bisphenol chain segments with bisphenol structures, and the higher the functionality and the longer the branched chains are, the stronger the retarding capacity is, thereby realizing the adjustment of the coagulation time of the super-early-strength material and solidifying harmful ions in waste water and sludge inside the material.
The reaction mechanism of the invention is as follows: the molecular chain of the coagulation regulating water-based resin contains polyether, hydroxyl, carboxylate, amino and ester group. The polyethers may be overlapped in solution to form a polymer web, the lone electron pair of oxygen atom and nitrogen atom in polyether, hydroxyl and amino is used for adsorbing peripheral cations, so that the rapid reaction of the cations is blocked; on one hand, the carboxylate increases the water solubility of the coagulation regulating water-based resin, on the other hand, the potassium ions have larger ionic radius and generate larger ionic bonds to peripheral anions, so that the quick reaction of the anions is blocked, and the reaction process of the acid-base neutralization reaction of the phosphate is effectively delayed. The ester group is hydrolyzed under strong alkaline environment to generate carboxyl. Carboxylate ions generate ionic bonds with magnesium ions, aluminum ions and calcium ions generated by phosphate, and different polymer molecular chains are crosslinked through metal cations, so that the beneficial combination of inorganic-organic materials is realized. The coagulation regulating water-based resin has very good bonding capability, and can be coated on a part to be repaired or poured into a crack with repair after being mixed with phosphate, so that the repair material can be firmly combined with an old matrix. After the coagulation regulating water-based resin is mixed with phosphate, the coagulation regulating water-based resin loses moisture, a film is formed and solidified to form a flexible polymer film, and the moisture is combined with phosphate particles to generate phosphate hydration, so that a hydration product with higher strength is formed. The polymer film forms a three-dimensional network structure in a solidified phosphate system, so that the flexibility of the material is greatly improved, and the repaired part has good bending resistance and impact resistance. The coagulation regulating water-based resin fills the pores of the phosphate-based material, so that the compactness of the material is greatly improved, the material is protected from external erosion, and the service time and the durability of the repair material are improved.
