The invention discloses an environmentally-friendly damping rubber sheet, which comprises a damping rubber layer comprising 10-20% by mass of a petroleum resin, 3-20% by mass of a butyl rubber, 3-20%by mass of polyisobutene, 2-10% by mass of a deodorant and the balance of a filler, wherein an isolation layer is arranged on an isolation layer. The preparation method comprises: (1) weighing the materials; (2) synthesizing; (3) calendering; (4) blanking; and (5) coating with an isolation layer, and loading into a packaging box. According to the present invention, the butyl rubber with high damping performance is used as the matrix, and the adhesive property and the strength of the rubber sheet are improved by adopting the viscous resin and the filler, such that the high damping performance of the whole damping rubber sheet in a relatively wide range is ensured while the high viscosity of the damping rubber sheet is ensured; and the selected materials are odorless at a normal temperature,and have weak odor at a temperature of 60-80 DEG C, such that the odor problem of the product can be solved by adding 2-5% of the chelating deodorant.

The invention discloses a deodorization garbage can and a using method thereof. The deodorization garbage can is characterized by comprising an upper can cover, a can body and a base, wherein the can body is divided into three layers; the upper layer is a garbage storage layer; the middle layer is a drawer type filler layer; the lower layer is a garbage percolate collecting layer; the three layers are separated by laminate boards; the laminate boards are net-shaped structure or are provided with a plurality of through holes; a composite filter used for deodorizing and adsorbing garbage percolate is filled in the drawer type filler layer; and a transparent observation window used for observing height of the garbage percolate in the garbage percolate collecting layer and a water discharge faucet used for discharging the garbage percolate in the garbage percolate collecting layer are arranged on the barrel wall of the garbage percolate collecting layer. According to the deodorization garbage can, the problems that a current garbage can is simple in function and odor and the garbage percolate are generated in high-temperature weather are solved; and in a using process, the garbage percolate collected and the composite filter material which adsorbs the garbage percolate further can be directly used as raw materials of a community forestry fertilizer or an organic fertilizer for being further utilized.

The invention provides a method for in-situ control of hydrogen sulfide odor in sediments. The sediments are allowed to contact with indissolvable or insoluble particle oxidizing agents to remove hydrogen sulfide in the sediments through an in-situ oxidation and reduction process, and the oxidizing agent is recycled by in-situ regeneration. The method is further used for control of hydrogen sulfide odor of the sediments in rainwater pipelines, rivers or sewage pipelines.

The invention discloses a composite spraying material and frame for downhole quick leaking stoppage and filling and an implementing method thereof, and belongs to the composite spraying material and the sealing frame, and the implementing method thereof. A set reasonable proportion of phenolic foam, polyurethane foam and urea formaldehyde foam is selected, a base material of the spraying materialis synthesized, a proper flame retardant is added, and the properties of the base material are increased; an antistatic material, a catalyst, a curing agent, a surfactant, a foaming agent and other materials are added, and the flame-retardant and anti-static composite macromolecular spraying material is formed through specific technological process. Fiber-Kevlar is selected as a raw material to form the sealing frame and is used as a carrier of the spraying material, the structure deformation is flexible, and a whole for quick sealing and leaking stoppage is formed jointly. Through different embodiments, the composite spraying material is verified to have the characteristics of light mass, fast forming, strong sealing and good fire prevention and leaking stoppage effects, can effectively prevent downhole air leakage and harmful gas gushing and ensures the safety of workers.
