The invention relates to the technical field of asphalt preparation, in particular to SBS / waste rubber powder composite modified asphalt and a preparation method thereof.The preparation method comprises the following preparation steps that S1, matrix asphalt and modified SBS are mixed and dissolved, and after shear development, a first-order mixed and dissolved substance is obtained; s2, adding modified rubber powder into the first-order miscible substance, and shearing and developing to obtain a second-order miscible substance; and S3, adding a stabilizer into the second-order miscible substance, and stirring and cross-linking to obtain the SBS / waste rubber powder composite modified asphalt. Through the synergistic effect of the modified SBS and the modified rubber powder, the viscosity of a system is reduced, the network structure strength of the SBS is maintained, a stable physical-chemical composite network is formed in the asphalt, phase separation is not prone to occurring in the heat storage process, the low-temperature ductility of the asphalt is improved, and the composite modified asphalt still keeps good flexibility in a low-temperature environment.

The invention relates to the field of anticorrosive paint, in particular to hyperbranched epoxy resin anticorrosive paint and a preparation method thereof. The coating is a two-component system, wherein a component A comprises an epoxy resin main body, 5-20 parts of a hydroxyl-terminated hyperbranched polyester modifier, a flaky filler, an anti-rust pigment, a reactive diluent and an auxiliary agent; the algebra of the hyperbranched polyester is G2-G4, and the hyperbranched polyester is prepared by melt polycondensation of trimethylolpropane and 2, 2-dimethylolpropionic acid; and the component B is a polyamide curing agent. The preparation method comprises the following steps: synthesizing hyperbranched polyester; pre-mixing the component A with epoxy resin, grinding and dispersing with filler and auxiliaries, and mixing paint to obtain a component A; mixing a curing agent with a coupling agent to obtain a component B; by utilizing the unique structure of the hyperbranched polyester, the epoxy coating is obviously toughened on the premise of not losing the hardness, the viscosity of the system is reduced, the constructability and the filler dispersity are improved, and finally the high-performance coating with impact resistance, strong adhesion and long-acting corrosion resistance is obtained.

This invention provides an absorbent for capturing carbon dioxide and a method for capturing carbon dioxide. By volume percentage, the absorbent comprises 20-60% glycine salt aqueous solution, 10-50% triethylene glycol monomethyl ether, 5-10% ethylene glycol, and the balance being water. This absorbent combines the advantages of glycine salt systems, such as low volatility, non-toxicity, safety, and better antioxidant degradation resistance, while avoiding the risk of solid precipitates forming after absorption by the glycine salt system, which could cause pipeline blockage.

The invention discloses anacardol modified polymerized MDI, which is prepared by the following method: carrying out hydrolysis reaction on anacardol glycidyl ether under an acidic condition to generate anacardol derived diol; and then reacting the cardanol-derived diol with the polymerized MDI at the temperature of 75-80 DEG C. The invention further discloses polyurethane floor paint based on cardanol modified polymerized MDI. The polyurethane floor paint is prepared from a component A and a component B, the component A is hydroxyl-containing resin or polyol, and the component B comprises cardanol modified polymerized MDI. The floor paint is prepared by reacting cardanol modified polymerized MDI with a hydroxyl-containing substance, a cardanol side chain introduced by the cardanol modified polymerized MDI plays roles of'molecular diluent 'and'space shielding', and the reaction speed and system viscosity of the floor paint are reduced, so that the floor paint has excellent construction performance and low bubble characteristic. The invention further discloses a preparation method of the polyurethane floor paint based on the cardanol modified polymerized MDI.

This application relates to the field of insecticide technology, specifically to a slow-release insecticidal suspension and its preparation method. The insecticidal suspension comprises the following raw materials in weight percentages: 8%–30% thiamethoxam, 7%–20% lambda-cyhalothrin, 0.1%–2% slow-release agent, 3%–10% emulsifier, 1%–5% dispersant, 1%–5% silica, 1%–5% activated clay, 0.1%–2% xanthan gum, and water to 100%. The dispersant includes a first dispersant and a second dispersant; the first dispersant is sodium lignosulfonate, and the second dispersant is one or both of sodium maleic acid-acrylic acid copolymer and sodium naphthalenesulfonic acid formaldehyde polymer. The slow-release insecticidal suspension of this invention avoids Austronesian maturation, has good dispersibility, can be processed into high-concentration formulations, has low packaging costs, good stability, long shelf life, high suspension rate, and good slow-release effect.
