The application discloses a preparation method of an interface treatment agent for a steel structure, and comprises the following steps: adding graphene powder and boron nitride powder into a mixed solution composed of ethanol and water, performing ultrasonic treatment, then centrifuging the mixed solution, collecting supernatant, drying the supernatant, and obtaining graphene nanosheet / boron nitride nanosheet composite material; mixing and stirring polydimethylsiloxane, dibutyltin dilaurate and the graphene nanosheet / boron nitride nanosheet composite material, adding polyacrylate emulsion, and performing stirring treatment to obtain modified polyacrylate emulsion; mixing cement, redispersible latex powder, river sand, defoaming agent, triethanolamine and hydroxyethyl methyl cellulose as dry material components; and taking the modified polyacrylate emulsion as a liquid component. The interface treatment agent can not only effectively improve the interface performance between the steel structure and mortar, but also improve the corrosion resistance and weather resistance of the surface of the steel structure.

The disclosed technology generally relates to methods of forming foamed and non-foamed aqueous rubbers for use in automotive applications and which are configured to provide vibration and noise damping. In one aspect, a method of forming an elastomer comprises forming a latex solution and then curing the latex solution. Forming the latex solution comprises forming a medium by mixing water and ethylene glycol monobutyl ether (glycol ether EB) and then adding to the medium a rheology modifier, a dispersing agent, a wetting agent, a filler material, and a latex suspension. Water makes up 50-90 wt. % of the latex solution.

The invention discloses a damp-heat-resistant anti-cracking indoor non-expansive fireproof coating and a preparation method thereof, and belongs to the technical field of building fireproof materials. The preparation method comprises the following steps: firstly, mixing deionized water, hydroxypropyl methyl cellulose ether and a polycarboxylate water reducing agent to prepare a base solution; adding layered magnesium zinc silicate, calcium aluminum borosilicate nano-hybrid ceramic powder, kaolin, sericite powder, glass powder, titanium dioxide and modified hollow ceramic microbeads into the base solution, uniformly stirring, and adding styrene-acrylate copolymer emulsion and redispersible latex powder to obtain a mixture; and finally, adding the organic silicon defoaming agent and the polyurethane flatting agent into the mixture, and stirring to obtain the coating. Through the synergistic effect of the two specific inorganic modified compounds and optimization of a filler system, the obtained coating has excellent heat and humidity resistance and cracking resistance in a normal state, can form a compact and stable non-expansion heat-insulation protection layer at a high temperature of a fire disaster, and has significantly improved comprehensive performance.

An aqueous coating composition that includes a monoalcohol and a diol or polyol, and a compound with urea functionality is disclosed. The aqueous coating composition has less than 250 grams per liter VOC, is capable of being quality application to a variety of substrates at temperatures below freezing (32ºF), being stored for more than 2 weeks below freezing without bulk freezing, and being applied by a variety of usual application techniques (brush, roller, sprayer) at temperatures below freezing. The additives may be added individual during manufacturing of the coating composition or added together to a coating composition as a low temperature additive package.

This application relates to the field of composite membrane processing technology, and more specifically, to a composite diaphragm preparation process and the resulting product, comprising the following preparation steps: S1, applying a primer coating to the kraft paper surface of the composite membrane to form a primer coating layer, thereby obtaining a kraft paper composite layer; S2, printing a surface coating onto the substrate using a gravure printing method to form a discontinuous surface coating layer, thereby obtaining a composite substrate layer; S3, bonding the kraft paper composite layer to the composite substrate layer using a wet lamination process, and then bonding the primer coating layer and the surface coating layer together using a pressure roller to obtain the composite diaphragm. This process results in a smooth and flat surface on the kraft paper, making it less prone to adhering putty powder, thus ensuring stable sealing of the putty powder packaging bag, preventing moisture and air from entering, and extending the shelf life of the putty powder.
