2results about How to "Good synergistic effect" patented technology

The application discloses a water-based rust conversion agent, which comprises the following raw materials in parts by weight: water-based styrene-acrylic emulsion 45-55 parts, nano-lotus clay coordination compound liquid modifier 15-20 parts, nano-barium sulfate coordination agent 5-9 parts, rust conversion agent 3-6 parts, defoaming agent 3-5 parts and film-forming aid 1-3 parts. The application has strong wetting and penetrating functions, can penetrate to the bottom of a rust layer to passivate or convert the rust layer, and is suitable for the following fields: steel bar corrosion prevention in a construction site, steel structure workshop manufacturing and maintenance, color steel tile manufacturing and corrosion prevention renovation, shipbuilding, large equipment manufacturing and maintenance, storage tank manufacturing and the like.

This invention describes a modified silicate-polyurethane two-component grouting reinforcement material, comprising component A and component B, which are mixed in a 1:1 volume ratio before use. Component A, by mass percentage, consists of the following components: water glass: 94%; glycerol: 1%; glyceryl ester compounds: 1%; silane coupling agent: 1%; water: 3%. Component B, by mass percentage, consists of the following components: polymethylene polyphenyl polyisocyanate PM-200: 65%; dibutyl phthalate (DBP): 35%. This invention utilizes the synergistic effect of glyceryl ester compounds and silane coupling agents. The glyceryl ester compounds reduce the interfacial tension between the aqueous and oil phases and promote the uniform dispersion of the silane coupling agent. The silane coupling agent forms a chemical bridge between the inorganic and organic phases, enabling the originally incompatible aqueous and oily agents to form a homogeneous and compatible system. The resulting solidified body has a compressive strength of 24.6 MPa and a bond strength of 3.8 MPa, making it suitable for seepage prevention and sealing in underground engineering and for surrounding rock reinforcement.
