More Information
Summary:The invention provides a strongly hydrophobic two-component sealant and a preparation method thereof, the strongly hydrophobic two-component sealant comprises a component A and a component B. The component A comprises the following raw materials by mass: 55-65 parts of modified polyaspartic acid resin, 35-40 parts of a first filler, 1-2 parts of a pigment, and 0.5-1.5 parts of a plasticizer; the component B is prepared from the following raw materials in parts by mass: 45 to 55 parts of composite isocyanate, 25 to 38 parts of second filler, 15 to 20 parts of butylene adipate and 0.5 to 1.5 parts of toughening agent. The double-component seam beautifying agent provided by the invention has relatively strong hydrophobic and moisture-proof performance and is suitable for being applied to long-term humid places, the weather resistance, yellowing resistance, wear resistance and corrosion resistance of the seam beautifying agent are enhanced by introducing the composite isocyanate curing agent and the filler, the s
