NOVELTY - Partial silylated polyurethane prepared by reacting flexible long chain aliphatic hydrocarbon polyol and diisocyanate to synthesize terminal cyanate based polyurethane, and sealing end of the cyanate based polyurethane using silane coupling agent, is new.    USE - The partial silylated polyurethane is useful for single-component assembly adhesive seal type silicone glue, which is useful for a solar energy battery (claimed).    ADVANTAGE - The partial silylated polyurethane has a long aliphatic chain, excellent barrier for moisture vapor and improved weather resistance, prevents deep curing sealing glue adhesive layer from crack, absorbs moisture gas, improves the sealing glue storage ability and the adhesion strength to the base material, and promotes fast curing.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a single-component assembly adhesive seal type silicone glue for solar energy battery, comprising 100 parts by weight (pbw) of alpha - omega -di-hydroxy polydimethylsiloxane, 5-20 pbw of methyl silicone oil, 10-40 pbw of silylated polyurethane, 20-60 pbw of filler, 5-20 pbw of thixotropic agent, 2-10 pbw of pigment, 20-60 pbw of fire retardant, 5-20 pbw of crosslinking agent, 2-10 pbw of adhesion promoter and 1-2 pbw of catalyst; and    (2) preparing the single component assembly adhesive seal type silicone glue, comprising (1) adding alpha - omega -di-hydroxypolydimethylsiloxane, filler, flame retardant and partially crosslinking agent in a vacuum kneading machine at a temperature of 110-130 degrees C and a vacuum degree of -0.06 MPa to -0.099 MPa and dewatering and then mixing and cooling to obtain base material, and (2) adding methyl silicon oil, partially silylated polyurethane, thixotropic agent and cross-linking agent into a planetary stirring machine equipped with base material at room temperature of 80 degrees C and a vacuum degree of -0.06 MPa to -0.099 MPa and then uniformly stirring for 1-2 hours, and adding silane coupling agent and catalyst and then reacting for 0.5-1 hours.
