The invention discloses an application of an organic silicone modified high-molecular compound as a seed coating film former. The organic silicone modified high-molecular compound has a molecular structure fragment described in a general formula (I): definitions of all groups in the formula are described in the instruction. The film former with a reticular structure is formed by the crosslinking reaction of the molecular structure fragment in the general formula (1) and a soluble film forming material containing hydroxyl, amino, carboxyl, alkoxy and amide groups. The film former has good water resistance and water permeability, and can simultaneously meet the different requirements of a dry field and a paddy field. A seed coating agent prepared by adopting the film forming material meets the requirements on both viscosity and strength, has significant improvement on expulsion rate, viscosity and liquidity, and simultaneously has relatively high brightness and vividness.

The invention discloses a water-based ultra-high-speed spraying filter tipping adhesive and a preparation method thereof. The method uses polyvinyl alcohol as a protective colloid, and isomeric alcohol polyoxyethylene ether as an emulsifier to produce a ternary copolymer emulsion of vinyl acetate, methyl methacrylate, and acrylic acid, further improves fluidity and cohesiveness by adding a plasticizer and a polyvinyl alcohol aqueous solution, effectively lowers residual vinyl acetate monomers by vacuuming while stirring under relatively high temperature, and uses ionized water to adjust viscosity, thereby producing the ultra-high-speed spraying filter tipping adhesive suitable for a spraying gluing cigarette making machine. The method does not use any alkylphenol ethoxylates emulsifier which has accumulative harm to human body; and on the premises of low viscosity and low solid content, the produced filter tipping adhesive has high paper adhesion and high drying speed, and can achievestable adhesive supply on the spraying gluing cigarette making machine which is working at a speed of 20000 cigarettes per minute.
