有机硅丙烯酸高装饰性建筑涂料研究成果转让本专题利用丙烯酸树脂的耐候性,保光性也十分优异且原料易得的特点,引入有机硅官能单体、硅中间体,所得树脂为成膜物质,加入催化剂后硅氧烷交联,分子间结合十分牢固稳定,所以它的耐热性耐候性,抗氧化性,耐水性十分优异;采用加入对有机硅丙烯酸树脂有稳定作用的溶剂,通过对不同溶剂的选择试验找到合适的溶剂使其具备了好的贮存稳定性。树脂的贮存稳定性好,且涂料在室温交联固化后,克服了热塑型树脂遇热软化而导致耐沾污性差等缺点,得到了硬度高、耐沾污性好、
Acrylic acid and acrylic high decorative architectural coatings research results transfer The topic of the use of acrylic resin weather resistance, excellent gloss retention and easy access to raw materials, the introduction of silicone functional monomers, silicon intermediates, the resulting resin is a film forming material After adding the catalyst, the silicone crosslinks and the intermolecular bonding is very firm and stable, so its heat resistance, weather resistance, oxidation resistance, and water resistance are very good; by adding a solvent that has a stabilizing effect on the silicone acrylic resin, Different solvent selection tests find suitable solvents for good storage stability. The storage stability of the resin is good, and after the coating is cross-linked and cured at room temperature, it overcomes the disadvantages that the thermoplastic resin softens due to heat softening, resulting in poor stain resistance and the like, and has high hardness and good stain resistance.
