高耐候性涂料组合物、其制备方法及其应用
摘要：
本发明描述的是涂料组合物，其包括颜料和/或填料和作为粘结剂的多级聚乙烯基酯分散体。这些粘结剂通过选择的多步骤方法制备，其中在第一步得到聚乙烯基酯分散体，在第二步将单体以溶解或纯的形式或乳液的形式加至该反应混合物中，且然后再开始聚合反应。该聚乙烯基酯分散体包括聚合的硅烷和/或环氧化物，或该聚乙烯基酯分散体仅具有少量的保护性胶体，如果有的话。用以此方法得到的多级聚乙烯基酯分散体配制的涂料组合物因为非常高的耐候性而值得注意。
摘要（英）：

The invention provides a paint combination, which comprises pigments, multilevel polyvinyl alcohol ester dispersion as binding agent and/or fillings. The binding agent is prepared by the selected multi-step method which comprises: a first step for gaining polyvinyl alcohol ester dispersion; a second step for adding a monomer into the reaction mixture in solvent/pure/emulsion manner to start polyreaction again. The polyvinyl alcohol ester dispersion comprises polymeric silane and/or epoxide or a little protective colloid. The paint combination in the invention is notable for its high resistance to elements.
