摘要
选取了4种成分、组成和结构接近,但是拉伸性能有较大差异的弹性乳液,并按照常规配方制备成了4款弹性建筑涂料。研究证明在相同的配方条件下弹性建筑涂料的拉伸性能与弹性乳液的拉伸性能正相关;并且对于玻璃化转变温度和损耗因子形状都接近的弹性建筑涂料,相应温度下损耗因子的值能够反映弹性建筑涂料的拉伸性能。
Four elastomeric emulsions with similar components,compositions and structures but with large differences in tensile properties are selected,and four elastomeric wall coatings are prepared according to conventional formulas.Studies have proved that the tensile properties of elastomeric wall coatings are positively correlated with the tensile properties of elastomeric emulsions under the same formulation conditions;and for elastomeric wall coatings whose glass transition temperature and loss factor shape are both close,the loss factors value at the corresponding temperature are related reflect the tensile properties of elastomeric wall coatings.
