对比实施例与对比例1可以看出，在涂料中添加长余辉发光颜料可以使涂料呈现蓝绿色或红色，并且涂料的发射峰强度较高，表明其发光强度较大。
对比实施例1与实施2可以看出，在发光颜料Sr 4Al 14O 25:Eu 2+,Dy 3+中掺Mn 4+可以将发光颜料的颜色从蓝绿色改变为红色，但会稍微削弱发射峰的强度。对比实施例2与实施例3至实施例5可以看出，在发光颜料Sr 4Al 14O 25:Eu 2+,Dy 3+中掺Ca 2+可以提高发射峰的强度，并且随着Ca 2+的掺量在0.002至0.01个范围内的逐渐提高，发射峰的强度逐渐提高。对比实施例2与实施例6至实施例8可以看出，在发光颜料Sr 4Al 14O 25:Eu 2+,Dy 3+中掺适量的Ba 2+可以提高发射峰的强度，Ba 2+在1摩尔Sr 4Al 14O 25:Eu 2+,Dy 3+中的掺量为0.01至0.08摩尔时能够较好地提高发射峰的强度；另外，虽然实施例8的发光颜料的发射峰强度不如实施例2高，但实施例8却相对于实施例1来说改变了发光颜料的颜色并且发光强度下降的程度不大，因此Ba 2+在1摩尔Sr 4Al 14O 25:Eu 2+,Dy 3+中的掺量可以为0.1摩尔。对比实施例1与实施例9、实施例2与实施例10、实施例11可以看出，在在发光颜料Sr 4Al 14O 25:Eu 2+,Dy 3+中掺Mg 2+可以提高发光强度。对比实施例1与实施例12、实施例13可以看出，增加发光颜料的添加量可以延长长余辉发光时间，但也会提高涂料的成本，故在长余辉发光时间满足使用需求的情况下，应尽量选择较少的发光颜料添加量。
此外，长余辉发光材料的添加对涂料的其他性能没有不利影响，本申请实施例制备的涂料均满足使用要求，在此不再一一列出其他性能数据。
