Description
技术领域
本发明涉及涂料领域,特别是涉及一种高粘接力预制型跑道胶黏剂。
背景技术
塑胶跑道又称全天候田径运动跑道。塑胶跑道具有一定的弹性和色彩,具有一定的抗紫外线能力和耐老化力是国际上公认的最佳全天候室外运动场地坪材料。塑胶跑道施工在沥青或水泥基础上,基础做法与道路施工大致相同。基础表面平整度要求较高,以保证塑胶面层厚度一致,弹性均匀。
目前市场上的塑胶跑道分为现浇型和预制型两种。预制型塑胶由于它具有传统预制型塑胶跑道应有的各项使用功能,同时不含橡胶颗粒,无脱粒产生,非常适合频繁使用,安装方便维护简便,维修成本低等特点受到市场的青睐。
传统的预制型塑胶跑道由于聚氨酯胶水与地面的粘合,粘接力不足,在长时间使用的过程中容易脱胶。
发明内容
基于此,有必要提供一种高粘接力预制型跑道胶黏剂。
一种高粘接力预制型跑道胶黏剂,该高粘接力预制型跑道胶黏剂包括如下质量份的各组分:异氰酸酯基硅烷5份至10份、二聚酸二异氰酸酯3份至6份、聚醚多元醇15份至30份、弹性丙烯酸树脂5份至10份、羟乙基纤维素1份至2份、聚已二酸已二醇酯5份至10份、脂类溶剂20份至30份,余量为水。
在其中一个实施例中,所述脂类溶剂包括如下质量份的各组分:乙酸乙酯30份至40份、乙酸丁酯30份至40份、丙酮30份至40份。
在其中一个实施例中,所述聚醚多元醇包括如下质量份的各组分:聚氧化丙烯二醇20份至30份、聚氧化丙烯三醇20份至30份、聚四氢呋喃二醇20份至30份、环氧丙烷聚醚三元醇20份至30份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括抗氧化剂0.01份至0.05份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括分散剂0.3份至0.5份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括紫外线吸收剂0.01份至0.05份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括增稠剂0.1份至0.3份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括防冻剂0.1份至0.5份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括稳定剂0.1份至0.5份。
在其中一个实施例中,所述高粘接力预制型跑道胶黏剂还包括消泡剂0.1份至0.2份。
上述高粘接力预制型跑道胶黏剂,粘接力高、耐候性好、稳定性高、柔韧性好,可以将跑道牢固地粘黏到地面上,在长时间的使用工程中也不会出现脱胶起皮的现象。
附图说明
图1为一个实施例中高粘接力预制型跑道胶黏剂的组分图。
具体实施方式
