Description

汽车隔热遮阳遮雨布
技术领域
本发明涉及布料领域。更具体地说，本发明涉及一种汽车隔热遮阳遮雨布。
背景技术
汽车是现今最常使用的代步工具，夏季时，当汽车停放于无遮蔽的户外空间并经过阳光的暴晒后，汽车内部会产生高温和有害气体，而且汽车的零部件也会由于高温而损坏，而如果此时需要使用汽车，使用者需将冷气与所有窗户开启，待车内空间散热降温后，方能进入车内；冬季，由于天气寒冷，经常会下雪或霜冻，使汽车的前挡风玻璃上霜盖一层冰霜或雪，无论是清扫、擦抹或使用车内暖风都不能在很短的时间内处理干净，给人们开车出行带来不变。为此，汽车使用者通常需要将一隔热遮阳遮雨布放置于车体上，以阻挡日晒和雨雪对汽车的伤害。
发明内容
本发明的一个目的是解决至少上述问题，并提供至少后面将说明的优点。
本发明还有一个目的是提供一种汽车隔热遮阳遮雨布，其具有防水效果好、结构强度高、隔热、耐寒、防晒的优点。
为了实现根据本发明的这些目的和其它优点，提供了一种汽车隔热遮阳遮雨布，自上至下依次包括：防水层、第一遮阳层、基布层、隔热层、以及第二遮阳层；
所述防水层的厚度为0.3mm，包括以下重量份数的原料：酚醛树脂20份、环氧树脂17份、环氧乙酰亚麻油酸甲酯3份、三甲基锡0.1份、脂肪酸锌0.1份、防水粉4.5份；所述防水粉的制作方法为：将甘油酸酯、二甲聚硅氧烷、脂肪酸甲酯乙氧基化物、水按质量比5:3:0.2:50混合，在45℃下进行乳化反应30min，然后加入占水质量1/3的纳米陶瓷粉，在50℃温度下进行混炼2h，然后收集固态物，烘干即得；
所述第一遮阳层的厚度为0.4mm，包括以下重量份数的原料：炭黑粉10份、氯丁橡胶12份、特氟隆5份、纳米银颗粒1份、纳米氧化铜颗粒0.8份、紫外线吸收剂1.2份；
所述隔热层的厚度为0.4mm，所述隔热层为聚氨酯泡沫层；
所述第二遮阳层的厚度为0.3mm，所述第二遮阳层由70％的PBT塑料和30％的二氧化钛粉末组成；
所述基布层的厚度为0.6mm，由预处理后的剑麻纤维织布制成；其中，预处理后的剑麻纤维的制备方法为：
S1、将剑麻纤维放入质量分数为1.5％的硫酸溶液中，浸泡3h，然后取出放入蒸汽爆破预处理装置中在2.5MPa的压力下处理5min，然后烘干至含水量低于8％，得第一纤维；
S2、将第一纤维放入速冻机中在-18℃温度下冷冻10min，然后取出放入35℃温度的醋酸钠溶液中，3min内持续加热速升温醋酸钠溶液至50℃，然后停止加热继续浸泡2min后取出第一纤维，继续重复速冻机速冻和醋酸钠溶液浸泡速升温步骤3次，得到第二纤维；
