The invisible car clothes are like the invisible film pasted on the mobile phone. I believe that you reading this article should have the film on your mobile phone. Back then, in the era of spending hundreds of dollars to buy mobile phones, almost no one attached the concept of mobile phone film. However, since the popularity of smart phones represented by apple, the business of mobile phone film is particularly popular. If you don't see a part-time street stall for mobile phone film at night, you can earn more than 10000 yuan a month. Film can be understood as a way to protect what you think is precious. In the past, it was also popular to "over plastic" precious photos. With the popularity of digital cameras and electronic photo albums, the practice of "over plastic" photos almost disappeared.
Now it is popular to stick invisible car clothes to improve the vehicle assurance rate. If you often run on the road, there are more and more small accidents in which the body is scratched, and invisible car clothes are becoming more and more popular. Can the invisible car clothes really protect our car? Can you reduce the probability of being scratched? Master Hua takes you to uncover the mystery of invisible car clothes.
This paper analyzes the value of tieche clothes from the following three aspects:
What is the composition of car clothes? Why do you need car clothes? Is naked car not fragrant? How to choose the right car clothes? What is the composition of car clothes?
看车衣的演变史，探秘现代车衣凭什么来保护车漆车衣的发展史跟世间上大多事物都一样，是从初级到高级的演变过程，车衣最早出现，可以追溯至2011年以前，使用的是PVC材质的车衣，主要的化学成分是聚氯乙烯，大家对聚氯乙烯可并不陌生，聚氯乙烯薄膜被广泛应用在生活的各方面，鞋子鞋业、玩具、雨衣、台布、雨伞等，其缺点非常明显，对光、热的稳定性较差，热分解出放出氯化氢有毒气体。阳光中的紫外线和氧会使聚氯乙烯发生光氧化分解，因而使聚氯乙烯的柔性下降，最后发脆；到了2017年，出现TPH漆膜，实际是高分子的PVC,通过一些添加剂，让PVC薄膜拥有及时性的表现，比如划痕修复、拉伸性、抗污性等,但并没有质的改变，本质依然是年以后， 以TPU单涂层为代表的第三代漆面膜出现,主要成分是热塑性聚氨酯弹性体橡胶，硬度范围相当宽，从Shore A 60~Shore D 80并且在整个硬度范围内具有高弹性；TPU在很宽的温度范围内-40~120℃，具有柔性，而不需要增塑剂。TPU对油类（矿物油，动植物油脂和润滑油）和许多溶剂有良好的抵抗能力；TPU 还有极优的耐高能射线性能；随着人们对漆膜品质越来越强的追求，第四代漆膜，双涂层结构TPU应运而生，在单涂层TPU的基础上，增加更强的防污、防腐蚀、防划痕、抗紫外线。
Look at the evolution history of car clothes and explore what modern car clothes can do to protect car paint. The development history of car clothes is the same as most things in the world. It is an evolution process from primary to advanced. Car clothes first appeared, which can be traced back to before 2011. PVC car clothes are used. The main chemical composition is PVC. Everyone is not unfamiliar with PVC, PVC film is widely used in all aspects of life, such as shoes, toys, raincoats, tablecloths, umbrellas, etc. its disadvantages are very obvious. It has poor stability to light and heat, and releases hydrogen chloride toxic gas through thermal decomposition. Ultraviolet rays and oxygen in sunlight will cause the photooxidative decomposition of PVC, which will reduce the flexibility of PVC and finally make it brittle; In 2017, the TPH film appeared, actually the PVC of polymer. Through some additives, the PVC film has the timeliness performance, such as scratch repair, tensile and anti fouling, but there is no qualitative change. The essence is still after third years, the TPU paint is the representative of the second generation of lacquer mask, the main component is thermoplastic polyurethane elastomer rubber, the hardness range is quite wide. From shore a 60 to shore D 80 and has high elasticity in the whole hardness range; TPU is flexible without plasticizer in a wide temperature range of - 40 ~ 120 ℃. TPU has good resistance to oils (mineral oils, animal and vegetable oils and lubricants) and many solvents; TPU also has excellent high-energy ray resistance; With people's increasingly strong pursuit of paint film quality, the fourth generation paint film, double coating structure TPU came into being. On the basis of single coating TPU, stronger antifouling, corrosion, scratch and UV resistance were added.
It can be seen from the evolution history of car clothes that the reason why car clothes can protect car paint is that the paint film of car clothes is constantly optimizing the materials used.
Why use car clothes?
Putting invisible armor on the car to protect the car paint saves time, labor and money. Pasting invisible car clothes can save the cost and time of daily vehicle maintenance. First of all, the maintenance of vehicles with car clothes becomes easier. They only need simple cleaning, reduce the frequency of car washing and waxing, and do not need crystal plating; Secondly, the car clothes have self heating repair function. The car paint film can be used for 5-10 years. There are small scratches or corrosion by bird excrement, acid rain, poplar catkins, etc. under the strong light of ultraviolet lamp, the original car paint is intact, saving trouble and cost. Of course, if the car body is damaged due to a major accident, the car clothes are mud Bodhisattvas crossing the river, and they have to be scrapped; The third reason is that after the car is marked, the best paint repair masters and processes on the market can not restore the car paint to the original state. So the car clothes can also improve the value preservation rate of the car. For perfectionists, it is more worthwhile to protect the original car paint of your car by sticking film.
