Description
技术领域technical field
本发明涉及汽车革领域，尤其涉及一种水性无溶剂生物基结合植物基底汽车革及其制备方法。The invention relates to the field of automobile leather, in particular to a water-based solvent-free bio-based combined plant-based automobile leather and a preparation method thereof.
背景技术Background technique
根据现代生活水平的提高，汽车已成基本代步工具；国内汽车成交量步步高升，改装市场日渐庞大，由于车内空间狭小，密闭，导致车内空气质量差。近年来，各国环保意识的不断提高，产品的使用性能包括散发性能日益受到关注的同时，产品对环境的长期影响也逐渐被重视。聚氨酯合成革的生态环保工艺技术目前主要聚焦于水性和无溶剂技术，但其原材料仍主要源于石油基材料，不够环保。According to the improvement of modern living standards, automobiles have become a basic means of transportation; the domestic automobile transaction volume is increasing step by step, and the refitting market is growing day by day. Due to the small and airtight interior space of the car, the air quality inside the car is poor. In recent years, with the continuous improvement of environmental protection awareness in various countries, the use performance of products, including emission performance, has attracted more and more attention. At the same time, the long-term impact of products on the environment has gradually been paid attention to. The ecological and environmental protection technology of polyurethane synthetic leather is currently mainly focused on water-based and solvent-free technology, but its raw materials are still mainly derived from petroleum-based materials, which are not environmentally friendly.
发明内容Contents of the invention
