1results about How to "Improve discoloration problem" patented technology

The application relates to the technical field of composite materials, in particular to a composite material capable of keeping the golden appearance of basalt fibers, a preparation method and application thereof. The composite material provided by the application can keep the golden appearance of basalt fibers for a long time and is favorable for the popularization and application of basalt fibers in the fields of automobile interior parts and bags, because the transparent thermoplastic material contained in the composite material can improve the discoloration problem. In addition, the thermoplastic material is added to improve the problems of poor discoloration and poor composite strength, and the process conditions are controlled in the preparation process to improve the discoloration problem, so that the finally-prepared composite material has good durability and does not discolor for a long time. The composite material also has the advantages of environmental protection in the preparation process and simple preparation method.
