technical field

The invention relates to the technical field of artificial leather, in particular to an anti-radiation reflective artificial leather and a preparation method.

Background technique

Artificial leather is a plastic product that looks and feels like leather and can be used in place of it. It is usually made of fabric as the base, coated with synthetic resin and various plastics. There are mainly two types of PVC artificial leather and PU synthetic leather; usually a fabric is used as the base, and a layer of resin mixture is coated or pasted on it, and then heated to plasticize it, and then rolled, flattened or embossed. product. Similar to natural leather, it has the characteristics of softness and wear resistance. Artificial leather is also used for exterior decoration of car seats, clothing decoration, etc. Therefore, "anti-radiation reflective artificial leather" is proposed in the patent "CN104228194A".
