At present, various base materials are used for preparing spraying-free materials, such as polymethyl methacrylate (PMMA) and acrylonitrile-butadiene-styrene (ABS), wherein the PMMA and the ABS are widely applied to various fields because of the advantages of high glossiness, excellent weather resistance, electric insulation, high surface hardness and the like, and the ABS is a high polymer material with excellent comprehensive performance, high impact strength, good size stability and good solvent resistance. However, they all have significant disadvantages such as low impact strength, poor heat resistance, poor polishability, and low functionality. These drawbacks clearly hinder the potential use of spray-free materials in other fields. Therefore, in order to overcome the drawbacks of the existing materials to obtain a durable and multifunctional spray-free material, a method for obtaining a high-quality spray-free material by simply adjusting and controlling the formula is urgently needed.
