Problems solved by technology

Silicone is a commonly used scratch-resistant agent. Generally, the scratch-resistant performance of materials is improved by reducing the friction coefficient. Ordinary silicone-based scratch-resistant agents have poor compatibility with materials and will reduce the surface gloss of high-gloss materials.

Abstract

The invention discloses a scratch-resistant agent for highlight spraying-free PMMA and a preparation method of the scratch-resistant agent. The scratch-resistant agent for highlight spraying-free PMMAcomprises the following components in parts by weight: 40-70 parts of nano zirconium dioxide, 10-30 parts of modified polysiloxane; and 20-50 parts of long-chain alkyl polysiloxane. The invention further discloses a scratch-resistant PMMA composite material. The scratch-resistant agent can effectively improve the scratch resistance of the PMMA surface, and has high long-acting stability, so thatthe workpiece maintains long-lasting excellent surface gloss, and in addition, other comprehensive properties such as demolding of PMMA can be effectively improved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a scratch-resistant agent for high-gloss spray-free PMMA and a preparation method thereof. Background technique [0002] Polymethyl methacrylate (PMMA) is a highly transparent amorphous thermoplastic polymer. It is currently the best polymer transparent material with high mechanical strength and good weather resistance. It is widely used in optical materials, medicine, automobiles, electrical appliances, etc. field, but the surface hardness of PMMA is low, it is easy to be scratched by hard objects, rubbed and loses luster, and its scratch resistance is poor, which has a significant impact on the appearance of the workpiece. With the development of spray-free technology, high-gloss spray-free PMMA is more used in the surface decoration of products, such as automobile grilles, pillars and other parts, which have better aesthetics, so the requirements for surface scratch resistance...
