Abstract
The invention relates to an alloy material, in particular to an alloy material of long carbon chain nylon and polymethylmethacrylate, which comprises the following components by weight percent: 70-90% of polymethylmethacrylate, 5-25% of long carbon chain nylon, 1-10% of compatibilizer, 0.1-1% of lubricant, 0.1-0.5% of antioxidant and 0.1-0.5% of nucleating agent. The alloy material provided by the invention has the advantages of high transparency, good toughness, good liquidity, high elongation at break and good abrasion resistance, and further extends the application fields of polymethylmethacrylate and long carbon chain nylon, thereby having a wide application prospect.
Description
technical field [0001] The invention relates to an alloy material, in particular to an alloy material of long carbon chain nylon and polymethyl methacrylate. Background technique [0002] Polymethyl methacrylate (PMMA, commonly known as plexiglass), is one of the most transparent polymer materials, with a light transmittance of over 92%, and also has excellent weather resistance, electrical insulation, and good high-temperature performance and processing performance. Therefore, it is widely used in aviation, automobile, construction, instrument and many other fields. However, PMMA has low surface hardness, low wear resistance and scratch resistance, easy to rub hair, poor toughness, low impact strength, and brittleness, which also limits its further application. At present, there are many methods for toughening PMMA, including chemical methods such as copolymerization methods, and physical methods such as blending for modification. Due to the complex process and high cost...
