AI Technical Summary

Problems solved by technology

With the change of seasons, in some areas, the temperature difference between winter and summer is relatively large. In summer, the temperature is very high, and plastic products are easy to soften. In winter, plastic products become very hard and brittle at around minus 30°C. When it hits the ground, it will break and shatter, causing waste
Currently used plastic products have a relatively narrow operating temperature range, and their use is limited in areas with large temperature differences. Therefore, a plastic with a relatively wide operating temperature is needed, which can be used normally in areas with relatively large temperature differences without causing waste.

Abstract

A low-temperature resistance and high-toughness plastic belongs to the technical field of functional plastic material. The plastic is composed of 100-120 parts of modified polypropylene, 2-5 parts of a plasticizer, 1-3 parts of an anti-oxidant, 1-2 parts of a flexibilizer, 0.5-1.5 parts of a fire retardant, 1-2.5 parts of a heat stabilizer and 3-5 parts of an anti-punching modifier. Plastic products prepared from the formula provided by the invention can not only keep rigidity in summer, but also keep good toughness in cold winter, and is wide in temperature scope and high in toughness.

Description

technical field [0001] The invention relates to a low-temperature-resistant and high-toughness plastic, which belongs to the technical field of functional plastic materials. Background technique [0002] With the increasing use of plastics, there are more and more types of plastic products. Due to the properties of plastics themselves, such as light weight, excellent chemical stability, electrical insulation and poor thermal conductors, the application fields and regions of plastics are becoming wider and wider. With the change of seasons, in some areas, the temperature difference between winter and summer is relatively large. In summer, the temperature is very high, and plastic products are easily softened. In winter, plastic products become very hard and brittle at about minus 30 degrees Celsius. When it hits the ground, it will break and shatter, causing waste. At present, the use temperature range of plastic products is relatively narrow, and the use in areas with larg...
