Problems solved by technology

However, polyvinyl chloride molecules contain a large number of C-Cl bonds, and there is a large force between the molecules, so it is relatively hard, showing a certain degree of brittleness to the outside, and its poor impact resistance limits its application. modified
In the process of PVC modification, the increase of toughness often leads to the decrease of strength, so the toughness and strength of existing PVC materials cannot meet the requirements of society, and further research and development are needed

Description

technical field [0001] The invention relates to the field of material technology, in particular to a high-strength and high-toughness composite material. Background technique [0002] Polyvinyl chloride is one of the earliest industrialized plastic varieties in the world. As a widely used general-purpose thermoplastic, it has excellent flame retardancy, corrosion resistance, wear resistance, small friction coefficient, low thermal conductivity, and sealing performance. Good, dustproof, sound insulation, earthquake resistance, weather resistance and other advantages, it has a wide range of applications in construction, light industry, agriculture, packaging, daily use and other fields. However, polyvinyl chloride molecules contain a large number of C-Cl bonds, and there is a large force between the molecules, so it is relatively hard, showing a certain degree of brittleness to the outside, and its poor impact resistance limits its application. modified. In the process of PV...
