Description

technical field [0001] The invention relates to the technical field of polyurethane circuit board materials, in particular to a polyurethane circuit board material with high toughness and high flame retardancy. Background technique [0002] Polyurethane is known as the "fifth largest plastic" because of its excellent physical and mechanical properties, wear resistance, oil resistance, chemical corrosion resistance, tear resistance, ozone resistance, radiation resistance, strong shock absorption, and good adhesion. It is widely used in light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation and other fields. However, the flame retardancy and toughness of polyurethane materials are not very ideal. When it is used in circuit boards, there are defects in flame retardancy and poor toughness, which limit its application. In order to improve the defects of polyurethane and meet t...
