Title:
INFRARED SHIELDING TYPE EVA HOT MELT ADHESIVE FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/155277
Kind Code:
A1
Abstract:
Disclosed are an infrared shielding type EVA hot melt adhesive film and a preparation method therefor. The hot melt adhesive film comprises 60-80 parts of an EVA main body resin; 10-30 parts of an infrared shielding agent; 5-10 parts of a heat dissipation agent; 8-15 parts of a silane coupling agent; 2-6 parts of cosolvent; 0.1-1 parts of an inorganic flame retardant; 3-10 parts of a tackifier; 0.1-1 parts of an initiator; and 0.01-1 parts of an antioxidant. By means of the action of the infrared shielding agent, infrared rays are shielded or absorbed and light energy is converted into thermal energy, then the thermal energy is isolated on a surface by means of the action of the heat dissipation agent, and shielding and protection against infrared rays are improved; the flame retardancy of a product is improved by means of the action of the inorganic flame retardant; by means of the action of the silane coupling agent, the silane coupling agent is sandwiched between the EVA main body resin and the infrared shielding agent, an organic substrate-silane coupling agent-inorganic substrate bonded layer is formed, and the compatibility of each material is improved.
