The invention provides a binder for a
resin composite material and a preparation method of the binder, and the binder is prepared by polymerizing the following components in parts by
mass: 20.8-22.7 parts of a
phenol alcohol head (2-methoxy-6-(2-
propenyl)
phenol), 291.6-311.4 parts of a cyclic
monomer, 0.8-1.6 parts of a catalyst, 137.8-145.3 parts of an unsaturated
alcohol monomer, 24.7-32.9 parts of a
silane coupling agent, 6.1-8.3 parts of a
reducing agent, 5.2-9.4 parts of an initiator, 7.1-11.9 parts of a neutralizing agent, 2.7-4.3 parts of a
chain transfer agent and the balance of deionized water. The total
mass is 1000 parts. The self-made polyether, the unsaturated
alcohol and the
silane coupling agent are used as reaction raw materials, the dosage, the dropwise adding sequence and the dropwise adding time of reaction monomers are well controlled, and the
adhesive polymer with ideal molecular structure and performance is prepared, so that the
polymer has better adhesion and adaptability, and the prepared
adhesive also has more excellent adhesion and adaptability.
