Example Embodiment

[0032] The method of preparing the binder of the resin composite material includes the following operation steps:

[0033] Step 1: 20.8-22.7 parts of the phenol head and 0.8-1.6 parts of the phenol head and 0.8-1.6 parts of the catalyst were added to the high pressure reaction kettle, and the nitrogen replacement was 3 times and then the vacuum to the table pressure -0.15 MPa, then warmed to 130- 135 ° C started dehydration for 1 to 2 hours, and the constant temperature was about 125 ° C. It began to enter the ring monomer to the reactor, into the reaction kettle into the reactor, the control pressure is less than 0.45 MPa, and then heat the aging to the negative pressure at 125-140 ° C after passing through the pass. The polyether was obtained.

[0034]Step 2: Add the obtained finished product to the reactor and heating the water bath to 65-80 ° C. 6.1-8.3 parts of the reducing agent, 4.7-6.3 chain transfer agents and 137.8-145.3 unsaturated alcohol monomers and water were formed...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of binder preparation, and in particular relates to a binder for resin composite materials and a preparation method thereof. Background technique [0002] With the continuous development of the modern scientific and technological revolution, more and more attention has been paid to the performance of special high-performance composite materials and conventional materials. Adhesives have become an effective way to directly combine high-performance materials with different properties. Epoxy resin adhesives are a type of engineering adhesives formulated from epoxy resin base materials, curing agents, diluents, accelerators and fillers. Because of its good bonding performance, good functionality, relatively low price, and simple bonding process, it has been widely used in household appliances, automobiles, water conservancy transportation, electronic appliances, and aerospace industries in recent decades. With ...
