preparation example Construction

[0032] The preparation method of the binder for the resin composite material comprises the following steps:

[0033] Step 1: Add 20.8-22.7 parts of phenolic alcohol head and 0.8-1.6 parts of catalyst into a high-pressure reactor equipped with a stirrer and a thermometer. After nitrogen replacement for 3 times, start vacuuming to gauge pressure -0.15MPa, and then heat up to 130- Dehydration starts at 135°C for 1-2 hours, and the constant temperature is around 125°C. Start to feed the cyclic monomer into the reactor, and feed 291.6-311.4 parts of the cyclic monomer into the reactor, and control the pressure to be less than 0.45MPa. After the passage, keep the temperature at 125-140°C for aging to negative pressure, cool down and discharge, The prepared polyether was obtained.

[0034]Step 2: Add the finished polyether into the reaction kettle, and heat up to 65-80°C by using a water bath. Prepare 6.1-8.3 parts of reducing agent, 4.7-6.5 parts of chain transfer agent, 137.8-145...

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 ...
