preparation example Construction

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

[0033]Step 1: Add 25.8-32.7 parts of phenolic alcohol head and 1.1-1.9 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 -0.10MPa, and then heat up to 110- Dehydration starts at 115°C for 1 to 1.5 hours, and the constant temperature is around 115°C. Start to feed the cyclic monomer into the reactor, and feed 271.6-291.4 parts of the cyclic monomer into the reactor, and control the pressure to be less than 0.50MPa. After the passage, keep the temperature at 115-130°C for aging to negative pressure, cool down and discharge , to obtain the prepared polyether.

[0034] Step 2: Add the finished polyether into the reaction kettle, and heat up to 75-80°C by using a water bath. Prepare 6.7-9.3 parts of reducing agent, 3.7-5.6 parts of chain transfer agent, ...

Abstract

The invention provides an efficient adhesive for a resin material and a preparation method thereof. The efficient adhesive is mainly prepared by polymerizing the following components in parts by mass: 25.8 to 32.7 parts of phenol alcohol head, 271.6 to 291.4 parts of cyclic monomer, 1.1 to 1.9 parts of catalyst, 147.8 to 155.3 parts of unsaturated alcohol monomer, 30.7 to 42.9 parts of silane coupling agent, 6.7 to 9.3 parts of reducing agent, 6.2 to 11.4 parts of initiator, 6.4 to 10.9 parts of neutralizing agent, 3.7 to 5.6 parts of chain transfer agent, the rest being deionized water, with the the total mass being 1000 parts. Polyether, unsaturated alcohol ether and a silane coupling agent are taken as reaction raw materials, and an adhesive polymer with ideal molecular structure and performance is prepared by continuously adjusting the dosage of each functional monomer, so that the adhesive prepared by the preparation method disclosed by the invention has better adhesion and adaptability; therefore, the control on the part selection of the raw materials is very important.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to an adhesive for high-efficiency resin materials and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the scientific and technological revolution, the demand for high-performance materials has become more and more extensive. With the development of plastics, resins, and composite materials, the scope of application and durability of materials have been greatly challenged. 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 the fields of home applian...
