preparation example Construction

[0032] The preparation method of the described high-efficiency resin material adhesive comprises the following operation steps:

[0033]Step 1: add 25.8-32.7 parts of phenol alcohol head and 1.1-1.9 parts of catalyst to the autoclave equipped with agitator and thermometer, after 3 times of nitrogen replacement, start vacuuming to gauge pressure-0.10MPa, 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 reaction kettle, feed 271.6-291.4 parts of cyclic monomer into the reaction kettle, and control the pressure to be less than 0.50MPa. After passing through, heat preservation and aging to negative pressure at 115-130 ° C, and cool down for discharging. , to obtain the prepared polyether.

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

Abstract

The invention provides an adhesive for high-efficiency resin materials and a preparation method thereof. 1.9 parts of catalyst, 147.8-155.3 parts of unsaturated alcohol monomer, 30.7-42.9 parts of silane coupling agent, 6.7-9.3 parts of reducing agent, 6.2-11.4 parts of initiator, 6.4-10.9 parts of neutralizing agent, 3.7-5.6 parts Chain transfer agent, the rest is deionized water, the total mass is 1000 parts. In the present invention, polyether, unsaturated alcohol ether and silane coupling agent are used as reaction raw materials, and the adhesive polymer with ideal molecular structure and performance is prepared through continuous adjustment of the dosage of each functional monomer, so that the adhesive polymer prepared by the invention The mixture has better bonding and adaptability, so it is very important to control the selection of raw materials.

Description

technical field [0001] The invention belongs to the technical field of preparation of adhesives, 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 kind of engineering adhesives formulated from epoxy resin binders, 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 appliances,...
