Alkyl benzoic acid resin manufacturing method

Abstract

The invention relates to an alkyl benzoic acid resin manufacturing method, mainly comprising the following steps: material preparation: dividing the raw materials into two systems: category A and category B, wherein the category A comprises benzene olefin, and R1, R2 and R3 bases of the olefin are alkenes or alkanes with 1-5 carbon atoms, the category B comprises an acids system, comprising propenoic acid, trans-butenedioic acid, cis-butenedioicacid, maleic anhydride, trans-2-butenoic acid, cinnamic acid, trans,trans-2,4-hexadienoic acid and aconitic acid, and taking one or more than one of the components as raw materials; heating: adding the raw materials in a reacting furnace for being heated, wherein the temperature can reach 10-200 DEG C, and the pressure of a reactor is one atmospheric pressure or more than one atmospheric pressure; polymerization: carrying out polymerization reaction of the raw materials in the reactor; and formation: granulating the polymerized resin into particles or sheets by a granulator, or directly cooling the resin into blocks.

Description

technical field [0001] The invention relates to a method for producing an alkyl benzoic acid resin, which belongs to an innovative raw material in the traditional chemical industry and can be widely used in adhesives, rubber products or plastic products. Background technique [0002] If materials are used to mark the development stage of human social civilization, synthetic polymer materials represented by plastics, rubber and fibers in the 20th century have influenced the progress and development of human agriculture, communication, environment, population and health and other fields. [0003] First, in 1907 AD, Leo Bakeland invented Bakelite; in 1920, Hermann Staudinger proposed the concept of polymer and created the term macromolecule. Then polyvinyl chloride began to be used on a large scale; polystyrene and nylon also began to be mass-produced, and then applied to various industrial purposes. After the great development in the 20th century, polymer materials have had a...

Problems solved by technology

It is also soluble in toluene, cyclohexane and other solvents. It can be used as a chelating bridging agent on CR yellow glue and super glue to replace alkyl phenol resin. Since it does not contain formaldehyde carcinogens, it can solve the residual formaldehyde It is an adhesive with better initial adhesion and heat resistance, and improves the adhesion to polar substances such as Nylon and metals and increases heat resistance and strength.
