Problems solved by technology

The solvents of traditional SBS adhesives usually use a large amount of volatile organic solvents, such as toluene, xylene or turpentine, but toluene and xylene are harmful to the human body, while turpentine affects the bonding speed of the adhesive. The above two solvents There are also the following common shortcomings: one is high volatility and pollutes the environment; the other is flammable and explosive, difficult to store and transport, and has poor safety factor; the third is high cost
In order to solve the above problems, the Chinese invention patent with the application number 02138882.2 published on February 26, 2003 and titled "Formulation and Preparation Method of Environmentally Friendly Multifunctional Adhesive" discloses a formula in which non-toxic or low Toxic gasoline is used as the main solvent, and hexane is used as the auxiliary solvent. Its environmental protection effect is better than that of toluene and xylene, and its cost is lower than that of turpentine. However, gasoline is a highly volatile, flammable and explosive substance, which also pollutes the environment and has poor safety factor question

Embodiment 1

[0032] Example 1: The temperature of the reactor was adjusted to 40-60°C, and 3 parts of the compound emulsifier of the block copolymer OP of styrene and butadiene and the anionic emulsifier sodium dodecylbenzenesulfonate, cyclohexane Put 30 parts of alkanes together into the reaction kettle and stir for 3-4 hours to dissolve into a uniform and transparent solution; then lower the temperature in the reaction kettle to 20-25°C, and slowly drop into the solution while stirring the solution (6-8)% 55 parts of polyvinyl alcohol aqueous solution, and then stirred for 1-2 hours, the solution forms a uniform fine white emulsion, and the environment-friendly water-based multifunctional adhesive of the present invention is obtained.

Embodiment 2

[0033] Example 2: Adjust the temperature of the reactor to 40-60°C, add 14 parts of styrene-butadiene block copolymer SBS, 30 parts of rosin glyceride, 14 parts of terpene resin, 4 parts of naphthenic oil, nonionic Type emulsifier OP, 5 parts of compound emulsifier of anionic emulsifier sodium dodecylbenzenesulfonate, and 35 parts of cyclohexane are put into the reaction kettle and stirred for 3-4 hours to dissolve into a uniform and transparent solution; Then lower the temperature in the reaction kettle to 20-25°C, slowly drop 65 parts of (6-8)% polyvinyl alcohol aqueous solution into the solution while stirring the solution, and stir for 1-2 hours, the solution forms a uniform and fine The white emulsion of the present invention obtains the environment-friendly water-based multifunctional adhesive.

Abstract

The invention discloses an environment protection type water craft multifunction adhesive and the manufacture method that includes the following steps: adding SBS, rosin glyceride, terpene resin, naphthenic oil, emulsifying agent, and cyclohexane into reaction vessel to whisking and controlling the temperature at 40-60 degree centigrade to form equal transparent liquid; cooling to 20-25 degree centigrade, whisking the solution and adding 6-8% thickness polyvinyl alcohol water solution. The invention has low solvent content, good performance, asepsis, environment protection and is easy to store and transferring, etc.

Description

technical field [0001] The invention relates to a multifunctional adhesive and a preparation method thereof, in particular to an environment-friendly water-based multifunctional adhesive containing a block copolymer of styrene and butadiene SBS and a preparation method thereof. Background technique [0002] SBS is the abbreviation of block copolymer of styrene and butadiene. Because of its excellent comprehensive performance, it is widely used in the preparation of various adhesives, and is used in interior decoration and furniture manufacturing industries. The solvents of traditional SBS adhesives usually use a large amount of volatile organic solvents, such as toluene, xylene or turpentine, but toluene and xylene are harmful to the human body, while turpentine affects the bonding speed of the adhesive. The above two solvents There are also the following common disadvantages: one is high volatility and pollutes the environment; the other is inflammable and explosive, diffic...
