Embodiment 1

[0012] (1) Grind the rosin.

[0013] (2) 50 parts by weight of rosin powder and 50 parts by weight of trioctyl / decyl trimellitate were mixed in the kettle.

[0014] (3) Raise the temperature to 85°C and stir until the rosin is completely dissolved, and cool down to obtain a uniform rosin solution.

[0015] The solution was left standing for 10 days at normal temperature without precipitation.

Embodiment 2

[0017] (1) Grind the rosin.

[0018] (2) 35 parts by weight of rosin powder and 65 parts by weight of trioctyl trimellitate are mixed in the kettle.

[0019] (3) Raise the temperature to 85°C and stir until the rosin is completely dissolved, and cool down to obtain a uniform rosin solution.

[0020] The solution was left standing for 10 days at normal temperature without precipitation.

Embodiment 3

[0022] (1) Grind the rosin.

[0023] (2) 30 parts by weight of rosin powder and 70 parts by weight of tributyl citrate are mixed in the kettle.

[0024] (3) Raise the temperature to 85°C and stir until the rosin is completely dissolved, and cool down to obtain a uniform rosin solution.

[0025] The solution was left standing for 10 days at normal temperature without precipitation.

Abstract

The invention discloses an environment-friendly rosin solution preparation method. Plasticizer trimellitate and citric acid or epoxy grease serve as a solvent, rosin dissolved in the solvent at the temperature of 80-90 DEG C in a stirred manner to obtain rosin solution, and the rosin solution is safe, environmentally friendly, free from toxicity and taste and difficult to volatilization. The usedsolvent has plasticizing and wetting functions, minimum film-forming temperature and glass transition temperature of a compounded latex are reduced, and deflection and flexibility of a glue film are improved, so that wettability and adhesion of a non-polar material are greatly improved. The rosin solution prepared from the selected solvent has environmental friendliness and a plasticizing function, and blending compound of the latex is facilitated.

Description

technical field [0001] The invention belongs to the field of adhesive technology, and in particular relates to a method for preparing an environment-friendly rosin solution. Background technique [0002] Rosin is a non-volatile natural resin obtained from pine rosin through different processing methods. Rosin is an important chemical raw material, widely used in soap, paper, paint, ink, rubber, adhesives, electrical, food and other industries. In recent years, the application of rosin in the field of adhesive technology has increased year by year. In the blending and compounding with water-based environment-friendly latex, the latex is modified so that it has better adhesiveness and initial tack. For non-polar materials such as biaxially oriented polypropylene film BOPP, polyvinyl chloride PVC It has a good effect in pasting leather or PVC film (hard, semi-rigid, soft) and polyethylene film PE with wood, paper, foam products and other materials. However, rosin is a solid ...
