Preparation method and equipment of fully water-soluble high imino partially methylated amino resin

Abstract

The invention relates to the technical field of amino resin production, provides a method capable of preparing full-water-soluble high-imino partial-methylated amino resin which cannot be saturated when the resin is dissolved in water in order to solve the problem that a saturation phenomenon can be produced when the water-soluble resin is dissolved in water, provides equipment which is used for preparing the full-water-soluble high-imino partial-methylated amino resin, has a wide reversing range and good shock insulation effect and can change height of stirring blades according to height change of a material in a container, and solves the problems that a bend is required to be manufactured for reversing under the condition that a direction of a reaction kettle at a feed port and a trend of a feed pipe cannot be adjusted to the same, efficient material stirring and avoidance of a stirring blade idling phenomenon cannot be realized simultaneously during the height change of the material and the shock insulation effect is poor. The preparation equipment comprises the container and a stirrer, wherein the container is provided with shock insulation legs and the feed port adjustable in the feeding direction, the height of each stirring blade of the stirrer is adjustable, and a motor is provided with a terminal.

Description

technical field [0001] The invention relates to the technical field of amino resin production, in particular to a preparation method and equipment for fully water-soluble high imino partially methylated amino resin. Background technique [0002] Water-soluble amino resins are the future development direction of amino resin crosslinking agents. Water is used as a solvent to replace the original organic solvents such as alcohols, which is a huge improvement in terms of environmental protection. At present, countries such as Europe and the United States have banned the use of solvent-based coatings. Although my country's coating industry is still dominated by solvent-based coatings, it is also actively developing towards water-based coatings in recent years. For the future coatings market, water-based coatings are an inevitable trend, and fully water-soluble amino resins that match water-based coatings will inevitably become the main body of amino resin crosslinking agents in t...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a method for preparing a fully water-soluble high-imino partially methylated amino resin that will not produce saturation when dissolved in water, and solves the problem of water-soluble resins prepared by the existing method being dissolved in water. problem with saturation

[0005] The invention also improves a kind of water-soluble high imino partly methylated amino resin preparation equipment with large reversing range, good shock isolation effect and the ability to change the height of the stirring blade according to the change of the height of the material in the container, which solves the existing reaction If the direction of the feed port of the kettle cannot be adjusted to the same direction as the direction of the feed pipe, it is necessary to make an elbow to change the direction, and it is impossible to efficiently stir the material when the height of the material changes without producing stirring blades. Problems of idle phenomenon and poor vibration isolation effect
